US Drought Conditions mid-June 2012: 69% in West, 57% in Southeast

13 Comments

The record warmth of the past six months in the US was more than just a set of numbers or a temporarily interesting headline.  Along with the heat, precipitation for most of the southern half of the country has been below average in the past few months.  The result?  At least some level of drought conditions exists today across the Western US, with a significant portion of the Southwest (CO, NM, AZ, NV) experiencing Severe drought:

As you can probably tell from Figure 1, the Pacific Northwest had below average temperatures and above average precipitation during the same time period, thus the relative lack of drought in OR, WA, ID & MT.

Interestingly, the areas experiencing the most severe level of drought are also those with the largest wildfires: the High Park fire in my state and the Little Bear and the Whitewater-Baldy Complex (at 289,478-acres as of yesterday!) fires in New Mexico.  An additional link to climate change here: the High Park fire is burning in an area that the the pine beetle epidemic has devastated.  The epidemic has left over 3.3 million acres of forest in just Colorado with dead trees.  The beetles’ population have exploded in the past 20 years as winter nighttime lows warmed enough to allow more larvae to survive the coldest months of the year.  This epidemic will transform the inter-mountain West.  Combined with the extensive drought, millions more acres of trees will succumb to the epidemic.

Meanwhile, the Southeast finally got some relief in the past week and a half due to very heavy rainfall.  The result is clear in the table below: the percent area experiencing drought has dropped significantly, from over 75% three months ago to 57% this week.  Unfortunately, the areas with the worst drought conditions didn’t get their long-term drought busted, especially Georgia.  This area typically receives some relief from drought during the Atlantic tropical storm season.  The Atlantic has been quiet for the past few weeks, however.  The Southeast will have to wait a bit longer for additional relief.

Drought has been present across GA for the better part of a year now.  The area affected by drought has expanded to neighboring states during the end of the winter and beginning of spring, then shifted in the last month due to weather systems moving through.

There’s no crisis to speak of yet, but inhabitants as well as policymakers should monitor conditions as the year progresses.  These conditions are not a result of climate change in any direct way.  They are simply a result of a chain of events, some of which (e.g. Arctic ice loss in recent years) are more directly related to climate change than others.

  2. This drought crisis as related to the economy is much more serious than any realizes. That’s because we had “drought prices” for the grains in 08, 2011, and now in 2012. This can be verified by the 25 year corn and soybean charts.

    My objective is to make people aware of the fact that the price of those commodities was manipulated and that we the people; the multitudes have once again been exploited by the 1%, and nobody but us will pay the price. While that sounds like some kind of wild, “party propaganda” talk, it’s “hard copy” fact.

    All of this will be moot after the election. The multitudes have been exploited and no one is prosecuted. I believe my objectives overlap with Weatherdem. However, in all honesty I must tell you before you get any ways involved with my objectives, they are white hot; “If you can’t stand the heat, don’t come into the kitchen”

    • Indeed, commodity prices are also manipulated by monied interests who don’t seem to have anything better to do with their vast wealth.
      Natural phenomena like drought certainly don’t help – and the people that end up worst affected are those who have the fewest material resources.
      Thanks for reading & the comment.

  3. Superb, what a weblog it is! This weblog gives valuable information to
    us, keep it up.

  4. First of all I want to say awesome blog! I had a quick question that I’d like to ask if you don’t mind.
    I was curious to know how you center yourself and clear your mind before writing.
    I have had difficulty clearing my mind in getting my thoughts out
    there. I do enjoy writing however it just seems like the first 10 to 15 minutes are usually lost simply
    just trying to figure out how to begin. Any ideas or tips?

    Appreciate it!

    • That’s a good question. There are some posts which I have more difficulty writing than others, but I’ve practiced writing posts like this for years, so overall it’s easier.
      I would recommend starting by figuring out what your goal for writing a particular piece is, then try to identify up to three bullet points that support that goal. Flesh out each bullet point little by little and before you know it, you’ll have something you think is worth publishing.
      My thoughts can wander when I first sit down to write. When you’re writing, if you have what seems like a stray thought flit by, write it down – either in your post or on a piece of paper. Usually, those stray thoughts are relevant to what you’re trying to write. I think of it as my subconscious answering my call for creative assistance.
      Best of luck!

  5. I simply wished to thank you so much once more.
    I’m not certain the
