By March, Volvo Cars announced that by 2030 it "intends to only sell fully electric cars and phase out any car in its global portfolio with an internal combustion engine, including hybrids". [171] In April 2021, Honda announced that it will stop selling gas-powered vehicles by 2040. [ 172 ]
In Europe, the European Commission enforced that from 2015 all new cars registered shall not emit more than an average of 0.13 kg (0.29 lb) of CO 2 per kilometre (kg CO 2 /km). The target is that by 2021 the average emissions for all new cars is 0.095 kg (0.21 lb) of CO 2 per kilometre.
In a 2024 survey, 76.3% of responding IPCC lead authors and review editors projected at least 2.5 °C of global warming by 2100; only 5.79% forecast warming of 1.5 °C or less. [98] January: the World Economic Forum projected that, by 2050, directly and indirectly, climate change will cause 14.5 million deaths and $12.5 trillion in economic losses.
The 2016 agreement aimed to limit the increase in Earth's average global temperature to 1.5 degrees Celcius, or 2.7 degrees Fahrenheit, in an effort to avoid catastrophic effects from global warming.
5 May: a study published in Nature used an observationally calibrated ice sheet–shelf model to project that with 2 °C global warming, Antarctic ice loss will continue at its current pace; but that current policies would allow 3 °C warming and give an abrupt jump around 2060 to an order of magnitude increase in the rate of sea-level rise (to ...

Efforts to banish SO2 as a harmful air pollutant in China and elsewhere over the last decade have dampened its cooling effect and "unmasked" heat caused by greenhouse gases, thereby contributing ...
The idea of net zero came out of research in the late 2000s into how the atmosphere, oceans and carbon cycle were reacting to CO 2 emissions. This research found that global warming will only stop if CO 2 emissions are reduced to net zero. [18]
