James Hansen, professor of Earth and Environmental Sciences at Columbia University, former NASA scientist, and the planet’s preeminent climatologist, was among the first to sound the alarm on climate change during his 1988 testimony before Congress. Since then, he has continued to shine a light on the problem through lectures, interviews, TED talks, and his...Continue Reading

Climate action: At the Summit, EU and Chinese leaders reaffirmed their commitment to implementing the 2015 Paris Agreement on climate change and, as major energy consumers and importers, highlighted the importance of fostering cooperation in their energy policies. At the joint press conference following the Summit, President of the European Commission Jean-Claude Juncker said: “As...Continue Reading

Greenland is the biggest island in the world. If we put all the ice in Greenland into the ocean, the global sea level would rise by 6 metres, which would put the majority of the world’s coastal cities under water. With a temperature increase of 2°C by 2100, 130 million people would be affected by...Continue Reading

The global community has made remarkable progress in driving down the costs and increasing the use of key clean energy options. However, these impressive gains are still insufficient to meet our long-term climate goals while providing affordable, reliable, and secure energy supplies. source: mission innovationContinue Reading

This graph shows how the average surface temperature of the world’s oceans has changed since 1880. This graph uses the 1971 to 2000 average as a baseline for depicting change. Choosing a di erent baseline period would not change the shape of the data over time. The shaded band shows the range of uncertainty in...Continue Reading

This gure shows concentrations of carbon dioxide in the atmosphere from hundreds of thousands of years ago through 2015, measured in parts per million (ppm). The data come from a variety of historical ice core studies and recent air monitoring sites around the world. Each line represents a di erent data source. Data source: Compilation...Continue Reading

This gure shows worldwide emissions of carbon dioxide, methane, nitrous oxide, and several uorinated gases from 1990 to 2010. For consistency, emissions are expressed in million metric tons of carbon dioxide equivalents. These totals include emissions and sinks due to land-use change and forestry.   Data sources: WRI, 2014; FAO, 2014 * HFCs are hydrofluorocarbons,...Continue Reading

This gure shows greenhouse gas emissions (positive values) and sinks (negative values), by source, in the United States from 1990 to 2014. For consistency, emissions are expressed in million metric tons of carbon dioxide equivalents. All electric power emissions are grouped together in the “Electricity generation” sector, so other sectors such as “Residential” and “Commercial”...Continue Reading
