This summer has at once been the hottest ever and yet absolutely awful. Climate change is a hoot.

99% of climate scientists believe in global warming Julia, you're wrong on this one and (god help me) Lewis is right.
-
What’s “believing” in something got to do with anything? We’re discussing FACTS.
-
100% of people making this argument prioritise tedious "gotcha" pedantry over genuine debate

I wonder what the odds are on the last 5 years being the hottest in the last 139 by random chance alone
-
That sounds about right. I’ve never found political views based on 52 billion to one coincidences particularly persuasive. I’m going for
@lewis_goodall over@JuliaHB1 on this one I think. - 1 more reply

Why are so many Pro-Brexit people also Climate Change Deniers? Is that causation or correlation?
-
I guess you're going to find a lot of correlation because both positions involve a great deal of wilful ignorance and delusion, while offering unwarranted comfort and unearned hope. The underlying skills are readily transferable, and it confers a big temporary benefit.

Wouldn't you feel so much better if you could convince yourself things were actually going pretty well? We weren't facing massive worldwide existential threats, the ecosystem wasn't collapsing and going to take us with it? That leaving the EU will improve our lives? I would.

When was the atmosphere last at 400ppm CO2 Julia? ~3 million years ago. Mid-Pliocene. SL was 15-25m higher and air 2-3Cdeg warmer. RATE and AMPLITUDE innit. https://e360.yale.edu/features/how-the-world-passed-a-carbon-threshold-400ppm-and-why-it-matters … https://climate.nasa.gov/system/resources/detail_files/24_co2-graph-061219-768px.jpg …pic.twitter.com/v8R5LxZ6W4

Science gives us ways to measure the climate over millions of years, Julia. The last time it was this hot was 125,000 years ago.
-
Let's be accurate; we have ways to estimate temperature. We measure proxies for paleo-temperatures and hope there aren't too many confounding factors.

Wouldn't we be expecting this sort of thing at the moment? Aren't we on the peak of the rebound since the last ice age?pic.twitter.com/ONMv7f0oqE
-
depends what you infer from the graphs - over the 5m year range there's an overall cooling trend but increasing hot/cold variation. The 800k year one shows clear periodicity but variability in each cycle. Timescale is key - the current speed of change may be unprecedented
-
Yes I appreciate the scale is rather long term. I suppose we have to view these things within the human life scale
-
We should certainly be concerned with years/decades and ideally a few centuries. Assuming that it's a far distant problem for our descendants to solve will make it more difficult

Haha Julia handing Lewis his arse this afternoon

-
No, just demonstrating that she’s not up to speed with reconstruction of historical climate data from ice cores & other sources. You are welcome to your own arse on a plate, Ms Thomas.
-
You sound somewhat triggered
perhaps you need to surgically remove your own head from that sizeable shit-filled iceberg it's stuck inside? And it's MRS.....ta

I pity the "mister"
