Climate change mitigation policies can have a large and complex impact on the socio-economic status of individuals and countries This can be both positive and negative. [300] It is important to design policies well and make them inclusive. Otherwise climate change mitigation measures can impose higher financial costs on poor households. [301]
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 ...
Many negative effects of climate change involve changes in extremes or the way conditions vary rather than changes in average conditions. [15] For example, the average sea level in a port might not be as important as the height of water during a storm surge.
As of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [14] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [15] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [16]
The Planck response is the additional thermal radiation objects emit as they get warmer. Whether Planck response is a climate change feedback depends on the context. In climate science the Planck response can be treated as an intrinsic part of warming that is separate from radiative feedbacks and carbon cycle feedbacks.
The effects of climate change vary in timing and location. Up until now the Arctic has warmed faster than most other regions due to climate change feedbacks. [165] Surface air temperatures over land have also increased at about twice the rate they do over the ocean, causing intense heat waves.
Another study, which checked the data from the last 120 years, found that climate change has already reduced welfare by 29% and further temperature rise will bring this number to 47%. The temperature rise during the years 1960-2019 alone has already cut current GDP per capita by 18%. A rise by 1 degree in global temperature reduces global GDP ...
The most common effect of climate change on dolphins is the increasing water temperatures across the globe. [131] This has caused a large variety of dolphin species to experience range shifts, in which the species move from their typical geographic region to cooler waters.
