What Fresh Hell Is This?

Reality Invades Trumpville

From the AP (via the Military Times):
Directly contradicting President Donald Trump, U.S. intelligence agencies told Congress on Tuesday that North Korea is unlikely to dismantle its nuclear arsenal, that the Islamic State group remains a threat and that the Iran nuclear deal is working. The chiefs made no mention of a crisis at the U.S.-Mexican border for which Trump has considered declaring a national emergency.
Let's all remember what the orange one said:

And then there's this from the orange vulgarity:
Waming? Oh well, here's what the science says:
But how is global warming to blame [for the shifting polar vortex]?

The answer is simple: because the phenomenon that causes the polar vortex to break down is known as sudden stratospheric warming, where the upper layers of the atmosphere increase in temperature by approximately 30–50 °C (54–90 °F) over the span of only a few days. The fact that there are land masses located where they are in the northern hemisphere means that as those land temperatures increase, they transport their heat to even more northern latitudes.

The exact details of how this works are complex, but the explanation is simple: warmer land temperatures, particularly in northern North America and northern Eurasia, allow more heat to be transported into the Arctic stratosphere. A warmer Earth makes sudden stratospheric warming events more likely and more frequent. And those events destabilize the polar vortex, bring cold air down into the mid-latitudes, and cause the extreme weather we're experiencing right now.
Sadly, none of this matters to the current occupant of the Oval Office.
