    The best argument against global warming

    Quote:

    Here is the best argument against global warming:

    . . . .

    Oh, right. There isn't one.



    There is no good argument against global warming. In all the brouhaha about tiny errors recently found in the massive IPCC report, the posturing by global climate deniers, including some elected officials, leaked emails, and media reports, here is one fact that seems to have been overlooked:

    Those who deny that humans are causing unprecedented climate change have never, ever produced an alternative scientific argument that comes close to explaining the evidence we see around the world that the climate is changing.

    World's lakes getting hotter, more than the air

    Quote:

    WASHINGTON ? A first-of-its-kind NASA study is finding nice cool lakes are heating up ? even faster than air.



    Two NASA scientists used satellite data to look at 104 large inland lakes around the world and found that on average they have warmed 2 degrees (1.1 degree Celsius) since 1985. That's about two-and-a-half times the increase in global temperatures in the same time period.



    Russia's Lake Ladoga and America's Lake Tahoe are warming significantly and the most, said study co-author Simon Hook, a scientist at the Jet Propulsion Lab in Pasadena, Calif. Tahoe has heated up by 3 degrees (1.7 degrees Celsius) since 1985, while Ladoga has been even hotter, going up by 4 degrees (2.2 degrees Celsius).



    The study was published Wednesday in the journal Geophysical Research Letters....

    Climate Science Rapid Response Team debunks Bjorn Lomborg?s Washington Post op-ed

    Quote:

    I?m sure the Danish statistician would appreciate Box Office Mojo quantitative detail, but you don?t need to know much statistics to realize that not bloody many people are actually watching this movie.



    In fact, the movie is just a clever loss leader for Lomborg?s bad ideas.* A film is a ticket to widespread media attention, far more than even a new book provides.* For instance, the movie means that credulous reviewers who don?t follow the energy and climate debate closely will write columns that millions will read (see ?Cool It and plausible deniability?), compared to the, uhh, hundreds that are flocking to the film.



    New Documentary on Bjørn Lomborg and Climate Change is Long on Opinion and Short on Facts, Science Group Says

    Quote:

    Lomborg cherry-picks data to present skewed view of how we should combat global warming



    A new documentary on climate change recently opened up in theaters. Titled ?Cool It,? it features a Danish political scientist, Bjørn Lomborg, who has stirred up controversy in the past by questioning the urgency of addressing the problem.



    The good news about ?Cool It? is that it doesn't dispute the reality of climate change. Lomborg accepts the overwhelming scientific evidence that burning coal and oil and destroying forests has overloaded the atmosphere with carbon dioxide, trapping heat that would otherwise escape into space, thus warming the planet and disrupting the climate.



    Instead, the film argues against ?fearing? climate change. It opens with animations and voice-overs from schoolchildren talking about climate change, including a child worrying that the Earth is getting ?very, very, very, very, very, very? hot.

    Climate talks focus on lesser goals

    Quote:

    One year after the near-collapse of climate talks in Copenhagen, participants will be hard-pressed to map a viable path forward. Global climate negotiations began in 1992 at the United Nations Earth Summit in Rio de Janeiro, Brazil, and led to the 1997 Kyoto Protocol, in which industrialized countries agreed to curb their emissions. But the protocol was intended as a first step, and countries have been struggling to agree on a follow-up treaty ever since. Jairam Ramesh, India's environment minister, says that Cancún is the "last chance" for such talks.



    Given China's continued opposition to a hard target for cuts in greenhouse-gas emissions, and the failure of the United States to pass climate legislation, there is virtually no hope of a binding global emissions treaty at the Cancún meeting, which will run from 29 November to 10 December.

    THE TRUTH REVEALED AS WORLD TEMPERATURES DROP FOR THE THIRD CONSECUTIVE YEAR

    Quote:

    The overall warming of the earth's northern half could result in cold winters. The shrinking of sea-ice in the eastern Arctic causes some regional heating of the lower levels of air ? which may lead to strong anomalies in atmospheric airstreams, triggering an overall cooling of the northern continents, a study recently published in the Journal of Geophysical Research shows. ?These anomalies could triple the probability of cold winter extremes in Europe and northern Asia,? says Vladimir Petoukhov, lead author of the study and climate scientist at the Potsdam Institute for Climate Impact Research. ?Recent severe winters like last year?s or the one of 2005-06 do not conflict with the global warming picture, but rather supplement it.?



    Study Could Mean Greater Anticipated Global Warming

    Quote:

    Current state-of-the-art global climate models predict substantial warming in response to increases in greenhouse gases such as carbon dioxide. The models, though, disagree widely in the magnitude of the warming we can expect. The disagreement among models is mainly due to the different representation of clouds. Some models predict that global mean cloud cover will increase in a warmer climate and the increased reflection of solar radiation will limit the predicted global warming. Other models predict reduced cloudiness and magnified warming. In a paper that has just appeared in the Journal of Climate, researchers from the University of Hawaii Manoa (UHM) have assessed the performance of current global models in simulating clouds and have presented a new approach to determining the expected cloud feedbacks in a warmer climate.

    Going After Regional Climate Patterns of Global Warming

    Quote:

    ?Compared to the mean projected rise of 1°C, such differences are fairly large and can have a pronounced impact on tropical and subtropical climate by altering atmospheric heating patterns and therefore rainfall,? explains Xie. ?Our results broadly indicate that regions of peak sea surface temperature will get wetter, and those relatively cool will get drier.?



    Threshold Sea Surface Temperature for Hurricanes and Tropical Thunderstorms Is Rising

    Quote:

    According to a new study by researchers at the International Pacific Research Center (IPRC) of the University of Hawaii at Manoa (UHM), this threshold sea surface temperature for convection is rising under global warming at the same rate as that of the tropical oceans. Their paper appears in the Advance Online Publications of Nature Geoscience.

    Carbon Dioxide's Effects on Plants Increase Global Warming, Study Finds

    Quote:

    ScienceDaily (May 4, 2010) ? Trees and other plants help keep the planet cool, but rising levels of carbon dioxide in the atmosphere are turning down this global air conditioner. According to a new study by researchers at the Carnegie Institution for Science, in some regions more than a quarter of the warming from increased carbon dioxide is due to its direct impact on vegetation.



    Map of globe shows percentage of predicted warming due to the direct effect of carbon dioxide on plants. Carbon dioxide warms the Earth because it is a greenhouse gas in the atmosphere, but it also causes plants to provide less evaporative cooling. A study by Long Cao and Ken Caldeira of the Carnegie Institution for Science finds that in some places (darkest orange) over 25 percent of the warming from increased atmospheric carbon dioxide is a result of decreased evaporative cooling by plants.

    Rising CO2 levels could reduce protein in crops

    Quote:

    Researchers found that plants lose the ability to take up so much nitrate ? the most common form of nitrogen in agricultural soils ? and convert it into organic compounds, such as proteins, when growing in CO2-enriched environments.



    The problem is that "most crop plants ... use nitrate as their main form of nitrogen," said Arnold Bloom, lead author of the study ? published in Science last week (14 May) ? and a researcher at the US-based University of California, Davis. Increasing the levels of CO2 leads to "nitrogen starved" crops that contain less protein for human consumption, he said.



    Effects of elevated CO2 on grain yield and quality of wheat: results from a 3-year free-air CO2 enrichment experiment

    Quote:

    Spring wheat (Triticum aestivum L. cv. TRISO) was grown for three consecutive seasons in a free-air carbon dioxide (CO2) enrichment (FACE) field experiment in order to examine the effects on crop yield and grain quality. CO2 enrichment promoted aboveground biomass (+11.8%) and grain yield (+10.4%). However, adverse effects were predominantly observed on wholegrain quality characteristics. Although the thousand-grain weight remained unchanged, size distribution was significantly shifted towards smaller grains, which may directly relate to lower market value. Total grain protein concentration decreased significantly by 7.4% under elevated CO2, and protein and amino acid composition were altered. Corresponding to the decline in grain protein concentration, CO2 enrichment resulted in an overall decrease in amino acid concentrations, with greater reductions in non-essential than essential amino acids. Minerals such as potassium, molybdenum and lead increased, while manganese, iron, cadmium and silicon decreased, suggesting that adjustments of agricultural practices may be required to retain current grain quality standards.

    Another extreme drought hits the Amazon, raising climate change concerns

    Quote:

    We know from simple on-the-ground knowledge that the 2010 drought was extreme, leading to record lows on some major rivers in the Amazon region and an upsurge in the number of forest fires. Preliminary analyses suggest that the 2010 drought was more widespread and severe than the 2005 event. The 2005 drought was identified as a 1-in-100 year type event.



    Scientists: ?There are multiple, consistent lines of evidence from ground-based studies published in the peer-reviewed literature that Amazon forests are, indeed, very susceptible to drought stress.?

    Quote:

    Up to 40% of the Amazonian forests could react drastically to even a slight reduction in precipitation; this means that the tropical vegetation, hydrology and climate system in South America could change very rapidly to another steady state, not necessarily producing gradual changes between the current and the future situation.



    ?AmazonGate?: how the denial lobby and a dishonest journalist created a fake scandal

    Quote:

    On January 25th, North published a post on his blog in which he dredged up one suspicious-looking claim made by the IPCC. On page 596, the second Working Group report had stated that ?40% of the Amazon forests could react drastically to even a slight change in precipitation?, potentially being replaced by ?ecosystems that have more resistance to multiple stresses caused by temperature increase, droughts and fires, such as tropical savannas?. Again, the reference given was to a WWF report ? in this case a Global Review of Forest Fires by a policy analyst, Dr PF Moore, and a journalist and campaigner, Andy Rowell. Apparently unable to find the information given by the IPCC in WWF?s report, North*wrote:

    ?The assertions attributed to them, that ?up to 40% of the Amazonian forests could react drastically to even a slight reduction in precipitation? is nowhere to be found in their report. ? Nor elsewhere can we find any other reference to 40 percent of the Amazon being affected by even slight reductions in precipitation.?

    Yet the fourteenth page of WWF?s report had stated exactly that. ?Up to 40% of the Brazilian forest is extremely sensitive to small reductions in the amount of rainfall?, the report noted.



    OK

    Passive smoking 'kills 600,000' worldwide

    Quote:

    The first global study into the effects of passive smoking has found it causes 600,000 deaths every year.

    One-third of those killed are children, often exposed to smoke at home, the World Health Organization (WHO) found.

    The study, in 192 countries, found that passive smoking is particularly dangerous for children, said to be at higher risk of sudden infant death syndrome, pneumonia and asthma.

    jg, thought we lost you.



    The deniers were half right: The Met Office Hadley Centre had flawed data ? but it led them to UNDERestimate the rate of recent global warming

    Quote:

    Claims that global warming has slowed down over the past decade were partly based on faulty data. Instead, the rate of global warming was underestimated because of a new way of measuring sea-surface temperatures, suggests a new study?.



    [Lead author John] Kennedy says the underestimation of the change in sea-surface temperature could account for up to 0.03*°C of the apparent slowdown in global temperatures. The correction could mean that 2010 will be the warmest year on record, surpassing 1998 and 2005.

    Royal Society special issue details ?hellish vision? of 7°F (4°C) world ? which we may face in the 2060s!

    Quote:

    ?Projections of global warming relative to pre-industrial for the A1FI emissions scenario? ? the one we?re currently on. ?Dark shading shows the mean ±1*s.d. [standard deviation] for the tunings to 19 AR4 GCMs [IPCC Fourth Assessment General Circulation Models]* and the light shading shows the change in the uncertainty range when ? climate?carbon-cycle feedbacks ? are included.?



    One of the greatest failings of the climate science community (and the media) is not spelling out as clearly as possible the risks we face on our current emissions path, as well as the plausible worst-case scenario, which includes massive ecosystem collapse. So much of what the public and policymakers think is coming is a combination of

    1. The low end of the expected range of warming and impacts based on aggressive policies to reduce emissions (and no serious carbon-cycle feedbacks)



    Quote:

    2. Analyses of a few selected impacts, but not an integrated examination of multiple impacts

    3. Disinformation pushed by the anti-science, pro-pollution crowd
