New study finds the oceans are rising three times faster than they were during the 20th century

GR: Coastal flooding as global warming melts the polar ice caps is one of the most devastating consequences of human-caused climate change. Years ago, scientists predicted that at some point, the rate of sea level rise would accelerate. We have now passed that point. According to NOAA, “nuisance flooding” is already becoming a problem on the U. S. east coast where high tides will be higher than many other places on the globe. Here’s a story on what scientists expect. You will notice that global annual averages are small. However, when you consider totals for decades, and when you consider that the totals will be much higher in some areas like the U. S. east coast, you can see how great the threat is.

“A new scientific analysis finds that the Earth’s oceans are rising nearly three times as rapidly as they were throughout most of the 20th century, one of the strongest indications yet that a much feared trend of not just sea level rise, but its acceleration, is now underway.

“We have a much stronger acceleration in sea level rise than formerly thought,” said Sönke Dangendorf, a researcher with the University of Siegen in Germany who led the study along with scientists at institutions in Spain, France, Norway and the Netherlands.

“Their paper, just out in the Proceedings of the National Academy of Sciences, isn’t the first to find that the rate of rising seas is itself increasing — but it finds a bigger rate of increase than in past studies. The new paper concludes that before 1990, oceans were rising at about 1.1 millimeters per year, or just 0.43 inches per decade. From 1993 through 2012, though, it finds that they rose at 3.1 millimeters per year, or 1.22 inches per decade.

“The cause, said Dangendorf, is that sea level rise throughout much of the 20th century was driven by the melting of land-based glaciers and the expansion of seawater as it warms, but sea level rise in the 21st century has now, on top of that, added in major contributions from the ice sheets of Greenland and Antarctica.

“The sea level rise is now three times as fast as before 1990,” Dangendorf said.

Intelligence community to Trump: When it comes to global warming, you’re wrong

GR: Trump would prefer a few ignorant cheering supporters to a thoughtful response to dangers in the world. Of course, the U. S. oil-money Congress has its own reasons for denying climate change. “. . . the intelligence report also says that biodiversity losses from pollution, overexploitation and other causes is “disrupting ecosystems that support life, including humans.”

“Each year the intelligence community puts together a “Worldwide Threat Assessment” report, and it inevitably scares the hell out of Congress and the public by detailing all the dangers facing the U.S. (Hint: there are a lot of them.)

“This year’s report, published Thursday and discussed at a congressional hearing, makes for particularly disquieting reading.

“While it focuses on the increasing danger that North Korea’s nuclear weapons program poses as well as cyberterrorism threats, one environmental concern stands out on the list: climate change.

“According to the new report, delivered to the Senate Intelligence Committee by Dan Coats, the director of national intelligence (DNI), warns that climate change is raising the likelihood of instability and conflict around the world.

“This is surprising given the Trump administration’s open hostility to climate science findings.

“The trend toward a warming climate is forecast to continue in 2017,” the report states, noting that 2016 was the hottest year on record worldwide. Climate scientists have firmly tied this to human-caused emissions of greenhouse gases, though the report does not make that link.

“This warming is projected to fuel more intense and frequent extreme weather events that will be distributed unequally in time and geography. Countries with large populations in coastal areas are particularly vulnerable to tropical weather events and storm surges, especially in Asia and Africa,” the report states.

“The report also cites worsening air pollution in urban areas around the globe, potential water resources conflicts in places like the Middle East. Interestingly, the intelligence report also says that biodiversity losses from pollution, overexploitation and other causes is “disrupting ecosystems that support life, including humans.”

“The rate of species loss worldwide Is estimated at 100 to 1,000 times higher than the natural background extinction rate, according to peer-reviewed scientific literature,” the report states.

“The findings in this report are surprising considering the Trump administration’s hostility to mainstream climate science findings and policies aimed at cutting emissions of greenhouse gases that are warming the planet. Some agencies, such as the Environmental Protection Agency (EPA) and Interior Department, have gone so far as to take down pages devoted to peer-reviewed scientific reports on climate change.

“For example, EPA administrator Scott Pruitt has said he does not believe that carbon dioxide is the main driver of global warming. This view goes against thousands of peer reviewed climate studies, as well as findings from his own agency.” –Andrew Freedman (Continue reading: Intelligence community to Trump: When it comes to global warming, you’re wrong–Mashable.)

An Armada of Icebergs Has Just Invaded The North Atlantic

GR: Swarms of icebergs are another symptom of global warming that we meet as we cross the threshold of accelerated change. RobertScribbler reports on the complex connections and dangers in many posts. Here’s a sample.

“I have about a decade of experience with the Ice Patrol, and in my time here, and talking with people who have been here longer, I’ve never seen anything like this or heard of anything like this before,” — Gabrielle McGrath, Coast Guard Commander of the US Ice Patrol.

“A Heinrich event is a phenomenon in which large armadas of icebergs break off from glaciers and traverse the North Atlantic.” — Commons

“Consider the situation during past ice sheet disintegrations. In melt-water pulse 1A, about 14,000 years ago, sea level rose about 20 meters in approximately 400 years (Kienast et al., 2003). That is an average of 1 meter of sea level rise every 20 years.” — Dr. James Hansen.

“This week an unprecedented 481 icebergs swarmed into the shipping lanes of a storm-tossed North Atlantic. Strong hurricane force winds had ripped these bergs from their sea ice moored haven of Baffin Bay and thrust them into the ocean waters off Newfoundland. The week before, there were only 37 such icebergs in the Atlantic’s far northern waters. And the new number this week is nearly 6 times the annual average for this time of year at 83. To be very clear, there is no record, at present, of such a large surge of icebergs entering these waters in so short a period at any time in the modern reckoning.

(Many glaciers along the periphery of Greenland have passed the point of no return. In other words, at present temperatures, these glaciers will completely melt. In the past, such major melting events have released ‘armadas of icebergs’ into the North Atlantic in instances called Heinrich Events. Video source: Chasing Ice.)

This week, a massive swarm of icebergs that calved from Greenland and entered Baffin Bay have been kicked into the North Atlantic by a powerful storm system. To be clear, this is the kind of thing you’d expect at the start of a Heinrich Event. Image source: U.S. Coastguard.

Help Save the World

Block Trump. Declare World War on Global Warming and Other Human Impacts on Nature

Our Problem

desert-earth

Earth could join Mars as a dry, lifeless derelict.

Scientists report that growth and spread of humanity together with rising global temperature are causing declining biodiversity, rising seas, growing storms, intensifying drought, spreading disease, and much more. The reports, made by observers all over the world, are like the thunder ahead of a storm that threatens the safety of our families, our friends, our civilization, and all life on our planet. We know it’s coming. Without a massive effort by the people of the world, the storm will grow until terrible destruction ruins our planet. We and all other life may be lost.

Donald Trump’s pre-inauguration statements and cabinet choices make it clear that he will add to global warming and every other negative human impact on Earth.

The Earth continues turning, but if we don’t exert some self-discipline there might one day be no minds that know or eyes that see.

 

Global warming and human population growth are the destructors. They are greater even than fear, hate, and desire;

Together, they threaten humanity and all life on Earth.

Polls show that sixty-four percent of Americans believe global warming is occurring. The number is growing. When the first distant rumbles occurred, we said, “Ah, it might help if we quit burning so much coal, oil, and gas.” Later we said, “Hmm, maybe we need to quit clearing so much land for cities and farms.” And as the danger loomed, we added to the list of things we should do. But we haven’t done much, and the danger has arrived. We are even beginning to realize that the coming storm might be self-sustaining. Global warming might have passed the point at which we can stop it. Seas and soils are warming and releasing their stores of carbon, and the great glaciers are melting and exposing open water. Warming might continue even if we halt all burning and building.

Why War?

Global Warming is at the brink and looking down the slip face of runaway self-sustaining increase beyond our control. The research shows that global warming is already rotting organic matter stored in the tundra and on the ocean floor. Global warming is increasing evaporation and humidity. Global warming is causing soil microbes to release carbon. Methane (CH4), water vapor (H2O), and soil carbon (C in various forms) are joining carbon dioxide (CO2) from burning and are all working together to trap more of the incoming solar energy. The buildup of these gases appears to have taken us past the point at which we can prevent the great storms, droughts, and rising seas. By adding CH4 and H2O to CO2, we are unleashing an exponential spiral that will end human civilization in decades, not centuries. And not far beyond that, end all life on Earth.

overpopulationEven if there was no greenhouse gas and global warming, the spreading human population will eventually wipe out most life on Earth. Already, more than half of all animals are gone, replaced by humans. Family planning, like cutting greenhouse gas, has become an emergency requirement for sustaining life on Earth.

I can’t quite bring myself to believe that our civilization will end within decades. I still believe that we could stop global warming if we make a total effort.

Saving the Earth–The Citizens’ Call Campaign

The Citizens

Sixty-four percent of U.S. adults say they are worried a “great deal” or “fair amount” about global warming. The U. S. adult population totals 242+ million (over age 18). Sixty-four percent equals 154+ million.

The Actions

For those with concern for the future of society and their children, I find it intolerable to say that we must wait and see what happens. Instead, I have a proposal for action:

Leadership in the U. S. and most other nations is not responding to the growing human impact and the global warming threat. I propose that we declare a citizens’ war on the behaviors causing the impacts and threats. We can begin by forcing our elected leaders and our business leaders to organize and lead the war on warming and population growth. We need their help to convert the world’s industries, economies, and societies to the needed total effort to save Earth and us.

Other thinkers are saying the same thing. Here’s Michael Moore’s action plan:

And here is a list of more actions we can take.

Our local action group is forming now and will try to make visits to some of our representatives next week.
