Historic high tides from supermoon and sea level rise flood the Southeast coast
https://www.washingtonpost.com/news...and-sea-level-rise-flood-the-southeast-coast/

Ocean water surged into neighborhoods on the Southeast coast on Tuesday morning during high tide, pushing gauges well beyond predicted levels. Seemingly overnight, we’ve entered an era where king tides compete with hurricanes in the water level record books.

Tuesday morning’s high tide peaked at 8.69 feet in Charleston, over a foot and a half higher than the predicted level. The highest crest on record in Charleston was 12.56 feet on Sept. 21, 1989 — the day that Hurricane Hugo made landfall in South Carolina.

The water level near Savannah, Ga., reached 10.43 feet, which was the third highest on record for the station. The top two records are 10.47 feet on Aug. 11, 1940, when a Category 2 hurricane made landfall on the Georgia and South Carolina coast, and 10.87 on Oct. 15, 1947, when Hurricane Nine made landfall in the same location.

Residents are saying Tuesday’s high tide was worse than South Carolina’s “1,000-year flood” in early October.
 
Congressman doubles down, accuses NOAA scientists of doctoring results
http://arstechnica.com/science/2015...accuses-noaa-scientists-of-doctoring-results/

Smith is clearly suggesting that the NOAA is manipulating its results to further an external agenda. Even though his office has been provided with the raw and corrected data, as well as the details of the methods and a personal accounting of the rationale behind them, he is still accusing the scientists who published the paper in Science of fudging their results. The evidence seems to consist of the fact that he did not like those results.
 
‘We Need an Energy Miracle’
Bill Gates has committed his fortune to moving the world beyond fossil fuels and mitigating climate change.
http://www.theatlantic.com/magazine/archive/2015/11/we-need-an-energy-miracle/407881/


Gates is on a solo global lobbying campaign to press his species to accomplish something on a scale it has never attempted before. He wants human beings to invent their way out of the coming collision with planetary climate change, accelerating a transition to new forms of energy that might normally take a century or more. To head off a rise in average global temperatures of 2 degrees Celsius above preindustrial levels—the goal set by international agreement—Gates believes that by 2050, wealthy nations like China and the United States, the most prodigious belchers of greenhouse gases, must be adding no more carbon to the skies.



 
A New Map of the Arctic?
http://www.newyorker.com/tech/elements/a-new-map-of-the-arctic

In the early months of 1846, a hundred and twenty-six sailors and officers, commanded by Captain John Franklin of the Royal British Navy, sailed south from their winter harbor on Beechey Island, in the Canadian Arctic. They went in search of the Northwest Passage, the fabled route connecting the Atlantic Ocean with the Pacific; what they found instead was some of the thickest sea ice in the world. Their two ships, H.M.S. Erebus and H.M.S. Terror, became trapped in Victoria Strait. After two winters on the ice, the survivors, weakened by scurvy, starvation, and lead poisoning from poorly canned goods, made a desperate break for the mainland. They died hundreds of miles from safety. Not until September of 2014 was the wreck of the Erebus discovered, at the bottom of Queen Maud Gulf; the Terror is still missing.

The Franklin expedition vanished on the cusp of the industrial age. In the course of the next century, as humanity embraced the coal-fired power plant and the internal-combustion engine, the face of the Arctic started to change in ways that could not be explained by seasonal variation. Since 1979, when scientists began using satellites to track the phenomenon, the annual minimum extent of the region’s ice coverage has fallen by more than eleven per cent each decade. Today, a study published in Nature Climate Change suggests that, in a matter of decades, the Arctic sea-ice system will have completely departed from the range of variability that would have been recognizable to Franklin and his crew. http://www.nature.com/nclimate/journal/vaop/ncurrent/full/nclimate2848.html

The new study uses daily satellite measurements and a computer model to reconstruct historic variations in the Arctic open-water season—the ice-free times of year—and to forecast future changes. By 2050, the study predicts, the entire Arctic coastline and most of the Arctic Ocean will experience sixty more days of open water than they did in 1850. By 2100, assuming that greenhouse-gas emissions continue to rise at current rates, much of the Arctic will experience a hundred and fifty more days of open water than it did in 1850. Some places that never saw open water in preindustrial times will be ice-free for at least half the year. The section of Victoria Strait that foiled the Erebus and the Terror, for instance, was ice-free for an average of twenty-five days each year in Franklin’s time; now it averages about seventy-five. By 2025, the study predicts, that number will be close to a hundred.

Where most studies of Arctic sea ice track over-all declines in the extent of ice coverage, the Nature Climate Change paper provides a newly detailed picture of the open water left behind—a forecast that is particularly useful to humans and other species now adapting to a warming Arctic. “If you’re a walrus in Alaska, or a polar bear in Hudson Bay, or a phytoplankton somewhere above a continental shelf in the Arctic, you may not be affected by the changes in over-all sea-ice extent,” Katherine Barnhart, the lead author of the study, told me. “You will be affected by changes in the number of open-water days.” More open water means less resting and breeding room for walruses, smaller and more dangerous hunting grounds for polar bears and people, and dramatic shifts in the phytoplankton blooms that form the foundation of the Arctic food web. More open water also means that more heat from the sun is absorbed by the dark, ice-free surface of the Arctic Ocean, triggering an accelerating cycle of warming that can alter ocean circulation and, in turn, the entire global climate. (Several recent studies suggest that rapid Arctic warming is affecting the behavior of the polar jet stream, freezing the U.S. East Coast and baking the West.) “Water is an enormous heat reservoir,” James White, the director of the Institute of Arctic and Alpine Research at the University of Colorado Boulder, told me. “As you open up the ocean, you’re basically putting a hot-water bottle on top of the earth.”

The current and expected changes in Arctic sea ice have sparked a flurry of international interest in new shipping routes and newly accessible reservoirs of oil, gas, and minerals. Last month, for instance, Icelandic authorities commissioned a feasibility study of a large new deep-water harbor on the country’s northeastern coast. But Lawson Brigham, a professor of geography and Arctic policy at the University of Alaska Fairbanks and a former icebreaker captain, cautions that even at the end of the century the Arctic will remain a difficult place to travel. The Canadian archipelago, where Franklin foundered, will still be full of intersecting straits and fickle ice conditions, likely not smooth enough to compete directly with more temperate routes.

Franklin and his unlucky men might have welcomed an altered Arctic, but the rest of us should be wary. Barnhart, now a postdoctoral fellow at the University of Pennsylvania, is twenty-nine years old; according to her findings, it’s very likely that the map of the Arctic will be transformed within her lifetime. “The future is very close,” she said.
 
Climate Change Kills the Mood: Economists Warn of Less Sex on a Warmer Planet
http://www.bloomberg.com/news/artic...conomists-warn-of-less-sex-on-a-warmer-planet

Climate change has been blamed for many things over the years. Never, until now, has anyone thought it was possible to see it as a kind of contraceptive.

Hot weather leads to diminished “coital frequency," according to a new working paper put out by the National Bureau of Economic Research. Three economists studied 80 years of U.S. fertility and temperature data and found that when it’s hotter than 80 degrees F, a large decline in births follows within 10 months. Would-be parents tend not to make up for lost time in subsequent, cooler months.

An extra "hot day" (the economists use quotation marks with the phrase) leads to a 0.4 percent drop in birth rates nine months later, or 1,165 fewer deliveries across the U.S. A rebound in subsequent months makes up just 32 percent of the gap.

The researchers, who hail from Tulane University, the University of California-Santa Barbara, and the University of Central Florida, believe that their findings give policymakers three major things to think about.

1. Birth rates do not bounce back completely after heat waves.

That's a problem. As summers heat up, developed countries may see already low birth rates sink even lower. Plunging birth rates can play havoc with an economy. China's leaders recently acknowledged this by ditching the longtime one-child policy and doubling the number of children couples are allowed to have. A sub-replacement U.S. birthrate means fewer workers to pay Social Security benefits for retirees, among other consequences.

2. More autumn conceptions means more more deliveries in summer.

Infants experience a higher rate of poor health with summer births, "though the reasons for worse health in the summer are not well-established," the authors write. One possibility may be "third-trimester exposure to high temperatures."

3. Air conditioning might prove to be an aphrodisiac.

Control over the climate at home might make a difference. The researchers suggest that the rise of air conditioning may have helped offset some heat-related fertility losses in the U.S. since the 1970s.

The paper's title is about as lascivious as the National Bureau of Economic Research gets: "Maybe Next Month? Temperature Shocks, Climate Change, and Dynamic Adjustments in Birth Rates." The researchers assume that climate change will proceed according to the most severe scenarios, with no substantial efforts to reduce emissions. The scenario they use projects that from 2070 to 2099, the U.S. may have 64 more days above 80F than in the baseline period from 1990 to 2002, which had 31. The result? The U.S. may see a 2.6 percent decline in its birth rate, or 107,000 fewer deliveries a year.

50 Years After Warning, No Debate in Paris on the Science
http://www.climatecentral.org/news/fifty-years-after-warning-climate-talks-19637

The 50-year anniversary of the first detailed climate change warning issued to a U.S. president is Thursday, less than a month before a historic two-week climate negotiating session begins in Paris. The golden anniversary is coinciding with a rich embrace of climate science in global negotiations.

“There are plenty of challenging issues for the negotiators, but the basic science of climate change is not one of them,” said Harvard University economics professor https://www.hks.harvard.edu/about/faculty-staff-directory/robert-stavins, an expert on the talks. “So-called climate skepticism is essentially irrelevant to the outcome.”
 
The harm Exxon Mobil has done
http://thehill.com/opinion/op-ed/259192-the-harm-exxon-mobil-has-done

It may be hard to accept, but a single company may have set back all of humanity.

Had Exxon Mobil listened to its own scientists rather than spread disinformation on climate change, the world might not have wasted three crucial decades during which global warming went from a prediction to a fact.

Rather than apologize, Exxon Mobil’s reaction to recent investigations that detail the corporation’s deception on climate science has been both profane and righteously indignant. Exxon Mobil is now denying it denied climate change.

The corporation’s actions, however, demonstrate something else entirely: An extensive and expensive campaign to deny climate science, deceive the American people about the health and environmental ruin caused by global warming, and stop action by governments to address Earth’s rapidly accelerating climate crisis.
 
Some history that led to Judith Curry hunkering down in the NOAA conspiracy theorists' bunker

Warning: I prefer to write about science rather than people. HotWhopper exists primarily to demolish the disinformation from science deniers and replace it with facts. Judith Curry is a special case. She is/was a scientist who's now made it her life's work to vilify her colleagues and spout nonsense about science. If you are uncomfortable with this sort of write up, there are plenty of other articles here at HotWhopper that might interest you. This article doesn't contain much of anything new, except for Judith's latest conspiracy theory. I've just put together some background based on material which is available on the internet, and added some commentary.

 
The Final Days of Sub-400 PPM Carbon Dioxide
http://blogs.agu.org/mountainbeltway/2015/11/09/the-final-days-of-sub-400-ppm-carbon-dioxide/

This week is probably the last time you or me or anyone now alive on planet Earth will ever see concentrations of CO2 lower than 400 ppm. Ralph Keeling published a short piece about it, here. https://scripps.ucsd.edu/programs/keelingcurve/2015/10/21/is-this-the-last-year-below-400/

Unless something fundamentally changes in our relationship with the atmosphere (such as developing and deploying effective artificial carbon sequestration), the gas’s long-term accumulation will keep rising, and the planet will keep hanging on to a little more heat than it used to the year before.

Though “400” is simply a round number with no inherent particular significance in and of itself, passing it for good seems a valid enough reason to pause for a moment and reflect on this massive thing we’re doing to our planet.

Every additional increment of CO2 is likely to be a moderately long lived addition to our atmosphere. Its heat-trapping capacity is a major force driving our climate system into new, uncharted terrain for a long time to come.

We depend on our climate.

People we will never meet on the other side of the world do, too.

Our children will depend on it.

Grasshoppers and bluebirds and rattlesnakes and whales depend on it.

Fungi depend on it.

Grasses depend on it.

Coccolithophores depend on it.

And though this should be obvious, I’ll go ahead and say it explicitly: to a greater or lesser extent, we depend on them.

Everything’s interdependent.

We all live downstream – and we’re polluting that stream.

This planet is changing, and in many ways the changed Earth won’t be as hospitable to a lot of us who evolved in more stable times.

The changed planet won’t be as comfortable for a lot of our neighbors, a lot of people we will never meet, not to mention non-human animals large, small, familiar, exotic, ecologically negligible, or ecologically essential.

As a friendly reminder, if we screw the whole system up, we have limited real estate options:

Paris climate deal will not be a legally binding treaty
http://www.ft.com/intl/cms/s/0/79daf872-8894-11e5-90de-f44762bf9896.html#axzz3rDs3ypC5

John Kerry, US secretary of state, has warned that December’s Paris climate change talks will not deliver a “treaty” that legally requires countries to cut their carbon emissions, exposing international divisions over how to enforce a deal.

The EU and other countries have long argued that the accord due to be reached next month should be an “international treaty” with legally binding measures to cut emissions. But in an interview with the Financial Times, Mr Kerry insisted the agreement was “definitively not going to be a treaty”.

He said it would contain measures that would drive a “significant amount of investment” towards a low-carbon global economy. But he stressed there were “not going to be legally binding reduction targets like Kyoto”, a reference to the 1997 Kyoto protocol, a UN climate treaty that had targets for cutting emissions that countries ratifying it were legally obliged to meet.

Delegates from 195 countries are due to finalise a new global climate accord in Paris that will replace the Kyoto treaty, which failed to stop emissions rising. The US signed but failed to ratify that treaty, largely because it did not cover China, now the world’s largest carbon polluter.

The Paris deal is supposed to cover all countries, but Mr Kerry’s comments underline the differences between the US and other nations over how to ensure it is robust enough to shift billions of dollars of investment away from fossil fuels and towards greener energy sources.

A European Commission spokeswoman on Wednesday said the commission and many nations “would like the Paris agreement to be in the form of a protocol or a treaty” which would represent “the strongest expression of political will and also for the future it provides predictability and durability”.

Privately, EU officials acknowledge the Obama administration is eager for a deal in Paris, but not one containing new, legally binding measures because these would strengthen arguments that the agreement needs approval from a hostile US Senate, which must ratify all treaties.

To that end, negotiators are trying to craft an agreement that satisfies all sides, possibly by making its rules and procedures legally binding, but not the actual targets in many of the climate pledges that nearly 160 countries have made this year for the deal.

The issue is particularly sensitive ahead of the 2016 presidential election given the chasm between the Democrats and Republicans running for the White House over the need and urgency to tackle climate change.

Some Republicans have accused Mr Obama of pushing the Paris talks in a direction that would make it easier to circumvent Congressional scrutiny, echoing a charge that has been levelled at his administration on issues ranging from the Iran nuclear deal to his approach on illegal immigration.

Mr Kerry said it was too early to tell how the Republican-controlled Congress would respond to a global deal on carbon emissions. While climate change has played a cameo role in some of the Republican presidential debates, the Paris talks have received very little attention in the US media.

“I suppose, depending on what comes out of it, they [Congress] may well try to review it in one form or another,” said Mr Kerry, who faced harsh criticism from Republicans on Capitol Hill in the wake of the Iran nuclear deal. “We don’t have a problem with [that]. I mean, it’s fine. I mean, it depends on whether it is a poison-pill effort or a genuine effort just to review it.”

Some experts have argued that while Mr Obama is making the case for a deal, there is no guarantee that his successor — assuming it is a Republican climate-change sceptic — would not walk away from a Paris agreement.

Mr Kerry dismissed those concerns by arguing that the Republicans had “eliminated themselves from contention in the general election” because of their approach during the campaign on issues such as climate change.

Mr Kerry said several hurdles remained to securing a deal, including ensuring the US and other developed nations firmly agree to come up with the money they have promised developing countries to help combat climate change.

The Vietnam war veteran was speaking after a visit to the USS San Antonio, a transport ship at Norfolk naval base on the Atlantic coast where he sought to reinforce the case for tackling climate change. The naval base, which is the biggest in the world, is facing threats from rising sea levels and flooding.

During a speech at nearby Old Dominion University, Mr Kerry said the threat from rising temperatures was not just the “harm that is caused to the habitat for butterflies or polar bears as some people try to mock it” but the threat to everything from agriculture to national security.

“Long story short, climate change is not just about Bambi. It’s about all of us in very personal and important ways,” he told students, military officers and climate.

The task Mr Obama has given Mr Kerry in Paris is a formidable one but in the interview with the FT he argued that other countries should not worry about US politics and the chance that a Republican president could walk away from any deal reached in Paris.

“There’s just a very different electorate in the general election and I think that people will want somebody who understands climate change . . . and wants to do something about it,” the former presidential candidate told the FT.

In his speech he had also pushed back against the argument that tackling climate change was bad for the economy, saying that “four times as many Americans are employed by renewable-energy companies today than are employed by the fossil-fuel industry”.

Mr Kerry acknowledged in the interview that Congress was making it hard for the US to come up with the $3bn that it has pledged ahead of the Paris deal to help developing countries combat global warming. He attributed this to “attitudes about climate change itself” and an “ideological barrier to any kind of federal expenditure that’s dealing with a kind of global issue”.

He said finding the money was a wider challenge as “the politics of moving on climate change in many countries are trumped by paying the pensions and filling up the potholes and doing some other things”. But he said Mr Obama would find a way to get lawmakers to approve the funding.

Mr Kerry said he thought the overall target of $100bn for the deal would be surpassed but that “whether it’s formalised or not remains to be seen”. He added that he would like the US to provide more than its current pledge of $3bn, but said “I don’t know whether it’s in the cards right now”.

“We’ll get there, because the trade-offs of the budget are such that when something is a high enough priority for a president, you have a way of getting it done, even though it’s opposed by people,” he said. “If the president is prepared to veto the budget because it hasn’t included it, you can usually find some money.”
Mr Kerry said another hurdle was resistance from countries that insist they should be compensated more because of their developing nation status.

“We have to break the old mentality . . . This is not 1992, this is not 1997, this is not the same Kyoto kind of breakdown,” said Mr Kerry. “China is an example. It’s now the world’s largest emitter and it’s the second-largest economy in the world . . . Now they’re not sitting there being the same. They’re putting up some money, they’re doing other things. It’s a great example.”

Mr Kerry rejected suggestions that the US recently pulled its punches in the South China Sea to avoid angering China before Paris. Several US officials told the FT recently that the White House forced the US navy to take the least aggressive option on the table when it conducted freedom of navigation operations in the area. Asked whether the US action would make China less co-operative, Mr Kerry said “I hope not and I don’t think so”.

“First of all, we’re not being aggressive in the least. We’re doing what we’ve done for 20 years,” he said. “If anything is aggressive, putting fighter jets on a man-made island in the South China Sea is pretty aggressive, and saying you’re not militarising”.

While he praised China for its role in the talks, he raised concern about other countries, including India, which he suggested was more resistant even as he applauded Narendra Modi, its prime minister.

“India has been more cautious, a little more restrained in its embrace of this new paradigm, and it’s a challenge,” he said. “We’ve got a lot of focus on India right now to try to bring them along. ”

Mr Kerry said India was “regrettably” talking about using its own domestically produced coal — which is dirtier than some imported coals — which he said was “not the direction that we ought to be moving in”.

But conscious of putting too much pressure on countries that believe the US and developed nations should take more responsibility for the current level of greenhouse gases, the top US diplomat said, “we have to be careful not to be holier-than-thou or accusatory”.
 
G20 nations must switch big subsidies from fossil fuel to renewables-report
http://www.reuters.com/article/2015/11/12/oil-climatechange-subsidies-idUSL8N1354OM20151112


G20 members are spending $452 billion a year subsidising fossil fuel production - nearly four times global spending on renewable energy subsidies - despite pledging to phase out fossil fuel support to tackle climate change, a new report said on Thursday.

Global subsidies for renewable energy production amount to just $121 billion a year, the Overseas Development Institute (ODI), a UK-based think-tank, and research group Oil Change International said in their report.

The much greater support given to fossil fuels than to clean energy technologies by the G20, the world's biggest economies, makes it harder to cut greenhouse gas emissions and slow climate change, said the report issued before the G20 summit in Antalya, Turkey, on Nov. 15-16.
