Even the greenest, most eco-friendly politicians rarely utter the words Gov. Jerry Brown spoke at the Vatican’s climate change symposium last week.

To prevent the worst effects of global warming, one-third of the world’s known oil reserves must remain in the ground, Brown told the gathering of government officials from around the world. The same goes for 50 percent of natural gas reserves and 90 percent of coal.

“Now that is a revolution,” Brown said. “That is going to take a call to arms.”

It’s an idea widely embraced among environmentalists and climate scientists. Burn all the world’s known fossil fuel supplies — the ones already discovered by energy companies — and the atmosphere would warm to truly catastrophic levels. Never mind hunting for more oil.

But it’s a concept few politicians will touch. That’s because it raises a question no one wants to answer: Whose oil has to stay put?

“They’ve all got their own oil,” said environmental activist and author Bill McKibben, who first popularized the issue with a widely read 2012 article in Rolling Stone. “Recognizing that you’ve got to leave your own oil — and not somebody else’s — in the ground is the next step.”

Take California.

No state has done more to fight global warming. By 2020, under state law, one-third of California’s electricity must come from the sun, the wind and other renewable sources. Brown wants 50 percent renewable power by 2030 and has called for slashing the state’s oil use in half by the same year.

But he has shown no interest in cutting the state’s oil production. He has touted the economic potential of California’s vast Monterey Shale formation, whose oil reserves drillers are still trying to tap. And he has steadfastly refused calls from within his own party to ban fracking.

“If we reduce our oil drilling in California by a few percent, which a ban on fracking would do, we’ll import more oil by train or by boat,” Brown told “Meet the Press.” “That doesn’t make a lot of sense.”

California remains America’s third-largest oil producing state, behind Texas and North Dakota. The industry directly employs 184,100 Californians, helps support an estimated 271,840 other jobs and yields $21.2 billion in state and local taxes each year, according to the Los Angeles County Economic Development Corporation.

‘Phasing out oil drilling’

Any governor, no matter how environmentally minded, would have a hard time turning that down. Even if many environmentalists wish Brown would.

“Just like we have a plan for increasing renewables, we need a plan for phasing out oil drilling in California,” said Dan Jacobson, state director for Environment California.

It’s difficult for politicians to even talk about something as stark as putting limits on pumping oil, he said.

“Solar and wind and electric cars are really hopeful things, whereas keeping oil in the ground sounds more like doomsday,” Jacobson said.

And yet, Jacobson, McKibben and now apparently Brown are convinced that most fossil fuel reserves must never be used.

The percentages Brown cited come from a study published this year in the scientific journal Nature. The researchers calculated that in order to keep average global temperatures from rising more than 2 degrees Celsius — 3.6 degrees Fahrenheit — above preindustrial levels, the world’s economy can pump no more than 1,100 gigatons of carbon dioxide into the atmosphere between 2011 and 2050. Burning the world’s known fossil fuel reserves would produce roughly three times that amount, they wrote.

Most governments pursing climate-change policies have agreed to aim for a 2-degree Celsius warming limit, although many scientists consider that dangerously high. So far, global temperatures have warmed 0.8 degrees Celsius from preindustrial times.

“The unabated use of all current fossil fuel reserves is incompatible with a warming limit of 2 degrees Celsius,” the study concludes.

Nonetheless, states, countries and companies with fossil fuel reserves all have an obvious and powerful incentive to keep drilling.

The market value of oil companies, for example, is based in part on the size of their reserves and their ability to find more. Activist investors warning of a “carbon bubble” in their valuations have pushed the companies to assess how many of those reserves could become stranded assets if they can’t be burned. The companies have resisted.

President Obama, meanwhile, has made fighting climate change a key focus of his presidency, raising fuel efficiency standards for cars, pumping public financing into renewable power and pushing for cuts in greenhouse gas emissions from power plants.

Cut demand or cut supply

But Obama has also boasted about America’s surging oil and natural gas production — and tried to claim credit for it. Last week, his administration gave Royal Dutch Shell the green light to hunt for oil in the Arctic Ocean. Keeping oil in the ground does not quite square with his “all of the above” energy policy, observers note. At least, not American oil.

“The same government that is working very hard to get a Clean Power Plan is allowing Shell to go exploring for hydrocarbons in the middle of nowhere, oil that may never be producible,” said climate activist and former hedge fund executive Tom Steyer, with audible exasperation.

He notes that Obama, Brown and other politicians intent on fighting climate change have focused their efforts on cutting the demand for fossil fuels, rather than the supply. Most of the policies that climate activists want to see enacted nationwide — such as placing a price on emissions of carbon dioxide and other greenhouse gases — would do the same, ratcheting down demand rather than placing hard limits on fossil fuel production.

“The political thinking is the market itself will take care of figuring out which fossil fuels have to stay in the ground,” Steyer said.

Some climate fights, however, have focused on supply. And again, the issue of whose fossil fuels have to stay put has played a part.

Opponents of the Keystone XL pipeline extension, for example, see blocking the project — which would run from Canada to America’s Gulf Coast — as a way to stop or at least slow development of Alberta’s enormous oil sands. James Hansen, the former head of NASA’s Goddard Institute for Space Studies, famously declared that fully developing the sands would be “game over for the climate.”

Obama has delayed a decision on the pipeline for years. Given America’s own rising oil production, rejecting a project that could be a boon for the Canadian economy would be difficult, analysts say.

“The message would be, ‘We’re not going to help you develop your resources — we’ll essentially raise the cost,’” said UC Berkeley energy economist Severin Borenstein. He is convinced that Canada will develop the tar sands, regardless.

“It’s become such a huge symbol that it’s impossible for Obama to make a decision on it,” Borenstein said. “I think he’s just going to run out the clock.”

Fossil Fuel Emissions Messing Up Radiocarbon Dating, Making The World Appear Older

Fossil Fuel Emissions Are About To Throw Carbon Dating All Out Of Whack

Those concerned with climate change spend a lot of time arguing that it’s not just an environmental problem, but also an economic, human rights, national security, and even mental health issue. Now a new study has found that greenhouse gas emissions could impact a range of unlikely fields due to their effect on radiocarbon dating, a much-heralded scientific method used to determine the age of objects containing organic material.

The study, published Monday in the Proceedings of the National Academy of Sciences, found that emissions from fossil fuels are artificially raising the carbon age of the atmosphere, which makes objects today seem much older than they are when scrutinized by a radiocarbon dater. This change in the ability to date objects could impact measurements commonly taken in a broad range of endeavors, including archaeology, forgery detection, forensics, earth science, and physiology.

For instance, the study suggests that by 2050 — just 35 years from now — new clothes could have the same radiocarbon date as something worn during the Battle of Hastings in 1066.

We already knew fossil fuel emissions were messing with our future, but now they might be messing with our future’s history. This is happening because carbon dating measures the percentage of carbon-14 versus non-radioactive carbon (C) found in an object to determine how long it has been around. Fossil fuels like coal and oil have been around for so long — millions of years — that all of their carbon-14, which has a half life of 5,730 years, is already decayed and gone. A half life is the period of time that it takes half a sample to decay.

As fossil fuel emissions mix into the atmosphere, they mix up the atmosphere’s carbon-14 balance by flooding it with non-radioactive carbon.

The carbon-14 in the atmosphere is absorbed by plants through photosynthesis, and when animals consume the plants they ingest it. So carbon-14 is found in all organic matter and has been used to figure out the age of thousands of artifacts since it first came into popular use in the 1940s and ’50s. Things that can be carbon dated include wood, bone, leather, hair, pottery, iron, ice cores and a host of other objects. The Dead Sea Scrolls, Stonehenge, and Ötzi the Iceman, a famous 5,500 year old mummy, were all carbon dated.

This is not the first time in modern history that carbon-14 levels have shifted. After a decrease in concentration that coincided with the Industrial Revolution, nuclear weapons testing caused a sharp rise in the middle of the 20th Century. Since then, observations show carbon-14 levels have been dropping, and they are now approaching a pre-industrial ratio, according to the press release for the study.

Carbon dating has suffered from artificial manipulation due to human impacts since it was discovered; not only from fossil fuel burning and nuclear detonations, but also agricultural chemicals that contaminate dating. It is known to be a form of science with a large margin of error. The issue now is just how large that error could become over a short amount of time.

As Gizmag reports, this variability has made it so that anything within 300 years of 1950 is considered modern according to radiocarbon dating protocol. However, if this study is correct, that 300-year margin of error could exceed 2,000 years by the end of the century.

“If we are adding non-radioactive carbon and that’s what’s happening with fossil fuels, we get this dilution effect,” Heather D. Graven, a physicist at the Imperial College London and author of the study, told the BBC.

Graven said that at current rates of fossil fuel emissions, increases in non-radioactive carbon could start to impact carbon dating by 2020. She also said there is still time to curtail this effect.

“If we reduce emissions rapidly we might stay around a carbon age of 100 years in the atmosphere, but if we strongly increase emissions we could get to an age of 1,000 years by 2050 and around 2,000 years by 2100,” she said. “If we reduced fossil fuel emissions, it would be good news for radiocarbon dating.”

So, add carbon dating to the list of reasons to mitigate greenhouse gas emissions.

Dutch government loses world’s first climate liability lawsuit

Dutch court orders government to do more to fight climate change

Éanna Kelly, Science|Business, June 25, 2015
Verdict in world’s first climate liability case says current targets are “unlawful” and the Dutch State must reduce emissions by 25% within five years

In a landmark decision, a court in the Netherlands has ordered the Dutch government to up its fight against climate change, after judges ruled that plans to cut emissions by just 14-17 per cent compared to 1990 levels by 2020 were unlawful, given the threat posed by climate change.

Legal advocate Roger Cox (L) celebrates milestone victory

The district court in The Hague said that by 2020, the Netherlands must cut CO2 emissions by 25 per cent from 1990 levels, in what was the first climate liability suit brought under human rights and tort law.

The verdict said, “The state should not hide behind the argument that the solution to the global climate problem does not depend solely on Dutch efforts … Any reduction of emissions contributes to the prevention of dangerous climate change and as a developed country the Netherlands should take the lead in this.”

The case was brought in 2102 by Urgenda (from ‘urgent’ and ‘agenda’), a class-action group of 886 concerned citizens, accusing the government of not doing enough to meet international obligations to tackle greenhouse gas emissions.

“All the plaintiffs are overjoyed by the result. This makes it crystal clear that climate change is a huge problem that needs to be dealt with much more effectively, and that states can no longer afford inaction,” said Marjan Minnesma, one of the plaintiffs.

The Dutch are lagging in terms of greening the economy. In 2012, the share of renewable energy in the Netherlands was 4.5 percent according to Eurostat, well below the EU average of 14.1 percent. Only Malta, Luxembourg and the UK have lower shares.

The inspiration behind the case was Roger Cox, a Dutch lawyer and advocate who wrote a book called ‘Revolution Justified’, in which he argued that the legal community should become much more active in the fight against climate change, given the seeming inaction of politicians.

The government has the option to appeal, although it has not said yet whether it would.

An almost identical challenge is being pursued in Belgian courts, where campaigners hope there will be ripples from the Dutch verdict.

Dutch government loses world’s first climate liability lawsuit

The Dutch government has lost a landmark legal case over its greenhouse gas emissions plans.

The environmental group Urgenda brought a class action suit over climate change on behalf of some 900 citizens, including children. The suit claimed that the government’s action to reduce greenhouse gas emissions is insufficient, and is therefore “knowingly exposing its own citizens to dangerous situations”.

Urgenda asked that the court in the Hague “declare that global warming of more than 2 °C will lead to a violation of fundamental human rights worldwide”. According to the Intergovernmental Panel on Climate Change, governments must cut emissions to between 25 and 40 per cent below 1990 levels by 2020 to have a 50 per cent chance of avoiding 2 °C.  Yet European Union states have signed up for 40 per cent cuts by 2030.

Three judges agreed with the class action suit, ruling that government plans to cut emissions by 14-17 per cent compared to 1990 levels by 2020 were illegal. The ruling said: “The state should not hide behind the argument that the solution to the global climate problem does not depend solely on Dutch efforts.”

The court ordered the Dutch government to cut greenhouse gas emissions by at least 25 per cent by 2020.

Marjan Minnesma, who initiated the case in 2013, made a statement through Urgenda. “All the plaintiffs are overjoyed by the result,” she said. “This makes it crystal clear that climate change is a huge problem that needs to be dealt with much more effectively, and that states can no longer afford inaction.”

Ahead of the ruling, James Arrandale of London-based environmental law firm Client Earth said it would be groundbreaking for Urgenda to win. It would lead to similar suits in other countries, he said. A Belgian group is already on the case.

A key point, said Arrandale, is to show that governments already have legal obligations to cut emissions, regardless of the outcome of the UN climate talks. To that end, a group of international legal experts published the Oslo Principles on 30 March, which set out existing legal obligations on governments to safeguard the climate.

2015 on pace to be hottest year on record

Federal scientists say 2015 on pace to be globe’s warmest

This year is on track to be the world’s hottest on record, federal scientists said Thursday, continuing a warming trend that even Pope Francis called worrisome in a remarkable 184-page papal letter.

Three of the world’s foremost weather agencies have reported the warmest start to any year since they began keeping records, and this week’s climate report by the National Oceanic and Atmospheric Administration found yet another chart-topping month for the globe.

May was a whopping 1.6 degrees above the 20th century average, the agency reported. California experienced average temperatures in May, but other places in the U.S., including Alaska and parts of the Northeast, made history for heat.

Still, California headed into June with a record temperature for the first five months of the year, 5.1 degrees above the 20th century average and 0.1 degrees warmer than the previous high, last year.

“We don’t do predictions here, but I would not be surprised if 2015 ends up the hottest year on record,” said Deke Arndt, a climate monitoring branch chief at the NOAA. “We’re almost halfway through the year and have a sizable lead on the pack.”

Last year currently stands as the planet’s warmest.

Climate scientists attribute the long-term trend of rising temperatures largely to human-caused bumps in greenhouse gases. The El Niño pattern that emerged earlier this year, though, is helping push the mercury to the extreme, they said. El Niños typically move heat from the ocean surface of the tropical Pacific into the atmosphere.

The upside of the El Niño is that it could bring rain to the West Coast, at least if it’s a strong system. Federal scientists are not only giving the El Niño a more than 80 percent chance of hanging on through winter — the rainy season in California — but saying that the event may be moderate or strong.

“This is starting to look like a typical El Niño footprint, something we didn’t see last year at this time,” said Steve Baxter, a forecaster for the NOAA’s Climate Prediction Center.

The past four years in California have seen below-average precipitation, and rain is desperately needed. The warm temperatures that have come with 2015, however, could mean less snow, which is critical in filling reservoirs.

Pope Francis, in an unorthodox move for the Catholic Church, weighed in on global warming this week. He tied fossil fuels to the problem and prompted a cool response from many Republican presidential candidates.
