NASA: IPCC Projections of Temperature and Precipitation in the 21st Century

Published on YouTube Sep 27, 2013: New data visualizations from the NASA Center for Climate Simulation and NASA’s Scientific Visualization Studio show how climate models — those used in the new report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) — estimate how temperature and precipitation patterns could change throughout the 21st century.…

IPCC Report AR5 September 2013 (WG1) “The Pause”

On September 27 2013 the IPCC released the WG1 report of the IPCC AR5 assessment. UN Secretary General Ban-Ki Moon addressed the IPCC at Stockholm on 27 September. He stated that “the heat is on. We must act”. US Secretary of State John Kerry responded to the report saying “This is yet another wakeup call: those who deny the science…

Meet the NASA computer used for most climate simulations

The actual computer we do all of our climate simulations on (well, a little bit of it). pic.twitter.com/Z1qSFlgJwm — Gavin Schmidt (@ClimateOfGavin) July 16, 2013 System Architecture The system architecture is made up of multiple scalable units. The list below describes the total aggregate components of the system and its individual scalable units. Aggregate 67…

Each degree of global warming might ultimately raise global sea levels by more than 2 meters

By PIK: 07/15/2013 – Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of…

A Mechanism for Shallow Methane Hydrate Dissociation

I previously looked at the science and commercial usage of Methane Hydrate, at freshwater influx in the Arctic Circle and asked  Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean? This post covers: Identification of possible mechanism which could eventually release vast quantities of shallow Methane Hydrate…

NASA: Wildfires, Smog – Particulate Matter Will Only Get Worse (August 2013)

August 10, 2013 – NASA Research is showing due to the increase in the earth’s temperature, we can expect to see more wildfires, and fires in areas that normally don’t see fires. NASA scientists talked to The Weather Channel about the latest research. http://www.nasa.gov/mission_pages/fires/main/index.html

NASA: Potential Evaporation in North America Through 2100 (August 2013 in HD)

Published on Aug 9, 2013 by NASA: This animation shows the projected increase in potential evaporation through the year 2100, relative to 1980, based on the combined results of multiple climate models. The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or…

NASA: The Future of Fires in Perspective to Future Emissions Scenario’s (August 2013)

Published on Aug 8, 2013 by NASA: With climate change, certain areas of the United States, like the great Plains and Upper Midwest, will be at a greater risk of burning by the end of the 21st-century. Areas like the Mountain West that are prone to burning now will see even more fires than they…

Population: Education Leads to Lower Fertility and Increased Prosperity

By Brigid Fitzgerald / Earth Policy Institute first published May 12, 2011. As the world continues to add close to 80 million people each year, high population growth is running up against the limits of our finite planet, threatening global economic and political stability. To stay within the bounds of the earth’s natural resources, the…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…
