A 2018 study examined the impact of climate change on Troglohyphantes cave spiders in the Alps and found that even the low-emission scenario RCP2.6 would reduce their habitat by ~45% by 2050, while the high emission scenario would reduce it by ~55% by 2050 and ~70% by 2070. The authors suggested that this may be sufficient to drive the most ...
[2] [3] Climate change represents long-term changes in temperature and average weather patterns. [4] [5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6] As a region's climate changes, a change in its flora and fauna follows. [7]
Biodiversity loss is occurring on a global scale and humans are driving this through changes in land use, exploitation of organisms, climate change, pollution, and invasive species. [10] According to WWF's Living Planet Report, these drivers are underpinned by rapid economic growth and human population growth over the past 50 years. [11]
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 ...
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [48] as well as in the 2024 UNEP Actions on Air Quality report. [49]
Overall, the effects of climate change increase stress on ecosystems, and species unable to cope with the rapidly changing conditions will go extinct. [28] While modern climate change is caused by humans, past climate change events occurred naturally and have led to extinctions.
These tend to be directly or indirectly connected to climate change and can cause a deterioration of forest ecosystems. [37] [38] Groups that care about the environment have been working for many years to stop the decrease in biodiversity. Nowadays, many global policies include activities to stop biodiversity loss.
A study quantified climate change mitigation potentials of 'high-income' nations shifting diets – away from meat-consumption – and restoration of the spared land, finding that if these were combined they could "reduce annual agricultural production emissions of high-income nations' diets by 61%".
