8:40 PM | Are Tornadoes Starting To Move In Swarms?
A new study looking at the last 59 years of tornadoes in the United States reveals something surprising: We have fewer tornadoes today than we used to. But those tornadoes are hitting in a terrifying new way.Read more...

4:29 PM | Prehistoric climate – wish you were there?
Last week I wrote about how cyclical variation in Earth’s orbit influences the long-term climate here on the surface. I also left you on a cliff-hanger promising knowledge of how we know what we know regarding climate in the deep past. This week, I give you the answer: oxygen. Atoms or isotopes? A very quick […]

7:49 PM | U.S., Military to Plan More Strategically for Climate Change
Climate change is a “threat multiplier” and worse than many of the challenges the U.S. military is already grappling with, according to a new report by the U.S. Department of Defense (DoD). The New York Times indicated that the report marks a departure from the DoD’s previous focus on preparing bases to adapt to climate…

4:48 PM | Earth’s magnetic field could flip within a human lifetime
Earth’s last magnetic reversal took place 786,000 years ago and happened very quickly, in less than 100 years — roughly a human lifetime. The rapid flip, much faster than the thousands of years most geologists thought, comes as new measurements show the planet’s magnetic field is weakening 10 times faster than normal and could drop … Continue reading →

9:38 PM | Two in Row- September Follows August as Hottest on Record. 2014 May Be Hottest Ever.
Just like August, September was the hottest on record globally (according to NASA). NOAA maintains a different record, and will report their number any day now. The data sets use slightly different methods, but it’s a good bet that they will show a new record as well. NASA also has a graph showing the heat anomalies by latitude: NOAA’s National Climate Data Center created a very good info graphic that …

7:16 PM | What Does Record-High Antarctic Sea Ice Say About Climate...
What Does Record-High Antarctic Sea Ice Say About Climate Change? Record lows in sea ice have been recently recorded in the Arctic but ice around the opposite pole of the planet is on the rise. This is probably not due to climate stabilization: The rate of sea ice loss is substantially more than the Antarctic growth-rate. But further study in ocean temperatures, wind direction and more is needed to explain why this is occurring. Credit: NASA Goddard Space Flight Center/Joy Ng Uploaded by: […]

2:47 PM | Eye on the Storm
Atmospheric scientist Adam Sobel is author of the new book Storm Surge: Hurricane Sandy, Our Changing Climate and Extreme Weather of the Past and Future.  Sobel, a native New Yorker, was at the center of the historic 2012 storm in more ways than one. As an expert in extreme weather and its relation to climate, he [...]

12:07 AM | El Nino Project (Part 8)
This time I’d like to compare a different paper on climate networks: • Y. Berezin, A. Gozolchiani, O. Guez and S. Havlin, Stability of climate networks with time, Scientific Reports 2 (2012). The goal of this paper is to see how stable over time climate networks over time. They divide the world into 9 zones: […]

2:02 PM | Human-made climate change, or climate change made humans?
We hear a lot in the news about accelerated climate change due to human activity, and for very good reasons. Just have a glance at the first half Intergovernmental Panel on Climate Change’s 2014 report (IPCC 2014 Summary) if you want to know how we’ll all be affected by climate change in our own lifetimes.

5:49 PM | Studies Focus on Warming of Oceans
Oceans absorb carbon dioxide and 90 percent of the heat caused by human activity—making their warming a critical topic for climate research. Two new studies—one on the upper oceans and one on deeper ocean depths—share findings about climate change’s effect on these water bodies. The first study, in the journal Nature Climate Change, provides the first estimate of…

1:47 PM | Scientists turn Hurricane Sandy destruction into future readiness
This December, USGS will release a beta version of interactive computer models created from data collected by that laser-equipped plane—known as the second generation Experimental Advanced Airborne Research Lidar (EAARL-B)—and other equipment that mapped and monitored the New Jersey coast. The online portal will allow anyone to look at storm intensities and directions, evaluate wave attack scenarios and coastal vulnerabilities, and anticipate the impacts to landscapes ahead of time, […]

3:23 PM | Studies Link Climate Change to Recent Extreme Weather Events
New research in the Bulletin of the American Meteorological Society finds that climate change influenced the majority of 16 extreme weather events in 2013. Specifically, it found evidence that climate change linked to human causes—particularly burning of fossil fuels—increased the odds of nine extreme events: amplifying temperature in China, Japan, Korea, Australia and Europe; intense rain in parts of the…

12:21 PM | Sculpting Tropical Peaks
Max Cunningham, a graduate student at Lamont-Doherty, traveled to Costa Rica's Mount Chirripó this past summer to test the idea that mountain glaciers carved the summit we see today. He and his colleagues hope to eventually pin down when Chirripó's high-elevation valleys eroded into their current form. Check out a recap of their 2014 field season.
