More and intense storms, too...
You have evidence for that assertion? The theoretical atmospheric science and recent observations that I've seen would indicate the opposite. Of course, the hurricane predictions every year are for more and more intense hurricanes, but at the end of the season, they've been below average. The damage from them goes up, but that's because of more and more expensive structures being built in their path.
 
You have evidence for that assertion?
"Higher temperatures also mean higher-intensity tropical storms with higher wind speeds, which could cause more damage. Also, there is evidence that extra water vapour in the atmosphere makes storms wetter. During the past 25 years, satellites have measured a 4 per cent rise in water vapour in the air."

 
I thought climate change caused drought? How is that the case if the amount of moisture in the air is increasing?
 
No, as I've pointed out several times, the accumulated cyclone energy in each year is very variable and there's a slight downward trend even given the first 8 low energy years, and we can even use thermodynamics to explain why we'd expect this, due to the warming Arctic. The apparent fact that the climate establishment doesn't know thermo or is willing to ignore it for the sake of a headline to scare teenagers is a bit of a worry.

A blurb from a random internet site without even a name of the author attached, asserting that's what will happen. Yeah, real convincing. :rolleyes:Got any credible evidence (AKA data) that supports the assertion? Surely with the massive temperature increases we've already seen, there should already be a noticeable increase in the frequency and intensity of storm activity, if the assertion is true.

Edit: I did find this on the site "The lead developer of Internet Geography is Anthony Bennett. Anthony is a qualified geography teacher with a BA (Hons) in Geography." Seems like an expert on global atmospheric dynamics to me.:rolleyes:

Hmm, apparently it's ok to post woke climate change bad crap if you don't know thermo (structural engineers and map enthusiasts included) , but woe betide if you criticise based on actual data and 0-3LOT. I doubt you'll beat 0-3LOT. And of course if you don't even understand them then why are you even playing?
 
So there are no global air currents to move moisture about, got it.
 
A statement utterly unsupported by the article. This is an internet technique known as Gish Galloping, wasting other people's time with irrelevant drivel.
 
2024 numbers haven't been collated yet

In 2023 65% of China's electricity was fossil fuel. Coal usage is increasing, not falling

Europe’s Warmest Year on Record—Striking Climate Contrasts in 2024​



"The European State of the Climate 2024 (ESOTC 2024) report, jointly published on 15 April by the Copernicus Climate Change Service (C3S) and the World Meteorological Organization (WMO), reveals that 2024 was the warmest year, both for Europe and globally, since records began. Across the continent, people experienced dramatic and contrasting climate conditions. While the east faced dry, scorching heat, the west endured heavy rainfall and flooding, marking a year of profound and disruptive climate extremes."
 
How is a year of extreme weather (if that was the case) anything to do with climate? The IPCC defines climate as a statistical description of the average weather over a period of time, typically 30 years.

The U.N. Intergovernmental Panel on Climate Change (IPCC) admits having “low confidence” in any climate change impact regarding the frequency or severity of floods. There has been no evidence of increasing flooding frequency or severity as the climate modestly warms.

The U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe.

On Page 90 – Chapter 12 of the UN IPCC Sixth Assessment Report. Emergence of Climate Impact Drivers (CIDs) under the “Wet and Dry” section note that “Hydrological drought” is not detected as a result of climate change. “Agricultural and ecological drought” is also absent.

They also hilariously have a high confidence bet each way on mean precipitation
