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. <br /><br /> This comes despite rapid growth in renewable energy and a landmark agreement at COP28 in Dubai last year to move away from fossil fuels. <br /><br /> 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. <br /><br /> "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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> 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. <br /><br /> Technology-based CO2 removal accounts for only a tiny fraction -- around one-millionth -- of CO2 emissions from fossil fuels. <br /><br /> 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. <br /><br /> Land and ocean carbon sinks continued to absorb around half of the total carbon emissions, despite being negatively affected by climate change.

When it comes to talking to children, many of us might instinctively simplify or even "dumb down" our language. But treating kids like they’re incapable of handling complexity can be more damaging than we realise. This practice, often labelled as "<keyword id="23912121" type="General" weightage="20" keywordseo="infantilisation" source="keywords">infantilisation</keyword>," stems from a form of age-based bias known as <em>adultism</em>, where society assumes that children lack the capability to engage meaningfully with complex issues. Yet, research increasingly suggests that children, if given the chance, can think critically, contribute insights, and show remarkable understanding — even on major topics like environmental ethics and social justice.<br /><h2>Full-fledged citizens</h2>Infantilising children can have several negative consequences, including undermining their self-confidence, stifling independence, and causing emotional dependence. Natalie M. Fletcher, a philosophy professor, argues that infantilising children restricts their potential to become active contributors in society. "Children are full-fledged citizens and not just future members of society," she points out. She highlights that children often have valuable perspectives, particularly on issues like friendship, where their thoughts are sometimes more nuanced than adults’ because these relationships are central to their lives.<br /><br />In her work, Fletcher emphasises that denying children the chance to engage in thoughtful dialogue can lead to the exclusion of a valuable dimension of knowledge and understanding, limiting society as a whole. Encouraging philosophical dialogue in children can empower them to see themselves as agents of change rather than passive future citizens.<br /><h2>Kids need complex conversations</h2>Infantilisation not only hinders mental and emotional development but also impacts children's ability to think independently. Experts warn that children constantly treated as incapable of handling complexity may struggle to develop essential skills like critical thinking and self-reliance. They might become overly dependent on authority figures, leading to low self-esteem and a reduced sense of autonomy as they mature. Encouraging children to express themselves and engage with challenging topics, on the other hand, supports their social and emotional growth, fostering resilience and independence.<br /><br />Additionally, infantilising children often stems from a desire to shield them from life’s complexities, particularly from “adult” topics like <keyword id="6361617" type="General" weightage="20" keywordseo="climate-change" source="Orion">climate change</keyword>. Fletcher argues, however, that children should be allowed to discuss issues like environmental justice, as they are the ones who will ultimately inherit the outcomes of today’s decisions. Children dealing with eco-anxiety, for example, benefit from having open dialogues about environmental concerns, which helps them feel empowered rather than overwhelmed.<br /><h2>Raising independent thinkers, not passive followers</h2>In Fletcher’s educational charity, Brila, children as young as five engage in philosophical discussions that promote critical thinking and active listening. This approach has been shown to help children view themselves as proactive thinkers. While parents may feel compelled to protect their kids from "too much too soon," providing age-appropriate explanations can prevent feelings of helplessness, giving kids the tools they need to become thoughtful, capable adults.<br /><br />As adults, fostering independence and <keyword id="23912120" type="General" weightage="20" keywordseo="critical-thinking-in-children" source="keywords">critical thinking in children</keyword> means embracing their ability to understand more than we may expect. Treating kids like the complex, capable individuals they are doesn't just support their growth — it strengthens society as a whole. Encouraging kids to share their thoughts and respecting their input can lead to a future generation that's better equipped to face and solve the challenges of tomorrow.<br />

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>.<br /><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.<br /><br />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.<br /><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.<br /><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.<br /><br />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.<br /><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.<br /><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.

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.<br /><br />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.<br /><br />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.<br />  <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.<br /><br />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.<br /><br />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>.

No, she’s not literally stuck — her return is finally scheduled for February of next year. But in the nine months that Williams will spend in space, her body will have undergone a series of changes that are both fascinating and concerning.<br /><h2>Muscle and bone loss</h2>In space, everything changes — especially when it comes to the human body. The lack of gravity aboard the International Space Station (<keyword id="20307956" type="General" weightage="20" keywordseo="ISS" source="keywords">ISS</keyword>) means that Sunita’s muscles and bones haven’t been working as hard as they would on Earth. Without the constant pull of gravity, astronauts experience muscle atrophy and significant <keyword id="22641237" type="General" weightage="20" keywordseo="bone-density-loss" source="keywords">bone density loss</keyword> — sometimes losing as much as 1% of bone mass per month. Upon her return, Sunita will likely undergo a rigorous rehabilitation program to help her regain strength and bone density.<br />  <div type="Article" hostid="261" msid="111640507" title="Stranded in space: Sunita Williams shares her experience LIVE from the International Space Station" mstype="2" mssubtype="0"></div><h2>The eyes have it</h2>One of the lesser-known but more intriguing effects of long-term <keyword id="21352806" type="General" weightage="20" keywordseo="space-travel" source="keywords">space travel</keyword> is its impact on vision. Astronauts often suffer from what’s known as Spaceflight-Associated Neuro-ocular Syndrome (SANS), a condition where fluid shifts in the body cause pressure on the optic nerve, leading to changes in eyesight. Sunita’s vision might be temporarily impaired, requiring monitoring and possibly corrective measures when she’s back on Earth.<br /><h2>Fluid shift and swollen head</h2>In the <keyword id="20966007" type="General" weightage="20" keywordseo="microgravity" source="keywords">microgravity</keyword> of space, fluids in the body redistribute, leading to what’s often described as the “puffy face and chicken legs” — a phenomenon where fluids like blood shift towards the upper body in the absence of hydrostatic pressure. This fluid shift also causes increased pressure on the brain, which can affect cognitive function and lead to headaches. Sunita will need time to readjust to Earth’s gravity as these fluids return to their normal distribution. Fortunately, these fluid levels return to normal within three days of returning to Earth.<br /><h2><keyword id="20434423" type="General" weightage="20" keywordseo="radiation" source="keywords">Radiation</keyword> and the DNA dilemma</h2>Space is a hostile environment in more ways than one. The ISS offers some protection from cosmic radiation, but Sunita has still been exposed to levels much higher than on Earth. This radiation can damage DNA, increasing the risk of cancer and other health issues down the line. Her cells might show signs of molecular changes, and she will likely be under medical surveillance for years to monitor any long-term effects.<br /><h2>Mental and emotional strain</h2>Spending extended periods in space is also mentally taxing. Isolation, confinement, and distance from Earth can take a toll on an astronaut’s psychological well-being. In fact, astronauts receive significant mental training to steel themselves for time in space. Many astronauts also indulge in regular social activities such as movie and game nights to ease their stress during this time.<br /><h2>What caused her delayed return?</h2>Sunita Williams' return from the International Space Station (ISS) has been delayed due to issues with the Boeing Starliner spacecraft, which was initially planned to bring her back to Earth. Technical challenges with the Starliner’s thrusters and other systems have caused <keyword id="19935155" type="General" weightage="20" keywordseo="NASA" source="keywords" meta.keywordsubtype="org" meta.entityname="NASA" meta.hostid="261" meta.entityid="NASA">NASA</keyword> and Boeing to conduct additional reviews and tests to ensure the spacecraft's safety before it is cleared for the return journey.<br />  <div type="Article" hostid="261" msid="112547125" title="An astronaut stuck on the International Space Station due to Boeing Starliner delays is roughing it in a sleeping bag over in the Japanese space module" mstype="2" mssubtype="0"></div>After many delays and considerations, NASA has confirmed that they plan to bring Williams back on the SpaceX Crew-9 mission, which is scheduled for February 2025. This would involve some adjustments, including launching Crew-9 with only two members instead of the usual four, to accommodate Williams and her fellow astronaut Butch Wilmore.<br /><br />The delay has left Williams and Wilmore aboard the ISS longer than initially planned. Despite this, NASA has assured that they are well-prepared for an extended stay, with sufficient supplies of food, clothing, and oxygen. Additionally, the ISS regularly receives resupply missions to ensure all astronauts have what they need.<br />
