Another 16 to 33 percent (10,000 - 20,000 vertebrates) are estimated to be globally threatened or endangered. 320 extinct seems like a small number. Looks like it could go either way from here.

Layzej Re:But what IS the point they're making? (242 comments)

They've been claiming for decades that if we don't do anything the sea will rise by 25m in two decades

You may want to check your sources. Likely you are being lied to, but not by scientists. More likely you've been reading denier blogs. Here is what the IPCC predicted 25 years ago: "For the 'Business-as-Usual' scenario at year 2030 global-mean sea level is 8-29cm higher than today with a best estimate of 18cm." - https://www.ipcc.ch/ipccreport...

Since 1990 we've already had about 8cm of sea level rise so we have already already within the projected range and we still have 15 years to go. The rate of rise is accelerating. Even at the current rate we will see about 13 cm rise by 2030. More if acceleration continues. Not far off from the predictions of 1990. - http://climate.nasa.gov/key_in...

You are off by a few orders of magnitude whereas the scientists have already been proven correct.

Earth In the Midst of Sixth Mass Extinction: the 'Anthropocene Defaunation'

Layzej Re:no problem (242 comments)

Nobody is citing climate change and all the animals they cite in TFS were extinct well before humanity is supposed to have had an impact on the planet's climate.

How about TFA?

Since 1500, more than 320 terrestrial vertebrates have become extinct. Populations of the remaining species show a 25 percent average decline in abundance. The situation is similarly dire for invertebrate animal life.

Across vertebrates, 16 to 33 percent of all species are estimated to be globally threatened or endangered. Large animals – described as megafauna and including elephants, rhinoceroses, polar bears and countless other species worldwide – face the highest rate of decline, a trend that matches previous extinction events.

The scientists also detailed a troubling trend in invertebrate defaunation. Human population has doubled in the past 35 years; in the same period, the number of invertebrate animals – such as beetles, butterflies, spiders and worms – has decreased by 45 percent.

As with larger animals, the loss is driven primarily by loss of habitat and global climate disruption, and could have trickle-up effects in our everyday lives.

Earth In the Midst of Sixth Mass Extinction: the 'Anthropocene Defaunation'

Layzej The point? Maybe RTFA? (242 comments)

Identifying the drivers of these extinctions is straightforward, but stemming the loss is a daunting challenge. Animal species continue to decline in, and disappear from, even large, long-protected reserves, due both to direct impacts, such as poaching, and indirect ecological feedbacks, such as habitat fragmentation. Though hunting and poaching might seem obvious candidates for targeted policy and management interventions, there are complex social issues underlying these activities that will require coordinated and cooperative actions by nations (see Brashares et al., p. 376).

While stemming this loss remains a challenging goal, attempts to reverse the extinction trend are increasing. Such “refaunation” efforts involve a variety of approaches, including breeding animals in captivity, with the hope of reintroducing them to the wild, and assisting recolonization of areas where species have become locally extinct (see Seddon et al., p. 406). Active reversal of animal extinctions is proving just as challenging as preventing extinctions in the first place, but a few success stories provide some hope. Many note and mourn the loss of animals but have not recognized that the impacts of this loss go beyond an aesthetic and emotional need to maintain animals as a part of nature. Current research reveals startling rates of animal declines and extinctions and confirms the importance of these species to ecosystems (see Stokstad, p. 396). Further, and more broadly, it suggests that if we are unable to end or reverse the rate of their loss, it will mean more for our own future than a broken heart or an empty forest.

The Last Three Months Were the Hottest Quarter On Record

Layzej Re: The Heartland Institute (552 comments)

Arctic sea ice is trending near record lows for this time of year, abnormally warm ocean water helped spawn the earliest hurricane ever recorded to make landfall in North Carolina, and a rash of heat waves have plagued cities from India to California to the Middle East.

Yikes, that all sounds alarming right? Except...

Except nothing. You can nitpick by look at this year or that, but look at the trend. Summer minimum extent has dropped by half and is accelerating: http://www.woodfortrees.org/pl...

the ice figures on that site you linked to are measured from 1979. You might want to ask yourself why.

It is because that's when they launched the satellite. But I'm guessing you believe there is a conspiracy to hide data from 1978 showing lower sea ice? I'd also wager a guess that you have doubts as to the authenticity of Obama's birth certificate.

How Did Those STAP Stem Cell Papers Get Accepted In the First Place?

Layzej Science works (109 comments)

There are examples where papers on global warming tried to game the system but were found out in short order. For an example see this article where Dr. Roy Spencer sneaked a botched paper past the peer-review system by submitting to an off-topic journal. Because the reviewers were not familiar with the topic they were not aware that the methodology described in the paper had already been refuted by previous literature. Within days the journal editor had resigned: http://science.slashdot.org/st...

“The problem is that comparable studies published by other authors have already been refuted in open discussions and to some extend also in the literature (Trenberth et al. 2010), a fact which was ignored by Spencer and Braswell in their paper and, unfortunately, not picked up by the reviewers.”

What does "spiral out of control" mean? The literature shows that there will be economic consequences to increased warming and that mitigation will be cheaper than adaptation. You will not find "spiral out of control" in the literature.

Global Warming Since 1997 Underestimated by Half

Layzej Layzej writes  |  about 8 months ago

Layzej (1976930) writes "A new paper shows that global temperature rise of the past 15 years has been greatly underestimated. The reason is that the weather station network covers only about 85% of the planet. Satellite data shows that the parts of the Earth that are not covered by the surface station network, especially the arctic, have warmed exceptionally fast over the last 15 years. Most temperature reconstructions simply omit any region not covered. A temperature reconstruction developed by NASA somewhat addresses the gaps by filling in missing data using temperatures from the nearest available observations. Now Kevin Cowtan (University of York) and Robert Way (University of Ottawa) have developed a new method to fill the data gaps using satellite data.

The researchers describe their methods and findings in this youtube video. "The most important part of our work was testing the skill of each of these approaches in reconstructing unobserved temperatures. To do this we took the observed data and further reduced the coverage by setting aside some of the observations. We then reconstructed the global temperatures using each method in turn. Finally, we compared the reconstructed temperatures to the observed temperatures where they are available... While infilling works well over the oceans, the hybrid model works particularly well at restoring temperatures in the vicinity of the unobserved regions."

The authors note that "While short term trends are generally treated with a suitable level of caution by specialists in the field, they feature significantly in the public discourse on climate change.""

Global warming forcasts prove accurate

Layzej Layzej writes  |  about a year ago

Layzej (1976930) writes "A recent Slashdot story noted a 1981 paper that predicted a rise in global mean temperatures and turned out to be surprisingly accurate — if a bit conservative. The guardian reports on a new paper that explores the performance of a forecast published in 1999. The new study predicted that the decade ending in December 2012 would be a quarter of degree warmer than the decade ending in August 1996 – and this proved correct to within a few hundredths of a degree. Compared to the forecast, the early years of the new millennium were somewhat warmer than expected. More recently the temperature has matched the level forecasted very closely" This relative slowdown has caused some journalists to speculate that global warming may have stopped. This paper shows that this is not the case. The author of the paper, Myles Allen, notes: "Of course, we should expect fluctuations around the overall warming trend in global mean temperatures (and even more so in British weather!), but the success of these early forecasts suggests the basic understanding of human-induced climate change on which they were based is supported by subsequent observations.""

Paper on conspiratorial thinking invokes conspiratorial thinking

Layzej Layzej writes  |  about a year and a half ago

Layzej (1976930) writes "Last summer a paper investigating the link between conspiratorial thinking and the rejection of climate science provoked a response on blogs skeptical of the scientific consensus that appeared to illustrate the very cognitive processes at the center of the research. This generated data for a new paper titled "Recursive fury: Conspiracist ideation in the blogosphere in response to research on conspiracist ideation" The researchers reviewed the reactions for evidence of conspirational thinking including the presumption of nefarious intent, perception of persecution, the tendency to detect meaning in random events, and the ability to interpret contrary evidence as evidence that the conspiracy is even greater in scope that was originally believed. Some of the hypotheses promoted to dismiss the findings of the original paper ultimately grew in scope to include actors beyond the authors, such as university executives, a media organization, and the Australian government. It is not clear whether the response to this paper will itself provide data for further research, or how far down this recursion could progress. I fear the answer may be "all the way""

2012 another record-setter, fits climate forecasts

Layzej Layzej writes  |  about a year and a half ago

Layzej (1976930) writes "Fox News reports: In 2012 many of the warnings scientists have made about global warming went from dry studies in scientific journals to real-life video played before our eyes. As 2012 began, winter in the U.S. went AWOL. Spring and summer arrived early with wildfires, blistering heat and drought. And fall hit the eastern third of the country with the ferocity of Superstorm Sandy. Globally, five countries this year set heat records, but none set cold records. 2012 is on track to be the warmest year on record in the United States. Worldwide, the average through November suggests it will be the eighth warmest since global record-keeping began in 1880 and will likely beat 2011 as the hottest La Nina year on record. America's heartland lurched from one extreme to the other without stopping at "normal." Historic flooding in 2011 gave way to devastating drought in 2012. But the most troubling climate development this year was the melting at the top of the world. Summer sea ice in the Arctic shrank to 18 percent below the previous record low.
These are "clearly not freak events," but "systemic changes," said climate scientist Stefan Rahmstorf of the Potsdam Institute in Germany. "With all the extremes that, really, every year in the last 10 years have struck different parts of the globe, more and more people absolutely realize that climate change is here and already hitting us.""

Report: Climate change behind rise in weather disasters

Layzej Layzej writes  |  about 2 years ago

Layzej (1976930) writes "A new report by reinsurance company Munich Re finds that North America has been most affected by weather-related extreme events in recent decades. The study shows a nearly quintupled number of weather-related loss events in North America for the past three decades, compared with an increase factor of 4 in Asia, 2.5 in Africa, 2 in Europe and 1.5 in South America. Anthropogenic climate change is believed to contribute to this trend, though it influences various perils in different ways. Climate change particularly affects formation of heat-waves, droughts, intense precipitation events, and in the long run most probably also tropical cyclone intensity. Even after adjusting for population spread and increased property values, Munich Re still says there were significant increases in the costs of weather disasters. At the same time non-climatic events (earthquakes, volcanos, tsunamis) have hardly changed. Some have cautioned that thirty years is not an appropriate length of time for a climate analysis, however the findings are consistent with expectations set out in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) as well as in the special report on weather extremes and disasters (SREX)."

The Motivated Rejection of Science

Layzej Layzej writes  |  about 2 years ago

Layzej (1976930) writes "New research to be published in a forthcoming issue of Psychological Science has found that that those who subscribed to one or more conspiracy theories or who strongly supported a free market economy were more likely to reject the findings from climate science as well as other sciences. The researchers, led by UWA School of Psychology Professor Stephan Lewandowsky, found that free-market ideology was an overwhelmingly strong determinant of the rejection of climate science. It also predicted the rejection of the link between tobacco and lung cancer and between HIV and AIDS. Conspiratorial thinking was a lesser but still significant determinant of the rejection of all scientific propositions examined, from climate to lung cancer. Curiously, public response to the paper has provided a perfect real-life illustration of the very cognitive processes at the center of the research."

A Conservative's Approach to Combating Climate Change

Layzej Layzej writes  |  more than 2 years ago

Layzej (1976930) writes "Law professor Jonathan H. Adler writes that even if the contrarians are right, and global warming ends up on the lower end of the projections, it will still produce property rights violations — an idea that is antithetical to Libertarian philosophy. Critical of the current EPA regulations and of cap and trade legislation, Adler proposes four conservative approaches to combating climate change including technology inducement prizes, reducing procedural barriers to the development and deployment of alternative technologies, and adopting a revenue-neutral carbon tax. This last point is gaining traction among republican thought leaders who feel that we have a fundamentally backward system in the United States that imposes taxes on things people want more of: income and jobs. At the same time, the U.S. allows something we want less of — carbon dioxide pollution — to be emitted without penalty."

Canadian scientists muzzled by government

Layzej Layzej writes  |  more than 2 years ago

Layzej (1976930) writes "Prior to the International Polar Year 2012 conference in Montreal, Canadian government scientists were warned not to talk to the media without governmental supervision. The message sent to scientists was clear: Big Brother is watching you. This is one of several recent examples where the Canadian government attempted to intimidate scientists into not saying anything that might be considered “off-message”. But worrying about what might or might not be off-message is not the responsibility of a scientist. Scientists should only worry about being honest about their data and how to best communicate their findings. If those findings happen to go against government policy, that should never be a scientist’s problem."

Last bastion for climate dissenters crumbling.

Layzej Layzej writes  |  more than 2 years ago

Layzej (1976930) writes "The New York Times reports: "For decades, a small group of scientific dissenters has been trying to shoot holes in the prevailing science of climate change, offering one reason after another why the outlook simply must be wrong." Initially they claimed that weather stations exaggerated the warming trend. This was disproven by satellite data which shows a similar warming trend. Next solar activity was blamed for much of the warming. This looked like a promising theory until the 80's when solar output started to diverge from global temperatures. Now, climate contrarians are convinced that changes in cloud cover will largely mitigate the warming caused by increased CO2. The New York Times examines how even this last bastion for dissenters is crumbling. Over the past few years, Several papers have shown that rather than being a mitigating factor, changes in cloud cover due to warming may actually enhance further warming."

NASA Chief Scientist responds to ex-employees

Layzej Layzej writes  |  more than 2 years ago

Layzej (1976930) writes "Last week a fellow at the Heartland Institute, a group now notorious for their plan to subvert public science education, gathered a coalition of 49 ex-NASA employees to sign a petition urging NASA to reconsider its position on climate change. For perspective, NASA currently employes over 18,000 people, and there are likely tens of thousands of ex-employees. In their letter the group requested that NASA refrain from publishing unproven remarks. Since no theory can ever be considered proven, this appears to be an attempt to silence discussion. NASA Chief Scientist Waleed Abdalati has since responded: "Our Earth science programs provide many unique space-based observations and research capabilities to the scientific community to inform investigations into climate change... After these studies have met the appropriate standards of scientific peer-review, we strongly encourage scientists to communicate these results to the public. If the authors of this letter disagree with specific scientific conclusions made public by NASA scientists, we encourage them to join the debate in the scientific literature or public forums rather than restrict any discourse.""

30-year-old global temperature predictions close to spot-on

Layzej Layzej writes  |  more than 2 years ago

Layzej (1976930) writes "The Register reports on a 30 year old paper published in Science in 1981 that projected global mean temperatures up to the year 2100. "When the 1981 paper was written, temperatures in the northern hemispheres were declining, and global mean temperatures were below their 1940 levels. Despite those facts, the paper's authors confidently predicted a rise in temperature due to increasing CO2 emissions." The prediction turns out to be remarkably accurate — even a bit optimistic. The article concludes that the 1981 paper is "a nice example of a statement based on theory that could be falsified and up to now has withstood the test.""

Ken Cuccinelli's climate-change witch hunt

Layzej (1976930) writes ""IF VIRGINIA Attorney General Ken Cuccinelli II (R) needs examples of official waste and abuse as he runs for governor, he could cite the harassment that he conducted against climate scientist Michael E. Mann, a costly episode of government overreach that is finally over.

The state’s highest court wrote in an opinion that Cuccinelli lacked the authority to subpoena records — including e-mails, drafts and handwritten notes — from the University of Virginia involving well-known climate scientist Michael Mann’s research. Now that the Supreme Court has shut Mr. Cuccinelli down, what’s left is a range of consequences that can only hurt the commonwealth. The university had to raise nearly $600,000 for legal fees — money the cash-strapped university should have been able to use for something productive. On top of that are the public resources of the attorney general’s office that Mr. Cuccinelli wasted. Scientists in Virginia now have reason to wonder whether they will suffer similar pressure if they publish research government officials don’t like."

AAAS president "Scared to Death" of New Dark Era

Layzej (1976930) writes "Nina Fedoroff, the president of the American Association for the Advancement of Science (AAAS), recently confessed at an 8000 member strong meeting that she is scared to death "we are sliding back into a dark era." She stated that she is "profoundly depressed at just how difficult it has become merely to get a realistic conversation started on issues such as climate change or genetically modified organisms." Her remarks are backed by a recently published Union of Concerned Scientists report, that chronicles the methods used by corporate businesses to harass individual scientists, ghost-write scientific articles to raise doubts about government research, and undermine the use of science to form government policy. Discover Magazine gives specific examples such as the Heartland Institute's recently revealed plan to subvert public science education, as well as the offer by the the American Enterprise Institute of $10,000 a pop to each scientists or economists who was willing to write op-eds or essays critiquing the IPCC climate report — before it was even published. The AAAS meeting was "set against a background of an entire intellectual discipline that realises that it, and its practitioners, are now under sustained attack.""

Source of Leaked Heartland Documents Revealed

Layzej Layzej writes  |  more than 2 years ago

Layzej (1976930) writes "Scientist and journalist Peter Gleik has has admitted to leaking documents that reveal the internal strategies of the Heartland Institute.. In his statement he writes "At the beginning of 2012, I received an anonymous document in the mail describing what appeared to be details of the Heartland Institute's climate program strategy. It contained information about their funders and the Institute's apparent efforts to muddy public understanding about climate science and policy. I do not know the source of that original document but assumed it was sent to me because of my past exchanges with Heartland and because I was named in it.

Given the potential impact however, I attempted to confirm the accuracy of the information in this document. In an effort to do so, and in a serious lapse of my own and professional judgment and ethics, I solicited and received additional materials directly from the Heartland Institute under someone else's name. The materials the Heartland Institute sent to me confirmed many of the facts in the original document, including especially their 2012 fundraising strategy and budget. I forwarded, anonymously, the documents I had received to a set of journalists and experts working on climate issues."

The Guardian writes "while acts of deception cannot be condoned, it is also important to note that the documents obtained by Gleick provide an insight into how some of those groups that are fundamentally opposed to reducing emissions of greenhouse gases attempt to convey the impression that their arguments are founded on science rather than on ideology.""

Fresh round of hacked climate science emails leake

The unauthorised publication is an apparent attempt to repeat the impact of a similar release of emails on the eve of the Copenhagen climate summit in late 2009. The initial email dump was apparently timed to disrupt the Copenhagen climate talks. The lack of any emails post-dating the 2009 release suggests that they were obtained at the same time, but held back. Their release now suggests they are intended to cause maximum impact before the upcoming climate summit in Durban which starts on Monday. In a statement, the University of East Anglia said "As in 2009, extracts from emails have been taken completely out of context. Following the previous release of emails scientists highlighted by the controversy have been vindicated by independent review, and claims that their science cannot or should not be trusted are entirely unsupported""

Layzej (1976930) writes "Extreme weather, such as the 2010 Russian heat wave or the drought in the horn of Africa, will become more frequent and severe as the planet warms, the Intergovernmental Panel on Climate Change (IPCC) warns in a report released today.

Critics of the report note that “Governments have in the past considerably weakened the language of IPCC summaries for policymakers,” and that the IPCC process tends to water down even the most obvious conclusions."

Layzej (1976930) writes "The global output of heat-trapping carbon dioxide jumped by the biggest amount on record in 2010, the U.S. Department of Energy calculated. A chart accompanying the study shows the breakdown by country. The new figures mean that levels of greenhouse gases are higher than the worst case scenario outlined by climate experts just four years ago. It is a “monster” increase that is unheard of, said Gregg Marland, a professor of geology at Appalachian State University, who has helped calculate Department of Energy figures in the past. The question now among scientists is whether the future is the IPCC's worst case scenario or something more extreme."
