Global Climate Change Impacts in the United States

I was about to write about the new report by the US Administration titled “Global Climate Change Impacts in the United States” and was starting my research. I was happy to find that Climate Skeptic had already started to review the document. I may add some thoughts on a future post but for now I will recreate some of his statements here and point you to that site.

I guess I am doing a review of the review!  But I have done that before and it seems to be popular and provides a service to my readers.

Here is a rather long video that was released by the US Administration:

Is it too cold outside to have global warming?

There has been some talk in the press and on some of the blogs that it is too cold in the last couple years to have a global warming trend.  Some even say that the warming trend is reversed and it is now going to get colder.  There are a variety of people that discuss that the ice caps are re-freezing after having melted which signals that global warming is reversing. Some talk of a local low record that was set at some airport.

The reality is that much of this talk is about weather and not about climate.  It is not possible to measure climate within a couple year span.  It takes much longer than that to eliminate the various highs and lows from the trend so most climatologists suggest 5-10 years (or longer) before anything is really called climate.

Global Warming Chief Among Threats to Coral Reefs

Environment News Service – July 7, 2008

image The degradation of coral life has been happening for quite some time.  I remember multiple articles on the effects of water pollution on coral life back in the 70s and 80s (before the Internet so I can’t point to those articles – sorry).

This article now includes global warming in that threat.  Since this is coming from the 11th International Coral Reef Symposium and the organization reportedly meets every 4 years then the problem is at least 44 years old!

Is Your Global Warming?

GUEST ARTICLE 

By J Schipper

Carbon dioxide, the greenhouse gas linked to global warming, is accumulating in the Earth’s atmosphere at an increasing rate, according to a new study released by the US government’s National Oceanic and Atmospheric Administration. The research has renewed concern that the ability of the environment to absorb the gas may be waning. The NOAA study said the average atmospheric concentration of carbon dioxide in 2005 reached 381 parts per million, up from 2.6 ppm since 2004. The annual rate of increase, which has been recorded since the 1950s, now exceeds 2 ppm for three of the past four years. This is an unprecedented increase; 50 years ago, the annual increase was less than 1 ppm.

Reader questions – Part 1 of 4

I enjoy emails from readers of this site.  My contact information is in the About page and the comments and encouragement I receive makes this site a joy to run.  I recently received an email from Brittany C asking four questions.  Brittany is allowing me to publish her questions and my answers.  These answers are a combination of scientific fact with conjecture and opinion from me.

Question 1: Why is the warming that has taken place in this past decade been such a big deal when there seems to be a similar warming trend in the 1930s?  Is there a difference between the two? 

Great question.  I am going to break it up into 3 parts:

35 Inconvenient Truths: The errors in Al Gore’s movie – Part 1 of 5

Several days ago, I posted about RealClimate.org’s defense of the 9 ‘mistakes’ that a British court found in “An Inconvenient Truth” (AIT). My review was not well regarded by many at RealClimate as they defended their defense. My point at the time was that extremism is bad in all ways. Even if you think that the world is going to end due to human induced global warming, you must be able to see spin for what it is and confront it.

Conversely, if you think that all this global warming conversation is hooey, you still should not say that everything out of Mr. Gore’s mouth is biased and wrong. We need to evaluate each claim on its own and seriously discuss the viable issues.

Global warming melts Andean glaciers toward oblivion

Reuters – June 7, 2007

You will see different versions of this article floating around the internet.  This article discusses the major impact and hardship that will befall the people of Bolivia due to the melting of their small glaciers that are in the Andean mountains.  These glaciers are melting, so the story claims, because of global warming.

If you have read this site for any length of time, you know that some people believe a myriad of evils has been delivered on us (or will be delivered) due to climate change. I have written of several examples of this (here and here and here).  I don’t discount that these glaciers may be melting since the article gives us data to support that claim.  I also do not refute that this will cause these people harm – in fact, my heart goes out to them in their plight.

Extreme Weather: Once Every… Well, Every Day Lately

The Huffington Post – May 10, 2007

This posting from Laurie David discusses the weather that certain parts of the US has seen lately and points out that it is extreme. Ms. David is careful not to say that these extremes are caused by global warming although she does criticize the President Bush went to Kansas to visit the damage by recent tornadoes there while not implementing weather changing laws.

Ms. David is a very powerful political force in the conversation regarding global warming but not necessarily a scientific force.  I would be very interested if she would do an analysis to see if these droughts, storms, and warmest days are unusual or if the press is just talking about it more.

POWERFUL NEW TOOL TO TRACK ATMOSPHERIC CARBON DIOXIDE BY SOURCE

NOAA Magazine – March 21, 2007

This is fantastic.  NOAA has released a new diagnostic tool that will monitor the changes in atmospheric carbon dioxide and other atmospheric gases by region and by source.  This will allow users to understand the pollution that is being put into the environment.

In the above image “negative fluxes (blue regions) indicate places where uptake of CO2 occurs. Positive fluxes (red colors) indicate places where emissions of CO2 occurs. The figures include biological and fire fluxes, no fossil fuels.”

The online data framework distinguishes between changes in the natural carbon cycle and those occurring in human-produced fossil fuel emissions. It also provides verification for scientists using computer models to project future climate change.

Toward regional-scale modeling using the two-way nested global model TM5: Characterization of transport using SF6

Journal of Geophysical Research, Vol. 109 – October 12, 2004

I am not going to encourage you to read the source article.  I think that is the first time I am making that suggestion.  There are two main reasons:

  1. it costs $9 to buy it (and you can probably find a better way to spend your 9 bucks)
  2. it is a very difficult read.  I am not a meteorologist but I do have an engineering degree and even I struggled with this.  I know that I have several climate scientists as regular readers and I am sure they would understand much of the article but for the rest of my readers, I expect this is a little too deep.
