Changes in Atlantic currents

The last glaciation was prior to the start of that data set.

The 6000 year cooling from the Holocene Optimum is clearly visible as is the abrupt reversal of the cooling at the start the Industrial Revolution.

So who's right and who's wrong?

When you say America are you referring to Etas Unidos or are you referring to Canada which many call America light? Or are you referring to any of the many countries in the western hermisphere?

It seems your bottom graph is demonstrating what is occurring. Relative to the last million years, the recent rise in CO2 and temperature is dramatic. It is not relevant to compare the Earth and its climate from those times when it was dramatically warmer. Life in those times was adapted to those conditions. We are not. The changes in temperature and climate that occurred too quickly for life, no matter when they occurred, cause major die-offs and extinctions. Those concerned about climate change right now are just trying to avoid another one. And we aren't doing too well.

Mate, you’ve missed the fact the graphs were on different timescales.

The left hand graph says the United States.

The only major land mass not natively inhabited by homo sapiens is Antarctica. Other than that, we seem to have adapted quite well to a variety of environments. And if you want to observe real dramatic changes in climate and temperature, hang around in high latitudes for 6 months starting December 31st.


The one commonality between any graph of historical global temperatures is that the climate has never been anywhere near close to flat-line stable in the entire history of the planet, regardless of the use of sneaky exponential X-axis graphs. To think that it has is pure fallacy. In fact, in the past 600e6 years of complex life forms, the majority of mass extinction events have been associated with glaciations.

The bottom graph is from
https://www.newscientist.com/article...to-our-planet/

and is based on https://link.springer.com/chapter/10...-319-46939-3_1

What is the source of the first?

This is when you apply this test:

Sure. Just let me know what my assertion is.


Is it your graphs that don't correspond with those produced by geologists?


Is it your temperature graphs based on homogenized data?


Is it your claims that the US temperature (pre-doctored) graph was regional only?


Or is it Tim Wirth's on the record confession about opening the windows of Congress the night before the 23rd June 1988 as all a hoax?

Does the Geological Society of America do it for you? Or are they on the Desmog list?

I apply the test myself. Your posts are abject failures.

Are you familiar with this concept?

Not to be pedantic, but check out the peaks and troughs at comparable periods.

So is that a yes, no or dodge?

To refresh your failing memory - you accused me of revisionist history
