Updated 2022 estimates show that even at a global average increase of 1.5 °C (2.7 °F) over pre-industrial temperatures, only 0.2% of the world's coral reefs would still be able to withstand marine heatwaves, as opposed to 84% being able to do so now, with the figure dropping to 0% by 2 °C (3.6 °F) and beyond.
A high pressure system in the upper atmosphere traps heat near the ground, forming a heat wave (for North America in this example). A heat wave or heatwave, sometimes described as extreme heat, is a period of abnormally hot weather [1]: 2911 generally considered to be at least five consecutive days.
[1] [2] [3] Extreme events are based on a location's recorded weather history. They are defined as lying in the most unusual ten percent (10th or 90th percentile of a probability density function). [2] The main types of extreme weather include heat waves, cold waves and heavy precipitation or storm events, such as tropical cyclones.
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. [41] [42]
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 ...
There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding.

World map showing several marine heatwaves at different locations in August and September 2023. The marine heatwave west of South America is a prominent example. A marine heatwave is a period of abnormally high sea surface temperatures compared to the typical temperatures in the past for a particular season and region. [ 1 ]
This had the effect of poisoning water both for human and animal use. Additionally, nuclear power plants in Europe were having issues, because the water in the rivers used for cooling the reactors was too warm. This had the effect of electricity grids crashing in areas on four continents. The impacts were severe, even in some countries that are ...
