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.

This USGS video is a form of science diplomacy requested by the U.S. Department of State to educate policy-makers and citizens in Southeast Asia about the vital importance of the Mekong river and delta in maintaining food security and livelihoods in the region. The video also seeks to make policy-makers aware of the potential impacts of climate change on people and the environment of the Mekong delta.
Water in the Anthropocene is a 3-minute film charting the global impact of humans on the water cycle. Evidence is growing that our global footprint is now so significant we have driven Earth into a new geological epoch — the Anthropocene. Human activities such as damming and agriculture are changing the global water cycle in significant ways. The data visualization was commissioned by the Global Water Systems Project for a major international conference (Water in the Anthropocene, Bonn, Germany, 21-24 May, 2013).
Scientists studying lakes in northern and tropical latitudes are finding that rising lake water temperatures are affecting the ecosystems of the lakes.
To achieve food security in a changing climate, the global community must operate within three limits: the quantity of food that can be produced under a given climate; the quantity needed by a growing and changing population; and the effect of food production on the climate.
Warmer global temperatures and higher levels of precipitation are generally good for plant productivity, but as temperatures have continued to rise, the benefits to plants are now overwhelmed by longer and more frequent droughts.
Black carbon, composed of tiny particles of soot, is produced whenever organic substances like fossil fuels, firewood or coal is incompletely burned. These particles are polluting the air and causing serious health and environmental concerns for people around the world.
Dr. Camille Parmesan, Associate Professor in the Section of Integrated Biology at the University of Texas, discusses her research. Parmesan's work has been on current impacts of climate change in the 20th century on wildlife. Her work on butterfly range shifts has been highlighted in many scientific and popular press reports, such as in Science, Science News, New York Times, London Times, National Public Radio, and the recent BBC film series "State of the Planet" with David Attenborough.
This video discusses the impacts of climate change on biodiversity on earth.
