The Year Gone By...
The Years to come?
Climatology can be counterintuitive: The heating of arctic air causes a diminuation of temperature difference between the circulating polar vortex which in turn cause cold arctic air to break out into temperate zones of the northern hemisphere. Paradoxically, warming of arctic air results in cooling of temperate air. This represents a break-down in the normal functioning of the climate system.
In the southern hemisphere, the warming air increases air currents which whip the superficial waters and causes it to suck up warmer deep waters (!) resulting in melting pressures on the Antarctic glaciers, remarkably many of which are on land below the water line. Hence higher winds cause greater warming in Antarctic waters.
Another little known property of the ice caps is their mass having a gravitational (!)attraction on the surrounding waters which "swell up" around the continental shelf so loss of ice mass >>loss of gravitational attraction on surrounding waters>> declining(!) sea levels release waters than end up rising distant coastal waters.
There are many counterintuitive effects like tis which give the lie to the notion that global warming--whatever the cause--means that local areas just get warmer. The phenomenon is far more complex with cooling interacting with warming. The net effect has more to do with human geography i.e. where 7 Billion people have decided to live and most commonly this is near coastal waters.
There Were a Crazy Number of Record Highs in 2016
2016 will be remembered for many things. One of them will be heat.
It was the hottest year on record globally. While the world is still waiting for confirmation of just how high the record was, thereís a lot of data to digest from the U.S. Nearly every square inch of the country was dramatically warmer than normal.
The blistering pace of record-high temperatures across the country is the clearest sign of 2016ís extreme heat. Record-daily highs outpaced record-daily lows by 5.7-to-1 in 2016, according to preliminary data from the National Centers for Environmental Information. Thatís the largest ratio in 95 years of record keeping. Put another way, 85 percent of extreme temperature records set in 2016 were of the hot variety.
That fits with the fact that 2016 will be the second-hottest year on record for the U.S. during which 98 percent of weather stations had a warmer-than-normal year.
Each month had more record highs than lows, in many cases by a large margin. November saw an incredible 48 record highs for every record low and February, March and October werenít that far behind. Even December ended up just being kind of cold and still finished the month with more record highs than lows, despite some headlines trumpeting a cold snap the likes of which was unseen in decades.
More record highs than record lows is exactly what youíd expect in a warming world and the trend has been tipping toward more and more highs compared to lows for decades. The 2010s are on track to have the highest ratio of record highs to record lows of any decade on record. The decade is currently on pace to see highs beat lows by roughly 2-to-1. (Without climate change, you would expect the ratio to stay 1-to-1.)
That includes a stretch of 25 months in a row where record highs outpaced lows. According to Guy Walton, a meteorologist who tracks the NCEI numbers, itís the longest such stretch since accurate record keeping of daily weather stats began in 1920.
If carbon pollution keeps increasing, temperatures will rise and make the ratio even more lopsided. Recent research shows that by midcentury, the ratio could reach 15-to-1 if carbon pollution continues on its current track. That means summers could have more days where itís unsafe to be outside. Winters could also have more mild days, which sounds nice in theory, but could unleash a host of negative impacts from hurting communities that rely on winter tourism to affecting maple syrup production.
So while 2016 holds the title for the wildest record ratio, itís only a matter of time until it gets beat.

I would suspect that all the cities where Donald Trump spoke generated significant contributions to Global warming , only, surpassed by the cities where the the Democrats had exponential levels frustration .http://www.youtube.com/watch?v=JOtab0BKOGY
