Or is it the Excess cosmic rays? by kernick

Do the GW models of the climate include the methane mentioned above. Maybe; but I doubt they include things like the following.

What effect does this extra radiation have on heating the atmosphere or ionizing it and creating chemical reactions in the air?
 
Oh how little we understand, and yet Mr. Gore and his paid-for-scientists would have you believe we must drastically change our lifestyle.

I would think NOT, as the examples you mentioned are NOT sound bite able and are normally relegated to fonts sizes less than the fine print on those sped read advertisements. and as filler. Conversely, they are sensationalized on rags like the National Enquirer, probably as a follow on to articles like: "The Aliens After They Abducted Me, Let Me Drive Their FLYING Saucer".

Global Cooling signs here in NE by kernick

Not only are the air temperatures been really cold around here (which could be discounted as weather, and not climate), as expressed in the following article; but the ocean temperatures which are far harder to change because of their mass are colder than normal.

And it is only Fall! The only people who like winter are the skiiers and plow-drivers; so I say again let's forget about keeping the Earth this cold.

So how did you know I was the former and not the latter? They did let me drive an Oshkosh once! MORE POWER !!!
 
We are able to drive up to the snow SKI and drive out of the snow,( in as little as 2 hours: Actually 4 hours) The 3 or four total winter seasons I have so called LIVED 24/7 in the snow was enough to last my lifetime, and I was dragged kicking and screaming to those. ( for 2 years, I was stationed 90 miles south of the Army's Artic training Headquarters, 10th Mountain Division- USA's version of Siberia?) Watching your car rust in front of your eyes was not my idea of fun.

Me too, but I only have to drive about 30 minutes to get to the snow.

Does This Sound Right? by oldfarmer50

I heard yesterday that all the Hybrids that Toyota has sold have been sold at a LOSS!
 
How can that be? Why would Toyota sell a car for less than it costs to produce?
 
More importantly, why are other car companies producing hybrids at all?
 
I guess it does make sense in a Global Warming Cult sort of way. Put yourself out of business so there are no more cars and then the planet will be happy. Just don't fall down and break your leg or it'll be a long hop to the hospital.

I also sometimes peruse the Prius maintenance sites. I was literally shocked to see how the hybrid ICE is engineered for LOW (OCI's) oil change intervals- like the dirty old gassers of old (LEADED and unleaded) , aka 3,000/5,000 miles.
 
I wondered how much MORE it would cost (R& D total, per unit cost, etc.,) for them to respecify and obviously redesign the hybrid engine to go a min of 10,000 miles between OCI's; like say, the Honda Civic. This of course is 2x to 3.33 x better for the Civic (conventional oil by the way) !!
 
I personally run OCI's of 20,000 miles on Mobil One 0w20 to 5w20, and have so for 76,000 miles Oil and the next 20,000 miles oil, and oil filter change is due 80,000 miles. It is totally sludge FREE !!!! The thing runs like a top. I run the VW Jetta TDI 20,000 to 25,000 miles OCI's, again on a Mobil One product (Delvac One/Mobil One Truck and Suv 5w40)

I think Toyota got burned pretty good on their sludge (pardon me, gel) issue and shortened their intervals, at least for the North American markets.
 
Oldfarmer, I think the Prius may have been a loss leader for a year or so, but not after that.
