When James Hansen speaks, climate hawks listen. Hansen was legendary during his long career as NASA’s chief climatologist for being ahead of the curve on seeing the threat of catastrophic climate change. Now he teaches at Columbia University, and he has more bad news to deliver. According to a study conducted by Hansen and 16 coauthors, being published this week in the European Geophysical Union’s open-access journal Atmospheric Chemistry and Physics, the effects of even moderate warming on sea-level rise are worse than previously believed.
Hansen and his colleagues combined analysis of the historical record with modeling and current observation and found that the rate of oceanic ice melting in Greenland and Antarctica may exceed our expectations. As InsideClimate News explains, the scientists “analyzed how an influx of cold freshwater from the planet’s melting ice sheets will disrupt the ocean’s circulation … They concluded the influx of freshwater from melting ice sheets in modern times would essentially shut down the ocean’s circulation, causing cool water to stay in the Earth’s polar regions and equatorial water to warm up even faster.”
“The cooling mechanism is cut off, so it’s melting ice shelves,” Hansen explained in an interview with Grist. “It’s a really dangerous situation where you get melting that causes more melting.”…
The bottom line, as Slate’s Eric Holthaus writes, is that “glaciers in Greenland and Antarctica will melt 10 times faster than previous consensus estimates, resulting in sea-level rise of at least 10 feet in as little as 50 years.” A sea-level rise of 10 feet would inundate parts of major cities from New York to Shanghai…
Hansen, despite his reputation for doomsaying, remains hopeful about the prospects for fending off the worst of climate change. The biggest emitting nations are not pledging to cut emissions enough to even keep warming below 2C, but Hansen says a gradually rising global carbon fee could change that. It could force emissions to drop several percentage points per year and hold us down to 1.5C in warming. To get this outcome from the messy global climate treaty process would be fantastic, but it is highly unlikely. Hansen sort of admits this, but holds out hope nonetheless.
“I don’t think it’s impossible that you could get key players to agree to the concept of an international carbon fee,” he says. “It’s not going to happen with 190 countries sitting around a table. It’s going to happen with key players negotiating directly either at Paris or in the years ahead.” Specifically, Hansen imagines that the world’s two biggest economies and biggest carbon emitters, the U.S. and China, would negotiate a carbon fee bilaterally and then use their global buying power to force all of their trading partners to join.
People who actually read and study agree. At least economists who earn a living in the world of business and finance – as well as academia. I happened to see Peter Orszag on Bloomberg Surveillance, the other morning, and he was working at advancing the Hansen solution as practical and possible. Hoping against hope that reasonable leaders of industrial nations might engage in bilateral negotiations and treaties to force the reduction in atmospheric carbon.
No, he didn’t hold out any hope for the United States offering world leadership unless anti-science conservatives were absent from both houses of Congress and the White House. Poisonally, I don’t think Americans are well-enough informed or yet free enough of medieval hobgoblins to bring about that quality of change.
Globally 90% of the excess heat caused by the rise in greenhouse gas emissions is absorbed by the oceans. The warming of the oceans due to climate change is now unstoppable after record temperatures last year, bringing additional sea-level rise, and raising the risks of severe storms, say US government climate scientists…
The annual State of the Climate in 2014 report [really big .pdf], based on research from 413 scientists from 58 countries, found record warming on the surface and upper levels of the oceans, especially in the North Pacific, in line with earlier findings of 2014 as the hottest year on record.
Global sea-level also reached a record high, with the expansion of those warming waters, keeping pace with the 3.2 ± 0.4 mm per year trend in sea level growth over the past two decades…
Scientists said the consequences of those warmer ocean temperatures would be felt for centuries to come – even if there were immediate efforts to cut the carbon emissions fuelling changes in the oceans.
“I think of it more like a fly wheel or a freight train. It takes a big push to get it going but it is moving now and will contiue to move long after we continue to pushing it,” Greg Johnson, an oceanographer at Noaa’s Pacific Marine Environmental Laboratory, told a conference call with reporters.
“Even if we were to freeze greenhouse gases at current levels, the sea would actually continue to warm for centuries and millennia, and as they continue to warm and expand the sea levels will continue to rise,” Johnson said…
The report underlined 2014 as a banner year for the climate, setting record or near record levels for temperature extremes, and loss of glaciers and sea ice, and reinforcing decades-old pattern to changes to the climate system.
Four independent data sets confirmed 2014 as the hottest year on record, with much of that heat driven by the warming of the oceans.
Globally 90% of the excess heat caused by the rise in greenhouse gas emissions is absorbed by the oceans…
“The prognosis is to expect a continuation of what we have seen,” NOAA’s Tom Karl said.
Did you expect the United States to offer the kind of effort we dedicate to killing foreigners towards saving the world, towards saving our own pitiful buns? Oh, we’ll all pretty much survive here in the GOUSA. As the largest economy in the world, we have sufficient funds, private energy and ability to accomplish a fair piece of what our government might have done if it weren’t the Orgone Box for political glory-seekers.
Now, we’ll have to work simultaneously at preserving something approaching sort-of-livable for the majority of the population – while the ruling 1% enjoy their environment-modulated mansions, employing prols to provide comfortable breezes.
The rest of the world will be on their own.
Coal is having a hard time lately. U.S. power plants are switching to natural gas, environmental restrictions are kicking in, and the industry is being derided as the world’s No. 1 climate criminal. Prices have crashed, sure, but for a real sense of coal’s diminishing prospects, check out what’s happening in the bond market.
Bonds are where coal companies turn to raise money for such things as new mines and environmental cleanups. But investors are increasingly reluctant to lend to them. Coal bond prices tumbled 17 percent in the second quarter, according to an analysis by Bloomberg Intelligence. It’s the fourth consecutive quarter of price declines and the worst performance of any industry group by a long shot.
Bonds fluctuate less than stocks, because the payoff is fixed and pretty much guaranteed as long as the borrower remains solvent. A 17 percent decline is huge, and it happened at a time when other energy bonds—oil and gas—were rising. Three of America’s biggest coal producers had the worst-performing bonds for the quarter:
Alpha Natural Resources: -70 percent
Peabody: -40 percent
Arch: -30 percent
The map shows coal plants in 2010 that may be headed for retirement. Blue circles represent plants that will be shuttered by 2020, while yellow will convert to gas, and red have undetermined futures.
About 17 percent of U.S. coal-fired power generation will disappear over the next few years, according to an analysis by Bloomberg New Energy Finance (BNEF). Obstacles include age, the abundance of cheap natural gas, and new EPA rules to cut pollution…
Even China, the world’s biggest consumer of coal, wants to be rid of it…While China’s electricity demand will soar in the coming decades, its coal use will remain relatively flat, peaking by 2030 and then declining, according to BNEF. The pollution is too thick and the alternatives too cheap for coal to flourish…
But even setting aside the environmental and health issues, renewables are on a trajectory to outcompete fossil fuels, starting with coal. Between now and 2040, two-thirds of the money spent on adding new electricity capacity worldwide will be spent on renewables, according to BNEF…
Pigs like the Koch Bros and their bed-buddies ExxonMobil et al are putting their last hopes into the Republican Party. Unlike their peers in archaic monarchies like Saudi Arabia, they have to confront minimal papier mache democracies like the United States. Conservatives like Republicans or Blue Dog Democrats needn’t involve themselves with science to decide policy. Their only decision is whether they require a new wheelbarrow to carry away the dollar$ on offer from the barons of fossil fuel – or the old one is adequate.
It only remains for the crowd in charge of the Democrat Party to decide if they will listen to reason, evidence-based science and concern for future generations of our species. For some that’s still a difficult questions.
Heavy rainfall events setting ever new records have been increasing strikingly in the past thirty years. While before 1980, multi-decadal fluctuations in extreme rainfall events are explained by natural variability, a team of scientists of the Potsdam Institute for Climate Impact Research detected a clear upward trend in the past few decades towards more unprecedented daily rainfall events.
They find the worldwide increase to be consistent with rising global temperatures which are caused by greenhouse-gas emissions from burning fossil fuels…
The average increase is 12 percent globally – but 56 percent in South East Asia
An advanced statistical analysis of rainfall data from the years 1901 to 2010 derived from thousands of weather stations around the globe shows that over 1980-2010 there were 12 percent more of these events than expected in a stationary climate, a scenario without global warming. “Due to the upward trend, the worldwide increase of record-breaking daily rainfall events in the very last year of the studied period reaches even 26 percent”, Lehmann adds.
The record-breaking anomaly has distinct patterns across Earth’s continents with generally wet regions seeing an over-proportional increase and drier regions less so. In South East Asian countries the observed increase in record-breaking rainfall events is as high as 56 percent, in Europe 31 percent, in the central US 24 percent. In contrast, some regions experienced a significant decrease of record-breaking daily rainfall events. In the Mediterranean, the reduction is 27 percent, and in the Western US 21 percent. Both regions are at risk of severe droughts.
While a statistical analysis of course cannot provide direct physical cause-effect relations, the scientists compared their findings to existing knowledge about how much more water can be stored in the atmosphere when temperatures rise, as given by the well-known Clausius-Clapeyron equation. This additional moisture can be released during short-term heavy rainfall events. The scientists show that the observed increase in unprecedented heavy rainfall events generally fits with this thermodynamically expected increase under global warming…
Up to now, studies could add up to only medium confidence on how human induced greenhouse gases have contributed to changes in heavy precipitation events at the global and regional scale. The new analysis now helps to fill this research gap. Building on previous work on extreme precipitation, it is the first to study worldwide observational data of record-breaking daily rainfall events in this context.
I probably haven’t said this for at least 10 minutes, but — if I was starting out, today, I’d point myself at a geek career in computational analysis. This stuff is fascinating. Most particularly when you have the opportunity to gather wide-reaching data and spend time data-mining, winnowing away the chaff – perhaps discovering a new direction, insight to old problems.
Drew Lessard stood on top of Folsom Dam and gazed at the Sierra Nevada, which in late spring usually gushes enough melting snow into the reservoir to provide water for a million people. But the mountains were bare, and the snowpack to date remains the lowest on measured record.
“If there’s no snowpack, there’s no water,” said Mr. Lessard, a regional manager for the Bureau of Reclamation, the federal agency that built and operates a vast network of 476 dams, 348 reservoirs and 8,116 miles of aqueducts across the Western United States.
For nearly a century, that network has captured water as it flows down from the region’s snowcapped mountains and moves to the farms, cities and suburbs that were built in the desert. But as the snow disappears, experts say the Bureau of Reclamation — created in 1902 by President Theodore Roosevelt to wrest control of water in the arid West — must completely rebuild a 20th-century infrastructure so that it can efficiently conserve and distribute water in a 21st-century warming world…
For most of the 1900s, the bureau’s system — which grew into the largest wholesale water utility in the country — worked. But the West of the 21st century is not the West of Roosevelt. There are now millions more people who want water, but there is far less of it. The science of climate change shows that in the future, there will be less still…
President Obama has already started to grapple with that change. Under orders from the White House, the Bureau of Reclamation has begun studies on the impact of global warming on 22 Western water basins and is drawing up multidecade plans to begin rebuilding its Western water management systems.
But a new water infrastructure across half of the United States could cost taxpayers billions of dollars — at a moment when Republicans are still focused on cutting taxes and lowering government spending. In Congress, the Republican majority has targeted climate change research as well as federal policies intended to stop climate change…
Sometimes the question isn’t “stupid or ignorant?” Sometimes stupid prefers ignorant.
In 1955, partly out of urgency and partly out of guilt, a group of 52 Nobel Laureates signed a declaration on Mainau Island in Germany calling for an end to the use of nuclear weapons. The work of some of these prizewinners—including that of Otto Hahn, who discovered nuclear fission—was used to build nuclear weapons. They were horrified their work was turned into technology that could kill billions.
Now, 60 years on, again out of a mix of urgency and guilt, a group of 36 Nobel prizewinners have signed a new Mainau Declaration calling for urgent action on climate change. The document is open for other Nobel Laureates to join.
The discoveries of these signatories have mostly improved the quality of life of people around the world, but they now stand horrified at the prospect of what unchecked use of natural resources could do to the future.
In our fight against climate change, another declaration—even if it’s signed by some of the most eminent living scientists—probably won’t do much. But the declaration comes at a time when world over preparations are being made for a climate-change summit to be held in Paris in November 2015. Although previous global summits have resulted in more talk and less action, there is hope that the Paris talks would be different.
One of the leaders of the 1955 Mainau Declaration was Linus Pauling, whose relentless work against nuclear weapons won him the 1962 Nobel Peace prize—putting him in the rare category of a single individual winning two Nobel prizes. Who knows? Perhaps the same could happen to one of these Nobel Laureates.
Click the link above and you’ll find the full statement from this group of scientists at the end of the article. Certainly, it will mean a great deal in the world of science. But, hey, those are just folks who advance knowledge, medicine, healthcare, technology, biology, botany, all the intellectual pursuits that brought us a modern lifespan.
It will take further action from ordinary folks like you and me to push our politicians into doing something positive in response.
Dragon lizards, that is…
The researchers, who have long studied Australia’s bearded dragon lizards, have been able to show that a reptile’s sex determination process can switch rapidly from one determined by chromosomes to one determined by temperature.
Lead author Dr Clare Holleley, a postdoctoral research fellow at the University of Canberra’s Institute for Applied Ecology, explained: “We had previously been able to demonstrate in the lab that when exposed to extreme temperatures, genetically male dragons turned into females.”
“Now we have shown that these sex reversed individuals are fertile and that this is a natural occurring phenomenon.”…
University of Canberra Distinguished Professor Arthur Georges, senior author of the paper…highlighted the importance that these discoveries have in the broader context of sex determination evolution.
“The mechanisms that determine sex have a profound impact on the evolution and persistence of all sexually reproducing species,” Professor Georges said.
“The more we learn about them, the better-equipped we’ll be to predict evolutionary responses to climate change and the impact this can have on biodiversity globally.”
Imagine how quickly our Congressional do-nothings would get off their rusty-dustys if it was determined that just a fraction of the semi-literate, obedient, party lever voters in the hotter climes of this nation were being tweaked from male to female!
We’d have a nationwide policy of carbon-reduction before you could say Koch Brother seven times in a row.
Bishop Martin Amos of the Diocese of Davenport, speaks during a news conference in Ankeny, Iowa. Roman Catholic leaders in Iowa are calling for presidential candidates to focus on the environment and income inequality in 2016.
Roman Catholic leaders in the early voting state of Iowa implored candidates for president Thursday to take up Pope Francis’ call for “profound political courage” by focusing their campaigns as much on improving the environment and income inequality as they have on opposing gay marriage and abortion in past elections.
The vocal pivot from such traditional social issues marks the first time U.S. Catholic bishops have publicly asked those seeking the White House to heed the admonitions of Francis’ June encyclical, said Bishop Richard Pates of Des Moines.
In Francis’ major teaching document, the leader of the world’s 1.2 billion Catholics called for a “sweeping revolution” to correct a “structurally perverse” economic system that allows the rich to exploit the poor and has turned the Earth into an “immense pile of filth.”
“These are going to be difficult decisions that have to be made,” said the Rev. Bud Grant of Davenport, joined at a news conference by bishops from central and eastern Iowa. “Politicians have to have the courage to do the right thing, and not necessarily the politically expedient thing.”
The push from bishops threatens to disrupt the historically reliable alliance of evangelical Christians and conservative Roman Catholic voters, putting pressure on Republicans who have leaned on their religious faith to guide them on social issues.
It will also focus attention on how the six Roman Catholics seeking the 2016 Republican presidential nomination will wrestle with a pope’s teachings on economics and climate change that clash with traditional Republican ideology.
While Francis has condemned abortion and upheld marriage as the union of a man and a woman, he has not done so with anything approaching the frequency of his two predecessors. Instead, Francis has urged church leaders to talk less about such social issues and more about mercy and compassion, so that wayward Catholics would feel welcome to return to the church.
Should be fun when Pope Francis addresses the papier mache politicians in Congress. I wonder if any of the Tea Party idjits will shout out “you lie”?
Setting aside my reflexive wryness, the Roman Catholic church remains the only significant world religion with unified – even codified – administration and leadership. As much as some of the fundamentalist sects of Protestantism in the United States work at convincing themselves they are the only true voice of their deity, any socially, politically, reasonable leader of any of these has to respect the strength of a global religious body.
The Roman Catholic church may share all of the same fears of modern times; but, the latest pope seems to have learned something about not appearing like a complete idiot in the face of reality. The question remains – will our fundamentalists learn the same lesson? Will they then rap the knuckles of their pet political party and suggest a jot of progress is more sustaining than lockstep obedience to anachronistic dogma?
NASA’s Goddard Institute for Space Studies has done a knockout series of infographics based on decades of data and study. They deserve all the credit in the world for maintaining real science in the face of superstition, myth and the new American disease – self-deception.
May 2015 was Earth’s warmest May since global record keeping began in 1880, said NOAA’s National Centers for Environmental Information…NASA rated May 2015 as the 2nd warmest May on record. May 2015’s warmth makes the year-to-date period (January – May) the warmest such period on record, according to both NOAA and NASA, and it is likely that 2015 will be Earth’s second consecutive warmest year on record. Five of the ten warmest months in recorded history have occurred in the past six months, according to NOAA:
NOAA’s top ten warmest global monthly departures from average
1) 0.89°C, Mar 2015
1) 0.89°C, Feb 2015
3) 0.88°C, Jan 2007
4) 0.87°C, May 2015
4) 0.87°C, Feb 1998
6) 0.84°C, Dec 2014
6) 0.84°C, Mar 2010
8) 0.83°C, Nov 2013
9) 0.82°C, Apr 2010
10) 0.81°C, Jan 2015
Global ocean temperatures during May 2015 were the warmest on record, and global land temperatures were tied for warmest on record. Global satellite-measured temperatures in May 2015 for the lowest 8 km of the atmosphere were the 5th or 4th warmest in the 37-year record, according to the University of Alabama Huntsville and Remote Sensing Systems, respectively.
Departure of temperature from average for May 2015, the warmest May for the globe since record keeping began in 1880. Record warmth occurred across most of Alaska, parts of tropical South America, much of southern Africa and The Middle East, and parts of northwestern Siberia. Only part of the central United States, far west central Australia, Iceland, and part of Far East Russia observed temperatures characterized as “cooler than average” for May.
Please RTFA for lots more detail. Visiting here and reading the sources I try to reference for information on climate change puts you a couple of lightyears ahead of the papier mache, let’s-pretend-to-be-skeptics that populate the sites of conservative know-nothings who most of all fear diminishing margins for fossil fuel profiteers.
