California Drought

[Eagle1]

What's the hottest Earth's ever been?

Can you posts links to graphs like that?

The best link I found was :
Global temperatures over last 24,000 years show today's warming 'unprecedented' but that is not NASA

I like your chart better, it has better links to sources.

The one I posted, showing similar data, came from this Reddit thread.

Like anything on Reddit, the comments following a post is where you often find better insight.

Some examples:

Climate change is what we see happening for thousands of years after the last glacial maximum.​

The more recent changes of the past two centuries are better described as a bomb going off.​

Taken from: The Raw Truth on Global Temperature Records – Climate Change: Vital Signs of the Planet​

...clues like ice cores and tree rings) provide scientists with context for understanding today’s observed warming of Earth’s climate, which has no historic parallel."​

​

There's also been like a 60% drop in wildlife in the same time period. The Holocene mass extinction is gonna be lit.​

​

Biomass of insect loss is a huge deal people are just ignoring.​

That last one is one I have noticed personally. Crossing a 10 mile swamp (Ca route 37) we used to splatter so many bugs on the windshield that we had to stop and clean up. Now, none! A very noticeable change.

@newbury The original chart is in this paper, though the temperature data comes from several sources.

(FYI: I used @California's original image to try and search site:climate.nasa.gov, with no hits, and then searched globally and found the Reddit image, which I then used as an image search in Google to find the above link.)

All the best,

Peter

There is no conclusive way to measure temperature prior to 1900. It's an estimate from a model. Models are nothing but assumption generators relaying upon tangent information.

It's amazing people think we can tell the temperature of the earth 5000 years ago.

There is pretty good science available today through proxies that have enabled us to do so not only on our own planet, but also others.

If by "science" you mean models...then you would be correct.

Always remember, there is no hard data...only assumptions.

Fossilized pollen is one way of estimating prehistoric temperatures.

Ancient Pollen Offers Clues to How Plants Adapted to Climate Change in the Past — and Potentially the Future

A new study finds that plants around the world moved poleward during a dynamic period of rising temperatures 56 million years ago

It's still a tangent metric to populate a model.

The best we can do to answer the burning question of past temperatures.. is generalizations.

Do I believe in climate change? yes, it changes every day. Do I believe man has changed the climate? a little. but not the doom an gloom that has been pushed daily.
