New Delhi: India's fossil fuel emissions are projected to rise by 4.6 per cent in 2024, while China could see a marginal rise of 0.2 per cent, according to new research by a group of international scientists. As the UN climate conference in Baku, Azerbaijan, discussed raising trillions of dollars to tackle <keyword id="19907392" type="General" weightage="20" keywordseo="Climate-change" source="keywords">climate change</keyword>, the group of scientists known as the "Global Carbon Project" warned that emissions from fossil fuels -- the main driver of warming -- could hit a record 37.4 billion tonnes in 2024, up 0.8 percent from 2023 levels. This comes despite rapid growth in renewable energy and a landmark agreement at COP28 in Dubai last year to move away from fossil fuels. The "<keyword id="23948569" type="General" weightage="20" keywordseo="Global-carbon-budget-2024" source="keywords">Global Carbon Budget 2024</keyword>" report said total global CO2 emissions are set to go up from 40.6 billion tons in 2023 to 41.6 billion metric tons in 2024, which is on course to become the warmest year on record. "The impacts of climate change are becoming increasingly dramatic, yet we still see no sign that burning of fossil fuels has peaked," Professor Pierre Friedlingstein of Exeter's Global Systems Institute, who led the study, said. The 'Global Carbon Project' team said India, the world's most populous country and fastest-growing major economy, may see its fossil fuel emissions rise by 4.6 percent. According to a UN report released last month, India's greenhouse gas emissions surged by 6.1 per cent in 2023, contributing to 8 per cent of the global total. However, the country's historical contribution to global CO2 emissions stands at only 3 per cent. India's per capita emissions remain low at 2.9 tons of CO2 equivalent (tCO2e), far below the global average of 6.6 tCO2e. India, the world's third-largest greenhouse gas emitter, has pledged to reach net zero emissions (balancing emissions with removals) by 2070 and aims to achieve 500 gigawatts of renewable energy capacity by 2030. China's emissions, which make up 32 per cent of the global total, are likely to increase slightly by 0.2 per cent, though there is a chance they could decline, according to the data released on Wednesday. Emissions from the United States and the European Union, which contribute 13 per cent and 7 per cent of the global total, are both set to decline, with drops of 0.6 per cent for the US and 3.8 per cent for the EU. Emissions from the rest of the world, which together account for 38 per cent of global emissions, could see a rise of 1.1 per cent. The researchers said that in 2024, coal emissions will likely increase by 0.2 per cent, oil by 0.9 per cent, and gas by 2.4 per cent, globally. Coal, oil, and gas contribute 41 per cent, 32 per cent, and 21 per cent of global fossil CO2 emissions, respectively. However, given the uncertainty in projections, it remains possible that coal emissions could decline in 2024, they said. The report also pointed out that emissions from international aviation and shipping, which account for 3 per cent of global emissions and are tracked separately from national or regional totals, are expected to rise by 7.8 per cent in 2024. However, these emissions will still be 3.5 per cent below the 2019 pre-pandemic levels. Globally, emissions from land-use changes, like deforestation, have dropped by 20 per cent over the past decade but are expected to rise in 2024. Permanent CO2 removal through reforestation and new forest planting now offsets about half of the emissions from permanent deforestation, they added. Technology-based CO2 removal accounts for only a tiny fraction -- around one-millionth -- of CO2 emissions from fossil fuels. The report said that emissions from fires in 2024 have been above the average since the beginning of the satellite record in 2003, particularly due to the extreme 2023 wildfire season in Canada (which continued into 2024) and severe drought in Brazil. Land and ocean carbon sinks continued to absorb around half of the total carbon emissions, despite being negatively affected by climate change.

Global fossil emissions to reach record high in 2024; India's share to rise by 4.6 pc: Report

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. To put that into perspective, that’s roughly double the size of the global economy in 2023. 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.

Diamonds in the Sky: Scientists want to inject diamonds into our atmosphere to cool the planet!

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.

This interactive map showcases <keyword id="22576002" type="General" weightage="20" keywordseo="CO2-concentrations" source="keywords">CO2 concentrations</keyword> as they shifted through Earth's atmosphere from January to March 2020, influenced by wind patterns and atmospheric circulation. With its exceptional detail, you can zoom in to pinpoint CO2 emissions rising from power plants, fires, and urban areas, as they spread across continents and oceans. Over India, you can see the greenhouse gas blowing over from neighbouring continents and also originating from the subcontinent. The pulsating oranges indicate CO2 concentrations of 420-460 ppm over India. <h2>The sources of CO2 </h2>One of the most striking features of the map is its ability to zoom in on specific regions, allowing viewers to see CO2 emissions rising from individual cities and industrial complexes. This level of detail provides a clear and compelling picture of human activities' impact on the environment. The map highlights distinct emission patterns across different regions. In China, the United States, and South Asia, power plants, industrial facilities, and vehicles were the primary contributors to CO2 emissions. Conversely, in Africa and South America, fires ignited by land management practices, agricultural burning, and deforestation, along with the combustion of oil and coal, were the main sources. <h2>Pulsating gases</h2>The map also highlights the role of natural systems in the carbon cycle. Forests, oceans, and other ecosystems absorb vast amounts of CO2, acting as vital carbon sinks. However, the visualisation also reveals how human activities are overwhelming these natural systems, leading to a buildup of CO2 in the atmosphere. Further, the map exhibits a pulsating appearance. This is because, firstly, fires typically intensify during daylight hours and subside at night, creating a diurnal pattern. Secondly, the absorption and release of CO2 by plants during photosynthesis and respiration contribute to the fluctuations. This pulsing effect is particularly noticeable in regions with abundant vegetation, such as mid- to high-latitude forests and tropical areas. <div type="Article" hostid="261" msid="112021374" title="Scientists found a groundbreaking new reason to plant more trees" mstype="2" mssubtype="0"></div>“This map is a powerful tool for understanding the scale and complexity of the climate crisis,” said [Quote from NASA scientist]. “It shows us where the biggest problems are and where we need to focus our efforts to reduce emissions.” The data behind the map comes from NASA's <keyword id="22576004" type="General" weightage="20" keywordseo="goddard-earth-observing-system" source="keywords">Goddard Earth Observing System</keyword> (GEOS), a sophisticated model that simulates Earth's atmosphere with incredible detail.

A recent <a href="https://academic.oup.com/mnrasl/article/535/1/L18/7760380">study</a> has revealed an unexpected consequence of the global lockdowns imposed in 2020 to curb the spread of COVID-19: a measurable cooling of the <keyword id="19899207" type="General" weightage="20" keywordseo="moon" source="keywords">Moon</keyword>'s surface. Indian researchers from the <keyword id="20178202" type="General" weightage="20" keywordseo="Physical-Research-Laboratory" source="keywords" meta.keywordsubtype="org" meta.entityname="Physical Research Laboratory" meta.hostid="261" meta.entityid="Physical Research Laboratory">Physical Research Laboratory</keyword> (PRL) analysed night-time temperatures at six different locations on the Moon's near side between 2017 and 2023. Using data from NASA's Lunar Reconnaissance Orbiter, they discovered a consistent temperature drop of 8-10 Kelvin during the strictest lockdown period of April-May 2020 compared to previous years. For instance, the coldest temperature was recorded in 2020, with a value of 96.2 K at one location. In contrast, post-lockdown years like 2021 and 2022 saw a gradual warming trend as human activity resumed. <div type="Article" hostid="261" msid="111772552" title="Newly discovered Moon caves could shelter astronauts as they set up lunar bases!" mstype="2" mssubtype="0"></div>The researchers posit that this unusual cooling can be attributed to a reduction in Earth's outgoing radiation during the lockdowns. As human activity slowed down, <keyword id="20107362" type="General" weightage="20" keywordseo="greenhouse-gas-emissions" source="keywords">greenhouse gas emissions</keyword> and aerosols decreased significantly. This meant less heat was trapped and re-emitted by Earth's atmosphere, resulting in a measurable decrease in the radiation reaching the Moon. Further, the Moon's surface acts as an amplifier of Earth's radiation signature. And this unique global event provided a rare opportunity to observe how changes in human activity on Earth can affect our nearest celestial neighbour. While the study presents a compelling correlation, the authors acknowledge that more data is needed to definitively establish the link between Earth's radiation changes and <keyword id="23366659" type="General" weightage="100" keywordseo="lunar-surface-temperatures" source="keywords">lunar surface temperatures</keyword>.

The Covid lockdowns did WHAT to the Moon?!

With millions of people across five continents experiencing scorching heat last month, the European Union's (EU) climate agency, Copernicus <keyword id="19907392" type="General" weightage="20" keywordseo="climate-change" source="keywords">Climate Change</keyword> Service (C3S), confirmed on Monday that June was the warmest on record. It also marked the 12th consecutive month of <keyword id="20524196" type="General" weightage="20" keywordseo="global-temperatures" source="keywords">global temperatures</keyword> reaching <keyword id="22325521" type="General" weightage="20" keywordseo="1-5-degrees-Celsius" source="keywords">1.5 degrees Celsius</keyword> above the pre-industrial average. According to scientists at C3S, every month since June last year has been the warmest such month on record. In January, the world completed an entire year with the mean surface air temperature exceeding the 1.5-degree Celsius threshold. June was the 12th consecutive month with monthly average temperatures above the 1850-1900 pre-industrial average. At the 2015 UN climate talks in Paris, world leaders committed to limiting the global average temperature rise to 1.5 degrees Celsius above the pre-industrial period to avoid the worst impacts of climate change. However, a permanent breach of the 1.5-degree Celsius limit specified in the <keyword id="20104670" type="General" weightage="20" keywordseo="Paris-Agreement" source="keywords">Paris Agreement</keyword> refers to long-term warming over a 20 or 30-year period. Earth's global surface temperature has already increased by around 1.2 degrees Celsius compared to the average in 1850-1900 due to the rapidly-increasing concentration of <keyword id="20649149" type="General" weightage="20" keywordseo="greenhouse-gases" source="keywords">greenhouse gases</keyword> -- primarily carbon dioxide and methane -- in the atmosphere. This warming is considered to be the reason behind record droughts, wildfires and floods worldwide. According to new data, June 2024 was the warmest on record, with an average surface air temperature of 16.66 degrees Celsius, 0.67 degrees Celsius above the 1991-2020 average for the month and 0.14 degrees Celsius above the previous high set in June 2023. "The month was 1.5 degrees Celsius above the estimated June average for 1850-1900, the designated pre-industrial reference period, making it the 12th consecutive month to reach or break the 1.5-degree threshold," C3S said in a statement. It was also the 13th consecutive month of <keyword id="21477127" type="General" weightage="20" keywordseo="record-high-temperatures" source="keywords">record-high temperatures</keyword>, a result of the combined effect of the 2023-24 El Nino event and human-caused climate change. While unusual, a similar streak of monthly global temperature records happened previously in 2015-16. "This is more than a statistical oddity and highlights a large and continuing shift in our climate. Even if this specific streak of extremes ends at some point, we are bound to see new records being broken as the climate continues to warm. This is inevitable, unless we stop adding greenhouse gases into the atmosphere and the oceans," said Carlo Buontempo, the director of C3S. The European climate agency said the global average temperature for the last 12 months (July 2023-June 2024) is the highest on record, at 0.76 degrees Celsius above the 1991-2020 average and 1.64 degrees Celsius above the 1850-1900 pre-industrial average. The world's sea surface in June was also the highest ever recorded for the month. Several countries experienced record-breaking heat and devastating floods and storms in June. According to an analysis by Climate Central, an independent group of scientists and communicators based in the United States, more than 60 per cent of the world population faced extreme heat that was made at least three times more likely by climate change during June 16-24. Climate Central said the blistering heat in June impacted 619 million (61.9 crore) people in India, 579 million (57.9 crore) in China, 231 million (23.1 crore) in Indonesia, 206 million (20.6 crore) in Nigeria, 176 million (17.6 crore) in Brazil, 171 million (17.1 crore) in Bangladesh, 165 million (16.5 crore) in the US, 152 million (15.2 crore) in Europe, 123 million (12.3 crore) in Mexico, 121 million (12.1 crore) in Ethiopia and 103 million (10.3 crore) in Egypt. According to the India Meteorological Department (IMD), northwest India recorded its warmest June since 1901. India, which experienced one of its hottest and longest heatwaves, recorded more than 40,000 suspected heatstroke cases and over 100 heat-related deaths. The intense heat overwhelmed the water supply system and power grids, with Delhi grappling with a severe water crisis. According to the IMD, 11 states recorded 20 to 38 heatwave days -- up to four times the usual number of such days -- during the April-to-June period. The mercury breached 50 degrees Celsius in parts of Rajasthan, with night temperatures hovering around 35 degrees Celsius in many places. Temperatures were most above average over eastern Canada, the western United States and Mexico, Brazil, northern Siberia, the Middle East, northern Africa, and western Antarctica.
