Africa, Drought and Global Temperature

I have seen a large number of discussions recently about droughts and how they will be getting worse with a warmer Earth.  This of course is based on the Global Climate Models (GCMs), that were created for the purpose of showing that CO2 emissions, will cause the Earth to become nearly uninhabitable, if we don’t […]

Seasonal Temperature Across the Whole Atmosphere

Since last week’s article generated a lot of interest and requests for more information, I decided to write a follow-up on the previous article. The point of the article was to demonstrate that the seasonal temperature response varies by altitude. So different are the responses that it is clear that the troposphere and the stratosphere are responding to different inputs. The temperature of the troposphere is primarily driven by the combination of geography and season at the Earth’s surface. The stratospheric temperature is driven by the daily energy the Earth gets from the Sun as dictated by the distance the Earth is from the Sun. You can look back at the previous article for more details.

A Tale of Two Altitudes

Any serious discussion about the Theory of Global Warming will eventually include the absorption band argument that started more than 100 years ago between Arrhenius and Ångström.  One of the arguments presented by Ångström was that the main CO2 absorption band is between 14-16 micron and that band is also absorbed by water vapor (which […]

Flagrant Attempt to Mislead the Public about the Holocene Onset

As I noted last week, there is a new article in Nature that tries very hard to prove that CO2 increased prior to the warming at the onset of the current interglacial which is known as the Holocene. I read the article and was stunned by the conclusion and the charts which clearly showed that the warming took place after the CO2 rose. Since I have extensively studied much of the available data from the period 10-20k years ago, I knew right away that this paper did not give the same conclusion as any of the other data.

Norway Experiencing Greatest Glacial Activity in the past 1,000 year

One of the main points that I have been making on this website and in my book is that the Earth was much warmer 6,000 years ago than it is today. In the book I point out many examples of glaciers that have only formed in the past few thousand years. I am always looking at new data as it becomes available and recently there was a nice study in Quaternary Research that did a study on glacial activity in Norway for the past ~8,000 years.

9th Hottest Year?

Over the past week I have seen news articles all over the place that 2011 was the 9th hottest year ever recorded. Not only that, but 9 of the 10 hottest years are since the year 2000. The NASA news release (GISS) is the main source for this statement, but it has been everywhere. Press releases like this are really good examples of irrelevant arguments, while being misleading at the same time.

Seasonal Arctic Freeze has Begun.

One of the NOAA Arctic webcams has survived the summer months and is still providing pictures. The camera is at an odd angle which is likely due to melting that took place on the ice. It has been that way for at least a month and the picture shows more instruments at odd angles as well. The NOAA placed two webcams in April and they also make videos that can be watched on YouTube.

A few thoughts on the drought in Texas.

I had previously noted that that the Pacific has developed a cool phase of the Pacific Decadal Oscillation (PDO). I have been suspecting that there is a correlation between the two events. My research has made clear that the oceans cycles dominate the weather on the land and this should not be an exception. My region has had a cool and moist year on average and Texas has had the opposite. In looking around I found this for a warm phase PDO.

Curious about the latest CO2 Paper

The recent presentation by Dr. Murry Salby is getting lots of attention. I have now listened to his podcast and I must say it is intriguing. Instead of rehashing discussion that has been done to death on other sites I am going to show some things that I found previously that tie in well with his paper. I didn’t understand what I found at the time, but now it is clear that what I found actually supports what he is proposing. That human emissions have almost no impact that global CO2.

When I was working with the sea level data and the acceleration rates for the sea level I also used that same method on temperature and CO2 level. Acceleration is the rate at which the rate is changing. Acceleration is zero if the speed is not changing. When I used the same method for determining the acceleration for temperature I ended up with this result.

What is going on in the Pacific?

The Pacific Ocean is developing an interesting pattern that is different from the more well known El Nino/La Nina cycles that officially go by ENSO. Instead a very powerful cool phase of the pattern known as PDO is developing. The PDO was last in the cool phase back in the early 1970’s. Since then it has typically been in what is called the warm phase. I have compared the current pattern to the available records that extend back to 1998 and I cannot find anything that even compares to the well defined nature of the current ‘cool’ PDO.
