In Brief:

The effects of human-caused global warming are happening now, are irreversible on the timescale of people alive sầu today, & will worsen in the decades khổng lồ come.


Global giamcanherbalthin.com change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have sầu shifted & trees are flowering sooner.

Effects that scientists had predicted in the past would result from global giamcanherbalthin.com change are now occurring: loss of sea ice, accelerated sea cấp độ rise & longer, more intense heat waves.

Taken as a whole, the range of published evidence indicates that the net damage costs of giamcanherbalthin.com change are likely to be significant và khổng lồ increase over time.

Scientists have sầu high confidence that global temperatures will continue to rise for decades lớn come, largely due lớn greenhouse gases produced by human activities. The Intergovernmental Panel on giamcanherbalthin.com Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 lớn 10 degrees Fahrenheit over the next century.

According khổng lồ the IPCC, the extent of giamcanherbalthin.com change effects on individual regions will vary over time và with the ability of different societal & environmental systems to mitigate or adapt to change.

The IPCC predicts that increases in global mean temperature of less than 1.8 lớn 5.4 degrees Fahrenheit (1 lớn 3 degrees Celsius) above sầu 1990 levels will produce beneficial impacts in some regions and harmful ones in others. Net annual costs will increase over time as global temperatures increase.
