Ecosystems that store the most CO2 — especially tropical and boreal forests — could lose more than 45 percent of their capacity as carbon sponges by mid-century
This is despite an unprecedented fall in greenhouse gas emissions in 2020 because of the pandemic.
According to Climate Action Tracker, 49 states that had submitted their new proposals only represent 23.7 percent of global GHG emissions.
Peatlands keep a lot of carbon out of Earth's atmosphere, but that could end with warming and development
Although they only occupy three percent of the global land area, peatlands contain about 25 percent of global soil carbon — twice as much as the world’s forests.
China also pledged to reach its peak carbon emissions by 2030, which researchers claim needs coal-fired power to start reducing almost immediately.
Natural drivers of global warming already set in motion by carbon pollution will take on their own momentum.
Making companies accountable for their impact on the planet is the first step in reducing emissions, the envoy said.
US pulls out of Paris Accord: Amid changing scenario, experts fear move may weaken fight against global warming
While experts opine that it is unlikely that other countries will follow suit, concerns remain that some nations might adopt a go-slow approach.
Nobel economics prize: Bob Wilson and Paul Milgrom's insights into auctions could drive down carbon emissions
A key insight of Wilson’s analysis is the need for bidders to avoid the “winner’s curse”.
Thirty million sq km of ecosystems world over is agricultural or pasture land that was once forest, grasslands and shrublands.
'If COVID-19 doesn't kill us, climate change will': At annual UN meet, world leaders warn of 'environmental Armageddon'
The postponement of the UN climate summit hasn't stopped countries, from slowly sinking island nations to parched African ones, from speaking out.
Even in the lower emissions scenario, the Greenland sheet would raise oceans by around three cm by 2100 — beyond what is already destined to melt due to the additional 1C of warming humans have caused in the industrial age.
Human activities emitted 42 billion tonnes of CO₂ in 2019 alone and the report shows a shortfall of about 15 billion tonnes between the commitments and pathways consistent to limit warming to below 2℃.
The researchers part of the study calculated a time history of ocean-atmosphere CO2 fluxes (or movement) from 1992 to 2018.
Warming over land alone – which covers just 30 percent of the surface – has been double the global average, compared to pre-industrial levels.
COVID-19 is almost certain to have originated in animals before passing to and spreading among humans.
In the high atmosphere above Antarctica, carbon dioxide and other greenhouse gases do not have the warming effect they do in the lower atmosphere
Researchers explain why relaxed efforts against carbon emissions will not avoid substantial warming.
Countries need to work together to remove carbon dioxide from the atmosphere in order to avoid climate change
A system needs to be devised where quotas are fairly allocated and countries that cannot fulfil their obligations allowed to trade with those who can remove CO2.
Carbon emissions amid Covid-19 pandemic fell 17 percent globally, even higher in some countries: Study
The researchers predict that this 'extreme' effect of the Covid-19 global lockdown on daily emissions of carbon won't last.
