We just hit 410 ppm of CO2. Welcome to a whole new world. Ten years ago, Mark Magaña was a D.C. lobbyist, when the Bipartisan Policy Center hired him to rally Latino support for an ill-fated bill to limit corporate carbon emissions.

We just hit 410 ppm of CO2. Welcome to a whole new world.

As Magaña soon found, there was no network to tap. Even within green groups in Washington, most Latino environmentalists didn’t know each other. “The more I got into it, the more I saw the individuals in D.C. were very isolated,” Magaña says. “If I went to a green reception, maybe I’d be the only Latino in the room. Maybe there’d be one other, but I wouldn’t know them.” In response, Magaña founded GreenLatinos, a national network of Latino environmental advocates that connects grassroots efforts with power and money in Washington. Diversity is the future of the environmental movement, Magaña says. Les émissions mondiales de CO2 se stabilisent, mais le climat continue de s’emballer. Bonne nouvelle sur le front du climat : les émissions mondiales de CO2, le principal gaz à effet de serre relâché par les activités humaines, ont stagné en 2015, et devraient rester quasiment stables en 2016.

Les émissions mondiales de CO2 se stabilisent, mais le climat continue de s’emballer

Is it time to give up on the 350 ppm goal? We’re now consistently above 400. Just three years ago this month, the carbon dioxide monitoring station atop Hawaii’s Mauna Loa reached a significant milestone: the first measurement of CO2 concentrations that exceeded the benchmark of 400 parts per million (ppm).

Is it time to give up on the 350 ppm goal? We’re now consistently above 400.

Now, they may never again dip below it. As CO2 levels once again approach their annual apex, they have reached astonishing heights. Concentrations in recent weeks have edged close to 410 ppm, thanks in part to a push from an exceptionally strong El Niño. But it is the emissions from human activities that are by far the main driver of the inexorable climb of CO2 concentrations in the atmosphere. That trend, in turn, is driving the steady rise of global temperatures, which have set record after record in recent months. Those CO2 levels will soon begin to drop toward their annual minimum as spring triggers the collective inhale of trees and other plant life.

And before too long, that will be the case the world over. Turns out young forests are pretty great at sucking up carbon. 21 countries shrank their carbon pollution while growing their economies. There’s some handwringing even among skeptics who accept climate change is real and human-made that rising greenhouse gas emissions is the inevitable product of a growing economy.

21 countries shrank their carbon pollution while growing their economies

And for years, that was pretty much the case: The only time a country saw emissions dip was in an economic recession. But that doesn’t look to be the case any longer, particularly for industrialized nations. A new analysis from the World Resources Institute (WRI), based on data from BP and the World Bank, finds 21 countries have cut greenhouse gas emissions since 2000 but have seen their economy grow all the same. That includes the United States: The WRI analysis lends further support to a trend at the global level of decoupling emissions from economic growth. A frightening record: Carbon dioxide levels show biggest-annual jump. Recently, we’ve had more reason than usual to be optimistic on climate change — the world reached its first truly global climate agreement in December, there are a lot of signs that China is getting serious about its emissions, and coal is facing economic collapse in the U.S.

A frightening record: Carbon dioxide levels show biggest-annual jump

GCP : Global Carbon Project : Homepage. Chronique de Gérard Feldzer : La compensation carbone volontaire. The atmosphere hit 400 ppm of CO2 earlier this year. Yes, that’s terrible. In 2008, climate scientist James Hansen published a paper stating that 350 parts-per-million (ppm) is the safe upper limit of CO2 in the atmosphere before the planet really goes haywire.

The atmosphere hit 400 ppm of CO2 earlier this year. Yes, that’s terrible

Earlier this year, according to a new report from the World Meteorological Organization (WMO), the global monthly average hit 400 ppm. Uff da. Certain monitoring stations — including the classic Mauna Loa Observatory — have measured a 400 ppm monthly average before, but the WMO says that this is the first time global measurements have collectively crossed the threshold. The Washington Post reports: The WMO maintains the world’s biggest network of sensors detecting changes in the makeup of the Earth’s atmosphere. China is about to launch the world’s biggest cap-and-trade program. This story was originally published by Mother Jones and is reproduced here as part of the Climate Desk collaboration.

China is about to launch the world’s biggest cap-and-trade program

On Friday, Chinese President Xi Jinping will announce that China will start the world’s largest carbon-trading system by 2017, according to a statement released Thursday night by the White House. The announcement allows China to implement something that evaded President Barack Obama during his first term in the White House: an economy-wide reform putting a price on carbon dioxide emissions and encouraging big polluters to develop alternative ways to generate energy.

Ultimately, the program is intended to curb the planet-warming emissions that are generated by burning fossil fuels. Here’s more evidence that cutting CO2 pollution can be good for the economy. The Northeast’s cap-and-trade program generated $1.3 billion in economic benefits for participating states over the last three years.

The Regional Greenhouse Gas Initiative (RGGI) also created an estimated 14,200 years’ worth of full-time employment between 2012 and 2014, and it cut residents’ electricity and heating bills by a total of $460 million. That’s according to a new analysis by a group that is creatively named Analysis Group, one of the largest economic consulting firms in the country. In addition to spurring the economy in the participating states — Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont (Chris Christie pulled New Jersey out) — the system is succeeding at its primary goal: fighting climate change. CO2 emissions in participating states have fallen by about a third since 2009, when the carbon-trading system went into effect So much for the argument that cutting greenhouse gas emissions hurts the economy. Turns out the world’s first “clean coal” plant is a backdoor subsidy to oil producers. The world’s first “clean coal” plant — that is, the first full-size coal-fired power plant ever to capture and store the majority of its CO2 emissions — is located in, of all places, Saskatchewan.

(They should change the name to “Of All Places, Saskatchewan.”) According to the first financial analysis done on the project, it appears to be functioning primarily as a public subsidy to the province’s aging oil industry. These magic CO2-dissolving capsules want to save the world. The cheapest high-tech cure for our rampant CO2 levels may already grow in our own backyard, but that hasn’t stopped scientists from continuing to try to do Mother Nature one better.

These magic CO2-dissolving capsules want to save the world

Our best bet so far looks a bit like enchanted caviar (but, um, don’t eat it). These tiny silicon capsules could potentially suck carbon out of the air faster, cleaner, and more efficiently than any other technology out there — giving us a new tool to fight emissions at power plants and factory stacks. The preliminary research is detailed in a study out today in Nature Communications, from scientists at the Lawrence Livermore National Laboratory and Harvard’s School of Engineering and Applied Sciences. The secret sauce is actually a familiar ingredient: baking soda — or, technically, bicarbonate, which is the main ingredient in that household staple.

"If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current levels [398 ppm.] to at most 350 ppm " ~ Dr.

James Hansen Reversing Global Warming. Since Dr. James Hansen, a leading climatologist, warned in 2008 that we need to reduce the amount of CO2 in the Earth's atmosphere to 350 parts-per-million (ppm) in order to preserve life on Earth, little has been done to get us there. It's getting late. Big corporations are getting ready for carbon taxes, even if we’re not.

When a promising cap-and-trade bill failed in the Senate in 2010, oil and coal companies everywhere must have breathed a sigh of relief, then probably wiped the sheen from their collective brow with a spare Benjamin and got back to work. Here’s what to do with all that extra CO2 you’ve got hanging around.

Newsroom. 09/10/2013 - Credible and consistent carbon pricing must be the cornerstone of government actions to tackle climate change, according to a new OECD report. Releasing the report Climate and carbon: Aligning prices and policies during a Lecture organised jointly with the London School of Economics, OECD Secretary-General Angel Gurría said that a transformation of the global energy system is needed if countries hope to limit climate change to a 2ºC temperature increase from pre-industrial levels, as agreed by the global community.

He called for a coherent approach to carbon pricing, to ensure that price signals sent to consumers, producers and investors alike are consistent and facilitate the gradual phase-out of fossil fuel emissions. He also questioned how much impact existing climate policies can have when countries around the world continue to subsidise the exploration, production and use of fossil fuels. Bloomberg LP Launches First Tool That Measures Risk of 'Unburnable Carbon' Assets. Home Page Title: Al Gore: World is on brink of “carbon bubble” The world is on the brink of the “largest bubble ever” in finance, because of the undisclosed value of high-carbon assets on companies’ balance sheets, and investment managers who fail to take account of the risks are failing in their fiduciary duty to shareholders and investors, Al Gore and his investment partner, David Blood, have said.

“Stranded carbon assets” such as coal mines, fossil fuel power stations, and petrol-fueled vehicle plants represent at least $7 trillion on the books of publicly listed companies, and about twice as much again is owned by private companies, state governments, and sovereign wealth funds. As the danger from climate change intensifies, and as rules on carbon and the introduction of carbon pricing in many parts of the world start to bite, these assets are expected to come under threat, from regulation and from the need to transform the economy on to a low-carbon footing. Al Gore: World is on brink of “carbon bubble” Carbon targets, carbon taxes, and the search for Archimedes’ lever.
