Annals of Global Warming: Significant events for U.S. April 2014.


National Overview - April 2014, from NOAA's National Climatic Data Center

National Overview – April 2014, from NOAA’s National Climatic Data Center

NOAA publishes these data monthly.  We tend to ignore them, as background noise.

But click over to NOAA’s site, look at the charts and click to follow links.  Ponder the story being told.

This is the snapshot for April 2014.

Major climate events NOAA is closely monitoring:

  • Drought in the West, Central and Southern Plains, and Midwest. Long- and short-term dryness will increase wildfire risk and continue to have impacts on water resources and agriculture.
  • El Niño development likely this summer or autumn. According to NOAA’s Climate Prediction Center, there is a greater than 65 percent chance of El Niño conditions developing later this year, which could have significant impacts on temperature and precipitation patterns across the U.S. More information is available from the Climate Prediction Center.

Supplemental April 2014 Information


  • Climate Highlights — April
  • The average temperature for the contiguous U.S. during April was 51.7°F, which was 0.7°F above the 20th century average. This was the 46th warmest April in the 120-year period of record.
  • Much of the contiguous U.S. had April temperatures near the 20th century average. Above-average temperatures were scattered along the West Coast and in the Southwest, the Southern Plains, and across parts of the Ohio Valley and the Southeast. Below-average temperatures were observed across parts of the Upper Midwest and Northern Plains. No state had April temperatures among their 10 warmest or coolest.
  • Alaska had the 12th warmest April of its 96-year period of record, with a temperature 3.8°F above the 1971-2000 average. This was the warmest April for Alaska since 2007. Much of the warmth was situated in western Alaska, where Nome had its fourth warmest April since local records began in 1907. The April precipitation total in Alaska was 23.3 percent below the 1971-2000 average, the 23rd driest April on record. Anchorage had its fifth driest April with only nine percent of normal monthly precipitation.
  • The April contiguous U.S. precipitation total of 2.83 inches was 0.31 inch above the 20th century average and the 30th wettest April on record.
  • Above-average precipitation in the Upper Midwest resulted in Wisconsin having its third wettest April and Minnesota its eighth wettest. Heavy precipitation across the Southeast, particularly near the end of the month, caused Alabama to have its fifth wettest April, Georgia its seventh wettest, and Florida its ninth wettest.
  • On April 29th and 30th, torrential rain fell across the Southeast, Mid-Atlantic and Northeast causing significant flash flooding. The Gulf Coast of Alabama and the Florida panhandle bore the brunt of the heavy rains. At the Pensacola Regional Airport, in Florida, the two-day precipitation total was 20.47 inches, with 15.55 inches of the total falling on the 29th, breaking both one-day and two-day precipitation records; local records date back to 1879. On the 29th, Mobile, Alabama received 11.24 inches of rain, the third greatest calendar day rainfall total for the city since local records began in 1871. According to the 2014 National Climate Assessment released on May 6th, the amount of heavy precipitation falling in single events has increased by 27 percent across the Southeast since 1958. This event is consistent with projections of increases in the frequency and intensity of extreme precipitation events across the U.S. as the world warms.
  • Below-average precipitation was observed across parts of the West, the central Rockies, and the Central and Southern Plains. Oklahoma had its 12th driest April on record, with 50 percent of average precipitation. Parts of Texas were also particularly dry, where San Angelo observed just 30 percent of normal monthly precipitation.
  • According to the April 29thU.S. Drought Monitor report, 38.4 percent of the contiguous U.S. was in drought, nearly the same as the beginning of April, with both improvement and degradation of drought conditions on regional scales. Beneficial rain improved drought conditions across the Upper Midwest and Southeast during the month, while drought conditions worsened in parts of the West and across portions of the Central and Southern Plains.
  • Drought conditions improved in Hawaii during April due in part to heavy rainfall at the end of March and the beginning of April. Only 0.7 percent of the state was experiencing drought conditions on April 29th, down from 14.4 percent at the beginning of the month. This was the smallest drought footprint for Hawaii since April 2008, and the first time since June 2008 that no part of the state was experiencing severe drought. Most of the drought improvement occurred across the Big Island, with central Molokai still experiencing moderate drought conditions.
  • A severe weather outbreak on April 27-29 spawned at least 38 tornadoes from Nebraska to North Carolina, according to preliminary estimates from NOAA’s Storm Prediction Center. At least 32 fatalities were blamed on the tornadoes, with Arkansas and Mississippi being the hardest hit. An EF-4 tornado in Pulaski and White counties in Arkansas resulted in 15 fatalities, while an EF-4 in Winston County, Mississippi resulted in nine fatalities.
  • Based on NOAA’s Residential Energy Demand Temperature Index (REDTI), the contiguous U.S. temperature-related energy demand during April was 28 percent below average and the 37th lowest in the 1895-2014 period of record.
  • During April, there were about 75 percent more cold daily temperature records (1,419 cold maximum temperature records, 1,380 cold minimum temperature records; 2,799 total) than warm daily temperature records (544 warm maximum temperature records, 1,039 warm minimum temperature records; 1,583 total).
  • Climate Highlights — year-to-date (January – April)
  • For the first four months of 2014, the contiguous U.S. temperature was 38.7°F, 0.4°F below the 20th century average, and the 46th coldest January-April on record. This was the coldest four-month start to a year since 1993.
  • Below-average temperatures were widespread across the eastern U.S. where 13 states had January-April temperatures among their 10 coldest on record. The coldest departures from average occurred across the Midwest. No state had its coldest January-April on record.
  • Warm conditions were observed across a large portion of the West. Arizona and California were both record warm, with four-month temperatures 4.5°F and 5.2°F above their 20th century average, respectively. Nevada, Oregon and Utah each had one of their five warmest January-April periods on record.
  • The year-to-date precipitation total for the contiguous U.S. was 8.79 inches, 0.68 inch above the 20th century average and the 33rd driest January-April on record.
  • Below-average four-month precipitation totals were widespread across the Southwest and the Central and Southern Plains. Arizona, Kansas, New Mexico, Oklahoma, and Texas each had January-April precipitation totals that ranked among their 10 driest on record. Oklahoma had its second driest January-April on record, with less than half of average precipitation; 1936 was the driest. The dry conditions across Oklahoma decimated much of the winter wheat crop in the state, with estimates of the lowest harvested yield since 1957. In west Texas, precipitation deficits that date back to 2010 have been unprecedented in the observational record, with nearly every major reservoir in the region at less than 40 percent of capacity.
  • The U.S. Climate Extremes Index (USCEI) for the year-to-date was the 14th highest on record for the period at 145 percent of average. Elements that contributed to the above-average USCEI included the spatial extent of cold maximum and minimum temperatures, warm maximum temperatures and the spatial extent of drought. The USCEI is an index that tracks extremes (falling in the upper or lower 10 percent of the record) in temperature, precipitation and drought across the contiguous U.S.
  • Based on REDTI, the contiguous U.S. temperature-related energy demand during January-April was 27 percent above average and the 29th highest in the 1895-2014 period of record.

    Would love to see you try to put serious academic papers to any of those points. As Will Rogers said,

    It isn’t what we don’t know that gives us trouble, it’s what we know that ain’t so.

    1. Not true. The facts are that in the 1930’s hold more record high temps recorded.

    Further, there is no “warming” in the South Hemisphere, in fact, it is only existing mostly in the US. There is no warming in the atmosphere, it is only by surface measurements in the US. And, the US surface record is massively massaged and manipulated so to give such a record.

    2. So what?

    From a historical perspective, an atmospheric CO2 concentration of 400 ppm is actually almost scraping the bottom of the barrel. Over the Earth’s history, atmospheric CO2 concentrations have ranged from 180 ppm to 7000 ppm

    On that scale we are in fact today barely above the Earth’s record lows.

    Indeed, it is dangerously low. Below 150ppm, there would be no plant life, and we are far closer to that disaster then any fantasy you make up about more Co2.

    3. Climate change is absolutely driven by changes in atmosphere water vapor. There is no such thing as a greenhouse gas.

    4. There are not more violent weather. There is vastly more reporting about weather. You confuse the two to be the same.
    In fact, there are far fewer hurricanes in recent times then average – and even this is not abnormal

    4a.It is not my error. There is NO science that demonstrates your claims. None. It is all rhetoric and myth-making mixed with boogymen and monsters.

    5. None of this has caused the climate to change. These are localized. By your measure, Elephants, who in their migration wipe out vast tracks of vegetation cause climate change.

    No, sir. The climate is far more vast and complex then mere man.

    Climate change occurs constantly.

    But:

    1. Natural cycles point to our having entered a cooling period in the middle of the 20th century. Instead, we’re seeing record high temperatures.

    2. Not in human history, not in mammalian history, have we had carbon dioxide levels so high.

    3. Climate change hasn’t been driven by greenhouse gases for millions of years — and last time was one of the great extinctions (See the book, The Sixth Extinction about current, human-driven extinction).

    4. That Earth’s atmosphere, coupled with the aquasphere, is a negative feedback look accounts for more violent weather, a symptom of climate change. Climatologists have warned for 30 years that if we put too much energy in the atmosphere, there will be violent discharges to seek equilibria, and we will see stronger storms, summer storms and winter storms, and greater weather-related damage.

    You mistake a problem of human-caused climate change for an error in prognostication. Or do you really know what the scientists said and you decided to fib about it?

    5. Humans have caused climate disasters for thousands of years — the collapse of Babylon, the collapse of Mohenjo Daro, the several collapses of agriculture in China, the American Dust Bowl, the Aral Sea Disaster, etc. etc.

    This is just bigger than anything previous.

    Climate change has occurred since the beginning of the earth.

    Humans could not and cannot change the climate. You infer the earth’s system are massive positive feedback loops – where a small perturbation is magnified, when all of history shows the Earth’s systems exist as a negative feedback loops where massive perturbations, such as volcanoes, meteor strikes, plate tectonics, etc are mitigated.

    Your claim of “science” simply does not exist. It is pseudo-science and zealotry that you stand upon, not science.

    It is doubly folly to dismiss real science, and then claim falsely not to be doing so.

    Climate change is real. The Earth is warming. Human-caused pollution is a major contributor to the unnatural changes we see.

    It is merely a “pretend” to believe that “major” organizations support one thing or another is somehow indicative of science fact.

    History shows such folly.

    To believe that an organization, in control by a few, speak for the many, is a concept rooted in illusion.

    And to dismiss real science in favor of mere declaration is a sign of zealotry.

    In some minds, it’s the government to blame, yet EVERY major scientific organization agrees. And do the glaciers also agree to take part on this? I go hiking in the Rockies, and I’ll side with the Royal Society, NAS, and other venerable groups that have examined the evidence. Of course, if you distrust NOAA, you could look at other data sets not from them, such as BEST, HADCRUT, etc. WUWT heavily promoted BEST when it was established, but dkopped any mention when their data reflected reality, rather than predetermined biases.

    Ed, you do have sane readers.

    It is not unnatural at all, Ed!
    Nature is doing all the work.

    PS: We are not warming.

    Your claim is based on NOAA fudging the numbers:

    http://wattsupwiththat.com/2014/05/06/ive-been-waiting-for-this-statement-and-the-national-climate-assessment-has-helpfully-provided-it/

    NOAA is adding adjustments to make the present hotter and the past cooler….

    You are fooled by number manipulation – no surprise, since you do not understand the science.

    “…adjustments to the temperature record are increasing – dramatically. The present is getting warmer, the past is getting cooler, and it has nothing to do with real temperature data – only adjustments to temperature data. The climate reality our government is living in is little more than a self-serving construct.”

    Yet, I just ran into a blog writer who was outraged that anyone could claim that climate change is real since there were two days of rain in his hometown this week alone. ¡Ay, caramba! I dare you to find a better example of someone who completely misunderstands basic science and math concepts.
