Arctic Sea Ice Extent

Arctic Sea Ice extent continues to be a problem. This year, according to the National Snow and Ice Data Center, ARctic Sea ice reached its lowest extent this year on September 17th, which is about the sixth lowest extent on record, following a multi-year trend of decline. There is variation from year to year. This…

Some time in the 1970s. I keep hearing about this 17 year long pause in global warming. So I went and looked. I did a regression analysis of the last 17 full years of surface temperatures from the GISS database. There is an upward trend in warming during this period and it is statistically significant.…

What can we do about climate change?

I could rephrase this question. What should we do about climate change. The reason I might rephrase this is because we may not ben that sure of what we can do, but we should do something. Or, more accurately, some things. There are a lot of possible things we can do, and we have little…

The Eye of the Storm, And The Storm

There has not been much hurricane activity in the Atlantic for a while now, so unsurprisingly the reporting is starting to slip again. This post goes out to all you reporters at CNN and Reuters and Yahoo and everywhere else. Imma give you an example of what you are doing wrong, then I’ll send you…

Mark Steyn and Judith Curry

Two items related only because these two seem to like each other and there are coeval happenings. Mark Steyn and Dr. Michael Mann’s book Michael mann wrote a great book called The Hockey Stick and the Climate Wars: Dispatches from the Front Lines. It really is a good book, I highly recommend it. Mark Steyn…

Atlantic Hurricane Gonzalo is a Major Hurricane, Category 3 at the moment, and it is heading towards Bermuda. The storm will weaken a little bit before getting there but it will still be major. This is a significant event. It is possible that a storm surge of about 10 feet could occur there. Gonzales will…

Official Prediction of US Winter

The National Oceanic and Atmospheric Administration (NOAA) has released its official prediction of what this winter is going to be like. And yes, it is in ALL CAPS!!! I’ve pasted it below, but first a summary of the relevant points. According to NOAA El Nino There will be a weak El Nino, late Autumn or…

We have been having a run of very warm months, and according to the GISS database, updated yesterday, September was the warmest on record, and the records go back to the late 19th century. This is global average temperature of the surface. I’ll have more about this later, as other databases are updated. Sometimes one…

Antarctic Sea Ice and Global Warming

Did you ever leave your freezer door slightly open on a humid day only to find chunks of new ice formed at the gap? When that happens, did you conclude “Oh, my freezer is colder than usual, I wonder how that happened?” No. You concluded that you had left the door slightly open, some cold…

What is the role of the ocean’s abyss in global warming?1 I’ve already posted on a study published in Nature Climate change that shows that the amount of extra global warming related heat in the Southern Oceans is greater than previously thought. There is another paper in the same journal by Llovel et al, “Deep-ocean…
