Michael Mann

This is just in real time because it just popped up on my thing.

But Michael Mann accidentally shot himself today at a Los Angeles gun range.

He's transported to the hospital by ambulance.

Well, that's not good.

I'm sorry.

That just popped up.

shooting guns at a range.

very happy to find the...

the paper that was the main one that people like Michael Mann were then using to argue if we hit net zero, then climate heating stops.

And I analyzed it and published on it.

And it did include a lot of very, I would argue, so untenable it renders the study meaningless assumptions.

Oh,

sorry, I should say on that one, is that many other people are saying this.

So even critics like Michael Mann, who would just reject my work out of hand in the past, he's now put his name to the... uh 2026 world climate update with other top scientists and they say that we're already in a catastrophic situation which is beyond our ability to respond i could even find the quote here we are witnessing the rapid destabilization of the earth's climate system this is no longer a warning for the future it is a diagnosis of the present with changes unfolding faster than our ability to respond That was in Bioscience.

That's from the paper, not from Michael's lips directly.

Red-teaming science doesn't have to be a bad thing, but there's a lot of potential for damage here.

Professor Michael Mann pointed out at the 2017 committee meeting that this call for changing how science works was deeply biased.

Mann was the only one not proclaiming science to be broken, and he was the only speaker who didn't have a history of denying the consensus view on climate change.

Policies like red-teaming have a very real potential to exacerbate this issue.

So then I looked back even further still and I discovered this graph, nicknamed the hockey stick graph for reasons you'll see in a second.

It was plotted by a climate scientist called Michael Mann back in 1999 and it shows how the global average temperature began to increase exponentially as we moved towards the latter part of the 20th century.

2015 and 2016 were also heated even further by the El Niño effect.

I don't really know what El Niño is.

Now that they've been largely regulated out of shipping exhaust emissions and also reduced in many urban conurbations across the globe, the so-called aerosol dimming effect is diminishing, revealing the true extent of human-caused warming.

Others, like Professor Michael Mann, Professor of Earth and Environmental Science at the University of Pennsylvania, point to natural variability, particularly in ocean cycles like the ENSO system that we looked at in our previous video.

He and his colleagues highlight the fact that there have been two strong El Nino events since 2015 and argue that these events have caused a bit of a blip in the data.

The long-term trend since 1970 has basically not changed, argues Mann.

Now let's speak with one more expert to get even more clarity.

Michael Mann is Presidential Distinguished Professor of Earth and Environmental Science and Director of the Penn Center for Science, Sustainability, and the Media at the University of Pennsylvania.

He is also a co-author of Science Under Siege, so he is no stranger to the anti-science forces shaping the current political landscape.

If you've seen the famous hockey stick climate graph from the late 90s, that's his.

don't do that sort of thing here.

In an interview with the BBC, climate scientist Dr. Michael Mann laid out the stakes.

Now the focus has to be on minimizing the additional warming as much as possible.

The good news there is there is an opportunity just a couple weeks ahead.
