<p>1. Fields around Morton, Illinois, produce 85% of the world’s canned pumpkin. The yield is down to half this year due to unusually heavy spring rains associated with global warming. We will be out of canned pumpkin in about a month.

<p>2. As we get more cheap solar and wind power, gas and coal plants sit idle for longer spells and they become more costly to operate per unit of power produced, which increases the use of solar and wind power, which makes them cheaper, which means we get
more wind and solar, which further diminishes the role of fossil fuels. This positive feedback loop is good news, in contrast to most of the positive feedbacks connected with climate.

<p>3. A NASA study finds that on balance the Antarctic is not losing mass due to melt, and probably will not begin to for around twenty years. Previous studies had found any mass gain in the East Antarctic overwhelmed by melting in the West. <a href="http://www.smh.com.au/environment/climate-change/antarctic-ice-loss-challenged-by-new-nasa-study-20151006-gk2gwm.html">http://www.smh.com.au/environment/climate-change/antarctic-ice-loss-challenged-by-new-nasa-study-20151006-gk2gwm.html</a></p>
