Researchers say Earth is expected to warm up to 4°C in the next 80 years

The UK’s Third Climate Change Risk Assessment (CCRA3) has been released and some information may have the world a little worried. According to the data, planet Earth can heat an average of 4°C to 2100.

As it turns out, all risks associated with global warming will increase in severity with a 2°C rise and even more with a 4°C rise that is expected in 80 years. The Technical Report concludes that global warming increases risks to the UK’s natural environment, human health, communities, infrastructure, business, security, migration and supply chains.

The projection is part of the UK’s Third Climate Change Risk Assessment (CCRA3) submitted to the UK Parliament. The report took two years of development, blending new research and a repertoire of many previous scientific works. It was also necessary to partner with the independent advice of the Climate Change Committee (CCC).

Although the forecast still has some (little) time, the data compiled for 2021 is no longer encouraging. Last year was the warmest year on record for the heat of the world’s oceans. The heat increase in 2021 alone compared to 2020 – about 14 zettajoules – is about 23 times more than the total energy used by everyone on Earth in 2019.

Speaking of the planet’s temperature in general, 2021 was the sixth warmest year on record according to data from NASA, NOAA (United States National Oceanic and Atmospheric Administration) and Berkeley Earth. By the Copernicus ERA5 data, it would be the fifth warmest year.

Additionally, 2021 was a year of many weather extremes around the world – including extreme heat events, heavy rains and floods, catastrophic fires, storms and droughts.

The next CCRA Climate Change Risk Assessment is already underway. And it is possible to check the CCRA3 report in full here.
