First, let's start with the ground rules. Your participation is completely anonymous, and no attempt will be made to contact you for any reason as a result of your participation or anything you write in this survey.Here is where you can find the survey.
Second, this survey is not intended to be used as an opinion poll or a census, and will not be used as such. We are not trying to find out how many people 'believe' or 'disbelieve' in global warming. Our purpose is to try and find out if there are areas of agreement on possible policy initiatives going forward
Focusing on the past six decades, we observe no sustained upward trends in wind speed distributions (Figs. 1 and 3), the mean wind speed at landfall or the annual frequency of occurrence of landfalling segments (Fig. 8). (Note that this annual frequency is specific to landfalling segments and different from the annual frequency of landfalling events since some events have multiple landfalling segments, e.g. in 2005 Hurricane Katrina made landfall in both South Florida and Louisiana.) This being the case, the dramatic increases in total economic and insured losses from TCs, which have been manifest over the past six decades, indicates that the increasing losses must be attributed to the factors other than wind speed alone. This is in accord with recent studies (Pielke, 2005; Pielke et al., 2008; Crompton and McAneney, 2008), which demonstrate the importance of demographic changes in driving the increasing economic cost of hurricane losses.The paper concludes as follows:
The quality of observational data is central to the ongoing debate between a warming climate and consequences for TC frequency and intensities. Our analyses show clear, anomalous differences in the wind speed distributions between the early historical period and the very recent six decades. While these differences cannot unequivocally exclude a possible Global Climate Change cause, we suggest that data quality issues are more plausible.Find the paper here in PDF.
An enormous challenge lies ahead for recovering reliable wind estimates in the early historical record, especially for highly dynamic and short-lived extreme TCs. The counting of events by Saffir-Simpson Hurricane categories is determined by threshold wind speeds, and if the wind estimates are themselves unreliable, how can derivative statistics be trusted sufficiently for long-term trend analysis? It is timely to recognise that using the early historical record will inevitably involve some irreducible uncertainties and “fixing” these may not be possible and that more physically-based models are needed to help resolve the data impasse. Conclusions drawn from scientific and insurance applications using the inherently lower-quality components of the record should be treated with caution.
. . . attempts to “control” the climate system, and to prevent a “dangerous intervention” into the climate system by humans that focuses just on CO2 and a few other greenhouse gases will necessarily be significantly incomplete, unless all of the other first order climate forcings are considered.His views are now being robustly vindicated as a quiet revolution is occurring in climate science. Here is how PhysOrg reports on a study out today in Science by NASA's Drew Shindell and others:
Of note, Shindell et al. cautiously suggest that the entire framework of international climate policy may be based on an overly-simplistic view of the human effect on climate, by focusing on carbon dioxide equivalencies in radiative forcing (i.e.,g "global warming potential" or GWP), from their Science paper out today (emphasis added):According to Shindell, the new findings underscore the importance of devising multi-pronged strategies to address climate change rather than focusing exclusively on carbon dioxide. “Our calculations suggest that all the non-carbon dioxide greenhouse gases together have a net impact that rivals the warming caused by carbon dioxide."
In particular, the study reinforces the idea that proposals to reduce methane may be an easier place for policy makers to start climate change agreements. “Since we already know how to capture methane from animals, landfills, and sewage treatment plants at fairly low cost, targeting methane makes sense,” said Michael MacCracken, chief scientist for the Climate Institute in Washington, D.C.
This research also provides regulators insight into how certain pollution mitigation strategies might simultaneously affect climate and air quality. Reductions of carbon monoxide, for example, would have positive effects for both climate and the public’s health, while reducing nitrogen oxide could have a positive impact on health but a negative impact on the climate.
“The bottom line is that the chemistry of the atmosphere can get hideously complicated,” said Schmidt. “Sorting out what affects climate and what affects air quality isn’t simple, but we’re making progress.”
There are many limitations to the GWP concept (25). It includes only physical properties, and its definition is equivalent to an unrealistic economic scenario of no discounting through the selected time horizon followed by discounting to zero value thereafter. The 100-year time horizon conventionally chosen strongly reduces the influence of species that are short-lived relative to CO2. Additionally, GWPs assume that integrated global mean RF is a useful indicator of climate change. Although this is generally reasonable at the global scale, GWP does not take into account the rate of change, and it neglects that the surface temperature response to regionally distributed forcings depends on the location of the RF (26) and that precipitation and circulation responses may be even more sensitive to RF location (27). Along with their dependence on emission timing and location, this makes GWPs particularly ill-suited to very short-lived species such as NOx, SO2, or ammonia, although they are more reasonable for longer-lived CO. Inclusion of short-lived species in agreements alongside long-lived greenhouse gases is thus problematic (28, 29).The Shindell et al. paper comes fast on the heels of a paper published a few weeks ago in PNAS by Molina et al. which argued similarly that a broader perspective is needed on the human role in altering climate. They write (emphasis added):
Efforts to limit CO2 emissions alone may not be sufficient to avoid or reduce the risk of DAI on a decadal time scale, including the risk of abrupt climate change from committed warming (8, 9). . . there is growing demand among governments and commentators for fast-action mitigation to complement cuts in CO2 emissions, including cuts in non-CO2 climate forcing agents, which together are estimated to be as much as 40–50% of positive anthropogenic radiative forcing (17, 18). . .This recent research suggests that we must now be open to the possibility that there will not and cannot be a single policy approach to addressing the full spectrum of human influences on the climate system. The recognition of complexity may present an opportunity to move climate policy forward, by providing a justification for reconsidering the flawed (and some would say doomed) approach. My father has argued that (PDF),
The 2008 Major Economies Forum Declaration calls for ‘‘urgent action’’ to strengthen the Montreal Protocol for climate protection (22). The 2009 G8 Leaders Declaration calls for ‘‘rapid action’’ on BC [black carbon] and pledges to ensure HFC reductions (23). The 2009 North American Leaders Declaration commits to phasing down HFCs under the Montreal Protocol (24). The 2009 Arctic Council Tromsø Declaration urges ‘‘early actions’’ on short-lived climate forcers (25) including tropospheric ozone. A Nature editorial in July 2009, Time for early action, calls for ‘‘early action’’ on BC and methane, and on HFCs under the Montreal Protocol (26), and another in April 2009, Time to act, notes ‘‘short-term opportunities’’ to cut BC and methane (27). Wallack and Ramanathan call for action on BC and tropospheric ozone in their 2009 policy paper in Foreign Affairs to produce ‘‘rapid results’’ (28).
. . . humans have an even greater effect on climate that is suggested by the IPCC. The human influence on climate is significant and multi-faceted.As the community begins to realize these significant, multi-faceted and hideous complexities, it would not be a surprise to learn that a policy framework design 20 years ago is now somewhat out of step with current scientific understandings. The upshot is that as presently designed, international climate policy is both too complex and too simplistic. It is too simplistic because it is built upon a set of scientific perspectives on climate change that are increasingly seen as outdated and appropriate only for dealing with a narrow set of very important human influences -- long-lived greenhouse gases. It is too complex because in trying to deal with added complexity it has become unwieldy and clearly impractical from the standpoint of not just implementation but the politics of even reaching an agreement about implementation.
Exaggerated and inaccurate claims about the threat from global warming risk undermining efforts to cut greenhouse gas emissions and contain climate change, senior scientists have told The Times.
Environmental lobbyists, politicians, researchers and journalists who distort climate science to support an agenda erode public understanding and play into the hands of sceptics, according to experts including a former government chief scientist.
Excessive statements about the decline of Arctic sea ice, severe weather events and the probability of extreme warming in the next century detract from the credibility of robust findings about climate change, they said. Such claims can easily be rebutted by critics of global warming science to cast doubt on the whole field. They also confuse the public about what has been established as fact, and what is conjecture.
The experts all believe that global warming is a real phenomenon with serious consequences, and that action to curb emissions is urgently needed. They fear, however, that the contribution of natural climate variations towards events such as storms, melting ice and heatwaves is too often overlooked, and that possible scenarios about future warming are misleadingly presented as fact.
“I worry a lot that NGOs [non=governmental organisations] are very much in the habit of doing exactly that,” said Professor Sir David King, director of the Smith School for Enterprise and the Environment at the University of Oxford, and a former government chief scientific adviser.
“When people overstate happenings that aren’t necessarily climate change-related, or set up as almost certainties things that are difficult to establish scientifically, it distracts from the science we do understand. The danger is they can be accused of scaremongering. Also, we can all become described as kind of left-wing greens.”
Vicky Pope, head of climate change advice at the Met Office, said: “It isn’t helpful to anybody to exaggerate the situation. It’s scary enough as it is.”
She was particularly critical of claims made by scientists and environmental groups two years ago, when observations showed that Arctic sea ice had declined to the lowest extent on record, 39 per cent below the average between 1979 and 2001.
This led Mark Serreze, of the US National Snow and Ice Data Centre, to say that Arctic ice was “in a downward spiral and may have passed the point of no return”. Dr Pope said that while climate change was a factor, normal variations also played a part, and it was always likely that ice would recover a little in subsequent years, as had happened. It was the long-term downward trend that mattered, rather than the figures for any one year, she added. “The problem with saying that we’ve reached a tipping point is that when the extent starts to increase again — as it has — the sceptics will come along and say, ‘Well, it’s stopped’,” she said.
“This is why it’s important we’re as objective as we can be, and use all the available evidence to make clear what’s actually happening, because neither of those claims is right.” Myles Allen, head of the Climate Dynamics Group at the University of Oxford, said: “Some claims that were made about the ice anomaly were misleading. A lot of people said this is the beginning of the end of Arctic ice, and of course it recovered the following year and everybody looked a bit silly.”
Dr Allen said that predictions of how the world was likely to warm also needed to be framed carefully. While there was little doubt that the Earth would get hotter, there were still many uncertainties about the precise extent and regional impact.
“I think we need to be very careful about purporting to be able to supply very detailed and apparently accurate information about how the climate will be in 50 or 100 years’ time, when what we’re really giving is a possible future climate,” he added. “We’re not in a position to say how likely it is and what the chances are of it being different. There’s an understandable tendency to want to make climate change real for people and tell them what’s going to happen in their postcode, and that’s very dangerous because it gets beyond the level on which current models can operate.”
On climate change, the EU is keen to reach a united position ahead of December's United Nations Copenhagen summit, which aims to hammer out a new global climate treaty to replace the UN Kyoto Protocol.This is not the first time that eastern Europe has proven problematic in EU climate policy. But just wait until it comes time for the US to discuss how much money it is going to send overseas as a part of a climate deal. I can't imagine a situation in which this does not become a political lightning rod in the US -- regardless of the policy merits of doing so. (And to be perfectly clear about my views, I wrote in 1998 that the climate "winners" of the world have an obligation to help the climate "losers" - PDF - this post is about the politics of the issue.). Yvo de Boer, head of the UN FCCC helpfully explains that:
Mr Reinfeldt called on EU leaders to agree a "fixed sum" that would open the way for other rich donors like the US and Japan to make similar aid pledges to help developing nations cope with the effects of climate change.
But just hours before the talks, Hungarian Prime Minister Gordon Bajnai said sharing the aid costs equally between all 27 EU nations was out of the question. "The burden-sharing proposal is not acceptable in its current form," Mr Bajnai said.
The Polish finance minister, Jacek Rostowski, told the BBC that nine Eastern European nations were ready to block a deal unless they were allowed to contribute according to their means, not to how much they pollute.
"There are countries there like Bulgaria and Latvia, which are considerably poorer than Brazil, and which would be expected to help Brazil in its adjustments to climate change," he said.
“Money, in fact, is the oil that encourages commitment and drives action”Money also get the attention of voters, especially when you are reaching into their pockets to take it and then sending it to someone else. And in the United States, sending money overseas has never been politically popular, and I don't expect that it will be in the context either. I'll award a prize to the first person who can provide a quote from a U.S. elected official (POTUS, VP or anyone in Congress) advocating sending money overseas as part of a climate deal.
There is no doubt that energy is at the heart of many of the economic problems that Pakistan faces – the unreliability, the erratic cross-structure, the failure to capture the full load that is produced. It’s just a lot of problems. And one of the things that Ambassador Holbrooke’s team has done is to do an in-depth study of what are the most difficult issues, but what could be addressed in a very systematic way.
So as I said earlier, we made our announcement yesterday. But I appreciate the kind of chicken-and-egg issue that you were talking about – the more access, the more economic development, the greater the energy challenges. And I think that there is no prohibition that I know of internationally, and I asked Minister Qureshi whether there had been any prohibition nationally under developing your coal deposits. Now, obviously, that is not the best thing for the climate, but everybody knows that. But many of your neighbors are producing coal faster than they can even talk about it. It’s unfortunate, but it’s a fact that coal is going to remain a part of the energy load until we can transition to cleaner forms of energy.
So getting the resources to exploit your coal as opposed to being dependent upon imported energy is a choice for you to make, but it is certainly a choice that your neighbors have made. And that’s something that should attract foreign investment and should attract capital investment within your own country. And we don’t know how we’re going to proceed on the climate change issue. We’re working hard to come to some framework before Copenhagen, but coal will be, for the foreseeable future, part of the energy mix. And if you have these kinds of reserves, you should see the best and cleanest technology for their extraction and their use going forward.
Find the piece here. Comments welcomed.But evidence that climate predictions can provide precise and accurate guidance about how the long-term future may evolve is fundamentally lacking. Scientists and decision-makers alike should treat climate models not as truth machines to be relied upon for making adaptation decisions, but instead as one of a range of tools to explore future possibilities. A recent example2 from the Australian state of Victoria highlights the perils of relying on the predict-then-adapt mode of planning. In 2005, the Victoria government conducted a study to develop water-supply scenarios for its capital city Melbourne to 2020 under conditions of human-caused climate change. Before then, water planning in Victoria had been done with little consideration of the potential effects of climate change. The exercise resulted in a range of forecasts implying a 3-per-cent decline in storage under a 'mild' effects scenario and an 11-per-cent decline under a 'severe' scenario. The study concluded that the existing plan put into place in 2002 "provided [a] sufficient buffer ... across the full range of climate change and alternative demand forecasts considered in this case study" out to 2020.
If nature has a sense of humour, it is a vicious one. In 2006, water supply to Melbourne dropped to a record low level of 165 gigalitres (Gl), well below the 1913–2005 average of 588 Gl and the recently lower average of 453 Gl from 1996 to 2005 (Fig. 1). In the three years since the 2005 modelling study, the average water supply level was less than half the long-term average and well below the estimated outcome for the 'severe' scenario considered in the study.
Could the North Pole be ice free this melt season? Given that this region is currently covered with first-year ice, that seems quite possible.From the UK Met Office this week:
. . . the first ice-free summer [is] expected to occur between 2060 and 2080. It is unlikely that the Arctic will experience ice-free summers by 2020.Climate whiplash is a one good reason why efforts to motivate action should not be built on the backs of predictions.
"I firmly believe that if you had offshore drilling provisions, you would get more votes because people would see energy independence being achieved, and they would tolerate an emission control bill," Graham said. "You don't have to believe in climate change to vote for the bill I'm talking about. You just have to believe that controlling carbon is the way to get to energy independence."All who believe that offshore drilling is relevant to energy independence please raise your hands? The article explains that:
The specifics of Graham's plan would allow for "environmentally responsible" offshore drilling, revenues of which would be split between states as well as the federal government, the latter of which would use the revenue to reinvest in clean technology.
Graham was not specific as to how his plan would specifically regulate carbon emissions.
But pro athletes aren't actually more likely to commit crimes that the average citizen. It just seems that way because of all the attention their cases get.For the rest, click here.
"I don't think there's any empirical evidence showing that professional athletes are more likely to commit crimes than the typical person," says Michael McCann, a sports law expert at Vermont Law School.
Most players are "just regular citizens that follow the law and are as good or as bad as the rest of us," McCann says. "We're definitely skewed...because a handful of players get in trouble repeatedly."
Geoffrey Rapp, a law professor at University of Toledo, says he hasn't seen evidence to show there's more criminality among athletes, but the cases that arise make sense. "We're talking about people who their whole lives have been praised...for being violent."
"It's possible that athletes become a bit de-sensitized to the consequences of their actions," says Rapp. Plus, when people are wealthy, they "tend to think they can get away with murder."
But it's wrong to assume pros get off easy.
Lisa Kern Griffin, a professor at Duke Law, says that while sports stars may be better represented because of their wealth, "I don't think that athletes are treated differently in the courtroom." Plus, all the attention can mean they don't get off with small infractions that others may not be prosecuted for, says Griffin.
