James Hansen: Green New Deal is ‘nonsense’


Climate movement grandpa James Hansen says the Green New Deal is ‘nonsense’


24 April, 2019
In the 1980s, NASA scientist James Hansen brought climate change to the attention of Congress, and shortly thereafter the public. Humans, he testified in 1988, were responsible for rising global temperatures.
But the man who put his reputation on the line to alert the world to the dangers of global warming doesn’t appear to agree with the most recent crop of climate advocates.
In April 20 debate with Sunrise Movement’s Varshini Prakash and Christian Aid’s Amanda Mukwashi, Hansen called the Green New Deal “nonsense.”
Hosted by Al Jazeera, the 12-minute debate highlights a growing fault line between two theories of climate action. Among progressives and environmental justice advocates, the Green New Deal represents a last-ditch, economy-wide overhaul. Hansen, on the other hand, seems to argue for a more economically incremental approach that is centered on a carbon tax.
That tension came to a head when Hansen appeared visibly aggravated by the progressive proposal and Prakash, realizing that one of the most prominent climate scientists in the world was scoffing at her organization’s central focus, could only laugh in disbelief.


Although Hansen is a proponent of using technology to bring down emissions, a carbon tax, he said, “is the underlying policy required. People need energy, we need to make the price of fossil fuels include their cost to society.”
The green new dealers, on the other hand, think their predecessors are offering too little too late. Prakash referenced a “point of no return” during the debate, a threshold past which temperatures rise so much that they trigger a series of unstoppable and catastrophic feedback loops. That kind of outcome can only be stopped by drastic action, she argued. When I spoke to Sunrise’s Evan Weber late last year, he indicated that the organization wasn’t actively pursuing a carbon tax.
What was most striking about Hansen’s argument was his measured tone, a stark difference from the way even the typically staid scientists behind the U.N’s IPCC report are beginning to discuss the issue.
“We should be phasing down emissions now,” he said, which seems like a bit of an understatement considering he’s been advocating for decreased emissions for the last, oh, four decades. “If we do that, we will get a little bit warmer than we are now, and then temperature(s) can begin to decline,” he said, adding that we will have to phase out fossil fuels over the “next several decades” in order to accomplish this goal.

Tim Bob: James Hansen Mashup


None of us take any pleasure from bagging Dr James Hansen or the liar Michael Mann but the evidence is clear. I find it reprehensible that Hansen continues to dump the responsibility for cleaning up this irreversible disaster on the youth.

Setting them an unachieveable goal is callous and cruel.

The myth of the 'new technology' saving the world

 Robertscribbler and his ilk are pretending that Tesla cars are going to save the world. All nonsense, of course.

The world is going to hell in a handbasket – WITHOUT TRUMP
Teslas may produce as much CO2 as gasoline powered cars

Teslas may produce as much CO2 as gasoline powered cars

28 June, 2018

Touted by some as the planet’s greenest vehicles, electric Teslas may be as bad for the environment as traditional petrol and diesel cars, the latest research reveals.

According to researchers at the UK-based climate data provider Engaged Tracking, the production of Tesla cars, as well as fossil fuel-powered plants used for generating electricity to charge the vehicles produce nearly the same amount of emissions that conventional engines do.

Engaged Tracking analysts used a different approach to studies that usually produce favorable results for electric vehicles. They explored the total emissions generated during the construction process of a Tesla Model S instead of counting how much CO2 is produced by the vehicle during its lifecycle. The astonishing results show that a Tesla is not cleaner to run than any other petrol car in Britain.

“The annual emissions of a UK car is 1.5 tons of carbon dioxide, based on an average of 7,800 miles a year,” the research firm’s chief analyst Jonathan Harris told The Sunday Times. “Both the Tesla Model S vehicles we analyzed have the same emissions as an ordinary petrol car of 1.5 tons of CO2 per year.”

The researcher also compared Tesla Model S to the BMW i3, which is smaller and produces an annual emission equivalent of 1.3 tons of CO2, making it 15 per cent more efficient than the Tesla Model S.

According to Tesla, the comparison between the Model S and an average car was not fair, because the Tesla was much larger. The company said that the BMW i3 should be compared to its smaller car - the Model 3, while Model S should compete with such a vehicle as the Mercedes S-Class S500. Tesla claims Mercedes produces nearly 300 percent more emissions than its Model S.

“It makes no sense to compare Model S to the average annual emissions figure for cars in the UK, because that average includes a lot of smaller models that are dissimilar to Model S,” the company said as quoted by the media. “'Any fair analysis shows that electric vehicles like Model S and Model 3 generate far less CO2 per mile than any comparable gas-powered car.”

What do you get when you take a wildfire-prone cauldron of violence, political antipathy, racial, class and gender hostility and add flamethrowers to the mix?

You get Elon Musk’s marketing gimmick/financing plan to save Los Angeles.

Musk, you see, wants to build a series of tunnels underneath Los Angeles in an effort to alleviate the city’s admittedly horrendous traffic woes. To raise funds and awareness for this plan, Musk has decided to make and sell futuristic-looking flamethrowers.

Doing well, "saving the world" aren't we? Lol

THIRTY YEARS LATER...WHAT HAS CHANGED?


THIRTY YEARS AGO, while the Midwest withered in massive drought and East Coast temperatures exceeded 100 degrees Fahrenheit, I testified to the Senate as a senior NASA scientist about climate change. I said that ongoing global warming was outside the range of natural variability and it could be attributed, with high confidence, to human activity — mainly from the spewing of carbon dioxide and other heat-trapping gases into the atmosphere. “It’s time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here,” I said.

This clear and strong message about the dangers of carbon emissions was heard. The next day, it led the front pages of newspapers across the country. Climate theory led to political action with remarkable speed. Within four years, almost all nations, including the United States, signed a Framework Convention in Rio de Janeiro, agreeing that the world must avoid dangerous human-made interference with climate.

Sadly, the principal follow-ups to Rio were the precatory Kyoto Protocol and Paris Agreement — wishful thinking, hoping that countries will make plans to reduce emissions and carry them out. In reality, most countries follow their self-interest, and global carbon emissions continue to climb (see graph above).

It’s not rocket science. As long as fossil fuels are cheap, they will be burned and emissions will be high. Fossil fuel use will decline only if the price is made to include costs of pollution and climate change to society. The simplest and most effective way to do this is by collecting a rising carbon fee from fossil fuel companies at domestic mines and ports of entry.

Economists agree: If 100 percent of this fee is distributed uniformly to the public, the economy will be spurred, GNP will rise, and millions of jobs will be created. Our energy infrastructure will be steadily modernized with clean energies and energy efficiency.

The clinching argument for a carbon fee, as opposed to ineffectual cap-and-trade schemes dreamed up by politicians, is that the fee can be imposed almost globally via border duties on products from countries that do not have a fee, based on standard fossil fuel content of the products. This will be a strong incentive for most countries to have their own fee.

Any cap approach, by contrast, leaves the impossible task of negotiating 190 caps on all the world’s nations. Governments of some countries may keep a carbon fee as a tax. However, in democracies uniform 100 percent distribution of the funds will be needed to achieve public support.

A carbon fee is crucial, but not enough. Countries such as India and China need massive amounts of energy to raise living standards. The notion that renewable energies and batteries alone will provide all needed energy is fantastical. It is also a grotesque idea, because of the staggering environmental pollution from mining and material disposal, if all energy was derived from renewables and batteries. Worse, tricking the public to accept the fantasy of 100 percent renewables means that, in reality, fossil fuels reign and climate change grows.

The United States and Europe burned most of the global carbon budget that we are permitted to burn if climate is to be stabilized. As such, we have a moral obligation to the developing world, and a practical problem, because we all live on the same planet.

Young people are puzzled that, 25 years ago, President Clinton terminated R&D on next-generation safe nuclear power, the principal alternative to fossil fuel electricity. It is not too late. My advice to young people is to cast off the old politics and fight for their future on technological, political, and legal fronts.

It will not be easy. Washington is a swamp of special interests and, because of the power of the fossil fuel industry, our political parties are little concerned about the mess they are leaving for young people.

Young people have great potential political power, as they showed in their support of Barack Obama in 2008 and Bernie Sanders in 2016. However, it is not enough to elect a leader who spouts good words. It is necessary to understand needed policies and fight for them.

The best way to fight for the carbon fee and dividend is to join Citizens’ Climate Lobby, which now has more than 90,000 members but needs more, especially young people. CCL members are appropriately polite and respectful as they cajole politicians in Washington. If they were joined by the fire of young people that was demonstrated in 2008 and 2016, even the mighty fossil fuel industry would take notice.

The fossil fuel industry afraid of kids? They might be when they notice who is standing behind the kids: the United States Constitution. Kids are people with constitutional rights to life, liberty and property.

Many lawsuits are being filed, in the United States and around the world, on behalf of young people. They include stopgap efforts, such as a suit to block the Trump administration from opening the Powder River Basin in Montana to coal exploitation (with potential to exceed US emissions of the past 50 years), and the Our Children’s Trust lawsuit, demanding government policies to reduce fossil fuel emissions at a rate that the science indicates is needed to support a healthy climate.

Chances of winning lawsuits grow as incontrovertible evidence of climate change grows. The judiciary is less subject to bribery from the fossil fuel industry than are the other branches of government. Yet in this case, justice delayed may be justice denied. Young people cannot afford the “all deliberate speed” that followed the Brown v. Board of Education decision regarding civil rights in 1954.

Young people and old people must understand the implications of the accompanying graph. The fight to phase down fossil fuel emissions is not yet being won. We all must understand needed energy policies and fight for the future of our young people. We must use all the levers of our democracy to force the fossil fuel industry to become a clean energy industry.

James Hansen interviewed by Chris Hedges

Neither Chris Hedges nor Dr. James E. Hansen are truly fessing up to the severity of the crisis.


How far over the cliff do we have to be for them to accept the reality?
--Kevin Hester

Dr. Hansen is really repeating the same message I have been hearing for a quarter of a century when the reality on the ground has changed radically.

He is still talking about sucking CO2 out of the atmosphere when we have many irreversible positive feedbacks - one being the melting of Arctic sea ice (unmentioned), the methane monster (completely ignored) and information that has been in the headlines in recent days - that drought in the Amazon and wildfires has led to the 'lungs of the planet' becoming a source of CO2, rather than a carbon sink.

I have to ask me whether this is just a matter of conscience for a scientists of this calibre, or is it something more?

James Hansen 12 years ago: ""If we pass 1°C, It's a point of no return for global warming"

The real target, as pointed out by foremost climate scientist, James Hansen has always been 1 degree Celsius. Yet if you take the sleight-of-hand out of the equation (changing the measurements from comparisons with the pre-industrial age to the oeriod since 1950) we have already passed the 1.5 degrees target mentioned at Paris.

And yet at a talk I went to recently the message was that the climate is changing in a linear manner and we are on target for a 0.1C increase per decade.


This is not only wrong but it is fraud.

From Guy McPherson: 

"According to an analysis posted on the Arctic News blog on April 24, 2017 that assumes exponential temperature rise, rather than simply adding up the primary contributors of temperature rise, the planet will reach 23 C — some 9.5 degrees above the 1750 baseline — in 2021. 

"That’s in four years. 

"Lest you believe this is crazy, a similar analysis conducted in 2012 predicted only a global-average rise in temperature of 4 C above the 1750 baseline by 2030. The analysis from 2012 has proven wildly conservative."




As James Hansen Stated in 2005, "If we pass 1°C, It's a point of no return for global warming"


Perhaps we shouldn't be speculating but these off-the-cuff calculations give an indication of where we are.


17,944 km³ losing 2041/week ~18 losing 2/week = 9 weeks from now. That's one week into August in my book. (Daily losses of course suggest even earlier in the summer.)

Using the last couple of days for average, we get this math puzzle:


17,944 km³ – 515/day = 17944/515 = 35 days. I.e. July 4th @ Zero km³.

James Hansen talks anout Greenland and Canada's fires

James Hansen on Greenland Ice and Canada’s Fires



10 May, 2016


The town of Fort McMurray, some four hundred miles north of Calgary, in Canada, grew up very quickly on both sides of the Athabasca River. During the nineteen-seventies, the population of the town tripled, and since then it has nearly tripled again. All this growth has been fuelled by a single activity: extracting oil from a Florida-sized formation known as the tar sands. When the price of oil was high, there was so much currency coursing through Fort McMurray’s check-cashing joints that the town was dubbed “Fort McMoney.”
Now Fort McMurray is burning. A forest fire that began to the southwest of the town on Sunday has forced the entire population—almost ninety thousand people—to evacuate. On Wednesday, Alberta’s provincial government declared a state of emergency. By yesterday, more than fifteen hundred buildings had been destroyed and the blaze had spread through an area covering more than three hundred square miles. It was burning so hot that that it was easily able to jump major rivers. One Canadian official described the fire as “catastrophic.” Another called it a “multi-headed monster.”
fortmac
No one knows exactly how the fire began—whether it was started by a lightning strike or by a spark provided by a person—but it’s clear why the blaze, once under way, raged out of control so quickly. Alberta experienced an unusually dry and warm winter. Precipitation was low, about half of the norm, and what snow there was melted early. April was exceptionally mild, with temperatures regularly in the seventies; two days ago, the thermometer hit ninety, which is about thirty degrees higher than the region’s normal May maximum. “You hate to use the cliché, but it really was kind of a perfect storm,” Mike Wotton, a research scientist with the Canadian Forest Service, told the CBC.
Though it’s tough to pin any particular disaster on climate change, in the case of Fort McMurray the link is pretty compelling. In Canada, and also in the United States and much of the rest of the world, higher temperatures have been extending the wildfire season. Last year, wildfires consumed ten million acres in the U.S., which was the largest area of any year on record. All of the top five years occurred in the past decade. In some areas, “we now have year-round fire seasons,” Matt Jolly, a research ecologist for the United States Forest Service, recently told the Times.
“You can say it couldn’t get worse,” Jolly added, but based on its own projections, the forest service expects that it will get worse. According to a Forest Service report published last April, “Climate change has led to fire seasons that are now on average 78 days longer than in 1970.” Over the past three decades, the area destroyed each year by forest fires has doubled, and the service’s scientists project that it’s likely to “double again by midcentury.” A group of scientists who analyzed lake cores from Alaska to obtain a record of forest fires over the past ten thousand years found that, in recent decades, blazes were both unusually frequent and unusually severe. “This extreme combination suggests a transition to a unique regime of unprecedented fire activity,” they concluded.

Record warm oceans have spawned scary slate of monster tropical cyclones
By Jason Samenow



20 April, 2016

In the past six months, the Earth has witnessed several of the freakiest, most intense storms in recorded history.

Spurred by the highest ocean temperatures observed to date, record-breaking tropical cyclones — the class of storms that includes hurricanes and typhoons — have explosively developed in three regions: the northeast Pacific Ocean, the south Pacific Ocean and the Indian Ocean.
These storms may be a harbinger of increasingly severe tropical cyclones in future decades as the Earth continues warming.
The most recent vicious storm, Tropical Cyclone Fantala, attained peak winds of 173 mph north of Madagascar this past weekend. According to meteorologist Bob Henson at Weather Underground, it became the most intense tropical cyclone on record in the Indian Ocean. Fantala has since lost some steam andis forecast to weaken to a tropical storm over the southern Indian Ocean by early next week.  Fortunately, it has avoided any land areas.
Just two months before Fantala, Tropical Cyclone Winston became the fiercest storm on record in the South Pacific, with peak winds of 185 mph. This storm devastated parts of Fiji.

And four months before Winston, Hurricane Patricia (October 2015) became the strongest storm measured to date by the National Hurricane Center in the Northeast Pacific. Its peak winds reached 215 mph before it slammed into Mexico’s west coast.

Patricia, the strongest hurricane recorded to date, near maximum intensity, Oct. 23, 2015. (NOAA)
Patricia was just one of 25 Category 4 or 5 tropical cyclones in 2015 in the Northern Hemisphere, the most on record by far.
This is not to mention November 2013’s Super Typhoon Haiyan, which became the strongest tropical cyclone in the northwest Pacific (and the Eastern Hemisphere) based on wind speed.  Its 195 mph maximum sustained winds devastated parts of the Philippines.

To be sure, because the intensity of these storms was not observed by aircraft, except for Patricia, there is some uncertainty in their exact measurements. And, the period of record in the Indian Ocean, where Fantala developed, only dates to 1990.
But all of these storms formed in areas where ocean temperatures were much warmer than normal and during an era in which ocean temperatures are warming.
The recent ocean heating provided by El Niño, particularly in the Pacific, has certainly played a role in this flare-up of intense storms. But the longer-term ocean warming trend, related to growing concentrations of greenhouse gases in the atmosphere, is very likely to be playing an important role as well.
Published studies have documented an increase in the intensity of the strongest storms in several ocean basins in recent decades, although an unambiguous global warming signal in tropical cyclone activity hasn’t emerged. Such a signal is expected to become clearer in the future.
A NOAA-led study published in September projects increases in “the number and occurrence days of very intense category 4 and 5 storms” by the end of the century, and, more generally, NOAA projects an increase in the average intensity of tropical cyclones.
Fantala, Winston, Patricia and Haiyan may portend more frequent and intense severe tropical cyclones, especially during El Niño episodes in the Pacific (in the Atlantic, more intense storms would occur during La Niñas).

Climate-change warnings include rising seas and wild weather shifts. But giant flying boulders?


Standing atop a 60-foot cliff overlooking the Atlantic, James Hansen — the retired NASA scientist sometimes dubbed the “father of global warming” — examines two small rocks through a magnifying glass. Towering above him is the source of one of the shards: a huge boulder from a pair locals call “the Cow and the Bull,” the largest of which is estimated to weigh more than 1,000 tons.

The two giants have long been tourist attractions along this rocky coast. Perched not far from the edge of a steep cliff that plunges down into blue water, they raise an obvious question: How did they get up here?

A matter of degrees: Diplomats are heading to Paris to come up with a plan for averting the worst effects of climate change. Their goal: Keep global temperatures from rising more than two degrees Celsius over preindustrial levels. But are they too late?

Compounding the mystery, these two are among a series of giant boulders arranged in an almost perfect line across a narrow part of this 110-mile-long, wishbone-shaped island.

Hansen and Paul Hearty — a wiry, hammer-slinging geologist from the University of North Carolina at Wilmington who has joined him here as a guide — have a theory about these rocks. It’s so provocative — and, frankly, terrifying — that some critics wonder whether the man who helped spawn the whole debate about the dangers of climate change has finally gone too far.

The idea is that Earth’s climate went through a warming period just over 100,000 years ago that was similar in many ways to the warming now attributed to the actions of man. And the changes during that period were so catastrophic, they spawned massively powerful superstorms, causing violent ocean waves that simply lifted the boulders from below and deposited them atop this cliff.

If this is true, the effort kicking off in Paris this week to hold the world’s nations to strict climate targets may be even more urgent than most people realize.

Hearty, an expert on Bahamas geology, first published in 1997 the idea that Cow and Bull were hurled to their perch by the sea. Since then, Hansen has given the work much added attention by framing the boulders as Exhibit A for his dire view of climate change — which has drawn doubters in the scientific community. But as Hansen examines the rocks on a recent morning, Hearty explains some of the evidence. In particular, Hearty points out that the tiny grains that constitute the boulder rocks are more strongly cemented together and less likely to crumble than other rocks nearby, a sign that the boulders are older than what’s beneath them.

“Yeah,” Hansen says with a nod, rubbing the younger rock and watching it crumble a little. He sees the difference. It’s a key point the two use to argue that the placement of these boulders indicates a dramatic hurling of the rocks by the sea. Even on a calm day, the deep blue waters of the Atlantic slam against the cliffs below with audible force and huge plumes of spray. But could waves have lifted these massive stones?

While there is a suggestion in the scientific literature that the boulders were simply left behind after surrounding rocks eroded away, Hearty and another leading Bahamas geology expert, Pascal Kindler of the University of Geneva in Switzerland, agree that the boulders are older than the surface upon which they rest and, thus, probably were moved by the sea. Even the tourist placard near here takes their side, saying the ocean “lifted them atop the ridge.” But exactly how it could have done that is another matter.

Scientists have tended to attribute odd boulders such as these to tsunamis — there’s little doubt they have the power to move large rocks. One recent study found that in the Cape Verde islands, 73,000 years ago, a 300-foot-high mega-tsunami carried boulders as large as 700 tons atop a cliff almost as high as the Eiffel Tower.

But more recent studies have also attributed large boulder movements to storms. And now into the fray has stepped Hansen, who, in 1988 testimony before Congress, put the climate issue on the map by contending — correctly, as it turned out — that global warming had already begun. If he is also right about the boulders, Earth could be in for a rough ride.


And even if not, one thing is clear: Cow and Bull present a scientific mystery whose solution may serve as a reminder of just how violent and dynamic a planet we live on...[ ]
