The dangers of climate change threaten half of the world’s population

In its summary to policy makers, the IPCC added that this vulnerability varies from region to region and even within regions, driven by varying levels of socio-economic development, inequality and unsustainable use of land and oceans.

Global emissions of carbon dioxide jumped in 2021, to levels close to those recorded during the period before the Corona pandemic, which caused global economic paralysis that led to a huge decrease in greenhouse gas emissions.

A study by the Global Carbon Project, a coalition of international scientists that studies global carbon “budgets”, showed that total global carbon dioxide emissions in 2021 would be just 0.8 percent lower than in 2019.

She added that emissions from coal use in 2021 will exceed the level they were before the pandemic, but will remain below the record level recorded in 2014.

As for emissions resulting from the use of natural gas, they will reach their highest level ever in 2021, according to the study.

Because of the Covid-19 pandemic, most countries of the world have imposed restrictions on movement and closed several areas of the economy based mainly on fossil fuels, which caused in 2020, a huge drop in total greenhouse gas emissions of 5.4 percent, according to “AFP”. .

In 2021, according to the study, the level of emissions is expected to rise by 4.9 percent, to reach less than 1 percent from the record level recorded in 2019.

As for the distribution of emissions in 2021 according to geographical regions, the study expected that China, the largest emitter in the world since 2007, would record about a quarter of emissions, a jump in its share to reach 31 percent, or nearly a third of what the entire world produces in emissions.
