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. [11] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [12] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [13]
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...

The environmental effects of climate change are broad and far-reaching, affecting oceans, ice, and weather. Changes may occur gradually or rapidly. Changes may occur gradually or rapidly. Evidence for these effects comes from studying climate change in the past, from modelling, and from modern observations. [ 197 ]
