Species worldwide are migrating poleward to colder areas. Recent warming has strongly affected natural biological systems. Д¬limate change has degraded land by raising temperatures, drying soils and increasing wildfire risk. The uptake of carbon dioxide from the atmosphere is leading to ocean acidification. Even if global surface temperature is stabilized, sea levels will continue to rise and the ocean will continue to absorb excess heat from the atmosphere for many centuries. Since 1970, the ocean has absorbed more than 90% of the excess heat in the climate system.

Physical changes include extreme weather, glacier retreat, sea level rise, declines in Arctic sea ice, and changes in the timing of seasonal events (such as earlier spring flowering). There are three major ways in which global warming will make changes to regional climate: melting ice, changing the hydrological cycle (of evaporation and precipitation) and changing currents in the oceans. In particular, land areas change more quickly than oceans, and northern high latitudes change more quickly than the tropics. The changes in climate are not expected to be uniform across the Earth. Effects that scientists predicted in the past-loss of sea ice, accelerated sea level rise and longer, more intense heat waves-are now occurring. The future impact of climate change depends on how much nations reduce greenhouse gas emissions and adapt to climate change. The effects of climate change span the impacts on physical environment, ecosystems and human societies due to ongoing human-caused climate change. Some effects act as feedbacks that intensify climate change. The primary causes and the wide-ranging impacts of global warming and climate change.
