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>.

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.<br /><br />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.<br /><h2>The sources of CO2<br /></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.<br /><br />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.<br /><br /><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.<br /><br />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.<br />  <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.”<br /><br />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.

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.

In addition to a socio-economic stock take, the comprehensive report also outlines the strides India has made on the environment and climate fronts last year.<br /><br />India is in a weird grey area when the climate blame-game is concerned. We continue to average some of the lowest per capita CO2 emissions in the world. But, being the most-populous country in the world, these small bits add up to make India the third-largest emitter of CO2 in the world, after China and the United States.<br /><div type="Article" hostid="261" msid="111923746" title="Economic Survey 2023-2024 highlights emerging job trends in AI, Cybersecurity, 3D Printing and Web Development" mstype="2" mssubtype="0"></div>However, this is not to say that the country has been sitting the green transition out either. As highlighted in the Economic Survey, India has been making notable strides in tackling climate change and promoting <keyword id="19895783" type="General" weightage="20" keywordseo="sustainability" source="keywords">sustainability</keyword> — efforts that will be crucial to protect billions in the coming years and decades. Let's take a look at these efforts and compare them with findings from other recent environmental reports to see the full picture.<br /><h2><keyword id="21818512" type="General" weightage="20" keywordseo="emission-intensity" source="keywords">Emission intensity</keyword> reduction</h2>The economic survey proudly states that India has reduced the emission intensity of its GDP by 33% from 2005 levels by 2019. This means the country is producing less greenhouse gas for every unit of economic activity.<br /><br />This is a commendable achievement because India’s original climate change target — or Nationally Determined Contribution — was set to precisely 33% reduction of emission intensity by 2030, before being revised to 45% in 2022. While the jump from 33% to 45% is still a significant one with barely half a decade to go, this progress is a clear sign that India’s climate policies are having a real impact.<br /><h2><keyword id="19895602" type="General" weightage="20" keywordseo="renewable-energy" source="keywords">Renewable energy</keyword> capacity</h2>According to the economic survey, 45.4% of India’s installed electricity generation capacity — which includes solar, wind, and hydropower — now comes from non-fossil sources, as of May 31, 2024. <br /><div type="Article" hostid="261" msid="111774972" title="Economic Survey shows India&amp;#39;s energy needs to grow 2.5x, healthy growth in formal employment" mstype="2" mssubtype="0"></div>As per reports by the Ministry of New &amp; Renewable Energy, India added a record renewable energy capacity of 18.48 GW in 2023-2024, with solar installations amounting to 12.78 GW, followed by 2.27 GW of wind energy. However, industry experts have also noted that India Inc. cannot afford to run out of steam now, and must continue to add at least 50 GW for the next six years to meet the target of 500 GW of renewables by 2030.<br /><h2>Indian energy needs</h2>India's energy needs are expected to grow 2 to 2.5 times by 2047, as per the latest economic survey. This necessitates a balanced approach to <keyword id="19951336" type="General" weightage="20" keywordseo="energy-transition" source="keywords">energy transition</keyword> that considers resource limitations and the need for resilience to climate change.<br /><br />India has suffered from an overdependence on coal and fossil fuels in the past, accounting for around 75% of total energy generation in 2021, as per the Energy Information Administration. However, this number has been quickly falling, even dropping below a historic 50% in Q1 2024.<br /><h2>Sovereign <keyword id="20177085" type="General" weightage="20" keywordseo="green-bonds" source="keywords">green bonds</keyword></h2>To fund green projects, India issued Rs 16,000 Crore in sovereign green bonds — financial instruments that support green projects at lower capital costs — in early 2023 and another Rs 20,000 Crore later in the year, the economic survey reports. As per the government, these proceeds were utilised in many eco-friendly projects, such as New and Renewable Energy, Environment, Forests and Climate Change, Housing and Urban Affairs, Railways. To widen the investor base, the <keyword id="19899810" type="General" weightage="20" keywordseo="reserve-bank-of-india" source="keywords">Reserve Bank of India</keyword> (RBI) also recently permitted eligible foreign investors to invest in such bonds.<br /><h2>Mission LiFE and Green Credit Programme</h2>The survey also talks extensively about Mission LiFE (Lifestyle for Environment), which promotes sustainable living, and the Green Credit Programme (GCP), which incentivises eco-friendly actions by offering “green credits”.<br /><br />In the past few months, Madhya Pradesh, Telangana and a few other states have reportedly approved thousands of hectares of degraded forest land for greening exercises as part of the GCP.<br /><h2>International initiatives</h2>India has spearheaded several international initiatives such as the International Solar Alliance (ISA), One World, One Sun, One Grid (OSOWOG), the Coalition for Disaster Resilient Infrastructure (CDRI), the Infrastructure for Resilient Island States’ (IRIS) and the Leadership Group for Industry Transition (LeadIT). Hundreds of nations are signed up for these climate coalitions and our participation will help reflect India's commitment to advancing global <keyword id="20000756" type="General" weightage="20" keywordseo="climate-action" source="keywords">climate action</keyword> and fostering international cooperation in sustainable development.<br /><div type="Article" hostid="261" msid="111923191" title="Economic Survey 2024 – industries grow by 9.5%, fueling economic growth to 8.2%" mstype="2" mssubtype="0"></div>The report even notes that India is currently the only G20 nation who is set not to cross the 2°C warming threshold. All in all, India’s economic survey and environmental reports together show a nation making impressive progress in combating climate change and advancing sustainability. These achievements will hopefully set a strong example for other countries to follow.<br />
