climate change – Paranormal Activity

Climate Scientist responds to Sabine Hossenfelder on Climate Sensitivity

ClimateAdam — Fri, 02 Feb 2024 15:36:48 +0000

How hot will our planet actually get? Climate scientists try to answer this question by evaluating the “climate sensitivity”. And if you’ve watched the recent Sabine Hossenfelder, you may be left with the impression that climate change wasn’t much to worry about… but now it is. So I’m here to explain what the evidence is actually showing us, and why the situation is a little more nuanced than Sabine’s commentary may have suggested. And crucially I break down how climate scientists arrive at a number for the crucial “climate sensitivity”, to give us a sense for how much global warming we’re in for.

Greece extreme weather: Widespread flooding just days after wildfires brought under control

Channel 4 News — Wed, 06 Sep 2023 18:59:13 +0000

Torrential rain has caused widespread flooding in Greece, just days after the deadly wildfires that raged across the country for weeks were brought under control.

At least 12 people are known to have died in the floods caused by downpours that have also hit Turkey and Bulgaria.

Meanwhile, the UN has confirmed that the northern hemisphere in 2023 has had its “hottest summer on record”.

Is Earth’s Largest Heat Transfer Really Shutting Down?

PBS Terra — Tue, 22 Aug 2023 18:08:06 +0000

Check out Sharks Unknown: https://www.youtube.com/watch?v=AS2FdIcqlqg

With unprecedented heat waves and record-breaking global temperatures, it’s hard to believe that there might be a place on earth that has actually COOLED since the industrial revolution. But, it turns out, there is such a spot. The COLD BLOB off of Greenland mystified scientists for years, but new studies have uncovered a scary reality – this cool patch might be a warning of the impending collapse of a vital earth circulation system. And the consequences would be dire.

In this episode of Weathered, we travel to the Gulf Stream with the new PBS Terra show Sharks Unknown to experience the AMOC first hand. And we ask, what is the likelihood that the AMOC will collapse, and what would the consequences be?

Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

Extreme weather: glacial flooding, wildfires and hailstorms cause havoc across the world

Guardian News — Wed, 09 Aug 2023 14:35:52 +0000

Countries across the globe are facing a range of extreme weather events. In Germany, snowploughs were deployed in the middle of summer to shift ice from roads after a hailstorm. Subscribe to Guardian News on YouTube ► http://bit.ly/guardianwiressub

Severe flooding has affected parts of Europe including Sweden and Slovenia, with hundreds of houses submerged. Human-caused climate change is supercharging extreme weather across the world, driving more frequent and more deadly disasters from heatwaves to floods to wildfires.
