NEW DELHI: Average annual global greenhouse gas emissions hit their highest levels in human history in the last decade (2010-19), said UN’s Intergovernmental Panel on Climate Change (IPCC) in its report released on Monday while noting that limiting global warming to 1.5 degree Celsius – a prerequisite to save the world from climate catastrophe – was beyond reach without “immediate and deep emissions reductions across all sectors” through phasing out fossil fuels.
It said though the rate of emission growth had slowed in the last decade, limiting warming to around 1.5 degree C requires global GHG emissions to peak before 2025 at the latest, and be reduced by 43% by 2030.
The IPCC’s latest report warns if global greenhouse gas emissions don’t peak by 2025 and reduce by 43% in the subsequent five years, the world will have to face warming of around 3 degree C by 2100.
A 3-degree warming by 2100 will have disastrous consequences such as longer heat waves days, forest fires, sea level rise, melting of glaciers, droughts and cyclones, it said. The global average temperature has already increased to 1.1 degree Celsius from pre-industrial (1850-1900) levels.
The findings of the report, prepared by 278 authors from 65 countries including India, are also a clear reflection of inadequate efforts on the ground to cut emissions. It prompted the UN secretary-general Antonio Guterres to call it a “file of shame, cataloguing the empty pledges that put us firmly on track towards an unliveable world”.
“This report of IPCC is a litany of broken climate promises,” said Guterres, noting that the world is already “on a fast track to climate disaster”.
His worry gets reflected in the report which shows that human-caused GHG emissions reached 59 GtCO2eq in 2019, 54% higher than in 1990, primarily driven by fossil fuels and industry. About 34% of human emissions came from the energy sector, 24% from industry, 22% from agriculture, forestry and land use, 14% from transport and 6% from buildings.
The report, however, spoke about the possibility of limiting global warming to around 1.5 degree C, provided the world moves towards major transitions in the energy sector. As a ray of hope, it spoke of the availability of multiple options and various tools, including carbon dioxide removal (CDR) technology, which can lead the nations to the global net-zero goal by 2050.
Giving an insight into how world can limit warming to 1.5 degree C, it emphasised on going for deep emission cuts by shunning coal use and phasing out fossil fuel infrastructure.
