A new study published Thursday in the journal Science has determined that if organic carbon in deep layers of soil warms at a rate similar to surface layers it could result in a dramatic increase in carbon dioxide emissions by the end of the century, if not sooner.
According to research by scientists at the Department of Energy’s Lawrence Berkeley National Laboratory, deeper stores of carbon are more sensitive to warming than previously thought.
“Our calculations suggest that by 2100 the warming of deeper soil layers could cause a release of carbon to the atmosphere at a rate that is significantly higher than today, perhaps even as high as 30% of today’s human-caused annual carbon emissions depending on the assumptions on which the estimate is based,” said Caitlin Hicks Pries, a postdoctoral researcher in Berkeley Lab’s Climate and Ecosystem Sciences Division.

The world is getting warmer every year, thanks to climate change — but where exactly most of that heat is going may be a surprise.
As a stunning early spring blooms across the United States, just weeks after scientists declared 2016 the hottest year on record , it’s easy to forget that all the extra warmth in the air accounts for only a fraction of the heat produced by greenhouse gas emissions. In fact, more than 90 percent of it gets stored in the ocean. And now, scientists think they’ve calculated just how much the ocean has warmed in the past few decades.
A new study, out Friday in the journal Science Advances, suggests that since 1960, a staggering 337 zetajoules of energy — that’s 337 followed by 21 zeros — has been added to the ocean in the form of heat. And most of it has occurred since 1980.
“The ocean is the memory of all of the past climate change,” said study co-author Kevin Trenberth , a senior scientist at the National Center for Atmospheric Research.

Carbon dioxide levels measured at NOAA’s Mauna Loa Baseline Atmospheric Observatory rose by 3 parts per million to 405.1 parts per million (ppm) in 2016, an increase that matched the record jump observed in 2015.
The two-year, 6-ppm surge in the greenhouse gas between 2015 and 2017 is unprecedented in the observatory’s 59-year record. And, it was a record fifth consecutive year that carbon dioxide (CO2) rose by 2 ppm or greater, said Pieter Tans, lead scientist of NOAA's Global Greenhouse Gas Reference Network.
<p“The rate of CO2 growth over the last decade is 100 to 200 times faster than what the Earth experienced during the transition from the last Ice Age,” Tans said. “This is a real shock to the atmosphere.”

NEW DELHI: In what could spell bad news for this year's monsoon, international weather agencies have begun predicting an El Nino event in the second half of 2017.
The latest update, from US state agency NOAA and its funded institutions this week, gives a 50-55% chance of an El Nino forming from July onwards. The indication comes on the back of similar computermodel forecasts released by the India Meteorological Department as well as weather agencies of Australia, Europe and Japan over the past month or so.
El Nino is an abnormal warming of the ocean surface in central and eastern equatorial Pacific which alters weather patterns in many parts of the globe. In India, it's usually associated with weak monsoons. The last four El Nino events in 2015, 2009, 2004 and 2002 had led to poor monsoons and drought in the country

Pruitt’s comments produced a torrent of criticism from scientists, environmental groups, and even his predecessor at the EPA, Gina McCarthy.
“The world of science is about empirical evidence, not beliefs,” said McCarthy in a statement. “When it comes to climate change, the evidence is robust and overwhelmingly clear that the cost of inaction is unacceptably high. Preventing the greatest consequences of climate change is imperative to the health and well-being of all of us who call Earth home.”
“I cannot imagine what additional information the Administrator might want from scientists for him to understand that,” McCarthy continued.

In his Letter-to-the-Editor published in the Medicine Hat (Alberta, CA) News, Ed Dick included the following:
Over time, a hypothesis which consistently explains the data becomes a theory. Global warming caused by human activity is a theory which is accepted by an overwhelming majority of climate scientists. A 2016 study led by John Cook investigated 12,000 articles on climate change and, of the just over 4,000 that discussed causation, 97.1 per cent concluded that human activity is a significant causal factor.
John Cook responded to a series of questions about the The Consensus Project in Calan Bentley's Q&A, episode 4 posted on his Mountain Beltway blog hosted on the AGU Blogosphere.
In his New Scientist article, Most people don’t know climate change is entirely human-made, Michael Le Page referenced and linkd to the Advanced version of the SkS rebuttal article, The 97% consensus on global warming.
John Cook spoke with Leia Larsen of the Standard-Examiner about climate change confusion, the current political climate and how to counter alternative facts. Their conversation is documented in Larsen's article, Acclaimed climate science expert to visit Weber State sustainability summit.

Moms Clean Air Force is a community of 1,000,000 moms and dads united against air pollution – including the urgent crisis of our changing climate – to protect our children’s health. We arm members with reliable information and solutions through online resources, articles, action tools, and on-the-ground events. We work across the US on national and local policy issues, through a vibrant network of state-based field teams. Our moms meet with lawmakers at every level of government to build support for commonsense solutions to pollution. Moms have passion and power – an unbeatable combination. We are harnessing the strength of mother love to fight back against polluters.
Moms Clean Air Force is a special project of Environmental Defense Fund.
Are humans contributing only 3% of CO2 in the atmosphere? by Potholer54, YouTube, Nov 30, 2016
Following on Climate Feedback’s analysis of its story titled “Scientists: Here’s What Really Causes Climate Change (And It Has Nothing To Do With Human Beings)”, the Daily Wire has corrected key statements in the brief post—including the headline. Unfortunately, the large number of people who read this widely-shared story are unlikely to see that it has been corrected.
The Daily Wire corrects story analyzed by scientists, but it’s still misleading, Climate Feedback, Mar 7, 2017
