Yes, everyone knows that we are living in special times

The only time that matters is 1880-now. Or 1980's - now. Depending on how alarmist one needs to be.

Ah, good to know. What about the other 4,499,999,960 years of the planets history?

Humans weren't alive in the majority of them.

It's not naughty, it's just irrelevant. Unless you think comparing something that may or may not have happened to the climate over the last 250 years to times 4.5 billion years ago when the earth's atmosphere was 10% methane, 0% oxygen and with no multicellular life on it is useful?

Yet we still evolved and only recently are we not subject (survival wise) to the whims of nature. This rock has a limited time span (either through CO2 starvation - sea life will ultimately lock all the free carbon away or though solar death) - ice ages are likely to return so we better get off our asses and start populating the cosmos or it will be the end of us.....

Not sure if this article has been posted, seems to be a worthwhile read-

OK, then how about a chart of the last 315,000 years, or so? Bottom line is our in depth knowledge of the Arctic Sea ice extends back to the 1970s, that is about it.

Apparently the sun has quite an effect on the Earth's climate who'd have guessed?!?!

Great article on Arctic sea ice here from JPL- https://www.jpl.nasa.gov/news/news.php?feature=725...

And after the big anouncement about doing something immediately to curb climate change on the news, today the ruling to start fracking
For more fossil fuels has been anounced
After the campaigners have lost there court battle, so just as we thought more taxing of the public and also now taking away subsidies for
So called greener vehicles,
If they ever want anybody to take climate change seriously I think they have fked it

Climate models found to be wrong, don't match up with actual observations-

What was it like 200,000 years ago ish then just before humans arrived?

TX.

Apparently they didn't have an answer to that, so just let it drop?

TX.

Which has nothing to do with the actual problem.

A warming planet 200,000 years ago isn't going to lead to increased chances of extremely expensive flood events in coastal towns and cities, for example.

Have you definitive proof that a rise in CO2 increases the events of flooding ?

Err, I would say it's pretty certain a rising sea-level brings an increased risk of flooding.

My question was regarding the link to a small addition to a trace gas in the atmosphere .

In fact, PRTVR, I would say there is currently data directly contradicting that hypothesis (that CO2 will cause watery Armageddon).
From data at psmsl.org of the two longish-running UK sites:

Let's not even consider all the human settlements and constructions that have been submerged for thousands of years eh...

Yes, how many UK coastal villages have been lost to rising seas over the last couple thousand years?
