The current models do a pretty good job of describing the trend over the last couple hundred years, which is why there is confidence in their ability to predict the future. The models do not describe the trend of the last couple hundred years, the data from the last couple hundred years was used to...

Dear apodman , I agree many amazing things have been accomplished, but an ice age repulsed? Now you are an optimist of the highest order. I would bet a substantial sum (not huge, just enough to make it sting) that the sun is the major factor in ice ages by far, second would be an orbital factor. And...

Dear Dr Skeptic-If AGW exists and plays any role in our climate, ice age is to AGW as F5 tornado is to trailer park. The is no comparison of the forces involved. We couldn't moderate an ice age under any circumstances, we can only move out of the way. I'm thinking Venezuela (post Hugo).

For anyone who would like some insight into sea ice physics, Peter Wadhams covers the subject for my purposes and there's no urge to lash out after you read it. http://www.arctic.noaa.gov/essay_wadhams.html

The concern about GreenHouse Gases comes IMO from studies of Venus. Venus is very similar to earth in size and gravity. So the concern of GreenHouse Gasses on Earth comes from the fact that Venus can not sustain our type of life. Both Venus and Mars have atmospheres containing more than 95% Carbon ...

Here are the last 3 years indicating Snow Coverage (2005 feb is missing, 2004 and prior don’t indicate snow coverage) BMAONE23-So why in the 1998 image is Greenland white? Bill The white area in Greenland is residual Ice Cap as opposed to annual snow cover. So, whats up with the western mountains i...

My conclusion after much study is that anthropogenic global warming is a taxing strategy for the elites. I think a lot of bigwig scientists need that grant money. I don't think the human race is competently capable of adjusting the earth's thermostat. The idea of dumping iron in the ocean or burning...

BMAONE23- Thanks, better images than I hoped for. Very interesting. Sea ice is less in later years compared to 1998. But, wow check out the snow cover, last Feb and this almost normal. High albedo, heat reflected out, dare I say cooling. Check out the solar scientists it is sobering. Bill

Why don't you show the current image instead of the summer image?

I am not sure if we are looking directly at a cloud or its refllection. I vote for cloud. In South India at sunset I have seen clouds directly overhead, significantly redder than APOD, such that my surroundings were bathed in red light. The reason was my position at the tip of the Deccan Plateau cre...

IRT Chris Peterson, Argue the facts Chris, don't call names.

I'm not sure what this APOD has to do with astronomy. I've noticed that you have very few pictures of the spotless sun recently on APOD. It is probably THE environmental story due to all of its inplications.This is perhaps more topical as the peak average temp of the earth was in 1999 (I meant to sa...
