How Stupid Does David Rose Think You Are?

Earth is heating up, fast. This year we’re destined to set a new record for hottest year globally … for the third year in a row. Sea level is now high enough that coastal cities are spending hundreds of millions of dollars to fight flooding they get even when there’s no rain or wind or storm … just high tide. Arctic temperatures lately have been crazy hot, not just hot, but crazy hot, while sea ice in the Arctic and the Antarctic is at all-time lows for this time of year. Greenland ice is disappearing before our eyes. Heat waves are on the rise, killing thousands. Persistent drought plagues the U.S. southwest, but in other areas, when rain does fall it’s heavier than it used to be, causing once-in-a-thousand-years flooding to become a lot more common that once in a thousand years. Climate has been changing, not for the better, and it still is.

Which Satellite Data?

There are five data sets of global average temperature in the troposphere (the part of the atmosphere where our weather occurs) based on satellite data, from the two main providers, RSS (Remote Sensing Systems) and UAH (University of Alabama at Huntsville). UAH provides two of them: TLT (temperature in the lower troposphere) and TMT (temperature in the mid-troposphere); while RSS provides three: TLT, TMT, and TTT (temperature in the total troposphere). They’re all different, and each has gone through a number of revisions since the satellites began collecting data in 1979.

The Rain in Maine

One of the side-effects of global warming is that warmer air can hold more water vapor. In particular, storm clouds can hold more water so they can dump more water on the land. Sometimes it’s true that “when it rains, it pours.”

Climate Change: the Fish Notice

One of the most pernicious arguments from climate deniers is that “a few degrees” doesn’t have much of an effect. After all, if you raise the temperature of the room you’re sitting in by a “mere” 1°C (1.8°F), you might not even notice.

Nature notices. The fish notice.

Sea Ice, North and South

Arctic sea ice has been in decline so long, and so far, that deniers have had to make up some truly ludicrous stories about it. They embarass themselves on the topic.

But for some time, they crowed about the actual increase of Antarctic sea ice. They rarely mentioned that its increase wasn’t as great as the Arctic decrease (or they outright lied and said it was). They also tended to add the Arctic and Antarctic extents together to form a global figure, because the Antarctic increase partly cancelled out the Arctic decrease, making it seem not so bad.

For now at least, they won’t be crowing.

Supermoon Flooding

You may recall when I posted about flooding from high tide alone, even without storm surge or rainfall. It’s because of sea level rise. No doubt. It’s getting worse. No doubt.

NASA has just released their latest global temperature update (the latest value is shown in red):
