New York, April 4 / BNA / The world’s highest body of climate scientists said today, Monday, that Earth’s temperatures will exceed the main danger point unless greenhouse gas emissions fall faster than countries committed to, warning of the consequences of not taking any action, but indicated Also to signs of hopeful progress.
UN Secretary-General Antonio Guterres said the report from the Intergovernmental Panel on Climate Change revealed a “chain of breaching climate promises” by governments and companies, accusing them of fueling global warming by clinging to harmful fossil fuels.
“It’s a shameful dossier, cataloging the empty pledges that put us firmly on the right track toward an unlivable world,” he said.
Governments agreed in the 2015 Paris Agreement to keep global warming well below 2 degrees Celsius (3.6 Fahrenheit) this century, ideally no more than 1.5 degrees Celsius (2.7 Fahrenheit).
However, temperatures have already risen by more than 1.1°C (2°F) since pre-industrial times, leading to measurable increases in disasters, endangering human lives and costing governments hundreds of billions of dollars to contend with.
“Projected global emissions from (national pledges) put global warming to 1.5°C out of reach and make it difficult after 2030 to limit warming to 2°C,” the panel said.
The report found that ongoing investments in fossil fuel infrastructure and deforestation for agriculture undermine the massive emissions constraints needed to achieve the Paris target.
Skia said emissions in 2019 were about 12% higher than they were in 2010 and 54% higher than they were in 1990.
The report’s authors said the growth rate slowed from 2.1% per year in the early part of this century to 1.3% per year between 2010 and 2019.
But they expressed “high confidence” that unless nations step up efforts to cut greenhouse gas emissions, the planet will, on average, be 2.4°C to 3.5°C (4.3 to 6.3°F) warmer by the end of the century – a level experts say It is sure to cause severe effects for much of the world’s population.
“Limiting temperature rise to 1.5 degrees Celsius requires that greenhouse gas emissions peak before 2025 at the latest and be reduced by 43% by 2030,” he said.
The committee acknowledged that it would be difficult to achieve such cuts without drastic measures at the level of the economy. The world is likely to exceed 1.5°C and efforts will then be needed to bring temperatures down again, including by removing massive amounts of carbon dioxide – a major greenhouse gas – from the atmosphere.
Many experts say this is not possible with current technologies, and even if it could be done it would be much more expensive than preventing emissions in the first place.
About 40% of emissions since then have come from Europe and North America, the UN panel said. Just over 12% can be attributed to East Asia, including China. The country took over the position as the world’s largest emitter from the United States in the mid-2000s.
