A related phenomenon driven by climate change is woody plant encroachment, affecting up to 500 million hectares globally. [218] Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [219] The size and speed of global warming is making abrupt changes in ecosystems more likely ...
As of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [14] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [15] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [16]
The more industrialized a country is, the more likely that it has contributed to climate change. States came to an agreement that developed countries contributed more to environmental degradation and should have greater responsibility for climate change mitigation than developing countries should.
Despite the fact that food is a big climate problem, very little has been done so far to address it. This year's U.N. climate conference in Dubai will be the first to dedicate a whole day to the ...

He wrote the 2017 essay "The Uninhabitable Earth"; the essay was published in New York as a long-form article and was the most-read article in the history of the magazine. [2] [3] Wells later expanded the article into a 2019 book of the same ...
The main benefit of a transition to low-carbon economies is that it would contribute towards climate change mitigation. Apart from that, other co-benefits can also be identified: Low-carbon economies present multiple benefits to ecosystem resilience, [ 11 ] trade, employment, health, energy security, and industrial competitiveness.
Drivers of climate change from 1850–1900 to 2010–2019. Future global warming potential for long lived drivers like carbon dioxide emissions is not represented. The scientific community has been investigating the causes of climate change for decades.
