AMOC slowdown: Connecting the dots

AMOC slowdown: Connecting the dots | GarryRogers Biosphere News | Scoop.it
I want to revisit a fascinating study that recently came from (mainly) the Geophysical Fluid Dynamics Lab in Princeton. It looks at the response of the Atlantic Ocean circulation to global warming, in the highest model resolution that I have seen so far. That is in the CM2.6 coupled climate model, with 0.1° x 0.1° degrees ocean resolution, roughly 10km x 10km. Here is a really cool animation. When this model is run with

Global Warming Effects Information, Global Warming Effects Facts, Climate Change Effects - National Geographic

Global Warming Effects Information, Global Warming Effects Facts, Climate Change Effects - National Geographic | GarryRogers Biosphere News | Scoop.it
The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. And the effects of rising temperatures aren’t waiting for some far-flung future. They’re happening right now. Signs are appearing all over, and some of them are surprising. The heat is not only melting glaciers and sea ice, it’s also shifting precipitation patterns and setting animals on the move.

Some impacts from increasing temperatures are already happening.

Arctic Emergency: Top Scientists Explain How Arctic Warming is Wrecking Our Weather and Pushing World To Rapidly Cross Climate Tipping Points

Arctic Emergency: Top Scientists Explain How Arctic Warming is Wrecking Our Weather and Pushing World To Rapidly Cross Climate Tipping Points | GarryRogers Biosphere News | Scoop.it
(Must-watch video that includes direct observation and analysis of Arctic tipping points provided by a number of the world's top climate scientists.) You don't want to mess with Arctic warming. It's an engine of destruction straining to be set loose. A mad burning beast of a thing. One whose fires we are now in the process of stoking to dangerous extremes.

Don’t believe me? Then just listen to top scientists like Dr. Jennifer Francis, Dr. Jason Box, Dr. Jeff Masters, Dr. Natalia Shakhova, Dr. Igor Semiletov, Dr. Peter Wadhams, Dr. James Hansen, Dr. Steve Vavrus, Dr. Ron Prinn, Dr. Kevin Schaefer, Dr. Nikita Zimov, Dr. Jorien Vonk, and a growing list of many, many more (also see above video).

An Arctic that Appears on the Verge of Large Carbon Emissions Adding to an Already Dangerous Human Warming

At issue is the fact that the Arctic is very sensitive to global heat forcing. And any small warming there can rapidly trigger a number of feedbacks that generate more warming for the Arctic and the globe. These feedbacks include but are not limited to:

Global Warming

Global Warming | GarryRogers Biosphere News | Scoop.it
Northern Canada is On Fire, And It's Making Global Warming Worse For the past few weeks, dry and warm weather have fueled large forest fires across Canada's remote Northwest Territories. The extent of those fires is well above average for the year to-date, and is in line with climate trends of more fires burning in the northern reaches of the globe.

Of the 186 wildfires in the Northwest Territories to-date this year, 156 of them are currently burning. That includes the Birch Creek Fire complex, which stretches over 250,000 acres.

The amount of acres burned in the Northwest Territories is six times greater than the 25-year average to-date according to data from the Canadian Interagency Forest Fire Center.

Boreal forests like those in the Northwest Ter..
Garry Rogers's insight:

Increasing fire occurrence means that a site is more likely to be burned a second time before the vegetation can recover.  This quickly leads to a reduction in diversity and stability.

Hot Arctic Water, High Pressure Domes Pushing Sea Ice Toward New Record Lows

Hot Arctic Water, High Pressure Domes Pushing Sea Ice Toward New Record Lows | GarryRogers Biosphere News | Scoop.it

It doesn't take much to shove Arctic sea ice toward new record low values these days. Human caused climate change has made it easy for all kinds of weather systems to bully the ice.


In the case of the past seven days, three moderate strength high pressure cells churned away over the central Arctic, bringing with them clear skies, air temperatures in the range of average for 1979-2000 above the 70 North Latitude line, and a clockwise circulation favoring sea ice compaction and warm water upwelling at the ice edge.

The highs measured in the range of 1020 to 1025 hPa barometric pressure. Moderate-strength weather conditions that during a typical year of the last century would have been almost completely non-noteworthy. Today, instead, we have sea ice extent testing new record lows in the Japanese Space Agency’s monitor.

Garry Rogers's insight:

On the chart, the red line for 2014 intersects the 2011 & 2012 as it reaches July. Will it fall below them as the year progresses?

Canada Is Warming At Double The Global Average

Canada Is Warming At Double The Global Average | GarryRogers Biosphere News | Scoop.it
Canada has been warming at roughly double the global average over the last six decades, setting the stage for dramatic changes to the economy, environment and our very way of life. But government and business have been slow to react and Canada still has no national plan to address climate change.


"As Prime Minister Stephen Harper said recently: "No matter what they say, no country is going to take actions that are going to deliberately destroy jobs and growth in their country. We are just a little more frank about that."


"It's not that we don't seek to deal with climate change, but we seek to deal with it in a way that will protect and enhance our ability to create jobs and growth, not destroy jobs and growth."

Garry Rogers's insight:

Squandering Earth ecosystems for jobs and growth is smash and grab burglary on a grand scale.

Late June 2014: Arctic in Hot Water as Sea Ice Thins and Tundra Fires Erupt

Late June 2014: Arctic in Hot Water as Sea Ice Thins and Tundra Fires Erupt | GarryRogers Biosphere News | Scoop.it

"Atmospheric warming due to human-caused climate change. It's the general measure we've used to track a devastating and ongoing heat amplification due to a terrible greenhouse gas emission. But if we were to look for where the greatest amount of that heat has accumulated, it would be in the world’s oceans. For from its air-contacting surface to its depths thousands of meters below, the World Ocean has captured 93.4% of the total heat forcing humans have already unleashed. The remainder is almost evenly divided between the atmosphere, the continents, and the ice."

I Didn't Care About Climate Change Until I Visited Greenland — Now I'm Freaking Out About It

I Didn't Care About Climate Change Until I Visited Greenland — Now I'm Freaking Out About It | GarryRogers Biosphere News | Scoop.it
I was speechless.  At the end of the Greenland journey, we all wanted to commit to doing something. No one person alone can convince governments to price carbon, or industries to move towards cleaner practices and reduce carbon pollution. The question is: can we do something that has a measurable positive impact? In my case, as an oceanographer and explorer, I will try to help protect as much as the sea as possible from fishing and pollution, so that ocean life can be more resilient against the effects of global warming. I leave it up to you to think about what you are willing to do.
Garry Rogers's insight:

Human impacts are so massive and pervasive that "reasonable" compromises have no effect.  This story is about greenhouse gasses and global warming.  Other stories about plastic in the oceans, pesticides on the land, and our bulging population’s growing need for building, burning, cutting, fishing, grazing, hunting, and plowing are also untouched by "reasonable" compromises.  We need to redefine our compromises to identify effective vs. acceptable solutions.  It is nonsense to let special interests such as the oil/coal industry define reasonable solutions.  After all, corporations can’t vote.

How should "Flathead National Forest 2.0" look? | Conservation

How should "Flathead National Forest 2.0" look? | Conservation | GarryRogers Biosphere News | Scoop.it
Montana's Flathead Forest is one of the most biologically diverse areas of our country, but it needs some work to become more effective for conservation.

"In the northwestern corner of Montana just next to Glacier National Park sits the 2.4 million acre Flathead National Forest. It’s a part of the massive and biodiverse “Crown of the Continent” ecosystem, and is part of a broader collection of protected areas stretching all the way down to Yellowstone. It’s home to more than one thousand native plant species, 70 mammals, and 260 birds. It’s home to iconic American megafauna, like grizzly bears and grey wolves, along with mountain lions, wolverines, lynx, and fishers.

"Starting in the 1930s, concerned citizens and government officials have worked to protect this region, and while it remains mostly unaffected by development, it is starting to suffer the effects of climate change. As glaciers disappear from nearby Glacier National Park, the region will see warmer winters and summers, decreasing snowpack, earlier spring melts, reduced stream flows, and a longer, more severe wildfire season. The animals there will increasingly need more space to roam as their food sources and habitats change with the climate."
