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. [15] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [16] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [17]
The global average and combined land and ocean surface temperature show a warming of 1.09 °C (range: 0.95 to 1.20 °C) from 1850–1900 to 2011–2020, based on multiple independently produced datasets. [14] The trend is faster since the 1970s than in any other 50-year period over at least the last 2000 years. [14]
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 ...
Maritime nations agreed Friday to slash emissions from the shipping industry to net zero by about 2050 in a deal that several experts and nations say falls short of what's needed to curb warming ...
Children are physically more vulnerable to climate change in all its forms. [5] Climate change affects the physical health of children and their well-being. Prevailing inequalities, between and within countries, determine how climate change impacts children. [6] Children often have no voice in terms of global responses to climate change.
This is a list of statements by major scientific organizations about climate change, that have issued formal statements of opinion, classifies those organizations according to whether they concur with the IPCC view (i.e. the scientific consensus on climate change ), are non-committal, or dissent from it. The California Governor's Office website ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [35] [36] [37] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [34]
The stratified layers limit how much vertical water mixing takes place, reducing the exchange of heat, carbon, oxygen and particles between the upper ocean and the interior. [53] Since 1970, there has been an increase in stratification in the upper ocean due to global warming and, in some areas, salinity changes. [14]
