Other interesting things are happening on the planet we should possibly take note of. We can only play in the casino as the boat sinks for so long, especially after selling the life boats. American are particularly blind to this.
Asia and Southeast Asia have each recorded their hottest temperatures ever -- 129 degrees in Pakistan, and 117 in Burma. India is having the worst heatwave since the British started keeping records -- people are dying by the hundreds.

If it doesn't happen in the US, it doesn't count. And besides, one unusually cool day north of San Francisco is sufficient to counterbalance four months of record worldwide average high temperature. (Snark)

Glacial Earthquakes in Greenland and Antarctica
"The rate of glacial-earthquake occurrence increased between 2000 and 2005, with a stabilization of earthquake frequency at 2003–2004 levels in 2006–2008. Recent observations establish a strong temporal correlation between the distinct seismic signals of glacial earthquakes and large ice-loss events in which icebergs of cubic-kilometer scale collapse against the calving face, linking the seismogenic process to the force exerted by these icebergs on the glacier and the underlying solid earth"

Fungus, not comet or catastrophe, accounts for carbonaceous spherules in the Younger Dryas “impact layer”
"A claim attributes the onset of the Younger Dryas climate interval and a range of other effects ?12,900 years ago to a comet airburst and/or impact event. One key aspect of this claim centers on the origin of carbonaceous spherules that purportedly formed during intense, impact-ignited wildfires. Samples from Pleistocene-Holocene sedimentary sequences in the California Channel Islands and other sites show that carbon spherules and elongate forms are common in samples dating to before, during, and well after the 12,900-year time horizon, including from modern samples. Microscopic studies show that carbon spherules have morphologies and internal structures identical to fungal sclerotia (such as Sclerotium and Cenococcum). Experimental charring of fungal sclerotia shows that their reflectance increases with temperature. Reflectance measurements of modern and late Pleistocene spherules show that the latter indicate, at most, low-intensity burning. These data cast further doubt upon the evidence suggesting a catastrophic Younger Dryas impact event"

Climate Change, Water, and Risk
"Climate change will have a significant impact on the sustainability of water supplies in the coming decades. A new analysis, performed by consulting firm Tetra Tech for the Natural Resources Defense Council (NRDC), examined the effects of global warming on water supply and demand in the contiguous United States. The study found that more than 1,100 counties -- one-third of all counties in the lower 48 -- will face higher risks of water shortages by mid-century as the result of global warming. More than 400 of these counties will face extremely high risks of water shortages"

Phytoplankton in retreat
"Marine phytoplankton have a crucial role in Earth's biogeochemical cycles, and form the basis of marine ecosystems. Data from satellite remote sensing — available since 1979 — have provided evidence that phytoplankton biomass has fluctuated on the decadal scale, linked to climate forcing, but a few decades of data are insufficient to indicate long-term trends. Daniel Boyce and colleagues now put these results in a long-term context by estimating local, regional and global trends in phytoplankton biomass since 1899, based on a range of sources including measurements of ocean transparency with a device known as a Secchi disk, and shipboard analyses of various types. What emerges from the records is a century of decline of global phytoplankton biomass. The authors estimate that the decline of phytoplankton standing stock has been greatest at high latitudes, in equatorial regions, in oceanic areas and in more recent years. Trends in most areas are correlated significantly to increasing ocean warming, and leading climate indices"

State of the Climate in 2009
"The 2009 State of the Climate report released today draws on data for 10 key climate indicators that all point to the same finding: the scientific evidence that our world is warming is unmistakable. More than 300 scientists from 160 research groups in 48 countries contributed to the report, which confirms that the past decade was the warmest on record and that the Earth has been growing warmer over the last 50 years"

The Impact of Climate, Weather and Seasons on Economic Activity
Intensification of hot extremes in the United States
"Using a large suite of climate model experiments, we find that substantial intensification of hot extremes could occur within the next 3 decades, below the 2°C global warming target currently being considered by policy makers. We also find that the intensification of hot extremes is associated with a shift towards more anticyclonic atmospheric circulation during the warm season, along with warm-season drying over much of the U.S. The possibility that intensification of hot extremes could result from relatively small increases in greenhouse gas concentrations suggests that constraining global warming to 2°C may not be sufficient to avoid dangerous climate change"

New DNA evidence overturns population migration theory in Island Southeast Asia
"I think the study results are going to be a big surprise for many archaeologists and linguists, on whose studies conventional migration theories are based. These population expansions had nothing to do with agriculture, but were most likely to have been driven by climate change, in particular global warming and the resulting sea-level rises at the end of the Ice Age between 15,000 to 7,000 years ago"

How ocean color can steer Pacific tropical cyclones
"Because ocean color alters the absorption of sunlight, it can produce changes in sea surface temperatures with further impacts on atmospheric circulation. These changes can project onto fields previously recognized to alter the distribution of tropical cyclones. If the North Pacific subtropical gyre contained no absorbing and scattering materials, the result would be to reduce subtropical cyclone activity in the subtropical Northwest Pacific by 2/3, while concentrating cyclone tracks along the equator. Predicting tropical cyclone activity using coupled models may thus require consideration of the details of how heat moves into the upper thermocline as well as biogeochemical cycling"

"Using multiple lines of evidence, we demonstrate that volcanic ash deposition in August 2008 initiated one of the largest phytoplankton blooms observed in the subarctic North Pacific. Unusually widespread transport from a volcanic eruption in the Aleutian Islands, Alaska deposited ash over much of the subarctic NE Pacific, followed by large increases in satellite chlorophyll"

Geopiracy: The Case Against Geoengineering
- pdf 1.8MB (50 pages)
"Amidst growing public unease and increasing concentrations of carbon dioxide in the atmosphere, the Organisation for Economic Co-operation and Development (OECD) countries are feeling the pressure to “bite the bullet.” They either adopt socially-responsible policies to dramatically cut fossil fuel use and consumption, or they can hope for an alternative – a “silver bullet” in the form of an array of technofixes that will allow them to maintain the status quo and dodge the consequences. No surprise, the silver bullet option – most clearly embodied in the form of geoengineering – is gaining momentum. Also not surprising: the states in the global North, which are responsible for almost all historic greenhouse gas (GHG) emissions and have either denied climate change or prevaricated for decades, are the ones warming most quickly to the geoengineering option. And they will have de facto control over its deployment"
