The 936 PPM CO2 NASA Model Prediction

This NASA visualization is based on the latest IPCC report, and uses the business as usual scenario, where carbon dioxide concentrations rise to 936 parts per million—more than double today’s levels of 400 parts per million—by the year 2100. Temperature anomalies are estimated to be close to 4°C in the Arctic. https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11453

The Climate Spiral: Carbon budget, CO2 and Temperature since 1850

07/27/2016 – Global-mean temperatures are breaking one record after the other since instrumental observations began. Driven by burning of fossil fuels and deforestation, carbon dioxide concentrations have also soared to unprecedented levels. In fact, today’s CO2 concentrations are higher than they have ever been over the last 800 thousand years. Scientists from the Potsdam Institute…

Climate action

Climate action describes various efforts to prevent what is considered dangerous climate change. See also: Politics of global warming Agriculture See also: Climate change and agriculture According to the EPA, agricultural soil management practices can lead to production and emission of nitrous oxide (N2O), a major greenhouse gas and air pollutant. Activities that can contribute…

Arctic Sea Ice Reaches 2015 Minimum Extent

Arctic Sea Ice Summertime Minimum Is Fourth Lowest on Record According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado…

NASA Rising Seas: The State of the Greenland Ice Sheet (2015)

Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of…

Ice Core Secrets Could Reveal Answers to Global Warming

At the Stable Isotope Lab in Boulder, Colo., scientists are doing a lot of the same things that those CSI folks do on TV. But instead of being “crime scene investigators,” these experts are more like “cold scene investigators.” Geoscientists like lab director Jim White work primarily with one raw material : ancient ice, in…
