Climate change. Changes in surface air temperature over the past 50 years. [ 1] The Arctic has warmed the most, and temperatures on land have generally increased more than sea surface temperatures. Earth's average surface air temperature has increased almost 1.5 °C (about 2.5 °F) since the Industrial Revolution.
The list of climate change controversies (or list of global warming controversies) concerns past or present public debates over certain aspects of climate change: whether it is occurring ( climate change deniers dispute this), how much has occurred in modern times, what has caused it, what its effects will be, whether action should be taken to ...
Deforestation and climate change. Deforestation in the tropics – given as the annual average between 2010 and 2014 – was responsible for 2.6 billion tonnes of CO 2 per year. That was 6.5% of global CO 2 emissions. Deforestation is a primary contributor to climate change, [ 1][ 2] and climate change affects the health of forests. [ 3]
Main sources of global methane emissions (2008-2017) according to the Global Carbon Project [ 40] Methane emissions come from livestock, manure, rice cultivation, landfills, wastewater, and coal mining, as well as oil and gas extraction. [ 41] Nitrous oxide emissions largely come from the microbial decomposition of fertiliser.
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 warming trend, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires ...
A shift of 1 or 100% (darker colours) indicates that the region has fully moved into a completely different biome zone type. [1] Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. [2] [3] Climate change represents long-term changes in temperature and average weather patterns.
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
Data from 2018 found that at 1.5 °C (2.7 °F), 2 °C (3.6 °F) and 3.2 °C (5.8 °F) of global warming, over half of climatically determined geographic range would be lost by 8%, 16%, and 44% of plant species. This corresponds to more than 20% likelihood of extinction over the next 10–100 years under the IUCN criteria.
