Summit cross also lost.

Part of a Swiss mountain's summit has collapsed, sending more than 3.5 million cubic feet (100,000 cubic meters) of rock crashing into the valley below. The incident was likely a result of thawing permafrost — and scientists have warned similar events are to be expected as climate change causes ancient frozen ground to degrade.

The incident occurred on June 11 after an extensive period of high temperatures in the country. Videos reveal the sudden collapse of Fluchthorn's summit, an almost 11,155-foot (3,400 meters) mountain in the Silvretta Alps, on the border of Switzerland and Austria.

"Half of the summit was torn away by the demolition," mountain rescuer Riccardo Mizio told Austrian newspaper Kronen Zeitung (translated), adding the summit cross — a Christian cross marking the peak of a mountain — was missing. No one was injured by the rockfall.

Wow, I had heard of buildings sinking into bogs as permafrost melted, but mountain tops crashing into valleys is a bit mad.

Wasn't there also catastrophic flooding in the high mountain passes in India too as glacier sheets collapsed?

Just found this explanation:
"Marine heatwaves (MHWs) are characterized by unusually warm water temperatures that persist for extended periods. The world’s oceans act as Earth’s great heat reservoir, and have absorbed over 90% of the excess heat trapped by greenhouse gas emissions. While this has slowed the rate of atmospheric warming, it has come at a cost: the intensification of MHWs. These extreme events can have devastating consequences, and can potentially cause widespread bleaching of coral reefs, the proliferation of harmful algal blooms, the displacement of marine species, and the disruption of entire food chains."

Oddly cool around Australia, and what is it that's so hot off the coast of South America?

I don't know Myth, but googling came up with this: https://www.livescience.com/first-off-axis-pacific-hydrothermal-venting

As for Cool waters around Australia, when I was a school lad, we'd do a yearly Life Saving qualification event in September at the local Ocean Pool, and the Temp was always no higher than 17 degrees Celsius (62 F).

Quite brisk for a group of young teens I'd venture to say.
 

Jet stream goes bonkers​

The current map of the jet stream over the US is like nothing climate scientists have seen. The flow of air is fragmented to the degree that one professor called it “insane”. The unusual disjointed pattern is fueling a heat dome plaguing the south-central US and Mexico causing extreme temperatures and deaths. Top climate scientist Michael Mann said the planet-wide wacky jetstream is not only likely affected by global warming but the El Nino event is playing a role. Record low sea ice also messes up the flow. It’s not expected that the extreme temperatures will end soon but continue through the next month. This type of scary instability will be the new norm as the planet warms. https://www.sciencealert.com/earths...-a-van-gogh-right-now-and-thats-a-big-problem

So... the thing that's responsible for the hottest area of heat isn't man-made emissions?

To be perfectly candid...

If the heating oceans were due to Atmospheric origins, then wouldn't the areas of heat be significantly hotter around those latitudes that had the warmer climate?

And then, with the Gyres in the major Oceans distributing the oceans contents around both hemispheres, wouldn't there be a more consistantly incremental spread of temperatures, latitude wise, due to those specific ambient atmospheric climates?

To have the intense variation in temperature that are indicated on both graphs, there needs to be a constant source of heat I reckon - a fixed source, and I can't come up with anything other than Hydrothermal venting...other than space lasers...
 
climate change shrinks brains!

A new study suggests a link between past climate changes and a drop in the size of the human brain – an adaptive response that emerges in an analysis of climate records and human remains over a 50,000-year period.

The research by cognitive scientist Jeff Morgan Stibel from the Natural History Museum in California adds to our understanding of how humans develop and adapt in response to environmental stress.

"Given recent global warming trends, it is critical to understand the impact of climate change, if any, on human brain size and ultimately human behavior." Stibel writes in his published paper.

The study looked at how the brain size of 298 Homo specimens changed over the last 50,000 years in relation to natural records of global temperature, humidity, and rainfall. When the climate got warmer, the average brain size grew significantly smaller than when it was cooler.

Stibel's prior research on brain shrinkage prompted this investigation because he wanted to understand its root causes.

"Understanding how the brain has changed over time in hominins is critical but very little work has been done on this subject," Stibel told PsyPost's Mane Kara-Yakoubian.

Might there be a correlation between brain size and diet?
Warm climate > farming > mostly vegetarian diet > smaller brains
Cold climate > hunter-gatherer > mostly meat diet > larger brains

OK, OK, I am a little biased in my conclusion, but...
 
No blade of grass.

The risks of harvest failures in multiple global breadbaskets have been underestimated, according to a study Tuesday that researchers said should be a "wake up call" about the threat climate change poses to our food systems.

Food production is both a key source of planet-warming emissions and highly exposed to the effects of climate change, with climate and crop models used to figure out just what the impacts could be as the world warms.

In the new research published in Nature Communications, researchers in the United States and Germany looked at the likelihood that several major food producing regions could simultaneously suffer low yields.

These events can lead to price spikes, food insecurity and even civil unrest, said lead author Kai Kornhuber, a researcher at Columbia University and the German Council on Foreign Relations.

By "increasing the concentration of greenhouse gases, we are entering this uncharted water where we are struggling to really have an accurate idea of what type of extremes we're going to face," he told AFP.

"We show that these types of concurring events are really largely underestimated."

The study looked at observational and climate model data between 1960 and 2014, and then at projections for 2045 to 2099.

Researchers first looked at the impact of the jet stream – the air currents that drive weather patterns in many of the world's most important crop producing regions.

They found that a "strong meandering" of the jet stream, flowing in big wave shapes, has particularly significant impacts on key agricultural regions in North America, Eastern Europe and East Asia, with a reduction in harvests of up to seven percent.

The researchers also found that this had been linked to simultaneous crop failures in the past.

One example was in 2010, when the fluctuations of the jet stream were linked to both extreme heat in parts of Russia and devastating floods in Pakistan, which both hurt crops, Kornhuber said. ...

Meh. I am very sceptical about 'record figures' when it comes to the weather.
As I have posited many, many times before, it's more to do with where the measurements are taken.
Such as the 'record' day last year here in the UK, in which the temp was 40.3 degrees Celsius on July 19 at Coningsby, Lincolnshire.
Next to the runway at RAF Coningsby, as 3 Eurofighters landed and taxied past the measuring station.

I dare say that when they speak of the 'average global temp' a similar effect is at play, in which each country submits it's daily high temp record and they all go into the 'global' figure.
Probably a bit of competition among weather people to claim the record too, so measurement stations are deliberately placed/used in places which are expected to produce a high figure.
 
OK, so is this the earth just doing “ it’s thing “ and can’t be stopped no matter what ?

I have heard that the earth goes through warm and cold cycles.

To protect our crops, we should drastically lower CO2 levels?
Lower CO2 levels will kill off the crops... surely?
We're getting muddled/contradictory thinking coming through.

Another example of muddled/contradictory thinking is this:

(a) There's a push for an increase in the use of solar panels for generating energy.
(b) There's also serious consideration of the use of geo-engineering to reduce the sun's rays.

Joined-up thinking is required! :headbang:

Crops were doing fine when the CO2 level in our atmosphere was 285 ppm, before industrialisation. The current level of CO2 is about 420 ppm. Lowering CO2 ppm from 420 back to 285 would not damage crops at all.
 
The basis of Global warming/Climate change is consumption.

Which determines our economy.

Until we come up with something that satisfies the 'Boards', and the 'Shareholders' to replace the basis of our economy, then nothing will change.

If we reduce consumption, the price of everything will increase.

CO2 taxes are tax deductible, so any penalty for the production of CO2 is either added on to a unit price, or reclaimed by clever little weasel taxation accountants.

Class 4 sites are at the lowest level of acceptability, therefore they are not junk sites by definition. What is this geezer's beef?

I think you'll find that his actual words were "that class is next to junk status"

Mis-quoting someone in order to denigrate them is rather poor form old chap.
