In a massive move for the country’s growing climate woes, India is aiming to control weather phenomena like rainfall, lightning, and hail within five years. Dubbed "<keyword id="23131560" type="General" weightage="20" keywordseo="Mission-Mausam" source="keywords">Mission Mausam</keyword>," this government-backed initiative includes the development of <keyword id="23148975" type="General" weightage="20" keywordseo="Mausam-GPT" source="keywords">Mausam GPT</keyword>, a weather AI model designed to enhance prediction accuracy and even manipulate the weather. This would make India one of the first countries to experiment with <keyword id="21369368" type="General" weightage="100" keywordseo="weather-modification" source="keywords">weather modification</keyword> on a significant scale. <h2>Mission Mausam</h2>India’s "Mission Mausam" aims to reshape the future of weather management by using technology to control rain. Over the next 18 months, the government will start with lab simulations to either enhance or suppress rainfall. The ultimate goal, as outlined by Earth Sciences Secretary M. Ravichandran, is to roll out full-scale weather modification within five years. He stated that the initiative could even target events like Independence Day, where “one can think about suppressing rain.” By deploying <keyword id="20644540" type="General" weightage="20" keywordseo="cloud-seeding" source="keywords">cloud seeding</keyword> techniques alongside AI-driven weather prediction tools like "Mausam GPT," the mission seeks to significantly improve India’s ability to manage extreme weather conditions. A key aspect of the plan involves building a robust system of advanced radars, supercomputers, satellites with high-performance sensors, and GIS-based decision support systems. This cutting-edge tech is expected to boost India’s short- and medium-range weather forecasting accuracy by 5-10%, ensuring no event — such as cloudbursts — goes undetected. <div type="Article" hostid="261" msid="113251187" title="India braces for an intensely harsh winter as La Niña takes hold" mstype="2" mssubtype="0"></div>India is not new to weather manipulation efforts. The government has been running pilot projects, such as the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) in Maharashtra, to study cloud properties and enhance rainfall. <h2>Why is weather manipulation necessary and is it safe?</h2>Extreme weather events in India, like deadly floods, droughts, and hailstorms, have noticeably increased in frequency due to <keyword id="19907392" type="General" weightage="20" keywordseo="climate-change" source="keywords">climate change</keyword>. Mission Mausam could potentially give India an edge in combating these disasters. For example, imagine preventing a flood by suppressing rain or creating artificial rain during a drought. India’s investment of Rs 2,000 crore over two years certainly reflects the seriousness of the mission, which is expected to expand further as research progresses. However, weather modification, including cloud seeding, is not without controversy. Globally, cloud seeding has had limited success, with countries like the US, Russia, and China also experimenting with these methods but facing inconsistent results. Even former MoES Secretary Madhavan Rajeevan has noted that “the technology is complex” and still in its developmental stages. <div type="Article" hostid="261" msid="112825937" title="Shivaji Maharaj Statue collapse: Identifying 5 reasons behind the accident" mstype="2" mssubtype="0"></div>Further, the potential downsides can't be ignored. While controlling the weather could save lives, meddling with natural processes is risky. Weather manipulation might have unintended ecological consequences, like shifting rainfall patterns that could harm ecosystems and agriculture. It may also pose geopolitical risks, as neighbouring countries could accuse India of altering weather systems that affect their own climates. Ultimately, while the idea of managing the weather may seem appealing, it opens up a Pandora’s box of environmental and ethical challenges that need careful consideration.

The Indian government is taking steps to control rainfall and weather within five years — is it too risky of a move?

The deadly landslides in Kerala's ecologically fragile Wayanad district were triggered by a heavy burst of rainfall, made 10 per cent heavier by <keyword id="19907392" type="General" weightage="20" keywordseo="climate-change" source="keywords">climate change</keyword>, according to a new rapid attribution study by a global team of scientists. Researchers from India, Sweden, the US and the UK warned that such events will become more common as the climate continues to warm. To measure the impact of human-caused climate change, the scientists from the <keyword id="12008149" type="General" weightage="20" keywordseo="World-Weather-Attribution" source="Orion">World Weather Attribution</keyword> (WWA) group analysed climate models with high enough resolution to accurately reflect rainfall in the relatively small study area. The models indicated that the intensity of rainfall has increased by 10 per cent due to climate change, they said. The models also predict a further four per cent increase in rainfall intensity if the average <keyword id="21951013" type="General" weightage="20" keywordseo="global-temperature" source="keywords">global temperature</keyword> rises by two degrees Celsius compared to the 1850-1900 average. The scientists, however, said there is a "high level of uncertainty" in the model results as the study area is small and mountainous with complex rainfall-climate dynamics. Having said that, the increase in heavy one-day rainfall events aligns with a growing body of scientific evidence on extreme rainfall in a warming world, including in India, and the understanding that a warmer atmosphere holds more moisture, leading to heavier downpours. According to scientists, the atmosphere's capacity to hold moisture increases by about 7 per cent for every one-degree Celsius rise in global temperature. The Earth's global surface temperature has already increased by around 1.3 degrees Celsius due to the rapidly rising concentration of greenhouse gases, primarily carbon dioxide and methane. Scientists say this is the reason behind worsening <keyword id="19912530" type="General" weightage="20" keywordseo="extreme-weather-events" source="keywords">extreme weather events</keyword>, such as droughts, heat waves and floods worldwide. The WWA scientists said that while the relationship between land cover, land use changes and landslide risk in Wayanad is not fully clear from existing studies, factors, such as quarrying for building materials and a 62 per cent reduction in forest cover may have increased the slopes' susceptibility to landslides during heavy rainfall. Other researchers have also linked the <keyword id="22597176" type="General" weightage="100" keywordseo="Wayanad-landslides" source="keywords">Wayanad landslides</keyword> to a combination of forest cover loss, mining in fragile terrain and prolonged rain followed by heavy precipitation. S Abhilash, the director of the Advanced Centre for Atmospheric Radar Research at Cochin University of Science and Technology (CUSAT), had earlier told PTI that the warming of the Arabian Sea is leading to the formation of deep cloud systems, resulting in extremely heavy rainfall in Kerala in a short period and increasing the risk of landslides. "Our research found that the southeast Arabian Sea is becoming warmer, causing the atmosphere above Kerala to become thermodynamically unstable. This instability is allowing the formation of deep clouds," he had said. According to the landslide atlas released by ISRO's National Remote Sensing Centre last year, 10 out of the top 30 landslide-prone districts in India are in Kerala, with Wayanad ranked at the 13th spot. A study published by Springer in 2021 said all landslide hotspots in Kerala are in the Western Ghats region and are concentrated in Idukki, Ernakulam, Kottayam, Wayanad, Kozhikode and Malappuram districts. It said about 59 per cent of total landslides in Kerala have occurred in plantation areas. A 2022 study on depleting forest cover in Wayanad showed that 62 per cent of forests in the district disappeared between 1950 and 2018, while plantation cover rose by around 1,800 per cent.

<ul class="summary-list"><li>Severe weather degrades the accuracy of navigation systems and hampers military operations.</li><li>Climate change has made weather patterns more erratic and harder to forecast.</li></ul>More extreme weather is scrambling the high-tech systems that have given the US military its edge.For example, severe weather can degrade navigation systems such as GPS and sensors on precision-guided munitions. Heavy rain ground aircraft and drones, intense heat exhausts troops, dust storms gum up tank engines, and storms damage ships at sea. Smoke and sandstorms blind aerial drones. Commanders and troops need to have a good idea of what the weather will be like the next day or the next month — forecasts that are getting fouled by the growing unpredictability of weather patterns."Reliably forecasting extreme weather's frequency and intensity to inform strategy is perhaps the most important challenge for the US and allied militaries to adapt to or mitigate a changing climate, because it is imperative that operations and campaigns are feasible meteorologically," warned James Regens in a recent <a target="_blank" href="https://www.rusi.org/explore-our-research/publications/rusi-journal/extreme-weather-risk-military-operations-changing-climate">essay</a> for the Royal United Services Institute, a British think tank.Unexpected weather has always frustrated the best-laid plans of commanders. Had rain not turned the ground muddy the night before the battle, Napoleon might have been able to move up his artillery and win at <a target="_blank" href="https://journals.ametsoc.org/view/journals/bams/74/3/1520-0477_1993_074_0413_ghetws_2_0_co_2.xml">Waterloo</a>. Surprise dust storms crippled helicopters in the daring American operation to <a target="_blank" href="https://www.asomf.org/operation-eagle-claw/">rescue hostages from Iran</a> in 1980. And rain and rough seas almost caused the D-Day landings in June 1944 to be cancelled. But in military meteorology's finest hour, sharp-eyed Allied weathermen were able to <a target="_blank" href="https://www.rmets.org/metmatters/how-weather-forecast-made-history-d-day-landings">forecast a break</a> in the storms that the Germans didn't foresee, which allowed the invasion to achieve tactical surprise.However, these mishaps reflect weather, which is a short-term phenomenon. Climate refers to long-term patterns, including the probability of severe weather. While climate change has become a highly politicized issue, there is general agreement among scientists that the Earth's climate is getting warmer.<div type="image" title="An Iraqi C-130E Hercules photographed during a 2006 sand storm." height="1500" width="2000" msid="110248465" hostid="261" sizebytes="35410"></div>This doesn't mean the weather will be hotter everywhere all the time, but it does indicate that severe weather events — heat, rain, even snow — will be more intense when they happen. One example is California in 2024, which went from years of drought to <a target="_blank" href="https://www.cnn.com/2024/02/19/weather/california-storm-rain-flooding-tuesday/index.html">"atmospheric rivers"</a> that dumped massive amounts of rain that caused mudslides and damaged homes and roads.This can be catastrophic for farmers and people living in flood zones. But it's equally bad for militaries, especially those with advanced capabilities such as the US armed forces, which rely on delicate and interconnected systems that can be degraded by weather.For example, meteorological information is key to the position, navigation and timing (PNT) systems that enable many guided weapons and communications networks to function and coordinate. "Precision fires, aircraft flight operations, surface warship maneuver, ballistic missile trajectories and satellite launch windows to support intelligence collection and communications systems all depend on reliable PNT solutions grounded in meteorological projections," wrote Regens, an intelligence expert and founding partner of Antiphon Solutions, an Oklahoma-based analytics firm.This puts a premium on developing models and technologies that can offer accurate short- and long-term weather forecasts, and do so even as scientific understanding of the impact of global climate change evolves. The strategic implications are profound. For example, knowing the rate at which <a target="_blank" href="https://www.defense.gov/News/News-Stories/Article/Article/3353265/arctic-heating-up-literally-and-as-scene-of-strategic-competition/">Arctic ice is melting</a> — creating new shipping channels and uncovering mineral riches — is of great interest to many nations.Arctic warming creates a "significant homeland defense and national security challenge for US and allied decision-making for North America and NATO's northern flank in Europe," Regens told Business Insider. "Add to this mix the humanitarian missions the US military does in response to floods, monsoons, and other weather problems, and the Pentagon and NATO need to recognize the risk extreme weather in a changing climate poses to military operations."However, Regens points to another problem: getting timely weather forecasts to those who need them. "Military forecasting works fine as long as units have secure network access to near-real time numerically predictive weather information for planning and executing missions," Regens told Business Insider.The problem is that tactical units on the front lines, or in remote areas, often lack the connectivity to receive weather reports. "NOAA [the National Oceanic and Atmospheric Administration], the private sector and universities are actively working to improve global weather models," Regens said. "The missing link is compressing this capability into a tactical package for warfighters.""This requires a major effort to meet the requirements of tactically disaggregated, independently operating units for immediate reliable data," said Regens. "Otherwise, they are going to have limited success firing highly lethal and expensive munitions at significant ranges."

<ul class="summary-list"><li>At least 62 people have been killed in the worst flooding to hit Spain in decades.</li><li>Flash floods are becoming more common and more intense due to global warming.</li></ul>At least 62 people have been killed and many more are missing in the <a target="_blank" class="" href="https://www.businessinsider.com/spain-flooding-51-dead-in-valencia-region-economic-hub-2024-10">worst flooding to hit Spain in decades</a>.Torrential rain hit parts of the country on Tuesday, cutting off main roads, delaying flights, and damaging homes.The rain was the result of a weather phenomenon known as a cold drop, in which cold air moves over warm water.The warm air then rises rapidly, leading to the formation of huge cumulonimbus clouds capable of releasing violent downpours that can devastate towns and cities.Such extreme weather events have a huge human and economic cost — and scientists believe global warming, combined with the way humans have developed the natural landscape, will only make the problem worse.<h2 id="971184fb-8d33-48d1-979d-6445b6e539be">The cost of extreme weather</h2>Estimates for the economic costs of extreme weather and flooding vary, but many tend to agree that they are on the rise.According to the European Environment Agency, extreme weather in Europe caused economic losses of assets estimated at more than $800 billion between 1980 and 2023.Last year, a study by <a target="_blank" class="" href="https://www.theguardian.com/environment/2023/oct/09/climate-crisis-cost-extreme-weather-damage-study">Victoria University of Wellington in New Zealand</a> said the damage caused by the climate crisis through extreme weather has cost $16 million an hour for the past 20 years.<a target="_blank" class="" href="https://www.weforum.org/agenda/2023/01/extreme-weather-economic-cost-wef23/">The World Economic Forum</a> calculated that the cost of extreme events had increased nearly eight times globally, inflation-adjusted, since the 1970s.The impact of flash flooding can be particularly severe because, often, there is very little warning.<h2 id="8409be50-c212-466d-bbd2-62c416ac5204">Flash flooding in dry areas</h2>Flash floods are <a target="_blank" class="" href="https://www.businessinsider.com/what-is-flash-flood-warning-how-to-stay-safe-vermont-2023-7">different from regular flooding</a> because they develop quickly, in the span of a few hours or even minutes.They can be far more devastating in dry areas because parched soil tends to repel water rather than allow it to soak in.That means surges can result from as little as 10 millimeters in just one hour, according to a<a target="_blank" rel="noopener noreferrer" class="c-link"

2023 article in Nature</a>."Our analysis using the Emergency Events Database shows that, since 2000, such regions experienced less than half (47%) of deadly flash floods globally, yet saw almost three-quarters (74%) of related deaths," the authors wrote.The same researchers found that the rate of dryland flash flooding around the world was 20 times higher between 2000 and 2022 than it was between 1900 and 1999.Ernesto Rodríguez Camino, a senior state meteorologist and member of the Spanish Meteorological Association, said flash flooding is becoming more frequent, a trend which is set to continue because of the damaging effects of global warming."Events of this type, which used to occur many decades apart, are now becoming more frequent, and their destructive capacity is greater," he said.<h2 id="c6269754-7554-446d-a63e-b8d93fdbfdc3">Why are there more flash floods?</h2>The Environmental Defense Fund (EDF), a US-based nonprofit, <a target="_blank" class="" href="https://www.edf.org/why-are-floods-hitting-more-places-and-people">said</a> flash flooding has intensified because of increased rainfall and heat waves.The rise in the world's average surface temperature — which was more than 2 Degrees Fahrenheit warmer in 2020 than it was 100 years ago — has resulted in more moisture and clouds in the air, the organization said.According to the EDF, modern infrastructure, including buildings, roads, and sidewalks, has eliminated natural landscape features that would have slowed flooding in the past.It added that stormwater systems designed to protect buildings are often too old and not vast enough to handle the increasing amount of major weather events caused by global warming.Additionally, houses are continuing to be built in areas that are prone to flooding, the organization said.The <a target="_blank" class="" href="https://www.who.int/health-topics/floods#tab=tab_1">World Health Organization</a> (WHO) said people who live on floodplains or in buildings without flood protections or warning systems are most vulnerable.<h2 id="283c598d-eb50-4251-afb8-e7fbf0cb4832">What can be done?</h2><div type="image" title="Emergency workers clear debris the morning after heavy rains and flash floods hit the area on October 30, 2024 in Letur, Albacete province, Spain" height="3333" width="5000" msid="114787520" hostid="261" sizebytes="2262486"></div>Non-environmental factors, such as new infrastructure and better weather warnings, can help prevent the impact of flash flooding.Jess Neumann, an associate professor of Hydrology at the University of Reading, said that a long-term solution would involve the "radical redesign of urban areas.""Flash floods can affect anyone, anywhere. We take preparation for other hazards such as earthquakes and tsunamis very seriously with education, drills, and emergency kits," she said. "It is time we afforded the same to flood risk preparedness."John Marsham, a professor of atmospheric science at the University of Leeds, agrees with Neumann's assessment."Our entire infrastructure and civilization are based around a climate that no longer exists," he said, adding that some locations are becoming more difficult to insure against flood damage.Some cities are already considering better precautions for extreme weather events. For example, in 2022, the US Army Corps of Engineers unveiled its proposal to build a <a target="_blank" class="" href="https://www.nytimes.com/2022/09/26/nyregion/storm-project-new-york-harbor-flooding.html">$52 billion moveable sea barrier</a> along the New York Harbor to protect against storm surges.These protections would also allow local economies to recover faster.The EDF reported that the average flood event from excessive rainfall in the US costs around $4.7 billion.Marsham and Liz Stephens, a professor in climate risks and resilience, said that local governments should also implement stronger warnings about the risks of flash flooding to prevent death and injuries."People shouldn't be dying from these kinds of forecasted weather events in countries where they have the resources to do better," Stephens said.

In the face of an escalating climate crisis, scientists are exploring increasingly unconventional ideas to cool the planet. One of the more intriguing — and surprising — proposals is the use of <keyword id="23626780" type="General" weightage="100" keywordseo="diamond-dust" source="keywords">diamond dust</keyword> injected into the atmosphere to reflect sunlight and reduce global temperatures. A team of climatologists, meteorologists, and <keyword id="19912640" type="General" weightage="20" keywordseo="earth" source="keywords">Earth</keyword> scientists found that injecting synthetic diamond particles might be the most effective way to combat <keyword id="19942740" type="General" weightage="20" keywordseo="global-warming" source="keywords">global warming</keyword>. <h2>Just chill, chill</h2>Global temperatures are rising rapidly, and scientists warn that we may have already reached a tipping point. Simply reducing <keyword id="19951337" type="General" weightage="20" keywordseo="carbon-emissions" source="keywords">carbon emissions</keyword> may no longer be enough. Some experts argue that we need active measures to cool the planet and prevent further catastrophic changes to global weather patterns. One potential solution? <keyword id="23626781" type="General" weightage="20" keywordseo="solar-geoengineering" source="keywords">Solar geoengineering</keyword> — a method that involves injecting <keyword id="23626782" type="General" weightage="20" keywordseo="reflective-particles" source="keywords">reflective particles</keyword>, or aerosols, into the atmosphere to bounce sunlight back into space. Historically, sulphur dioxide has been the leading candidate for this approach. Released naturally by volcanic eruptions, sulphur dioxide is known to have a cooling effect on the Earth by reflecting sunlight. However, the downside of injecting it artificially is significant: it could lead to acid rain, damage the ozone layer, and disrupt weather patterns. <div type="Article" hostid="261" msid="114118159" title="Delhi vs. air pollution: Minister pushes for ‘artificial rains’ in city ahead of Diwali as AQI remains worse than ever" mstype="2" mssubtype="0"></div>The new study aimed to find a better alternative by modelling the impact of seven different materials: calcite, diamond, aluminium, silicon carbide, anatase, rutile, and sulphur dioxide. Their 3D <keyword id="19912529" type="General" weightage="20" keywordseo="climate-models" source="keywords">climate models</keyword> factored in light reflection, how long the particles would stay in the atmosphere, and whether they would clump together — something that could diminish their effectiveness. <h2>Why diamonds?</h2>The surprising result of the research was that diamond dust emerged as the most promising candidate. Tiny synthetic diamond particles proved to be highly effective at reflecting both sunlight and heat, while also remaining suspended in the atmosphere for a sufficient period. Unlike sulphur dioxide, diamonds are chemically inert, meaning they would not react with other atmospheric elements to cause harmful side effects like acid rain. The models suggested that injecting 5 million tons of synthetic diamond dust into the atmosphere annually could reduce global temperatures by 1.6°C over the course of 45 years. This kind of cooling would be enough to counteract some of the most severe effects of <keyword id="19907392" type="General" weightage="20" keywordseo="climate-change" source="keywords">climate change</keyword> and potentially buy time for other long-term solutions. <h2>The cost conundrum</h2>Despite the effectiveness of diamond dust in the simulations, the practical challenge of this approach lies in its cost. Producing and distributing the necessary amount of <keyword id="20001023" type="General" weightage="20" keywordseo="synthetic-diamonds" source="keywords">synthetic diamonds</keyword> would come with an astronomical price tag — an estimated $200 trillion.

While the benefits of <keyword id="23626783" type="General" weightage="20" keywordseo="cooling-the-planet" source="keywords">cooling the planet</keyword> are clear, such a high cost makes this solution far from feasible in the immediate future. <div type="Article" hostid="261" msid="97766424" title="A new climate solution involves shooting moon dust into space to create a &amp;#39;solar shield&amp;#39; around Earth, but scientists say it&amp;#39;s a risky last resort" mstype="2" mssubtype="0"></div>While the diamond dust concept is still in the research phase, the study underscores the urgency of exploring all possible solutions to cool the planet.

In some ways, it makes sense: <a target="_blank" href="https://www.businessinsider.com/summer-2023-heat-wave-tracker-temperature-records-2023-5">rising global temperatures</a> should create milder winters with fewer storms.But in reality, the impact of climate change on winter weather is much more complex.“There’s another influence that we didn’t consider as recently as a decade ago: the way that climate change is occurring can influence the behavior of the polar vortex,” he said.<a target="_blank" href="https://www.businessinsider.com/polar-vortex-dangers-why-it-happens-2019-1">The polar vortex</a> is a large area of low pressure and cold air above the North and South Poles. It’s called a “vortex” because it flows counterclockwise in a continuous circle that keeps this cold air trapped at the poles. Think of it like a <a target="_blank" href="https://www.businessinsider.com/professional-figure-skater-on-how-pain-altered-her-life-2022-2">figure skater</a>, said Cohen. To spin very fast, a figure skater has to tuck her arms, legs, and head into the center of her body. The same thing happens with the polar vortex. When it spins fast, the cold air stays tucked close to the center of rotation.But when the polar vortex slows down, its grip on this cold air loosens. This is what triggers Arctic outbreaks like Lorraine: when cold air in the polar jet stream surges down to lower latitudes.Some loosening and tightening of this grip is normal. The polar vortex tends to weaken in the summer and strengthen in the winter. But climate change is disrupting this cycle. “The way that climate change is happening in the Arctic is favoring this weak polar vortex,” Cohen said. “That’s when you get an increase in the probability of severe winter weather, cold, or snowfall.”Winter storm Lorraine is a direct result of this phenomenon. Last week, the polar vortex was strong and tight. But this week, it stretched out like a rubber band, Cohen said, sending a blast of cold temperatures and snowfall to the East Coast. <h2>Arctic warming is disrupting the polar vortex</h2><div type="image" title="Death Valley in California." height="768" width="1024" msid="107672972" hostid="261" sizebytes="126998"></div>Climate change is increasing global temperatures worldwide. But no place is <a target="_blank" href="https://www.businessinsider.com/un-report-devastating-arctic-temperature-rise-locked-in-2019-3">warming faster than the Arctic</a>. Research suggests that the North Pole has warmed two to four times faster than the rest of the world since 1990.This <a target="_blank" href="https://www.businessinsider.com/polar-vortex-hitting-us-might-be-connected-to-global-warming-2019-1">rapid warming</a> is likely what’s causing more frequent and extreme disruptions to the polar vortex, and unleashing the polar jet stream onto the mid-latitudes, Cohen explained. That’s because rising Arctic temperatures have destabilized the way that air flows around the world. In particular, the warmer temperatures are amplifying a naturally occurring “wave” of air that flows across Eurasia. When this amplified wave crashes into the polar vortex, it disrupts its circulation.When this happens, the US and Canada face the brunt of the wintry blast. “North America is really ground zero for these types of events,” Cohen said.That could explain why the US is still experiencing episodes of record-breaking low winter temperatures despite an overall rise in annual average temperatures, Cohen explained. The year 2023 may have been the hottest year on record, but some states still faced brutal cold. In February of that year, Boston recorded its coldest day since 1957, and Portland, Oregon saw its second snowiest day on record. <h2>Brace for weirder winters</h2><div type="image" title="Snow covers the shore of Joe Pool Lake during a winter storm on January 15, 2024." height="1500" width="2250" msid="107672974" hostid="261" sizebytes="262274"></div>Whiplash weather doesn’t seem to be going away any time soon. With the progression of climate change, the Arctic will continue to warm, and polar vortex disruptions could become increasingly common.“That doesn’t promise that it’s going to continue into the future,” Cohen said. “But a number of these events could continue as long as the conditions that support these disruptions continue.”Adapting to this new normal presents a unique challenge, as the erratic nature of whiplash weather makes it difficult to predict, which adds to the threat it poses to ecosystems, infrastructure, and human health, according to Jennifer Francis, an atmospheric scientist at Woodwell Climate Research Center. Demands for heat and electricity can shift drastically. And people can find themselves suddenly caught in dangerous conditions.“After a long dry spell, a sudden flip to heavy precipitation may catch people and communities unprepared,” Francis told BI in an email. And as climate change continues to warm the Arctic, Francis anticipates we will see more of these events.“Unless we can quickly and drastically reduce greenhouse gas emissions, we'll see a very distinct increase in weather whiplash events in decades to come,” Francis wrote.

You can try to cross-check flood risk with other sources like seeing if the town or city has flood maps available."Everything that we're offering are probabilistic risk estimates," Porter said."I think that just in general, the models give you a pretty good indication of which properties are riskier than other properties," he added.<h2 id="ea2c710b-3a7a-45fe-b58f-971596d4b019">Then check local building codes…</h2>Once you know the climate risks, you can assess <a target="_blank" class="" href="https://www.businessinsider.com/photos-why-some-homes-survive-hurricanes-lessons-homeowners-2024-10">how well a property is built</a> to withstand them.<div type="image" title="slumping one-story grey and wood panel house with panels ripped away next to a standing yellow house" height="1500" width="2249" msid="114374424" hostid="261" sizebytes="407800"></div>A good indicator of that is the local building code and whether the house is built to its standards.

In 1989, a geomagnetic storm wiped out Quebec's electricity and caused other power-system issues in the US, UK, and Sweden.Nothing that major has happened in a while. But this solar maximum has been one for the books. In May, an <a target="_blank" rel="" href="https://www.businessinsider.com/photos-northern-lights-dazzle-night-sky-across-the-us-europe-2024-5">extreme geomagnetic storm </a>brought the northern lights as far south as Arkansas.<div type="image" title="northern lights night sky with pink and purple glow above silhouette of treetops" height="1500" width="2000" msid="114291826" hostid="261" sizebytes="115744"></div>It was "the strongest solar storm to reach Earth in two decades and possibly one of the strongest displays of auroras on record in the past 500 years," said Elsayed Talaat, the director of the Office of Space Weather Observations at the National Oceanic and Atmospheric Administration.Unlike two decades ago, NOAA can better <a target="_blank" class="" href="https://www.businessinsider.com/coronal-hole-on-sun-blasts-solar-wind-toward-earth-2023-3">forecast geomagnetic storms</a> and industries can prepare for them before they strike. Still, the May solar storm disrupted high-precision GPS that some US farmers rely on, causing about $500 million in losses, according to Bill Murtagh, a program coordinator at NOAA's Space Weather Prediction Center."The bigger the storm, the more visible the aurora, the further south it's visible. At the same time, we can't be hoping for these big displays because with them comes the threat to our critical infrastructure," Murtagh said during Tuesday's announcement.

The sun is at its 11-year maximum. That means another year of eruptions that can endanger satellites, ground flights, and spark stunning auroras.
