I can assure you that it was highly pushed in university teachings and was more widely accepted that what Wikipedia citings now say! I lived through it!! I have been a weather geek since keeping daily journals as an 8 year old child and I know what was being taught and hyped by many.

No ones doubting it was popular, but like most things, it was media driven (yes, like now with "global warming"). The data was never solid (pun?) Not saying its perfect now, but we have a much better picture of long term patterns and cause and effects.

Agreed!

Me too, im agree with you Canadianplant. They based their research on the ice carot from the groenland, and like that they can see that every time in the past the planet got warmer, they saw a brutal switch in the global climate patern. Cooling down the planet by a few degree, but they are not sure yet whats causing that. But they are focusing on the thermohaline current.
When the last ice age began to end, 10000 years ago, a lots of water from ther melting glacier over the entire Canada was stuck into a big reservoir (today the Great lakes are a vestige of that). And somewhere near -9000 years the reservoir emptied in, what is today the Hudson Bay, and all these cold fresh water flow into the arctic ocean and then the north Atlantic ocean. Thats stoped the thermohaline current. The gulf stream plunged further south, cooling down the Europe and all the Northern Emisphere for a decades.
Thats what we see today with the melting Groenland and Arctic.

Like i said, i hope they are wrong and all these 400ppm of CO2 in the air will moderate that brutal change if its happen 😉

Ben - You are refering to lake Agazziz. Probably one of the most important events in our history.

I don't believe any news article/scientist who claims they understand the climate system.........does anyone really think we will understand world climate change in our lifetime? If we understand climate change then why are we continuing to study it? 😕 We study climate change cause we don't understand it. 😀

Word! 😆

We will never fully understand anything. Yet we learn more and more things. And I have not read a single article saying any scientist claim they fully understand the climate system, or any field. I wouldnt believe those articles either.

I don t want to be obsess but there s another exemple thats something going wrong. The Europe cooling down again, in the end of march 😕 . Many place in northern Europe are well below average ,including UK and France. There s a ridge of hight presure siting over Groenland and perturbing the jet stream, we saw more things like that in the last few years....

I prefer the term climate change and in the spirit of John Lennon,I would take it another step
and say,"instant climate change"(is going to get you)....I have kept an open mind about global warming
and such but what I see happening is what we may call "the usual extremes" running almost on top of each other.

We may see the coldest March in history here this year and this directly following one of-if not thee-warmest
in history...last year we were around +15F over average(44/65F)and this year 21/36F,about -15F below avg(highs)
to see this happen (going from the warmest to coldest the very next year)is very odd to me.
Another figure to give some perspective-we saw a handful of LOW temps of upper 50s to 60F last
March-those were the lows! We have not hit 60F once this March and there is nothing in the forecast
to make me believe we will this March.

When you just average the numbers it adds up correctly because for the 2 years you come up pretty much
dead on average-but my feeling/worry is that mother nature is trying to correct an imbalance in the proportion
of warming in the mid latitudes by dumping huge amounts of cold air down...but there is also a lot of warmth going north
they call these patterns "blocking"but they are becoming somewhat random and frequent IMO like the planet
is having to go to extremes to balance temps....so it stops the "normal"progression and opens a valve to clear the excess...

Not an alarmist here but definitely not one to bury my head in the sand....unless its warm 🙂

The one blessing in this is that we did not have an unusually warm February where everything bloomed/leafed
out and was hammered this month but this pattern does look like a shift(back to cold) from the past 2 years or so of drought and
above normal temps(here at least)-it will be interesting to see what kind of summer we have here-will it be another cool one?????

I prefer the term climate change .....;

Thats the problem with saying "global warming". Sure there is a general warming trend, but it is warming all over. The weather patterns are changing if anything right now, which is bad enough in itself IMO.

I think you found a signature Jim! LOL

Geeezzz....we still under normal temp. after having a few days of normal temp. here in Montreal. Still have snow in my yard, but i can see some grass spots 😆 . All the eastern and central US and Canada are well below the average. Thats included the Europe too. And there was a big low sitting over greenland last weekend, it was a monster with a category 3 huricane winds, 200km/h, and huge from the newfounland,Canada to Portugal and from Greenland to the Caribean 😯 They rarely saw that before...Its -4c today and the normal high is +8c ...
Ben

Its -4c today and the normal high is +8c ...

Holy moly, Ben. 😯

Weird start to 2013 for a lot of folks.

Glad you can see some grass spots 😆 😆
We've mowed the lawn twice...

what's the strongest indicator of a warming planet? I tend to 'believe' sea level the most. I'm not so much a 'believer' in global temperature or ice extent accuracy.................perhaps sea level is not accurate either? The global sea level appears to be rising; therefore, the global temperatures would be rising as well. I'm not seeing much evidence of a cooling planet yet...............I really want to warming to continue. 😀 I can only imagine sea levels are heading back to where they peaked in the recent past (another 10 to 20 feet higher in elevation). The only question is...........how long will this take?:?

Global sea ice area is technically 'above normal' but the arctic summer lows seem to be trending down still.

Global temperature data is all over the place.....not too confident in it's measurements.
