When they say where's global warming, they can't see it above the atmospheric noise

We finally got some winter. Seems like Bellingham winters have been a bit milder than normal over recent years. This is more normal. We get a hard winter every few years.

Some people might ask where's the global warming? Here's my reply.

So far, global warming only accounts for worldwide average temp rise of around 2 degrees C since 1900. It can still be snowy in the winter, but I think cold years are getting less frequent in this area. Over the long run, most glaciers are still retreating, precipitation patterns are still changing, growing seasons are still getting longer and sea levels are still rising. It's subtle so far and often still buried in the noise of normal weather variation from day to day, year to year.

Some models predict that there could be more of a temperature rise by 2100. More than just around 2 C. More like 4 to even 8 degree rise. That would really be serious. The situation could be accelerating due to population growth and growing prosperity; especially in developing nations. Also there's talk of feedback effects with methane and so forth. Hopefully these predictions will not come true. We can make some changes.
