Michael Mann: “We literally would not have seen these extremes in the absence of climate change.”

“Extreme weather has struck across Europe, from the Arctic Circle to Greece, and across the world, from North America to Japan. “This is the face of climate change,” said Prof Michael Mann, at Penn State University, and one the world’s most eminent climate scientists. “We literally would not have seen these extremes in the absence of climate change.”

The impacts of climate change are no longer subtle,” he told the Guardian. “We are seeing them play out in real time and what is happening this summer is a perfect example of that.”

First decent summer in Europe for ages, especially UK and this nonsense is delivered.

We haven’t seen blocking patterns in summer before in the NH?
Climate change apparently causes blocking patterns and without it, the usual zonal jet stream would had occurred?

These blocking patterns occurring especially in the Northern Hemisphere always had occurred at times in past history and given extreme weather around the world. So numerous that every decade can be included since recorded instrumental data began. The oldest data in the world being the CET, highlights these extremes throughout from the 17th century.

Blocks in meteorology are large-scale patterns in the atmospheric pressure field that are nearly stationary, effectively “blocking” or redirecting migratory cyclones. They are also known as blocking highs or blocking anticyclones.[1] These blocks can remain in place for several days or even weeks, causing the areas affected by them to have the same kind of weather for an extended period of time (e.g. precipitation for some areas, clear skies for others).[2] In the Northern Hemisphere, extended blocking occurs most frequently in the spring over the eastern Pacific and Atlantic Oceans.[1]

Polar cyclones are climatological features which hover near the poles year-round. They are weaker during summer and strongest during winter. When the polar vortex is strong, the Westerlies increase in strength. When the polar cyclone is weak, the general flow pattern across mid-latitudes buckles and significant cold outbreaks occur. Extratropical cyclones which occlude and migrate into higher latitudes create cold-core lows within the polar vortex.[3] Volcanic eruptions in the tropics lead to a stronger polar vortex during the winter for as long as two years afterwards.[4] The strength and position of the cyclone shapes the flow pattern across the hemisphere of its influence. An index which is used in the northern hemisphere to gage its magnitude is the Arctic oscillation.[5]

Omega blocks are so-named because the height fields with which they are associated in the Northern Hemisphere resemble an Ω, the uppercase Greek letter omega. They typically have a low-high-low pattern, arranged in the west–east direction.[2]

An example of a rex block off the West coast of North America in January 2007
Rex blocks (or dipole blocks) consist of a high situated poleward (north in the Northern Hemisphere; south in the Southern Hemisphere) of a low. Very often both the high and the low are closed, meaning that the isobars (or constant geopotential height lines) defining the high–low close to form a circle.[6] Rex blocks are named after the meteorologist who first identified them.[7]

Won’t hurt being wrong one more time when wrong so often before.

There is zero indication that humans have had any affect on blocks in the NH or SH and without this evidence, impossible to claim any extreme weather has been caused by any human climate change whatsoever.

So the “change” in the average of the “whole” of global weather, as created in the collective mind of humans, is now creating extremes in local weather…. WOW! So does that mean if WE just stop averaging the weather the “extremes” will stop? Or do we just stop/ignore the “change”?? Oh, and is that “change” + or -?? Oh #2, can someone please define what constitutes “change”?
