The Global Groundwater Statement — A Call  to Action cites recent scientific breakthroughs that have highlighted the regional and international importance of the issue as well as global connections and threats to groundwater, which makes up 99 per cent of the Earth’s liquid freshwater.

Greenland is losing ice faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change’s high-end climate scenario.

Understanding what influences the amount of methane in the atmosphere has been identified by the American Geophysical Union to be one of the foremost challenges in the earth sciences in the coming decades because of methane’s hugely important role in meeting climate warming targets.

The identification of natural carbon sinks and understanding how they work is critical if humans are to mitigate global climate change. 

The increase in carbon dioxide concentration in the atmosphere has warmed the Earth since the beginning of the industrial era. 

The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts.

Cold cloud top temperatures can tell forecasters if a tropical cyclone has the potential to generate heavy rainfall, and that is exactly what NASA’s Aqua satellite found when it observed the temperatures in Tropical Cyclone Belna over northwestern Madagascar.

The actual amount of precipitation is generally underestimated in the case of snowfall. Meteorologists are working on methods that are already in use to measure precipitation more accurately.

Snowstorms can wreak havoc across the United States, but especially on the East Coast.

Discovery may inspire development of better industrial catalysts.
