Heat waves are abnormally hot weather that occurs over a few days to several weeks, and climate change is making them worse. Watch and find out why heat waves are a hazard and what you can do to stay safe when they happen.
In the past century, as the climate has warmed, sea level rise has accelerated. Scientists predict it will only increase, and they're studying changes in the ocean and land to better understand how and why the water is rising.
You may know that melting glaciers and ice sheets is causing sea levels to rise. Did you also know that the ocean absorbs heat, causing it to expand? Learn more about this process and how it’s impacting coastlines around the planet.
