    India temperature rise concerns


    Rising temperatures caused by climate change are expected to "adversely impact" water supply, farm output and forests in India by 2030, a new study released by the government says.

    It has projected a temperature rise of between 1.7C and 2C in India over the next 20 years.

    The study says India faces increased precipitation and storms and a continuing sea level rise.

    Climate pledges fall short, says UN


    The promises countries have made to control carbon emissions will see temperatures rise by up to 4C during this century, a UN report concludes.

    China seeks carbon emissions peak at 'early date'


    BEIJING (AFP) ? China aims to achieve a peak in its greenhouse gas emissions "at an early date" but insists that developed countries bear the main burden for curbing carbon output, an official said Tuesday.

    "We will not allow our emissions to increase unchecked. China is taking decisive actions to slow down our emissions so that our emissions peak can come at an early date," said Xie Zhenhua, China's top climate change official.

    However, speaking at a briefing as the world prepares for next week's climate change summit in Mexico, Xie announced no new Chinese proposals for the talks.

    Climate science critic responds to allegations


    The author of a report critical of climate scientists defended himself against plagiarism charges Tuesday, and denied he was pressured by Republicans to tilt the report.

    Offered the chance to further respond to plagiarism allegations, reported Monday in USA TODAY, George Mason University statistician Edward Wegman said in an e-mail that "these attacks are unprecedented in my 42 years as an academic and scholar."

    Wegman was the lead author of a 2006 congressional climate science report that has become central in the debate over whether findings of global warming are warranted by scientific evidence.

    Three plagiarism experts contacted by the newspaper said excerpts in the Wegman report were likely plagiarized from various sources.

    The charges first surfaced on the Deep Climate website in 2009 and later in an analysis by retired computer scientist John Mashey of Portola Valley, Calif.

    GMU spokesman Dan Walsch said in an e-mail that the university is investigating the matter.

    "I will say that there is a lot of speculation and conspiracy theory in John Mashey's analysis which is simply not true," Wegman said.

    "We are not the bad guys. ? We have never intended that our Congressional testimony was intended to take intellectual credit" for other scholars' work.

    Wegman said he and his report co-authors felt "some pressure" from a House committee to complete the report "faster than we might like." But he denied that there was any attempt to tilt the influential climate report politically.

    He said the committee "wanted our opinion as to the correctness of the mathematics" used in two climate studies.

    "They wanted the truth as we saw it," Wegman said.

    Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia (2010)


    This new report from the National Research Council concludes that emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth's climate. Because carbon dioxide in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe. Therefore, emissions reductions choices made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia.

    Sorry deniers, Hadley Center and WMO say 2000s are easily the hottest decade in recorded history


    Last week, I pointed out that the climate story of the decade is that the 2000s are on track to be nearly 0.2°C warmer than the 1990s (see ?Very warm 2008 makes this the hottest decade in recorded history by far?).

    The World Meteorological Organization (WMO) reported today that because humans are altering the climate with greenhouse gas emissions:

    The ten warmest years on record have occurred since 1997. Global temperatures for 2000-2008 now stand almost 0.2 °C warmer than the average for the decade 1990-1999.

    Bad science: Global-warming deniers are a liability to the conservative cause


    In a new article published in the Proceedings of the Natural Academy of Sciences, a group of scholars from Stanford University, the University of Toronto and elsewhere provide a statistical breakdown of the opinions of the world?s most prominent climate experts. Their conclusion: The group that is skeptical of the evidence of man-made global warming ?comprises only 2% of the top 50 climate researchers as ranked by expertise (number of climate publications), 3% of researchers in the top 100, and 2.5% of the top 200, excluding researchers present in both groups ? This result closely agrees with expert surveys, indicating that [about] 97% of self-identified actively publishing climate scientists agree with the tenets of [man-made global warming].?

    Global Warming Deniers and Their Proven Strategy of Doubt


    For years, free-market fundamentalists opposed to government regulation have sought to create doubt in the public?s mind about the dangers of smoking, acid rain, and ozone depletion. Now they have turned those same tactics on the issue of global warming and on climate scientists, with significant success.

    The Warming of Antarctica:
A Citadel of Ice Begins to Melt


    The fringes of the coldest continent are starting to feel the heat, with the northern Antarctic Peninsula warming faster than virtually any place on Earth. These rapidly rising temperatures represent the first breach in the enormous frozen dome that holds 90 percent of the world?s ice.....


    ?If present trends in fossil fuel consumption continue...? he wrote in Nature, ?a critical level of warmth will have been passed in high southern latitudes 50 years from now, and deglaciation of West Antarctica will be imminent or in progress... One of the warning signs that a dangerous warming trend is under way in Antarctica will be the breakup of ice shelves on both coasts of the Antarctic Peninsula, starting with the northernmost and extending gradually southward.

    Wegman report round-up


    By email, he said, "there is a lot of speculation and conspiracy theory in John Mashey's analysis which is simply not true." He added, "we have never intended that our Congressional testimony was intended to take intellectual credit for any aspect of paleoclimate reconstruction science or for any original research aspect of social network analysis."


    "Unattributed near-verbatim copying is plagiarism, period, " Mashey says, by email. "In fact, much plagiarism (in the Wegman report) exists not to claim intellectual credit for discovering something, but to claim expertise as a base for making strong statements."

    Wegman under investigation by George Mason University


    George Mason University has acknowledged that statistics professor Edward Wegman is under investigation for plagiarism. As related in USA Today, the investigation followed a formal complaint by paleoclimatologist Raymond Bradley, co-author of the seminal (and controversial) 1998 and 1999 ?hockey stick? temperature reconstructions.

    Global and Regional Sea Surface Temperature Trends


    Global linear trends in the data-rich period between 1960 and 1990 calculated from the WOA94 data are found to be 0.14° ± 0.04°C decade−1 for the temperature class approach and 0.13° ± 0.04°C decade−1 for the 5° bin approach. The corresponding results for the COADS data are 0.10° ± 0.03°C and 0.09° ± 0.03°C decade−1. These trends are not statistically different at the 95% confidence level. Additionally, they agree closely with both SST and land?air temperature trends estimated from results reported by the Intergovernmental Panel on Climate Change. The similarity between the COADS trends and the trends calculated from the WOA94 dataset provides confirmation of previous SST trend studies, which are based almost exclusively on volunteer observing ship datasets like COADS.

    Does ocean cooling prove global warming has ended?


    Claims that the ocean has been cooling are correct. Claims that global warming has stopped are not. It is an illogical position: the climate is subject to a lot of natural variability, so the premise that changes should be ?monotonic? ? temperatures rising in straight lines ? ignores the fact that nature doesn?t work like that. This is why scientists normally discuss trends ? 30 years or more ? so that short term fluctuations can be seen as part of a greater pattern. (Other well-known cyclic phenomena like El Nino and La Nina play a part in these complex interactions).

    Looking at the trend in ocean heat, this is what we find:


    There are, however, disputes about the accuracy of Argo buoys and expendable measuring devices dropped into the sea, and the reporting of temperatures down to only 700 metres. How do scientists resolve these kind of disputes ? bearing in mind that such disputes are the very stuff of science, the essence of true scepticism? One way is to find more data sources ? different ways of measuring the phenomenon in dispute. By using results from seven different teams of scientists, all using different tools and methods, we are able to see a clear trend. And while there is variation between team results due to the differences in technique and measurement methods, one thing they all agree on: long term, temperatures are going up.

    First, I found science that says what I want. If you don't have science that says the opposite then by default you are wrong. If you find science that says the opposite and I don't like the sources you are wrong. If I think the source doesn't love trees or has any agenda other than trees then you are wrong.

    Second, give it up and change it now. We have to do this. Things are bad now. They might get better if you give up all your wifi. WE HAVE TO DO SOMETHING. Also what's wrong with doing something even if the result is nothing. The world might be a better place anyway. It can't hurt (by my reasoning which doesn't consider human needs or industry or well anything other than control of you) and so you should be forced to do it.

    Third, these trees are sick. They were sick before this to some degree but now more of them are sick. By default I blame wifi and thus we don't need any other explanation. My models might be completely wrong. They might need more refinement. My evidence might cause me to have to re-title, rethink and possibly alter entire conclusions and outcomes but it doesn't matter because it is science and your life must thus be under my control. It's different now and that is a good enough rationale for me to control your life.

    Please don't resist or be skeptical. That is just proof you are ignorant, evil, a denier and hate the planet.

    Send me your laptops and your wireless routers now you evil-doers. Do it now before I make a movie and millions while jetting around pointing my finger at you.

    First this isn't science. It was an untested hypothesis. If there was sufficient data to support it, and if it was published, it would be peered reviewed. However the deniers out there might use this to support their claim that science is faulty and we can't believe in AGW. More....

    Do Wi-Fi signals kill trees?


    It's an Internet rumor that is spreading, appropriately enough, like wildfire: Wi-Fi signals can make trees and other plants sick, causing cracks in their bark and killing off portions of their leaves.

    The outlandish claim, supposedly based on a Dutch study, cropped up late last week and has since been repeated in countless blog posts.

    In response, the Dutch government's Antenna Agency, which provides information on the health effects of electromagnetic fields, has issued a statement urging caution on the unpublished, unverified and otherwise very preliminary findings.

    Can the Arctic really become sea ice-free during summer?


    It has been suggested that the Arctic really can’t lose all its sea ice during summer because there isn’t enough energy to melt all of the ice in the short summer. There are a couple of reasons why this thinking is faulty.

    First, we know the Arctic can potentially lose all its sea ice during summer because it has done so in the past. Examination of several proxy records (e.g., sediment cores) of sea ice indicate ice-free or near ice-free summer conditions for at least some time during the period of 15,000 to 5,000 years ago (Polyak et al., 2010) when Arctic temperatures were not much warmer than today.

    Second, the primary evidence provided for the implausibility of ice-free summers is the plot of daily temperature for regions poleward of 80 degrees N from the Danish Meteorological Institute. It shows that temperatures rise only a couple degrees above freezing for a period of about 75 days throughout the entire record since 1958. So there is no warming trend of the surface air temperatures in the high Arctic. So how could one possibly melt ice near the pole with summer temperatures at most a couple degrees above freezing with no increasing trend?

    North of 80 degrees, the Arctic has been continuously covered by ice, even during summer, throughout the entire record (except for a small area briefly during summer 2007). As a result, any heat energy in the vicinity will be used to melt ice and will not raise temperatures. Only after the ice melts can the ocean absorb the energy allowing the ocean surface and the air above it to warm significantly. So the summer near-freezing temperatures don’t say anything much about the energy available to melt ice, only that ice is melting. (I’ll note that it is possible to have higher air temperatures locally, for example due to a weather system bringing in warm air from the south, but the average over the entire region will stay near freezing).

    However, there are still only ~75 days of melt, which isn’t much time. But one needs to think about the overall process of what happens in the Arctic, not simply the direct solar energy. As temperatures increase, summer extent decreases, which allows more absorption of solar energy. This melts more ice, decreasing the extent and thinning the ice. Heat absorbed in the ocean away from the ice edge will warm the ocean waters, which will delay freeze-up in the fall. This leads to less ice growth further thinning of the ice. With warmer temperatures, melt will begin earlier in the spring and freeze-up will start later in the fall (as has been observed, e.g., Markus et al. [2009], Serreze et al. [2009], Stroeve et al. [2006]). This is a positive feedback (the sea ice-albedo feedback). Under this feedback, the ice will eventually become thin enough to melt completely most everywhere in the Arctic during a single summer.

    There is little doubt in the sea ice community that during summer the Arctic can become ice-free and will become ice-free as temperatures continue to rise.

    Impacts of Climate Change on the European Marine and Coastal Environment - Ecosystems Approach


    ?..Recent research, including the examination of ice cores and growth rings of ancient trees, shows that the Northern Hemisphere has been warmer since 1980 than at any other time during the last 2000 years. The observed increase in temperature under climate change was generally higher in northern than in southern European seas....

    While on-going national and international actions to curtail and reduce greenhouse gas emissions are essential, the levels of greenhouse gases currently in the atmosphere, and their impact, are likely to persist for several decades. On-going and increased efforts to mitigate climate change through reduction in greenhouse gases are therefore crucial.

    In parallel, a better understanding of potential climate change impacts (scenarios) at both regional and local levels, the development of improved methods to quantify the uncertainty of climate change projections, the construction of usable climate change indicators, and an improvement of the interface between science and policy formulation in terms of risk assessment will be essential to formulate and inform better adaptive strategies to address the inevitable consequences of climate change......
