Megacities Carbon Project: monitoring emissions from the world's largest cities

Video Friday: Los Angeles, Paris to Participate in Megacities Carbon Project

Cities are responsible for 70 percent of greenhouse gas emissions from fossil fuels. Los Angeles and Paris are both participating in the Megacities Carbon Project, a research study by NASA’s Jet Propulsion Laboratory to develop and test methods for more accurately measuring greenhouse gas emissions from cities and power plants. The stated goal of the project is to “demonstrate a…

US Needs to Be Better Prepared for Extreme Weather, Ecological Changes Resulting from Climate Change

Climate change will cause changes in plant communities across nearly half the Earth’s land surface by 2100, driving conversion of nearly 40 percent of land-based ecosystems from one major ecological community type – forest, grassland or tundra – toward another, according to a new computer study conducted by NASA’s Jet Propulsion Laboratory and the California Institute of Technology in Pasadena. The…

Accelerating ice melt from the Greenland and Antarctic ice sheets will significantly impact sea level rise in the coming decades

Melting Ice Sheets the Largest Contributor to Sea Level Rise

A new study to be published this month in the journal Geophysical Research Letters has found that the Greenland and Antarctic ice sheets are losing mass at an accelerating rate. The rapidly accelerating ice melt from the ice sheets is happening much sooner the models have predicted. According to the research, the ice sheets are now overtaking the ice loss…
