Oct 19, 2023 · The greenhouse effect happens when certain gases—known as greenhouse gases —collect in Earth’s atmosphere. These gases, which occur naturally in the atmosphere, include carbon dioxide , methane , nitrogen oxide, and fluorinated gases sometimes known as chlorofluorocarbons (CFCs).
Aug 21, 2024 · The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth’s atmosphere. Greenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated gases.

Climate change is altering temperature, precipitation, and sea levels, and will adversely impact human and natural systems, including water resources, human settlements and health, ecosystems, and biodiversity. The unprecedented acceleration of climate change over the last 50 years and the increasing confidence in global climate models add to the c...
Physical Systems
1. Global average temperatures in 2022 were 0.86°C (1.55°F) higher than the 20th century average.16 2. The warmest year on record since records began in 1880 was 2016, with 2020 ranking second. In 2020 global average land temperatures experienced a record high, while 2016 global ocean temperatures remain the highest on record.17 The nine warmest years on record since 1880 have all occurred within the last nine years (2014-2022), and in 2022 annual global temperatures were above average for th...
Biological Systems
1. Warming that has already occurred is affecting the biological timing (phenology) and geographic range of plant and animal communities.22 2. Often biological responses are not sufficient to handle the rapid spatial and temporal shifts that climate change is causing. Globally, approximately half of the species assessed have shifted polewards or to higher elevations.14 3. Relationships such as predator-prey interactions are affected by these shifts, especially when changes occur unevenly betw...
Increased Temperature
1. IPCC predicts global temperature will rise by 1.5°C (2.7°F) by the early 2030s.10 In the long term, global mean surface temperatures are predicted to rise 0.4-2.6°C (0.7-4.7°F) from 2045-2065 and 0.3-4.8°C (0.5-8.6°F) from 2081- 2100, relative to the reference period of 1986-2005. Since 1970, global average temperatures have been rising at a rate of 1.7°C per century, significantly higher than the average rate of decline of 0.01°C over the past 7,000 years.5,25
Ocean Impacts
1. Models anticipate sea level rise between 26 and 77 cm for a 1.5°C increase in temperature by 2100. The rise is a result of thermal expansion from warming oceans and water added to the oceans by melting glaciers and ice sheets.25 2. The oceans absorb about 31% of anthropogenic CO2 emissions, resulting in increased acidity. Coral reefs are projected to decline by 70–90% under a 1.5°C global warming senario.14,26
This century, an unprecedented combination of climate change, associated disturbances, and other global change drivers will likely exceed many ecosystems’ capacities for resilience.27 Risks associa...In 2023, the IPCC stated with very high confidence that “There is a rapidly closing window of opportunity to secure a livable and sustainable future for all.”14With an increase in average global temperatures of 2°C, nearly every summer would be warmer than the hottest 5% of recent summers.28Increased temperatures, changes in precipitation, and climate variability have increased the occurrence of food-borne and water-borne diseases. Vector-borne diseases are also occurring more often a...Jul 27, 2024 · greenhouse effect, a warming of Earth ’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.
