Warmest 13 years in History Globally since 1997

The WMO, part of the United Nations, said the warmest 13 years of average global temperatures have all occurred in the 15 years since 1997. That has contributed to extreme weather conditions which increase the intensity of droughts and heavy precipitation across the world, it said.
Global temperatures in 2011 are currently the tenth highest on record and are higher than any previous year with a La Nina event, which has a relative cooling influence," it said end quote.

So, since this 2011 is the hottest year ever in a La Nina condition which tends to reduce world temperatures, we can expect more extremely hot weather than this year in the future. The heat tends to increase winds of all kinds worldwide.

If you study the physics of what causes winds around the planet there are two basic factors and a whole lot of smaller ones. The two big factors that generate winds are the spinning planet which tends to spin under the atmosphere of air and the atmosphere of air is sort of alike an ocean of air. But because the air is thinner it tends to stay in one place more as the planet moves under the air at about 1000 miles per hour as it rotates 24 hours a day. The second major factor is heat from the sun. When heat from the sun hits the earth, the earth either absorbs the heat if it is beige or darker like water or some rocks, or it reflects the heat if it is white like snow. But, now all the snow is starting to melt out of the Arctic every year around September and October, there is a whole lot of more blue water that will absorb the heat. The biggest effects of the heating of the air is over deserts and mountains.  When air is heated in the deserts for example, it begins to rise faster and faster depending how warm or hot it is. This causes a suction as the air rises of other air on the ground and causes sometimes really great winds. In the winter the opposite happens as cold air falls and this pushes the air that was on the ground away from that area which also causes great winds.
