Many climate change impacts are already felt at the current 1.2 °C (2.2 °F) level of warming. Additional warming will increase these impacts and can trigger tipping points, such as the melting of the Greenland ice sheet. Under the 2015 Paris Agreement, nations collectively agreed to keep warming "well under 2 °C".However, with pledges made under the Agreement, global warming would still

Climate change caused by the emission of greenhouse gases from human activities affects global temperature and precipitation.Records from the Intergovernmental Panel on Climate Change indicate that the global average temperature has increased by at least 0.4 degrees Celsius (0.72 degrees Fahrenheit) since the 1970s, and that by 2100, it could increase to around 4 degrees Celsius (7.2 degrees
Responding to climate change involves two possible approaches: reducing and stabilizing the levels of heat-trapping greenhouse gases in the atmosphere ("mitigation") and adapting to the climate change already in the pipeline ("adaptation"). NASA's role is to make climate data available to the global community, including the public
The Rainforest Alliance breaks down the numbers for you—and explains our innovative approach to keeping forests standing. Among the many gifts forests give us is one we desperately need: help with slowing climate change. Trees capture greenhouse gases (GHGs) like carbon dioxide, preventing them from accumulating in the atmosphere and warming
