Yes and I'm afraid I think 500ppm is optimistic, I think the atmosphere will get to a point where it is bad for health - and not just our species.. Remember, 'co2 is plant food', 'drill baby drill' and how people from you and I to 'Hansen' and 'Mann' have been attacked.

Not happy thoughts, sometimes I wonder if humans are already starting to behave more oddly under the influence of increasing CO2 - we'll get scorned and ridiculed for that too....

And it continues (the above post was from March)

Stage of Women's Giro d'Italia shortened by 28km as finish threatened by 'unstable ice sheet' in the Alps at Colle de Finestre between Turin and Sestriere. The road had already needed clearing from a previous avalanche

This is something I've thought about before, and only seen discussed a handful of times. Living in permanent 500-600ppm co2 will affect health more than people realise.

We're already living in a thin smoke of the products of combustion that don't rain out. I think life has seen huge volcanic and massive fires and surivived but what centuries of exposure to high levels of CO2 will do is something I do wonder about - I think someone should make a lab where CO2 is controlled to 280ppm and see if it has any effect on people. It would be the only place on earth without a stuff atmosphere. Otoh, what will 40-45C heatwaves in mid latitudes do to humanity?

But, CO2, 'it's plant food init' so there's nowt to be concerned about 👍

"El Niño, an oceanic heatwave that occurs two to three times each decade, is building in the Pacific around the equator, and is expected to peak in September, the United Nations' World Meteorological Organization (WMO) has warned.

The warm current will affect weather patterns and increase the risk of droughts in Australia, and southern parts of Asia and Africa. It will also increase the likelihood of violent storms and heavy rainfall in parts of the Americas.

US scientists confirmed on Thursday that El Niño conditions were under way in the tropical Pacific after sea-surface temperatures rose sharply in recent months.

While droughts and storms are bad enough, experts say this could be the strongest El Niño on record, with even more severe potential outcomes. These include flooding, landslides, wildfires, famine, conflict and migration.

The expected severity has led to some meteorologists using the term Godzilla El Niño – after the colossal dinosaur-like creature that has featured in dozens of monster films.

""There's a lot been on the news quite recently about El Nino and the effects the global impact of this warm water current in the Pacific might have on the world as it has in the past," says Dr Robb Robinson, an honorary research fellow at the University of Hull. 

"That and its complementary current, the Humboldt current, the cold-water current, have been a subject of a lot of examination over the years," he adds.

"And one of the reasons we know quite a lot about it is that the foundations for our understanding of these currents in the Pacific, a lot of them were laid by a research ship called the William Scoresby."

Already 38.4C at La Rochelle, should be plenty of 40s across France today.

"By the way, on July 4th, it's going to be approximately 107 degrees out, and I'm gonna go and I'm gonna make a really long speech just to show that I can do anything," he [Trump] said.

The only comparable wildfire smoke event affecting this portion of North America occurred in 2023; a 2025 study blamed that event for 33,000 premature deaths in the United States, 8,300 in Canada, and 23,000 in Europe. According to the EPA, a premature air pollution death is one that occurs on average 14 years before a person would have otherwise died.

I guess this is Global warming 😂 

A significant severe weather outbreak is forecast across the north-central Mediterranean and the Adriatic Sea region on Sunday. Strong instability and highly sheared environments combine for widespread thunderstorm activity with large to giant hail, severe winds, tornadoes, and flash flood potential.
