Our changing climate

We see climate change affecting our planet from pole to pole. NOAA monitors global climate data and here are some of the changes NOAA has recorded.
You can explore more at the Global Climate Dashboard.

* Global temperatures rose about 1.8°F (1°C) from 1901 to 2020.
* Sea level rise has accelerated from 1.7 mm/year throughout most of the twentieth century to 3.2 mm/year since 1993.
* Glaciers are shrinking: average thickness of 30 well-studied glaciers has decreased more than 60 feet since 1980.
* The area covered by sea ice in the Arctic at the end of summer has shrunk by about 40% since 1979.
* The amount of carbon dioxide in the atmosphere has risen by 25% since 1958, and by about 40% since the Industrial Revolution.
* Snow is melting earlier compared to long-term averages.

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.
