The global warming briar patch

Don't throw me in there!

It has been a long time since RtO has visited the question of global warming. In one sense nothing has changed -- claims about the amount of warming since the late 19th c. remain bogus because nobody knows what the temperature was then.

Some things more contemporary are not changing either, at least not in the way the alarmists promised.

More and worse storms. No hurricane has come ashore in Florida since Wilma in 2005.

Changes to growing seasons causing losses in agriculture. Let's see what the AP has to say today:

Farmers set corn and soybean records last year, harvesting the largest crops ever, thanks to a cool summer that made for mostly favorable conditions, the U.S. Department of Agriculture reported Monday. Farmers harvested 14.2 billion bushels of corn, 3 percent more than in 2013, and 3.97 billion bushels of soybeans, up 18 percent.

UPDATE In further global warming news, it is snowing in Arabia and some Muslims have been condemned for making snowmen and snowcamels.

And, no, this is not a joke on any level.

SECOND UPDATE It turns out we don't know how much sea levels have risen, and for exactly the same reasons we don't know how much temperatures have risen:

Given that observers have been taking measurements at harbors for centuries, using devices called tide gauges, it might seem a simple problem to figure out how much the ocean has been rising. It is anything but simple, though: The tide-gauge record is plagued by gaps; the land to which many of the gauges are attached has itself moved over time; and factors like wind and ocean currents can cause variability of the sea level in particular locales. Moreover, the early harbor measurements were concentrated in Europe and the United States, leaving much of the world a blank.
