8:54 PM | Is our climate headed for a mathematical tipping...
Is our climate headed for a mathematical tipping point? Scientists have warned that as CO2 levels in the atmosphere rise an increase in Earth’s temperature by even two degrees could lead to catastrophic effects across the world. But how can such a tiny, measurable change in one factor lead to huge, unpredictable changes elsewhere? Victor J. Donnay uses billiards to illustrate tipping points, chaotic motion and their implications on climate change. View full lesson: […]

6:52 PM | Should Fracking Be Banned?
From KQED Education Do Now: On Tuesday, November 4, 2014 three counties in California will decide by ballot whether or not to ban hydraulic fracturing, otherwise known as “fracking.” It’s steeped in controversy, from the amount of water it uses to how and where that water--and added chemicals--are eventually disposed. Should fracking be banned? Why or why not?

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 …

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).

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 …

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: […]
