Research links climate change patterns to El Nino

I found this study by reading the blog at AccuWeather.com.  If you are interested in climate, then you should spend time reading what the meteorologists over there have to say.

A study by 3 researchers and published in the Journal of Geophysical Research has concluded that the weather variations (both increases and decreases) are the result of natural climate processes. They find that the Southern Oscillation is a key indicator of changing global atmospheric temperatures seven months later.

The paper is titled “Influence of the Southern Oscillation on tropospheric temperature” and following is the abstract:

Powerline graphs – how about some background?

Powerline is a very popular blog and forum for those that follow a conservative movement within the US. I am sure that their membership measure many multiples over this site.  Therefore, I am hesitant to be too condemning of one of their recent posts but I need to talk about it a little bit.

To their credit, they encourage readers to go to the original sources to get the complete story but, frankly, that is not good enough.  They have published the information in a way that is incredibly one-sided and is also not consistent from one chart to the next.  That is the true problem with the article, one cannot see the filters or data sources in this presentation so the inconsistencies are too strong.

A lot of talk about George Will

I would never have expected so much discussion regarding George Will when it comes to global warming. While he is incredibly intelligent, he is hardly a person that one would describe as being an expert at global warming. It is amazing that when this political commenter says, “Real calamities take our minds off hypothetical ones. Besides, according to the U.N. World Meteorological Organization, there has been no recorded global warming for more than a decade, or one-third of the span since the global cooling scare.” and the comment results in multiple articles and arguments from scientists and laypersons about how he is wrong.

Scientists find bigger than expected polar ice melt

There is no question that our climate has changed slightly compared to 20 years ago.  Most of the data points to increases of temperature and the most significant (and obvious if you are in the Arctic) is the diminished amount of ice in the Arctic Ocean.  While there is some question as to the cause of this melting (see my ocean currents article), there is little question that it is occurring.

This article discusses some of the observations that scientists have seen regarding the ice melt and some possible repercussions.  The article is somewhat refreshing though in that it focuses on what can be observed rather than focusing on what might be causing the warming.  Since it was so evenly reported, I felt it was of significant interest to my readers.

NASA satellite searching for global warming clues crashes near Antarctica

It looks like we are going to have to wait for awhile now for better data on what is really going on with our atmosphere and climate.  The satellite that NASA sent up to study the flow of carbon dioxide developed technical difficulties and crashed.

Once again, we see that our ability to travel outside of our world is still quite experimental and we struggle to do it with the repeatability of plane flights.  If I was a conspiracy fearing individual (which I am not) I would question if scientists deliberately sabotaged the flight so that real data that could prove or disprove climate models could not be gathered.  Such speculation is obviously foolish though.

NASA Prepares to Launch Satellite Designed to Study Global Warming

This is absolutely wonderful news.  There is no question that we don’t fully understand the complexities of our atmosphere.  Our models which predict doom and gloom are woefully inadequate (which doesn’t make them incorrect – it just leaves room for extreme doubt).

Perhaps this study will solve one of my mysteries in the global warming discussion and that is that North America actually appears to sink CO2 rather than emit the gas.  We know that carbon dioxide is increasing from man’s efforts due to the isotope nature of the CO2 in the air but we still struggle understanding how CO2 spreads through the atmosphere.

Scientists flip-flop on Antarctic melting

I originally found this opinion in “The Detroit News” and so you can click through and read the entire article.  I really cannot explain this topic better than Mr. Taylor and I suggest that you read my highlights here and then read the full article if it is interesting to you.

Understand that Mr. Taylor works for the Heartland Institute which is known as being pretty close to the edge when it comes to rational discussion on this issue.  However, even people with extremely strong feelings on an issue are not totally wrong and need to be listened to. 

Ice melting across globe at accelerating rate, NASA says

CNN – December 16, 2008

This story about the rapid melting of ice in the major cold areas of the world (Greenland, Antarctica, and Alaska) needs to cause everyone concern. While the story doesn’t convincingly discuss the causality of the situation, it does point out that increased melting accelerates the planets warming due to loss of reflectivity of the “white” ice.

The article goes on to point out the increase of pine beetles which is theorized to be attributed to a warmer environment. It even goes so far as to predict the increase in sea level (ala Al Gore) by the end of the century based on this loss of ice.

In Science, Ignorance is not Bliss

Launch Magazine – July/August issue

Walter Cunningham is one of the astronauts of Apollo 7.  He writes about global warming in the latest issue of Launch Magazine and his comments bear considering.

Mr. Cunningham is important in this discussion because of his obvious intelligence and past leadership but also in his strong ability in analyzing scientific and political events and drawing conclusions.

What I find to be most compelling are:

  • his ridicule of climate models.
  • his discussions of correlation and causation.
  • the replacement of scientific discussion with emotional arguments.
  • the condemnation of Mr. Hansen – one of the early warning voices of global warming and an employee of NASA.

Antarctic ice shelf ‘hanging by thread’: European scientists

Breitbart.com – July 10, 2008

image This is quite concerning. Most of the instability in the ice shelves in Antarctica have been during the summer.  Now it appears that this shelf is in danger even though the continent is currently undergoing winter.  There have been a rash of shelves collapsing and Nobel Prize winner, Al Gore, spoke of this in his film “An Inconvenient Truth”. It is not conclusive why ice shelves collapse but it is important for us to explore these situations.

It appears that this shelf is being “eroded” underneath by warm waters.  This is likely the cause of the rapid failure of the other shelves as well.  Interestingly, some of the other shelves exhibited water pooling on the surface before their collapse but there is no mention of this situation in this article.
