Climate change is happening. These real, observable changes are what we call climate change impacts because they are the visible ways that climate change is affecting the Earth. For example, many places have experienced changes in rainfall, more frequent natural disasters such as more severe droughts in many regions. Deserts are expanding reducing land for growing food, while heat waves and wildfires are becoming more common.
The planet’s oceans and glaciers have also experienced changes — oceans are warming and the increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss cause sea levels to rise, threatening coastal and island communities.
Species
Risk of species losses
As per IPCC Report 30,652 species of birds, mammals, reptiles, amphibians, marine, fish, corals, seagrass are under threat at 4 degree rise in temperature.
Species on the brink of extinction
10,967 species are facing immediate likelihood of their extinction as per the International Union for Conservation of Nature.
Oceans
Coral reefs
Coral reefs
At 1.5°C warming 70-90% of the world's Coral reefs are projected to die.
Marine heatwaves
Marine heatwaves
The heatwaves has become at least,34% more frequent and 17% longer since 1925.
Natural Systems
Land Systems
Terrestrial Heat Waves now regularly occurring that exceed the physiological thresholds of species, that can cause mass mortality events due to hyperthermia (increase in body temperature) and dehydration, of all land creatures including human being.
Water Ecosystem
Heating of the water and increase in absorption of CO2 lead to abnormally high-water temperatures, decrease in oxygen levels and acidification of water increasing the mortality rate of life existing in water ecosystems.
Forests
Severe drought
Severe drought
At 2°C of warming, severe drought in Brazil's natural areas is expected to quadruple.
Wildfire
Wildfire in the Arctic tundra
Burning across Siberia has increased ninefold from 1996 to 2015.
Rainforest
Rainforest
At high emissions, Drought and Wildfire could transform half of the Amazon basin into
grassland leading to increased global emissions.
