ipcc: Emissions peak by 2025 key to avoid climate disaster: IPCC | India News


NEW DELHI: Average annual global greenhouse gas emissions reached their highest levels in human history over the past decade (2010-19), the United Nations Intergovernmental Panel on Climate Change says (IPCC) in a report released Monday, noting that limiting global warming to 1.5 degrees Celsius – a prerequisite for saving the world from climate catastrophe – is out of reach. without “immediate and deep emissions reductions across all sectors” through phasing out fossil fuels.
It said although emissions growth had slowed over the past decade, limiting warming to around 1.5 degrees Celsius was the global requirement. GHG Emissions peak no later than 2025 and fall by 43% by 2030.
The latest IPCC report warns that if global greenhouse gas emissions do not peak by 2025 and fall by 43% over the next five years, the world will face a warming of about 3 degrees Celsius by 2020. year 2100.
A warming of 3 degrees by 2100 will have disastrous consequences such as longer-lasting heat waves, wildfires, sea level rise, melting glaciers, droughts and tornadoes. The average global temperature has increased 1.1 degrees Celsius above pre-industrial levels (1850-1900).
The report’s findings, prepared by 278 authors from 65 countries including India, are also a clear reflection of inadequate efforts in practice to cut emissions. It made United Nations secretary general Antonio Guterres calls it an “embarrassed file, listing empty pledges to keep us on our way to an unlivable world”.
“This IPCC report is a promise of broken climate promises, noting that the world is already “on a rapid track towards climate catastrophe,” said Mr. Guterres.
His anxiety is reflected in the report that anthropogenic GHG emissions reached 59 GtCO2eq in 2019, 54% higher than in 1990, mainly due to fossil fuels and industry. About 34% of human emissions come from the energy sector, 24% from industry, 22% from agriculture, forestry and land use, 14% from transport and 6% from buildings.
However, the report talks about the possibility of limiting global warming to around 1.5 degrees Celsius. As a glimmer of hope, it talks about the availability of many different options and tools, including including carbon dioxide removal (CDR) technology, which could lead countries to the goal of being net-free by 2050.
Providing an insight into how the world can limit warming to 1.5 degrees Celsius, it emphasizes deep emissions cuts by avoiding coal and phasing out fuel infrastructure. fossil.
