California's Hot, Dry Winters Tied To Climate Change

mdsolar sends word that hot dry winters may be the norm in the future for California. "Climate change is one of the most prominent public health issues currently on the CDC's radar. The organization's Climate and Health Program attempts to help state and city health departments to prepare for the health impacts of climate change, which can come in the form of things like temperature extremes, air pollution, allergens, and changes in disease patterns; they can also be felt indirectly through issues like food security. Since 2012, California has been in the midst of a record-setting drought, with extremely warm and dry conditions characterizing the last three years in that state. A new paper published in the Proceedings of the National Academy of Sciences concludes that warming caused by humans is responsible for the conditions that have led to this California drought. This study, published by scientists affiliated with the Department of Environmental Earth System Science and the Woods Institute for Environment at Stanford University, used historical statewide data for observed temperature, precipitation, and drought in California. The investigators used the Palmer Hydrological Drought Index (PHDI) and the Palmer Drought Severity Index (PDSI), collected by the National Climatic Data Center, as measures of the severity of wet/dry anomalies. They also used global climate model simulations from the Coupled Model Intercomparison Project (CMIP) to compare historical predictions for anthropogenic and non-anthropogenic historical climates."

    Bullshit. The chart came from one Dr. Roy Spencer, who is not only a climatologist who has made a career out of claiming he's right and most scientists are wrong, but is also a noted creationist ("intelligent design, as a theory of origins, is no more religious, and no less scientific, than evolutionism" is my favorite quote from him on the topic).

    Here's a nice summation of how he fudged numbers in order to come up with that bogus chart: http://blog.hotwhopper.com/201...

    To your point of "I may be wrong", let me say, yes.... yes you are.

    I'm going to do something very foolish and imagine that you actually believe what you're saying, that you're not just being a troll, and that you actually think the data supports your conclusions. And now I'm going to explain why you're wrong, indulging in the fantasy that you'll listen with an open mind and, once you realize your mistake, freely acknowledge it. Prove me right. Or wrong. Your choice.

    Also, ignore the arctic ice that's been increasing for three years,

    Three years? Three years is random noise. The climate consists of steady, long term trends with lots of short term fluctuations superimposed on top of them. Take artic ice, for example. It shrinks every summer and grows every winter. There are lots of factors that affect the summer minimum: wind patterns, ocean currents, etc. A few years ago, lots of factors converged to give an exceptionally low minimum. It hasn't matched that since; but it's come close, and has remained far below anything seen until just a decade ago.

    Here's a graph showing sea ice for almost 40 years: http://nsidc.org/data/seaice_i.... Yes, it fluctuates up and down from year to year. But look at that and tell me it shows anything other than fluctuations around a steady decreasing trend that remains upbroken.

    Let's look at something even more convincing: world wide temperatures. http://data.giss.nasa.gov/gist.... Look at those graphs, and then tell me they show anything other than short term fluctuations on a long term warming trending that has been in place for the last century.

    Ignore Niagara falls that has frozen over two years in a row and ignore all the record cold around the country.

    Wrong! There has not been record cold "around the country". Believe me, the whole western half of the country has been getting record heat, as has most of the planet. Here's a map showing it: http://www.ncdc.noaa.gov/sotc/.... Those are the difference between Jan. 2015 temperatures and historical (1981-2010) average temperatures. The red areas are hotter than average. The blue areas are colder than average. Yes, there's a small blue patch over the eastern US. But overall there's a lot more red than blue.

    This is why scientists tend to prefer the term "climate change" to "global warming". Yes, the globe is warming up, but that doesn't mean everything is exactly the same, just uniformly warmer. Some times and places are a lot warmer. Others are only a little warmer. Others are actually cooler. Wind patterns are changing. Ocean currents are changing. Precipitation patterns are changing. Sea level is rising. Permafrost it melting. The climate is changing.

    And if you want to know precisely how global warming is causing unusually cold weather in the eastern US, take a look at http://en.wikipedia.org/wiki/P....

    Ignore the fact NAS falsified the CO2 hypothesis in 2010

    Sorry, but that is just BS. You linking to a story about how fungi help to hold onto carbon and keep it out of the atmosphere, and somehow translated that into "NAS falsified the CO2 hypothesis". No. I don't know what you think that article actually meant, but I can assure you that isn't what it meant. (OK, I see you also linked to that Register piece that totally misrepresented the conclusions of that study. The Register is a notorious denialist website. Believe me, the scientists who actually did the work would not agree with the conclusions they're trying to draw from it.)

    No one has "falsified the CO2 hypothesis". In fact, it was recently proven beyond a shadow of a doubt, by actually directly measuring the incoming and outgoing radiation, showing that the CO2 abso
