One demonstrable side-effect of climate change is a radical upsurge in lightning activity in the far northern Arctic (latitude greater than 80 degrees).
Another sign things are getting weird: Lightning around the North Pole increased dramatically in 2021

Lightning increased significantly in the region around the North Pole, which scientists say is a clear sign of how the climate crisis is altering global weather.

Vaisala, an environmental monitoring company that tracks lightning around the world, reported 7,278 lightning strokes occurred last year north of 80 degrees latitude, nearly twice as many as the previous nine years combined.

Arctic lightning is rare -- even more so at such far northern latitudes -- and scientists use it as a key indicator of the climate crisis, since the phenomena signals warming temperatures in the predominantly frozen region. ...

The annual number of lightning strokes in the Arctic -- the region north of around 65 degrees latitude -- has remained consistent over the past decade, but it is now surging significantly in the extreme north. ...

A set of newly-published research reports in Nature further extend and refine prior concerns about the effects of thawing Arctic permafrost.
Thawing Permafrost Is Poised to Unleash Havoc in The Arctic, Scientists War

Thawing Arctic permafrost laden with billions of tonnes of greenhouse gases not only threatens the region's critical infrastructure but life across the planet, according to a comprehensive scientific review.

Nearly 70 percent of the roads, pipelines, cities, and industry – mostly in Russia – built on the region's softening ground are highly vulnerable to acute damage by mid-century, according to one of half-a-dozen studies on permafrost published this week by Nature.

Another study warns that methane and CO2 escaping from long-frozen soil could accelerate warming and overwhelm global efforts to cap the rise in Earth's temperature at livable levels.

Exposure of highly combustible organic matter no longer locked away by ice is also fueling unprecedented wildfires, making permafrost a triple threat, the studies report.

Blanketing a quarter of the northern hemisphere's land mass, permafrost contains twice the carbon currently in the atmosphere, and triple the amount emitted by human activity since 1850. ...

Mount Everest: Mountain's highest glacier melting rapidly, new study shows​

News story

Locally, this is bad for the Himalayas because they depend on the water for irrigation of crops. Globally, it's following a pattern of warming that threatens us all. 2000 years to form one glacier, a fraction of that to melt it.

People are so obsessively focused on global warming that they are ignoring the converse threat, namely that periods of widespread glaciation in Earth's past have been preceded by periods of extreme warmth. Apparently the Arctic Ocean was open water at the onset of the last great Ice Age. And the transition from one to the other can be shockingly swift, as little as twenty years or so.

Either way, civilization is facing a severe test.

More than half of plants rely on animals to disperse their seeds far and wide.

In the face of climate change, birds and mammals are these plants’ best chance at putting down roots in a more suitable environment. Unfortunately, many birds and mammals that carry these seeds have experienced staggering losses to their population—some large seed haulers, such as woolly mammoths, are extinct. A study published in Science last month created models that could forecast future interactions between animals and plants as their habitat ranges shift, and how species losses up until now have reduced the distance seeds can travel. Watch to see the areas around the world hardest hit by these declines, and the tactics that could increase plants’ resilience to climate change in the future.

I will always believe what my Father told me, that the earth goes through cycles of heating and cooling, every 10,000 years or so.
The ice caps melt, the earth heats up, all the condensation entering the atmosphere from the heating of the earth's oceans eventually cools things down again, and the earth goes into an ice age phase, much of life is lost. Then slowly things start to heat up again.
Has to be somewhat true, considering the evidence of worldwide flooding thousands of years ago.
At least thankfully none of us will be alive to have to deal with it.

Since when do the big buggers from September intrude on winter?

Since Winter warmed up by about ten degrees C or something.
I live in the north of England. Snow was a yearly event when I was a kid. Still live in the same town and barely a flake since 2018. Haven't seen a hard frost this winter, or last .

Climate change: IPCC report warns of ‘irreversible’ impacts of global warming​

News story

Looks like we just left it too late. But there is hope (quote from article):

"If our development pathways are ones in which health systems don't improve much, education doesn't improve much, our economies aren't growing very fast and inequality remains a big problem, that's a world where a particular amount of climate change is going to have a really big impact," said Prof Brian O'Neill, an IPCC coordinating lead author from the Pacific Northwest National Laboratory in the US.

"In contrast, if it's a world where we are really making rapid progress on education and health and poverty, if climate change is imposed on that society, the risk will be much lower."

(end quote)

Hope that's of some comfort to those currently suffering in South America, Africa, Australia, Asia... oh, pretty much everywhere. I'm kind of ashamed of complaining about Storm Eunice now.

Oh noes! But at least that’ll mean that they shut up, right?

You yourself posted a news story on the recent Brazilian mudslides that killed over a hundred people. Maybe you would like our Australian board members not to mention the massive flooding there at the moment?

Basically, the world's gone mad. But let's not turn this into the Fortean Ukrainian Board.
I think the world went mad a very long time ago. It's not a new phenomenon.

None of this is real. We are just confused NPCs in a simulation. Notice how the drama is getting ramped up for a Boss Fight?

Well here in NJ we really see the effects of this climate change - living on a river you see it firsthand.
These days even a 10 minute thunderstorm can turn into a frightening street flood.
As for the hurricanes, it's several feet of water filling the basement and going right into the first floor. This is in the last 20 or so years, never happened like this before in our lifetime.
And it's continual moving of vehicles to higher ground. September 1, 2021, the remnants of Hurricane Ida moved through here - hundreds of cars in our immediate area were flooded and towed away. Because we've been through it before, we moved our vehicle to a safe location before the hurricane arrived so we were ok.

Just watched BBC after a bitofa hiatus. It seems like a few of their reporters were green screened against a movie backdrop. Sarah Smith and Clive Myrie in particular.

It is a dire situation for the world, and never seen before.

The Snow and Ice Data Center in Boulder, Colorado says never before both the Arctic and Antarctic are running 50 to 70 degrees above normal.

It is hoped the Southern Hemisphere is starting to towards winter and Antarctica will start to cool.

It seems warm air from the Pacific is going to places that it has never gone before.

Never before an ice area the size of Los Angles collapsed from the Conger Ice Shelf in the Antarctica.

This is an area called Wilkes Land.

Lately, rivers of warm air from the Pacific have been streaming into both the north and south poles.

Scientists are hoping that Southern Hemisphere winter will return soon.

The U.S. Weather Service, The British Met, and the EU weather service all have agreed that La Niña currents are still in place and will cause extreme heat this summer across the U.S., the UK, and Europe.

The Met has predicted maybe some parts of the UK will see 40 C.

I hope this does not happen.

I too hope this does not happen, those currents gather into dreadful hurricanes and tornados.
And who needs 104 Degree heat and humidity!

So true, early predictions show an active hurricane season.

In the southern U.S. states this year we have had already damaging tornadoes.

It seems the “ tornado alley “ over the west and Kansas has move over the south.

And up here in the Northeast, we have already had a very early and warm Spring, it was 80 Degrees or more here yesterday already.
Here comes a hot summer!
