Only immediate, ambitious climate action will prevent global temperatures from rising by 1.5 C – a benchmark agreed in the 2015 Paris Agreement – the report said on Monday. Otherwise, there could be some extreme climate change with serious consequences for humans, wildlife and ecosystems. However, there are solutions that could make a difference, the report suggests. “Having the right policies, infrastructure and technology to make changes to our lifestyles and behaviors can reduce greenhouse gas emissions by 40-70 percent by 2050,” said Priyadarshi Shukla, co-chair of the IPCC Working Group. III, and a professor at the Ahmedabad Indian Institute of Management specializing in energy and environmental modeling and policies, said in a press release. “This offers significant untapped potential” for reducing the overall rise in global temperature.

Absorption of CO2 from the atmosphere

Global warming is caused by an excessive amount of carbon dioxide released into the atmosphere by human activities. Its abolition is important in the fight against climate change. Indeed, the IPCC report states that the removal of carbon dioxide is the key to limiting heating to 2 C or 1.5 C. This can be done through methods that include reforestation, ocean lubrication and “enhanced weather”. – the process of spreading crushed rock in large areas.

The UN report on the climate crisis presents a bleak picture

People are well on their way to overcoming a critical climate threshold unless significant efforts are made to reduce emissions and reduce dependence on fossil fuels, warns the latest UN report on climate change. In the 2015 Paris Agreement on Climate Change, the countries agreed to limit global warming to 1.5 C. 3:36
CO2 could also be removed through technology such as direct carbon capture (DACCS) that uses chemical processes to separate and store CO2. However, the effectiveness of DACCS has been and some critics say this CO2 removal may undermine incentives to switch to fossil fuels.

Sea salt in the clouds? Drawing aerosols in the sky?

The IPCC report also looked at proposals to increase the reflection of solar radiation back into space. He says modifying solar radiation (SRM) may not be the main policy response to climate change and is, at best, a complement to the broader goal of achieving consistently clean zero CO2 levels worldwide. Some suggested SRM methods include:

Injection of reflective aerosol particles, or aerosol-converted gas, directly into the stratosphere. Spraying sea salt or other particles in the sea clouds, making them more reflective. Roof whitening and glacier cover with reflective lining.

However, the IPCC states in its report that “their potential to reduce risk or introduce new risks… is not well understood”.

Switch to solar and wind energy as costs decrease

Switching to renewable energy could be much easier now, as unit costs for solar, wind and battery power have plummeted over the past four years, according to the report. For example, from 2015 to 2020, the cost of electricity generated by solar and wind energy fell by 56 percent and 45 percent, respectively, while battery prices fell by 64 percent, according to the report. Also, in many contexts, solar and wind energy are now in competition with fossil fuels, the report said.

Electric vehicles

Electric vehicles are the fastest growing segment of the automotive industry, according to the report, and, along with electric public transport vehicles, can significantly reduce emissions, the report said.

The rich can be helped by social influences as well

Although they are rich, they disproportionately contribute to higher emissions, they could also become low-carbon lifestyle models, investing in part in low-carbon companies and advocating for stricter climate policies, the report said. Social influences and thought leaders can also increase the adoption of low carbon technologies, behaviors and lifestyles, he said.
