<p>NASA recently released a study suggesting that the Antarctic Ice Sheet is gaining more ice than it is losing — a finding that, at first blush, seems to contradict the idea of global warming. So, how can Antarctica be gaining ice mass in a warming world where ice sheets are collapsing and the melting is predicted to increase sea levels across the globe?</p>

Lately, it seems like wildfires are everywhere. This year, North America had a horrific fire season, and with record droughts persisting and temperatures increasing it's only going to get worse. Meteorologists are often on the front lines, predicting how and when a wildfire will move or grow, but they are stretched thin as more fires rage, and are entirely dependent on people to report a fire to the authorities. Now, NASA is introducing a tool that it hopes will make forecasting and fighting fires easier. Meet FireSat. Wildfires often get 'wild' when they begin in a rural area where fewer people are around to notice the growing flames. Now, NASA plans to detect fires from space, no people needed. FireSat will be a network of 200 satellites equipped with temperatures sensors encircling the entire globe. The sensors would be able to detect fires when they are 35-50 feet wide (so don't worry, no one will be taking pictures of your backyard barbecue) within 15 minutes of their start. NASA hopes to have the network, which can also be used to monitor explosions and oil spills, operational by June 2018. FireSat would also be able to send images of a fire to first responders once every minute, so that they can see how fire conditions are changing in something closer to real time. (Currently, satellite images capture a fire twice a day). So in 2018, NASA might be monitoring Burning Man from space.

The Northern Hemisphere may be subject to more cold outbreaks than usual come January thanks to the polar vortex. "Polar vortex" became a household phrase in North America during the bitterly cold winter of 2013-2014, but this phenomenon has always existed and can also impact both Europe and Asia. The polar vortex is one of the factors that control how much cold Arctic air is allowed to infiltrate the mid-latitudes during the winter, when the vortex is at maximum strength.

This year’s El Niño officially climbed to the top of the record books (at least by one measure). Weekly data published by the National Oceanic and Atmospheric Administration shows that the region of the Pacific generally used to gauge El Niño’s strength has officially surpassed the 1997-98 super El Niño in terms of warmth. The hot waters in the Pacific are helping drive up temperatures globally as well as affect the world’s weather.
