Thus effects of elevated CO 2 on plant growth will vary with local climate patterns, species adaptations to water limitations, and nitrogen availability. Studies indicate that nutrient depletion may happen faster in drier regions, and with factors like plant community composition and grazing.
The strongest effects were seen in the southern regions, where rapid increases in frequency of extreme warm years had exceeded the species’ historical temperature ranges. [72] [73] In 2024, a major review paper projected likely extinctions of 14% to 27% insects under RCP4.5 by the year 2070, and 23% to 31% under RCP8.5. [46]
Other observed effects also include the lengthening in growing seasons of certain agricultural crops such as wheat and maize. [33] A recently published study has used data recorded by the writer and naturalist Henry David Thoreau to confirm effects of climate change on the phenology of some species in the area of Concord, Massachusetts.

The green, orange and yellow lines indicate how surface temperatures will likely respond if leading carbon emitters begin to reduce reliance on fossil fuels. Without immediate curbs, temperatures are set to follow the red track, and increase between 3.2 and 5.4 degrees Celsius by 2100. The green line shows how we can minimize warming if ...
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 ...
Climate change has raised the temperature of the Earth by about 1.1 °C (2.0 °F) since the Industrial Revolution.As the extent of future greenhouse gas emissions and mitigation actions determines the climate change scenario taken, warming may increase from present levels by less than 0.4 °C (0.72 °F) with rapid and comprehensive mitigation (the 1.5 °C (2.7 °F) Paris Agreement goal) to ...
Extreme weather events affect public health, and food and water security. [239] [240] [241] Temperature extremes lead to increased illness and death. [239] [240] Climate change increases the intensity and frequency of extreme weather events. [240] [241] It can affect transmission of infectious diseases, such as dengue fever and malaria.
Increased temperatures and changes in precipitation patterns can reduce forest growth rates and change species composition, potentially diminishing the forests' capacity to sequester carbon. Extreme weather events, such as droughts and storms, can lead to increased tree mortality, further reducing the carbon storage capacity of these forests ...
