Arctic ice cap growing again

Solar activity is something else which also affects the earth's climate. (For example, where I grew up, the annual rainfall peaks with the 11 year sunspot cycles. During a peak year in sunspot activity, 97 inches of rainfall in just a three month period is not at all uncommon).
For those who are interested, though, the following discussion outlines why it is thought that the current warming trend is not the result of increased solar activity.

Sea Breeze,
Not sure why that article you quote includes a link to NASA, because if you follow that NASA link, it mentions nothing about Arctic sea ice being greater in extent in 2021 than in 2007? Rather, it confirms that the area under sea ice in the Arctic (as measured each September) has consistently decreased every year from 1979 until the present.

In 2021, the Arctic sea ice extent was 4.72 million square kilometers, about 11 percent more than the 4.16 million kilometers in 2007, according to NASA’s estimates.
Facts are irrelevant to true believers on the far right, the far left or any other dogmatic belief system. This site is no longer a forum interested in uncovering truth wherever it may lead. Users can't even post questions that would lead to a forbidden conclusion. About the only good thing here anymore is Atlantis posting info that is otherwise unavailable.
Rivergang, looks like some one changed that quote or got their facts upside down. Thanks for pointing that out.
Here's a NASA link that says Artic ice reached a maximum record just 8 years ago. Looks like a lot of flux.
Sea Breeze, reading isn't your strong suit is it? Try reading it again, the whole thing. You do know there is a difference between the Arctic and the Antarctic don't you?
There has been considerable speculation about the role of volcanoes in the release to the atmosphere of greenhouse gases.
Going by the example of the Mt Pinatubo eruption (Philippines, 1991), the short term effect of a major volcanic event is to in fact cause lower temperatures. That volcanoes release large quantities of sulphur is self-evident to anybody who has ever been in a volcanic area (For example, the city of Rotorua in New Zealand's Volcanic Plateau, throughout which the "rotten egg" smell of hydrogen sulphide gas permeates everything!).
This results in an "aerosol" of fine particles of sulphuric acid in the atmosphere, which reflect the sun's rays - see the following link to a CSIRO discussion about this effect, and the result it has on surface temperatures.

Sea ice and land ice are two different things. Land ice in Greenland and Antarctica is decreasing steadily at increasing volumes.
Vidqun,
Really?
What scientific back up has the cartoonist got for that statement?
