Here is an interesting NOAA video which shows the change in carbon dioxide over time on Earth for two spots, Mauna Loa and the South Pole. Then it goes back further in time using data from ice cores all the way back to 800,000 years ago. Be sure to watch all the way to the…

If you are interested in climate science and how climatologists view climate change, you might be interested in this video series called “Global Weirding” by Katharine Hayhoe of Texas Tech University. In the series, which releases a new video every two weeks, Dr. Hayhoe explains the science behind global warming and addresses many myths about…

This week’s question from the Georgia Climate Project’s Roadmap deals with the impacts of our transportation system on emissions of carbon dioxide and other greenhouse gases. Transportation is a big input to these emissions and how our regional and local methods of moving goods and people around evolve in the future will affect how much…

A megadrought is a strong and persistent drought that can last for one, two or three decades. While the US has not seen a real megadrought since climate started being measured here in the 1800’s, tree rings and lake sediments can go back much farther in time and tell a different story. There have been…

What makes weather oppressive to you? For most people, it is probably a combination of heat and humidity. Climatologist Brian Brettschneider has put together a Forbes blog post which describes how he calculated how he used climate data to calculate which parts of the US have the most days with “oppressive” weather. As you can…

As the Arctic warms up and sea ice melts, it is changing the large-scale weather patterns that help move storms around. These steering currents affect the movement of mid-latitude low pressure centers, but also help push around tropical storms and hurricanes. A new study of the impacts of this shift in the big atmospheric wave…

If we want to understand the climate of the future, it is important that we first understand the climate of the past. Unfortunately, weather records only go back about 150 years. To look climates on longer time frames, we need the help of paleoclimatologists who look at proxy data like tree rings, lake and ocean…
