Reliable records don't go back very far into Earth's history, and modern temperatures are taken from incredibly scientific locations such as London's Heathrow Airport, so I take this claim with a pinch of salt.

There's proxies that give a decent local temperature. Estimates converge to within a degree.

and modern temperatures are taken from incredibly scientific locations such as London's Heathrow Airport, so I take this claim with a pinch of salt.

Local effects that impact a single measuring station are detected by difference in trend from nearby stations. If they are anomalous, then they don't contribute to the trend for that grid.

And measurements from satellites confirm that the ground-based measurements are not biased: https://www.woodfortrees.org/plot/gistemp/from:1979/plot/rss/offset:0.270847

Excellent links

Thanks!

Wood for trees is a good resource for mucking about with different temperature estimates. Note that UAH has a lower warming trend than the others, probably attributable in part to motivated reasoning by Christie and Spenser.

But RSS and UAH are both satellite MSU derived temperatures.

Fully fledged bullshit. This year was nowhere near the hottest year in my lifetime. Much less hottest on record. Those parroting this bullshit intend to enslave you.

This year was nowhere near the hottest year in my lifetime.

Perhaps you only experienced one location. This is the global mean surface temperature that is the hottest on record.

I think it was hotter during the time of the dinosaurs.

Generally, yes. There were periods during the Mesozoic during which there weren't any ice sheets at either pole.

A return to that climate would involve about 70 metres of sea level rise. It would probably be cheaper to try to avoid as much of that as possible.

They fumbled the ball on glaciers they contain less ice than was once thought: https://www.courthousenews.com/melting-glaciers-may-contribute-less-to-sea-level-rise-than-previously-thought/

I'll buy my EV when the rich climate changers stop using private jets and sea cruises.

Oh Whew!

One paper from last year estimates that the 5% of sea level rise from melting glaciers compared to ice sheets was overestimated by 20%. That means the total sea level rise is overestimated by as much as 1%, if this paper is correct.

So instead of about 70 metres of sea level rise, it may in face be only about 70 meters of sea level rice ... with the central estimate a little over half a meter lower.

Good to know!

I'll buy my EV when the rich climate changers stop using private jets and sea cruises.

Which rich climate changers are those?

If you don't drive much an EV might be more expensive still in the US. But for moderate to high usage cases, the minimal fuel costs offset the higher purchase price pretty quickly. But don't let economics stop you shooting your nose off to spite your face.

Earth has had the hottest year in record for the last 50 years, but in the history of our planet its all BS. They manipulate data to push climate agenda. Climate agenda is to kill billions of people and usher in total control. Read Klaus Schwabbs book "Covid 19: the great reset", or UN agenda 21 and 2030, and the "goals for sustainability"

If you know that the temperature history is incorrect, what is the correct one?

If you don't have a correction one, why do all the groups doing temperature history come up with similar results?

Actually....

It is the (biased) climate models, not the reality.
There are less measure stations, and the gabs are filled in with models that exaggerate the temperature.
And they use the stations close to hot cities and other hot objects without correcting for it.

Real climate scientists can inform you about it.

And there are other environmental problems.

No, these are measurements.

There are less measure stations, and the gabs are filled in with models that exaggerate the temperature.

The stations are used to estimate the temperature of each grid. Grids without any stations are treated differently by different groups.

GISS tries to estimate them. HadCRU ignores them and reports on the temperature trend of the rest of the planet. It means that HadCRU underestimates the temperature increase a bit, because the areas of the earth without stations are the poles, and they are warming more than average.

But they line up pretty well

I don't really get why we are still spending money on how fast we all are going to die from climate change; I'd prefer we first fund ways to make sure we don't boil to death and perhaps when we succeed in getting the temperature lowered by one degree we can return to the part where we talk about doom and gloom. Right now, since 1895 the science didn't change; it only got refined.

I really am starting to hate the summers myself. Imagine the hell it is in India.
