Scientists create mineral to absorb CO2 from atmosphere

Scientists have found a rapid way of creating magnesite, a mineral that can absorb carbon dioxide from the atmosphere, offering a potential solution to global warming. The research, presented recently at the Goldschmidt geochemistry conference in Boston, explained how magnesite can form at low temperatures and offered a way to …

To meet India’s massive 175 GW renewable target, govt has this solution to solve one big problem

India has an ambitious goal of installing 175 gigawatts of renewable energy by 2022, or a little more than the country’s current peak demand, as part of its Paris climate pledge to cut carbon emissions. India will test a plan to operate its underutilized natural gas-fired power generators as “peaker” …

Scientists trace atmospheric rise in CO2 during deglaciation to deep Pacific Ocean

Long before humans started injecting carbon dioxide into the atmosphere by burning fossil fuels like oil, gas, and coal, the level of atmospheric CO2 rose significantly as the Earth came out of its last ice age. Many scientists have long suspected that the source of that carbon was from the …

Brazil cuts deforestation emissions below 2020 targets

Brazil cut its greenhouse gas emissions from deforestation in 2017 to levels below its internationally agreed 2020 climate change targets, the country’s Environment Ministry said on Thursday. Brazil reduced its emission from deforestation in the Amazon rainforest by 610 million tonnes of carbon dioxide (CO2), compared to its 2020 target …

Ahmedabad: Greenery to curb greenhouse gases

AHMEDABAD: Trees have long served as the critical carbon sink, consuming carbon dioxide pollution produced by humans. They even clean up air by reducing particulate matter pollution (PM10, PM2.5). But our unending hunger for vehicles, depreciating green spaces owing to developmental activities, accentuates the release of carbon dioxide into the …

China restarts coal plant construction after two-year freeze

Satellite imagery reveals that many coal-fired power projects that were halted by the Chinese government have quietly restarted. Analysis by CoalSwarm estimates that 46.7 gigawatts of new and restarted coal-fired power construction is visible based on satellite imagery supplied by Planet Labs. The coal-fired power plants are either generating power …

Forests Crucial for Limiting Climate Change to 1.5 Degrees

Trying to tackle climate change by replacing forests with crops for bioenergy power stations that capture carbon dioxide (CO2) could instead increase the amount of CO2 in the atmosphere, scientists say. Biomass Energy with Carbon Capture and Storage (BECCS) power stations are designed to produce energy and store the resulting …

Report confirms 2017 was third warmest year

It's official! 2017 was the third-warmest year on record for the planet, just after 2016 and 2015, scientists have confirmed. According to the 28th annual State of the Climate report, the planet also experienced record-high greenhouse gas concentrations as well as rises in sea level. The report, published by the …

Lessons for Delhi: How China cut PM2.5 emissions by 33% in 5 yrs

NEW DELHI: A new Lancet study on the impact of China’s Air Pollution Prevention and Control Action Plan (2013-2017) could be a document of interest to a city like Delhi that is struggling to fight pollution. The study The study by Peking University School of Public Health found that annual …

Villagers 'living between life and death' as Pakistan's glaciers melt

When a glacial lake burst in Pakistan's northern Gilgit-Baltistan province in July, Sher Baz watched helplessly as the waters swept away his family home. Residents of Badswat village, which lies in Ishkoman valley at the foot of the Hindu Kush mountain range's snow-capped peaks, were at the mercy of the …

Warmer soil releasing more carbon, worsening climate change

Proper soil conservation techniques such as avoiding plowing and leaving crop residue on the ground can help keep more of the carbon in the soil. Even the dirt on the ground is making climate change worse, a new study finds. Plants capture massive amounts of carbon, pumping it into the …

Record-high greenhouse gas emissions in 2017: Report

Greenhouse gas emissions climbed to all-time highs in 2017, a year in which climate change caused scorching temperatures worldwide and ice to melt at record levels in the Arctic, according to a report. The report, “State of the Climate in 2017”, led by the US government’s National Oceanic and Atmospheric …

Last year was warmest ever that didn't feature an El Niño, report finds

Last year was the warmest ever recorded on Earth that didn’t feature an El Niño, a periodic climatic event that warms the Pacific Ocean, according to the annual state of the climate report by 500 climate scientists from around the world, overseen by the National Oceanic and Atmospheric Administration (Noaa) …

2017 UK's fifth warmest year on record, says Met Office

Last year was the fifth warmest on record for the UK, showing a clear warming trend above the long-term average, despite a wet summer last year and cold winter. The average temperature over the past decade, since 2008, was 0.8C above the 30 year average to 1990. Summers over that …

EU energy chief pushes for tougher emissions targets

The EU’s energy chief is pushing for member states to formally adopt a new set of carbon reduction target ahead of UN climate talks later this year. The EU already has some of the most ambitious carbon emission reduction targets in the world but Miguel Arias Cañete, the EU energy …

Environment report has bad news for Pune: In six years, greenhouse gas emissions increase by 29 per cent

The city generates 2,100 tonnes of solid waste every day, of which 1,078 tonnes is processed, and there are plans to set up seven plants to process the remaining amount. The Pune Municipal Corporation’s (PMC’s) efforts to reduce the emission of carbon may not have yielded much result, as a …

Patterns of longer-term climate change effects on CO2 efflux from biocrusted soils differ from those observed in the short term

Biological soil crusts (biocrusts) are predicted to be sensitive to the increased temperature and altered precipitation associated with climate change. We assessed the effects of these factors on soil carbon dioxide (CO2) balance in biocrusted soils using a sequence of manipulations over a 9-year period. We warmed biocrusted soils by …
