@Kenneth72712993 – A new tropical Atlantic subsurface temperature reconstruction indicates it was 7°C warmer than today during the Younger Dryas/Bølling-Allerød (~15,000-11,500 years ago), when CO2 concentrations hovered around 210-220 ppm.
Paper is here.

In related global warming scam news, our environmentalist prime minister is burning jet fuel to Bracebridge Ontario today for a community barbecue. I’m sure he will be warning the peasants about climate change and encouraging people to cut down on their travel plans.
at 200 ppm we start dying.
Could that be a enviro-nutter plan?
We’re at 400 ppm CO2 right now. I gave up “debating” greenies on CO2 levels log ago. I just ask them “If 400 ppm is too high for you, what level do you wish CO2 to be?”

Well its Ramadan so lets pump up the volume on the killings, inshallah.
Unfortunately the UN and all their pliant stooge Governments like Trudeau and Canada have pledged Trillions to fight Global Warming.
And they are trying everything they can to censor Researchers like Prof. Valentina Zharkova, who using latest research and satellites to measure actual solar magnetic fields is saying we are moving into a protracted cooling cycle with the sun.
A Solar Grand Minimum perhaps deeper than the Maunder Minimum. What she is saying is that the Sun and solar cycles is what controls earth temperature. They do not like this and have even threatened her.
Better wake up folks. She has a 80-90% accuracy rate with all her work so far. She is predicting food shortages beginning in 2028, if she is right, grain growing regions of the earth will shrink back below the 40 deg lat. in the northern and southern hemisphere. There will be no grain for Africa etc.
Civilizations have risen and fallen with the solar cycles. The Chinese actually documented it in their history. Grand Solar Minimums bring disease and wars and famines. Wars over resources. All the great Migrations in history happened during Grand Solar Minimums. The French Revolution was sparked by food shortages in the Maunder Minimum. Read about the Year Without Summer in the US.
The crop cycles are all disrupted by highly variable weather patterns due to the changing ocean currents and wind patterns. Areas that have drought become wet, areas that are wet become dry. You have unseasonable weather highly variable weather patterns and it is all driven by the sun. https://wattsupwiththat.com/2016/08/09/solar-physicist-sees-global-cooling-ahead/
The NASA satellite SABER which measures the Upper atmosphere is saying that the earth is cooling and could get very much cooler. Does not jive with the AWG Fraud so is being suppressed by the State Media, it interferes with the anticipated 90 Trillion that Western Nations have agreed to pay the UN under the Paris Accord. At a time when governments should be warning people to prepare for food shortage and chaos from cold weather and highly variable weather that disrupts food production, the have lied for so long and spent Billions of Tax Dollars reducing CO2 that the populations are going to be in shock. DO YOUR OWN RESEARCH YOU ARE ON YOUR OWN. This is why they are suppressing alternative science that proves them wrong.

The Younger Dryas was an actual, short-lived (1,300 years) ice age that resulted in substantial die-offs among large animals. The idea that tropical sub-surface sea temperatures were warmer than now seems absurd on its face.
It was caused by disruptions in ocean currents caused by the massive melts of freshwater glaciers so it doesn’t strike me as particularly strange that ocean temps were perturbed.
A bit off topic

Do you agree with the call for Canada to cut its greenhouse gas emissions in half by 2030?
Need support.
No is winning big time now.
