Climate Change - NASA Science (original) (raw)

What are the effects of climate change?

The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.

We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.
