«sea levels are rising» They are since we
got out of the last ice age 20.000 years ago when the sea is 130 m below the current level and when carbon emission was not considered a problem.
Jim D: The rate of temperature change now is a hundred times faster than the rise out of the last Ice Age
But, he said a temperature increase of that magnitude was enough to bring the
world out of the last ice age, and it will be enough to «radically transform» the Earth's surface in the future.
Several studies have shown that around 10,000 years ago, as the planet
came out of the last ice age, vast portions of volcanic summit cones collapsed, leading to enormous landslides.
[Sea levels] are [rising] since we
got out of the last ice age 20.000 years ago when the sea is 130 m below the current level This is a very weak argument.
These changes include the gradual warming that brought
us out of the last ice age, the fairly recent transition from the Medieval Warm Period to the Little Ice Age in Europe, and the recent 1991 Mount Pinatubo eruption that measurably cooled the atmosphere for a brief period.
For example, we are warming far too fast to be coming
out of the last ice age, and the Milankovitch cycles that drive glaciation show that we should be, in fact, very slowly going into a new ice age (but anthropogenic warming is virtually certain to offset that influence).
Things had been warming up
out of the last ice age, starting about 15,000 years ago.
I remember an article in SKS where it was stated that the orbital forcing did not explain the warming coming up
out of the last ice age.
