Climate Change Report: 15 Key Findings from the 2021 UN Report

It is a “red code for humanity,” said UN Secretary-General Antonio Guterres (Photo: Getty / Reuters / AP).

The catastrophic effects of climate change are now “unavoidable” and The abominable report of the United Nations released today I warned.

It is “clear” that human activity is warming the planet and causing “unprecedented” changes in land, atmosphere and oceans, leading scientists warn in a groundbreaking 2021 study. ..

The long-awaited document references more than 14,000 scientific treatises and involves 234 authors from around the world.

“No one is safe and it’s getting worse rapidly,” said Inger Andersen, executive director of the United Nations Environment Program.

UN Secretary-General Antonio Guterres has called the situation a “red code for humanity” and is calling on countries to step up their efforts to reduce emissions over the last decade.

He states:

“Global heating is affecting every part of the globe, and many of the changes are irreversible. The internationally agreed threshold of 1.5C is dangerously close.

So what are the key findings from the alarming report? Join Metro.co.uk and take a look.

– It is “obvious” that human activity has warmed the atmosphere, sea and land, and is changing extensively and rapidly throughout the globe.

– Many results have been “unprecedented” for centuries to thousands of years, with the Earth warming at an unprecedented rate for at least 2,000 years.

– Atmospheric carbon dioxide levels have not been so high for 3 million years.

– Methane concentration is higher than it was 800,000 years ago.

– Both greenhouse gas rises far outweigh the natural changes seen over hundreds of thousands of years.

– Due to human activities such as burning fossil fuels and deforestation, average temperatures over the last decade have increased by about 1.1 ° C compared to before the Industrial Revolution.

– Strong evidence of climate change in all parts of the world, including more frequent or heavy heat waves, heavy rains, droughts, and tropical cyclones, and the role that humans play in driving change.

– Humans are very likely to be responsible for the global retreat of glaciers, the reduction of sea ice, the warming of the sea and the rise of sea levels. The rate of sea level rise is accelerating.

– The world’s surface temperature will continue to rise until at least the middle of the century, so the world will reach warming of over 1.5 ° C over the next 20 years.

– 1.5C and 2C global warming – Limits promised by countries to avoid the most dangerous effects of climate change – Significant reductions in carbon dioxide and other greenhouse gas emissions will not occur in the coming decades As long as it is beyond the 21st century.

– Continuous warming promotes extreme temperatures, ocean heat waves, heavy rains, droughts in some areas, an increase in the proportion of severe tropical cyclones, and a reduction in Arctic sea ice, snow cover, and permafrost. To do.

– With increasing warming, extreme changes will be greater, and with each increase in temperature of 0.5 ° C, the intensity of heat waves will increase significantly, causing heavy rains and droughts that can cause floods.

– In future scenarios of increasing carbon dioxide emissions, marine and terrestrial carbon sinks, such as forests, are projected to be less effective in delaying the accumulation of greenhouse gases in the atmosphere.

– Changes in melting of oceans, sea levels, and permafrost and glaciers as a result of past and future warming are irreversible for decades, centuries, and even thousands of years.

– Controls global warming and improves air quality by reducing methane emissions strongly, quickly and sustainably.
