According to a new doctoral dissertation at Stockholm University in Sweden, based on analyses of deposits of pollen grains, it is possible that all of Sweden was virtually free of ice for long periods during the latest ice age. The findings show that the glaciation might have started some 20,000 later than was previously assumed... The size and movement patterns of the ice sheets can be calculated by studying land forms and moraine deposits... Martina Hättestrand's dissertation is based on studies of pollen grains that were deposited more than 40,000 years ago in small lakes during the ice-free phases of the latest glaciation. During the warm phases of the Ice Age, high amounts of birch pollen were deposited, which indicates that summer temperatures were around 10 degrees centigrade in northern Sweden. During cold ice-free phases, mostly grass and herbal pollen was deposited... According to the previously accepted hypothesis, Sweden was covered with ice 75,000-20,000 years ago. Martina Hättestrand's hypothesis, on the other hand, is that Sweden may have largely been ice-free between 59,000 and 40,000 years ago. If this is true, the last ice sheet of the Ice Age formed much more rapidly than was previously believed in order to have reached all the way down to northern Germany during the maximum phase about 22,000 years ago. The latest Ice Age is called the Weichselian glacial (glaciation) in northern Europe. It started roughly 120,000 years ago and ended about 10,000 years ago. The definition of an ice age is that it has a colder climate than an interglacial period, which is the type of climate we live in today. The climate varied a great deal during the ice ages.

Everything remains conjecture...These time spans are huge and they occurred naturally. The idea of “global warming” being caused by man is a farce...It’s calculated on miniscule hypothetical data....and makes no room for every other force in nature. Sometimes, man is just plain dumb.

God dag Pojke. Vilja till Gå och både?
Is global warming caused by human activity?

Burrrr. Shudder, Shiver.
I don’t see any bikinis.
LOL, you're right.
I grabbed the wrong pic from google images.
You’ve heard of Freud?
;-)
And the bottom.
The source advocates AGW.
That’s the agenda of a lot of people (not me of course), but it’s also the rationale for funding a lot of research — none of which ever supports the AGW claims.
