Drought Conditions Continue In Colorado

Even though most areas along the Front Range of Colorado have seen over 1″ of precipitation in the last couple of weeks, drought conditions continue to affect the region.

According to the U.S. Drought Monitor (NOAA’s NCDC), those conditions start along the east side of the Continental Divide and grow steadily worse as you look east and south.  22 counties are completely covered by `Severe` drought conditions.  Additional counties have at least some area in the Severe category.  Unfortunately, Baca County in southeastern Colorado has slid into the `Extreme` drought category.  One of my close friends has a place down there – I know the communities in Baca are growing increasingly worried about these conditions.

Some good news might be on the horizon.  The moderate La Nina that has been present is finally starting to weaken: neutral El Nino conditions (+/- 0.5C temperature anomalies) are expected to prevail across the tropical Pacific later this year.

Combined with the North Atlantic Oscillation retreating from its extreme negative phase earlier this winter to more neutral conditions, the polar and subtropical jet streams should be returning to more “normal” placements and strengths.  This could hopefully mean that normal storm tracks will again appear over Colorado this summer.  If the monsoon shows up this year, that would be great too.

I’m pleased as punch that many mountain sites have near-record snowpack this year.  The plains sure could use some moisture moving into 2011.  Nobody wants to see the conditions in Texas affect other places.

Canadian Glaciers, Ice Caps Melting Too

Glaciers and ice caps in the Canadian Arctic Archipelego have started melting.  This will contribute to sea-level rise for the remainder of the 21st century.  That’s a problem because the area contains one-third of the global volume of land ice outside the ice sheets.

Researchers found that the islands lost about 61 gigatonnes of ice per year from 2004 to 2009, enough to raise global sea levels about a millimeter in that time.

That rate of melt will only increase in the years ahead.  More mass into the world’s oceans and more heat accumulated from global warming means the rate that sea level rise is increasing will also increase.  And because of the out-sized influence of the dirty energy industry and its apologists, we remain unprepared for that situation.  Preparing for it will only become more expensive with time.


State of the Poles – Apr. 2011: Arctic Sea Ice Steady; Antarctic Below Average

The state of global polar sea ice area in the middle of April 2011 remains poor: well below climatological conditions (1979-2009) continue to persist.  Sea ice in the Arctic continues to track significantly below average, with the 2nd lowest readings for the month in the modern era.  Antarctic sea ice has rebounded very slowly from its annual minimum extent, hovering near record low extent values during March and only recently improving in comparison to historical lows in early April.  Global sea ice area has therefore remained near historical lows for an extended period of time this year.  While global sea ice area has rebounded from its yearly minimum, the difference between this year and climatological conditions has been stuck below negative 1 million sq. km. for the first 3.5 months this year.   Those conditions mimic the trend seen in early 2006 and 2007.  2006 saw the global area increase to normal conditions later in the year.  2007, in contrast, did not.  That, of course, was the year that Arctic sea ice extent plummeted to its lowest value on record.  Weather conditions in the Arctic the rest of this year will help determine whether 2011 challenges 2007 for that dubious position.

Arctic Ice

According to the National Snow and Ice Data Center, Arctic sea ice extent in March was the 2nd lowest on record.  Averaged over March 2010, Arctic sea ice extent was only 14.56 million sq. km.  Arctic ice in March and into early April didn’t change very much in its extent.  This is definitely typical for March, but less so for April.  In fact, overall conditions have held steady since mid-February.  While those conditions were extremely low compared to climatological conditions in February, they were less anomalous by the middle of April.  Climatologically, the extent starts to really decrease by the beginning of April, so the extent anomaly has sharply decreased in the past month from 1.1 million sq. km. below normal to “only” 574,000 sq. km. below normal now.  Hopefully that translates to the lack of record low extents later this year.

The change in March ice extent has been measured at -2.7% per decade by the NSIDC.  What that means is as of the end of March 2011, the Arctic has only 14.56 million sq. km. of sea ice extent, while as of the end of January1978, the Arctic had 16.49 million sq. km. of sea ice.  That difference is real and it is significant.

Arctic Pictures and Graphs

I’m going to do something a little different this month and compare April’s satellite imagery of the Arctic to February’s to demonstrate the general lack of difference between the two.

Compare this with February 7th’s satellite representation, centered on the North Pole:

A couple of areas have some lower concentration of sea ice, but the general picture looks the same as it did over two months ago.  One important factor in April’s conditions is the Arctic Oscillation’s return to more positive values since the beginning of the year.  This has allowed colder air to remain in place over the Arctic region.

As a whole, here is what the Arctic ice extent looks like in time-series form through April 19th:

The NSIDC has included the 2007 time-series line as a useful comparative measure for this year’s extent.  After trailing below 2007 conditions for the first 2 months this year, the unchanging extent since early March has meant 2011’s extent is now above 2007’s.  At the end of the 2011 series, you can see that this year’s melt season might finally be in effect.

Antarctic Pictures and Graphs

Here is a satellite representation of Antarctic sea ice conditions from April 19th:

For comparison purposes, here is the similar picture from March 2nd:

Sea ice conditions have obviously increased in the last month, as they should have.  To date, I haven’t seen anything regarding the health of the ice shelves ringing the continent.  The longer there is no news, the better, since those shelves keep the land-based ice on land and not allowing them to escape to the sea.

Here is the time series graph of Antarctic sea ice extent with the +/- 2 standard deviations in light gray and the climatological mean in dark gray through April 19th:

Antarctic sea ice extent has remained on the low side of the climatological envelope of conditions.  So far, April has seen more extensive freezing than did March.  As you can see, conditions this year have been worse than conditions in 2010.  Unlike the Arctic, however, a long-term trend has not been as dramatic in the Antarctic.


Here are my State of the Poles posts from March and February.

You can find the NSIDC’s April report here. The page is dynamic, so if you’re reading this after April 2011, that month’s report will show up first. If that’s the case, you can look for any report in their archive on the top pull-down tab on the right-hand side of the page.

New Reports: Climate Inaction More Expensive Than Action

For those of you who have followed this topic to a reasonable degree, you probably already knew what the lede had to say.  For those of you who don’t pay quite as much attention to this topic, this post is especially important.  The dirty energy worshippers have screamed about the costs of doing what’s required to keep our climate livable for some time now.  Left unsaid during that whole period (thanks for that, corporate media) is the alternative: what would doing nothing and hoping our climate remains livable cost?

Some basic studies have been performed to ask that second question in recent years.  They mainly deal with large-scale (national) economies and make a ton of generalizations and assumptions.  Part of the problem is too little fundamental research has been performed examining what kinds of benefits we enjoy in a livable climate and what they should be worth to us.

On top of that, I have spent a lot of time and effort detailing a lot of the disadvantages of the assumptions made and processes left out of climate research to date.  Keep that in mind: everything discussed here remains based off of data that contains too many unrealistic assumptions and therefore likely underestimates the problem at hand.  Unfortunately, that’s all we have to work with right now.  Some of those gaps will continue to be filled in the future, enabling more detailed and accurate cost analyses to be performed.

The American Security Project has released analyses for all 50 U.S. states’ costs as a result of doing nothing to stop our climate forcing.  The report for my state, Colorado (pdf), has some interesting results.

I will begin with an enormously important note underlying their entire analysis: the calculations performed do not include snowfall and icepack melts, which the study itself notes “Coloradans depend on for much of the water supply and recreation”.  That seems to me to be a critically important piece of information when judging what costs to society global warming will bring about: will we have water to drink or not?  It goes to basic survivability.  Nevertheless, the rest of the results have to be viewed through the lack of snowfall and icepack melt lens.

Temperatures are expected to rise 4-10ºF by the end of the century.

Water shortages could become a regular occurrence throughout the state.

Corn and wheat yields are projected to decrease by 8-33% as a result of water shortages.

Warmer temperatures and drier summers will lead to more fires throughout the state.

Colorado’s $1.9 billion ski industry—which employs 31,000 people – may become unprofitable as decreasing snowpacks will shorten the winter sports season by an estimated 30 days.

When global warming scenarios that are based on our current emissions path are considered, some notable differences appear.

Temperatures could rise by 13-18ºF by 2060.  That’s only 50 years from now, not 90.  So much hotter, much sooner.

Droughts could occur by 2060 that would make the Dust Bowl look moist by comparison.  We’re in line to witness weather extremes that nobody in our species’ existence has faced.

With those kinds of higher temperatures and extreme droughts, agriculture and ranching would be impossible to conduct in most areas where they take place today (an increase of only 3-4ºF would likely be enough to force ranchers to move herds out of the state; where they would go instead is an interesting question left unconsidered), wildfires could burn at least twice as much area per fire year (May-October) as they do today.  Of course, this year’s wildfire season started months early, thanks to the medium-term drought we’ve been in.  If  more snow falls as rain in the future, the ski industry will definitely become unprofitable by mid-century.

Some good news was also identified in the report:

Colorado has the potential to generate more than 35% of its electricity needs from geothermal energy. Its wind energy potential is even greater; the state could generate 1,100% of its current electricity use by employing this renewable source.

The state could also generate over 1000% of its current electricity use by leveraging solar energy potential.

Will it cost money to switch from dirty to clean energy sources?  Absolutely – nobody has ever seriously advocated otherwise.

But would the costs of not making that switch be even higher?  Yes.  According to the International Energy Agency (IEA), the world will have to spend an extra $500 billion to cut carbon emissions for each year it delays implementing serious action on global warming. This would be on top of the $10.5 trillion investment needed from 2010 to 2030 to boost renewable energy development and improve energy efficiency.  And that’s just added costs to switching our energy infrastructure.  That analysis didn’t look at rising sea levels, rising temperatures, more severe droughts, acidified oceans, or geopolitical unrest as millions more climate refugees start moving around, etc.

Suddenly, the costs of switching to renewable energies and living more efficiently looks pretty cheap.

Will Democrats Push Back On Republican Teabaggers’ Attempt To Gut Medicare?


And I really do think it’s that simple.  Obama has already ceded the majority of the ground that could honestly be considered liberal.  That’s the way he wants it; that’s the way his handlers want it; it’s become the way his supporters want it.  He’s made plenty of pretty-sounding speeches about the topic, saying over and over he won’t let Medicare be turned into a voucher system.  Which tells me that is where things will end up when all is said and done.  Contractual obligations don’t matter to this man or his staff.  Staying in power does.

Mark my words: the big 3 contractual obligations run by the federal government will look very different after Obama and other “Democrats” are done with them.  Those changes might not take place immediately, but they’ll take place.  Just like his health care system reform insurance giveaway – the biggest changes still won’t take place for years, but they’re coming.  And when they get here, it’s not as if the system will be better than was before the reform.  And the Obama drones will swear up and down that the destruction of Medicare will be as good for all of us as the health insurance giveaway was.

Want to prove me wrong, Obama?  Fine, prove me wrong.  Don’t let Republican Teabaggers start the process to destroy programs that have worked quite well for generations.  Actions speak louder than words.  Stand up to extremists for once instead of trying to figure out a way to help them stab the rest of us in the back.

March 2011 CO2 Concentration: 392.40ppm

An average of 392.40ppm CO2 concentration was measured at NOAA’s Mauna Loa, Hawai’i’s  Observatory during March 2011.

That value is the 3rd highest in recorded history, behind April and May 2010.  392.40 is the highest March value ever recorded. It is 1.39ppm higher than March 2010.  It is 0.63ppm higher than February 2011.

A rough extrapolation of last month’s concentration projects out to 394-395ppm in May, the month during which the yearly maximum concentration is recorded.

This will likely be the last year that CO2 concentrations will fall below 390ppm during any calendar month.  The aggressive march toward 400ppm continues.  Keep in mind that scientists have recommended that 350ppm is the current target for which humanity should aim in order to keep climate extremes from overwhelming our civilization.

Eastern Colorado In Grips Of Severe Drought

If you haven’t heard or read by now, I’m sorry to be the first to let you know: as of early 2011, eastern Colorado is experiencing a severe drought.  The mountains and the western slope are doing just fine, thanks to a strong La Nina that has brought above-average precipitation to western Colorado all winter.  The eastern plains, however, have received scant precipitation dating back to just after July 4th, 2010.  the precipitation that has fallen in the Denver metro area, for example, since that time has been largely confined to singular events followed by weeks of no precipitation.  Coyote Gulch has a piece on what this means for the Arkansas Valley farmers.

For the record, as dry as it has been over eastern Colorado for the past 9+ months, Oklahoma and Texas are doing relatively worse.  Extreme drought conditions exist over a large part of southern Oklahoma and most of Texas.  A portion of Texas near Houston is experiencing Exceptional drought conditions.  The same La Nina that has brought near-record snowpack to the Sierra Nevadas and saturated the Pacific Northwest has left the southern U.S. high and dry.  That’s not expected to change in the next 3 months as the La Nina slowly weakens and the tropical Pacific returns to neutral conditions.

In the long term, these kinds of events are only going to become more likely and more severe, regardless of the specific strength of a particular La Nina or other short-term climate oscillation.  I’m not saying this drought will continue for years to come, but as a result of our climate forcing, the drought dice are being loaded more and more.  We will learn what it’s like to hit a 13 or 14 on 2 six-sided die that we’re painting with extra numbers this century.  Mankind has never had to deal with the kind of climate extremes that will occur.

The effects of this drought have yet to really be felt. Once they do, we should all ask ourselves how prepared we are to face much more severe droughts in the future.

Budget “Compromise” Cheered by Obama, Sen. Reid

Well, congratulations are in order to the richest and most out of touch people in the country: politicians in D.C.  After weeks and months of so-called tough negotiations, $38 billion in cuts to services to the poorest Americans was achieved.  This only came a few short months after un-paid for tax cuts were extended to the richest Americans.  That was sold as a “tough compromise” too.

I hope everybody notices who’s doing the compromising and who’s losing in all of this.  Spineless Corporate-Crats are the ones compromising the very same Americans they promise every other year to look out for.  We all know the Corporate-Cons have a deep-seated, irrational hatred for working Americans.  The poorer they are, the more they’re hated by the old white men’s club.

The problem with the federal budget is more of a revenue problem than a spending problem.  The problem with the federal budget is 2 occupations and 1 war, followed closely by welfare for the rich.  If those spending problems were halted, the budget problem would largely disappear.  As usual, the Corporate-Crats don’t want to talk about those problems any more than the Corporate-Cons do.  And because elections have become popularity extravaganzas, the pro-Corporate wing of our government is under no pressure to talk about them.  And so the situation that came to a head last night results: poor and working class Americans get their critically needed services cut.  A harsh analysis concludes that those Americans might deserve what they’ve wrought.  If they paid more attention to the type of candidates they voted for, they might not be in this situation.  Unfortunately, programs will likely be cut much further or eliminated before enough Americans figure out what’s really going on in their capital.  By then, it might be too late.

I want to hear more from the “pragmatic” crowd that gets so loud just prior to elections, when they tell the rest of us we have to suck it up and vote for the lesser of two evils, because that’s just the way it is.  That cowardly approach to politics is manifesting into more of our realities now.  When you vote for the lesser of two evils, you’re still voting for evil.  You might delay when evil takes over, but you’re ensuring that sooner or later it will do just that.  I want those “pragmatists” to tell the people who will go without the services they need that it’s for their own good; that our political system had to produce this result.  Of course, responsibility for one’s words and actions is severely lacking in today’s political world.  This situation will be no different.

The Corporate-Cons on TV are crowing about this, and well they should.  They won this first fight and they won it big time.  The Capitulator-In-Chief and the Spineless Boxer from Nevada will make sure that the next round of fights will go for the Corporatists, mark my word.  That they had to “fight” so hard to save health clinic and EPA funding is a testament to how crappy their negotiating skills really are.  There is no way the Corporate-Cons should have been able to look reasonable demanding their extremist social agenda be forced on the remainder of America.  But it very nearly was.  How much further to the right will the social extremists move in order to achieve what they want?  As far as they can possibly imagine, because it’s not like Obama and Reid have shown any kind of acumen to be able to stand up for principles.  Those health clinics will likely lose their funding before this Congress ends.  Medicare and Medicaid will be eliminated soon thereafter.  And those things are likely to occur with a “Democratic” President and Senate.  How pragmatic does that sound?

Additional Geoengineering Is NOT The Solution To Global Warming

Too much attention is being paid to identifying a geoengineering “solution” to the developing global warming crisis we face.  Human forcing of the Earth’s climate system has become the dominant mechanism affecting that system.  Anthropogenic forces have overtaken the solar cycle and short- and medium-term natural oscillations in generating climate effects.  This simple fact is largely left out of geoengineering discussions: we are already conducting the largest geoengineering project in the history of our species.  That project is having measurable, real-world effects.  The best way to slow down and stop those effects from taking place is to stop the geoengineering project.  Quite simply, we must stop polluting the climate system with man-made greenhouse gases.

Charles Hanley of the AP has an article posted at the HuffingtonPost regarding a recent meeting of scientists and scholars discussing additional geoengineering proposals, including their potential benefits and pitfalls.  He provides an accurate, unbiased assessment of the problem we face (emphasis mine):

The question’s urgency has grown as nations have failed, in years of talks, to agree on a binding long-term deal to rein in their carbon dioxide and other greenhouse-gas emissions blamed for global warming. The Intergovernmental Panel on Climate Change (IPCC), the U.N.-sponsored science network, foresees temperatures rising as much as 6.4 degrees Celsius (11.5 degrees Fahrenheit) by 2100, swelling the seas and disrupting the climate patterns that nurtured human civilization.

Unfortunately, that assessment doesn’t acknowledge the unrealistic assumptions that were made as part of the latest IPCC report, including a lack of the most meaningful positive process feedbacks (including ice cap melting and high-latitude methane outgassing) as well as generally ignoring the fact that some of their projections were already occurring decades early.

One of the geoengineering projects discussed in the article is reflecting enough sunlight to eventually reduce the solar input to the climate system.  That proposal should be considered weak for several reasons.  First, it ignores CO2 emissions and concentrations, which will be increasingly important to projecting the state of future climate moving forward.  Second, it ignores the carbon uptake by the oceans, which has already made conditions more acidic to ocean lifeforms.  Additional CO2 being absorbed by the oceans will increase the volume of ocean water affected as well as the magnitude of the problem.  If the bottom of the oceanic food-chain collapses, the top won’t be far behind.  All the sunlight reflected back into space won’t change that.  Third, how big of a system of reflectors would have to be manufactured and put into place (presumably orbit)?  To make a meaningful difference, the system would have to be huge.  Decreasing our greenhouse gas pollution, while a daunting task, will be much cheaper and easily attained than such a project.

Emissions are the primary cause of the problem we now face.  Anything that doesn’t directly address that problem is likely to only chase after the problem’s effects.
