Emissions From Global Food Production Threaten To Overwhelm Efforts To Combat Climate Change

Each year our terrestrial biosphere absorbs about a quarter of all the carbon dioxide emissions that humans produce. This a very good thing; it helps to moderate the warming produced by human activities such as burning fossil fuels and cutting down forests.

But in a paper published in Nature today, we show that emissions from other human activities, particularly food production, are overwhelming this cooling effect. This is a worrying trend, at a time when CO2 emissions from fossil fuels are slowing down, and is clearly not consistent with efforts to stabilise global warming well below 2C as agreed at the Paris climate conference.

To explain why, we need to look at two other greenhouse gases: methane and nitrous oxide.

Following Sudden Death of Indicted Former Chesapeake Energy CEO, Justice Department Investigation into Collusion Continues

Last Tuesday, the Justice Department announced criminal charges against former Chesapeake Energy CEO Aubrey McClendon, stemming from an alleged lease bid-rigging conspiracy between McClendon and another unidentified oil and gas company. The felony count against McClendon carried up to a decade in prison and $1 million in fines.

Shortly after 9 AM the next day, McClendon crashed his SUV at over 50 mph into a concrete highway overpass and died instantly of blunt force trauma. Police are continuing to investigate McClendon's cause of death, awaiting toxicology results and other data, and have not ruled out the possibility that the car wreck may have been a suicide.

“He pretty much drove straight into the wall,” Oklahoma City Police Department Capt. Paco Balderrama told a local NBC affiliate. “There was plenty of opportunity for him to correct and get back on the roadway and that didn’t occur.”

The dramatic exit of one of the most flamboyant wildcatters in the shale rush stunned many observers — and his abrupt death may serve to pull attention away from the underlying crimes that McClendon was so recently accused of committing. The acts McClendon, age 56, stood accused of occurred at the height of the shale land rush and were committed in his role as then-CEO of Chesapeake Energy, the nation's second largest natural gas producer.

Before McClendon died, Forbes writer Chris Helman noticed something very interesting in the former CEO's response to his indictment: McClendon didn't deny the acts underlying the charges, he simply argued that others in oil and gas industry also engaged in the same conduct.

 Background

As Warming Accelerates, Talk Of Climate Change Dissipates

There is not a single person running for U.S. President as a Republican who believes that we should take action to fight climate change. Not one. To make matters worse, the top three contenders for the Republican nomination — Donald Trump, Ted Cruz, and Marco Rubio — refuse to even acknowledge that climate change is real. The remaining two GOP candidates — John Kasich and Dr. Ben Carson — don’t believe climate scientists about the scope and severity of the problem.
 
One of these men will have a 50% chance of becoming the President of the United States this coming November. And depending on which polls you look at, the three frontrunners have a very real shot at actually winning the election.
 
Cruz and Rubio are the only two candidates who currently serve in office, both in the Senate, and while they are currently both trailing Trump in delegate count, the number of primaries left to be held indicate that either could take the lead and secure the nomination. And since they both hold office, we can check their records to see where they stand on environmental issues.
 
And things aren’t looking good.

Scientists from 60 Countries Condemn Cuts To Vital Climate Research at Australia's CSIRO Agency

Almost 3000 scientists from more than 60 countries have condemned Australia’s key government science agency over plans that would “decimate” its climate change research capabilities.

The open letter, delivered to Prime Minister Malcolm Turnbull and his ministers on Thursday evening, warns the cuts would leave the Southern Hemisphere “with no sustainable, world-class climate modelling capability.”

Since news of the cuts at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) emerged last week, leading scientists and institutions from across the world have attacked the plans.

CSIRO chief executive Larry Marshall told staff in an email that the agency wanted to shift the focus of its Oceans and Atmosphere division away from climate change monitoring and modelling because the science of climate change was now “proved.”

His claimed justification for the cuts have been roundly criticised by current and former staff CSIRO staff members

On Thursday, Marshall joined senior CSIRO bosses in a scheduled appearance before an Australian Senate Committee, where he was grilled over the plans. Climate scientists attending a major conference in Melbourne broke off from proceedings to crowd around a televsion to watch Marshall give evidence.

New Report Identifies The Fossil Fuels We Must Keep In The Ground To Avert Catastrophic Climate Change

As the US Senate haggles over a comprehensive energy bill, climate activist groups have identified the global fossil fuel reserves that must be kept in the ground if we’re to limit global warming to the critical 2-degree-Celsius threshold.

This week saw the Senate debating the hotly contested energy bill, which has been criticized by environmentalists for including a number of fossil fuel industry giveaways, including expedited permitting for liquefied natural gas (LNG) terminals and subsidies for coal technology, among other troublesome provisions.

Democratic Senators Sheldon Whitehouse (RI), Ed Markey (MA) and Brian Schatz (HI) responded by introducing an amendment into the energy bill designed to express Congress’s disapproval of the use of industry-funded think tanks and misinformation tactics aimed at sowing doubt about climate change science.

Senate Democrats ultimately stopped the energy bill from moving forward on Thursday over the fact that a $600-million amendment to address the water crisis in Flint, MI was not included.

The US is not the only country that needs to do some soul-searching when it comes to energy policies, however.

What Are The Chances Of Getting All These Record Hot Years Without The Extra Greenhouse Gases? The Answer...

From hot to fractionally less hot, here are the planet’s ten warmest years on record – 2015, 2014, 2010, 2005, 2007, 2013, 2009, 1998, 2002 and 2006.

These are the numbers according to NASA and include measurements taken on land and at sea in a record that goes back to the year 1880.

Now that’s a pretty remarkable run of hot years for an era when, according to the rusted-on professional climate science denialists, global warming was supposed to have stopped.

But what are the chances of getting a run of “hottest on record” years like that - 14 of the 16 hottest years all happening since 2000 - without all the extra greenhouse gases that humans have been judiciously stockpiling in the atmosphere and oceans?

'The Blob' Disrupts What We Think We Know About Climate Change, Oceans Scientist Says

Deep in the northeast Pacific Ocean, The Blob is acting strangely.

When the abnormally warm patch of water first appeared in 2013, fascinated scientists watched disrupted weather patterns, from drought in California to almost snowless winters in Alaska and record cold winters in the northeast.

The anomalously warm water, with temperatures three degrees Centigrade above normal, was nicknamed The Blob by U.S climatologist Nick Bond. It stretched over one million square kilometres of the Gulf of Alaska — more than the surface area of B.C. and Alberta combined — stretching down 100-metres into the ocean.

Two Members of Lord Lawson's Climate Denial Think Tank Lose £2K In Climate Science Bet

Want to lose £2,000? Then make a bet with a climate change expert that the world isn’t warming.

That’s what two members of Lord Lawson’s climate change science denying Global Warming Policy Foundation (GWPF) did when they bet Chris Hope, a Cambridge University researcher, that 2015 wouldn’t be the hottest year ever recorded.

You win some, you lose some,” Benny Peiser, director of the GWPF, told Reuters, adding that the pace of warming “is not something that people… need to be greatly concerned about”.

Aging Infrastructure, Fracking Eyed in Massive Porter Ranch, California Methane Leak

It's been nearly three months since the Aliso Canyon gas leak in the upscale community of Porter Ranch, CA was first discovered — and, even as that gas continues to spew into the atmosphere, experts are calling attention to the risks that aging fossil fuel infrastructure poses nationwide.

Events of this size are rare, but major leakage across the oil and gas supply chain is not,” Director of Environmental Defense Fund’s California Oil & Gas Program Tim O’Connor said in a statement last month. “There are plenty of mini-Aliso Canyons that add up to a big climate problem — not just in California, but across the country.”
