Emissions attributed to specific power stations around the world, color-coded by type of fuel used at the station. Lower half focuses on Europe and Asia [1]. This article is a list of locations and entities by greenhouse gas emissions, i.e. the greenhouse gas emissions from companies, activities, and countries on Earth which cause climate change.
For example, following the United States withdrawal from the Paris Agreement a coalition of cities, under the banner of Mayors National Climate Action Agenda. A 2020 study of US cities found that 45 of the 100 largest cities in the U.S. had made commitments by 2017, which led to a reduction of 6% of U.S. emissions by 2020.
As reported by the Intergovernmental Panel on Climate Change (IPCC), most of the observed global warming since the mid-20th century is very likely due to human-produced emission of greenhouse gases and this warming will continue unabated if present anthropogenic emissions continue or, worse, expand without control.
This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide, [275] for which transport is the fastest-growing emission sector. [276] By subsector, road transport is the largest contributor to global warming. [275]
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 ...
Global air temperatures have recently stopped rising proportionately to the increase in greenhouse gases in our atmosphere. But where is the heat going? A new NASA study from the Jet Propulsion ...
[2] [7] Tipping points are possible at today's global warming of just over 1 °C (1.8 °F) above preindustrial times, and highly probable above 2 °C (3.6 °F) of global warming. [5] It is possible that some tipping points are close to being crossed or have already been crossed, like those of the West Antarctic and Greenland ice sheets , the ...
Paleoclimate evidence shows the entire circulation has significantly weakened or completely collapsed in the past; preliminary research says such a collapse may become likely once global warming reaches between 1.7 °C (3.1 °F) and 3 °C (5.4 °F), but this estimate is much-less certain than for the majority of tipping points in the climate ...
