Climate change is felt in every region of the world, warns the Intergovernmental Panel on Climate Change (IPCC).
A newly published study by the UN agency evaluating science in relation to climate change found that many of these changes are “unprecedented in thousands, if not hundreds of thousands of years” – and that some are “irreversible over hundreds to thousands of years” are years “.
The 234 scientists behind the research calculate that global temperature is likely to rise by 1.5 ° C over the next 20 years, in violation of the 2015 Paris Agreement. A total of 195 nations agreed on the goal of “keeping the rise in the global average temperature well below 2 ° C” and making efforts to “limit the temperature rise to 1.5 ° C above the pre-industrial level”, according to the IPCC.
Scientists typically measure rising global temperatures at the baseline of the years between about 1850 and 1900 (defined as the “pre-industrial period”), “when fossil fuel burning had yet to change the climate,” reports the BBC.
Greenhouse gas emissions from human activities have been responsible for around 1.1 ° C of warming since that time, according to the newly published study, which “was in the works for eight years,” says The Guardian. The IPCC found that human activity is “clearly” the cause of rapid climate change, including sea level rise, melting of polar ice and glaciers, heat waves, floods and droughts.
The damning report, however, is not without hope. The experts say that “strong and sustainable reductions” in emissions of greenhouse gases, including carbon dioxide, would be able to limit climate change.
But “while the air quality benefits would be felt quickly, it could take 20 to 30 years for global temperatures to stabilize,” added the UN panel.
The co-chair of the IPCC working group, Valerie Masson-Delmotte, described the results as a “reality check”, while UN Secretary-General Antonio Guterres described the report as the “Code Red for Humanity”.
As environmental groups urge governments to act immediately, WWF’s chief advisor on climate change, Dr. Stephen Cornelius added that the report is “a keen assessment of the frightening future that awaits us if we do not act”.
Boris Johnson described the report as a “sobering” read.
“We know what needs to be done to limit global warming – hand coal to history and switch to clean energy sources, protect nature and provide frontline countries with climate finance,” said a statement from the prime minister who Criticized last week for the joke that Margaret Thatcher’s bulk coal mine shutdown in the 1980s was good for climate change.
The new study results will be published less than three months before the 2021 United Nations Climate Change Conference, also known as Cop26, in Glasgow. Much of the conference will focus on achieving the goals set in the 2015 Paris Agreement and advancing the UN climate change process.
The summary of the IPCC report “will provide a basis for negotiations at the November World Summit,” reports the Financial Times.
