Well, knock me down with a feather

The United Kingsom’s premier fount of global warming hype, The Guardian has an article with a sub-heading in a large font which says:Quote.

?The northern hemisphere is having a baking summer ? and it?s not just down to climate change.?End of quote.

Wait, what?? A heatwave and the Guardian is not blaming climate change or global warming or CO2.? Clearly, the heat has nurgled their brains.

Unfortunately, by the time the 2018 northern hemisphere heat wave made it to the TV1 Six O’clock news, global warming was the culprit, although exactly how mankind had moved the jetstream was not explained.

But back to the Guardian: Quote.

[…] Far from being a parochial problem, the current heatwave is clearly an issue that affects vast stretches of our planet: a global concern not a local one.

But why is so much of our world currently being afflicted with blisteringly hot weather? What is driving the wildfires, the soaring temperatures and those melting rooftops? These are tricky questions to answer, such is the complex nature of the planet?s weather systems. Most scientists point to a number of factors with global warming being the most obvious candidate. Others warn that it would be wrong to overstate its role in the current heatwaves, however. End of quote.

“Most” wouldn’t be 97% by any chance?? Quote.

?Yes, it is hard not to believe that climate change has to be playing a part in what is going on round the globe at present,? said Dann Mitchell of Bristol University. ?There have been some remarkable extremes recorded in the past few weeks, after all. However, we should take care about overstating climate change?s influence for it is equally clear there are also other influences at work.? End of quote.

Oh my goodness, Dann, is your University tenure safe, making statements like that? Quote.

One of those other factors is the jet stream ? a core of strong winds around five to seven miles above the Earth?s surface that blow from west to east and which steer weather around the globe. Sometimes, when they are intense, they bring storms. On other occasions, when they are weak, they bring very calm and settled days. And that is what is occurring at present.

?The jet stream we are currently experiencing is extremely weak and, as a result, areas of atmospheric high pressure are lingering for long periods over the same place,? added Mitchell.

Other factors involved in creating the meteorological conditions that have brought such heat to the northern hemisphere include substantial changes to sea surface temperatures in the North Atlantic. ?These are part of a phenomenon known as the Atlantic multidecadal oscillation,? said Professor Adam Scaife, of the Met Office.

?In fact, the situation is very like the one we had in 1976, when we had similar ocean temperatures in the Atlantic and an unchanging jet stream that left great areas of high pressure over many areas for long periods,? said Scaife.

?And of course, that year we had one of the driest, sunniest and warmest summers in the UK in the 20th century.?

However, there is one crucial difference between 1976 and today, added Professor Tim Osborn, director of research at the Climatic Research Unit, University of East Anglia. ?The baseline on which these effects operated is very different today. Since 1976 we have had several decades of global warming ? caused by rising carbon emissions ? which has raised baseline global temperatures significantly.? […] End of quote.

Phew, just when we thought all was lost and climate change had escaped the blame, that bastion of climate truth, the?University of East Anglia rides into town to put things back on track.? It is sooooo much worse now because of the prior decades of global warming. Yup, we are up about 0.13C or something equally frightening. Quote.

As a result, any phenomenon such as the weakening of the jet stream is going to have a more pronounced effect than it did 40 years ago.

And as global carbon emissions continue to rise and predictions suggest the world will be unable to hold global temperature rises this century to below 2C above pre-industrial levels, widespread heatwaves are very likely to get worse and become more frequent, scientists warn. End of quote.

And “carbon” emissions?are going to push us over the 2C limit.

Oh dear, what a shame. For a short while there, I thought the Guardian might be cooling off the climate crisis.

Should have taken more note of the “just” in the sub-heading.
