Wind and solar photovoltaic account for the majority of renewables electricity capacity added each year. Renewable power is transforming the global electricity system, with new capacity and investment values consistently outstripping performance in the fossil-fuel sector. In 2016, more than 160 gigawatts of solar, wind, hydropower, geothermal, and biomass capacity was built around the world...Continue Reading
Heads of state and other leaders affirmed their commitments to fight climate change at the One Planet Summit in Paris on December 12, on the two-year anniversary of the Paris Agreement. Their calls for concrete action came as concentrations of the greenhouse gas carbon dioxide reached their highest level in 800,000 years. CO2 emissions rose 60% between 1990...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
