3:13 PM | Climate, Water and Hay Aligned in Kittitas Valley
Climate, available irrigation water and good soils align in the Kittitas Valley to make this central Washington valley an attractive area for growing livestock feed. Some history might play a role as well.Climate in the Kittitas consists of warm and dry spring, summer and fall weather. Spring comes fairly early in the year and warm temperatures linger well into October (particularly this year!). Winters are cold with sub 0 degree F not unusual. In addition, the Kittitas Valley is a bit on […]

9:15 PM | Record Warm September Increases Odds that 2014 Will be Hottest on Record
From NOAA. From NOAA. NOAA announced today that both August and September were the hottest globally since reliable instrument records began in the 1880′s. From NOAA: Global Highlights The combined average temperature over global land and ocean surfaces for September 2014 was the highest on record for September, at 0.72°C (1.30°F) above the 20th century average of 15.0°C (59.0°F). The global land surface temperature was 0.89°C (1.60°F) above the 20th …

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: […]

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…
