Carbon-pricing may be off the table, but there is agreement to keep pushing after crucial Paris talks in December

By Bob Berwyn

FRISCO — Climate activists are encouraged by some measured progress at recent talks in Germany, but said there’s still a long way to go to meet the ambitious goal of creating a global agreement to limit greenhouse gas emissions and slow the pace of global warming.

One of the most positive signs at the recent Bonn talks is that most countries seem prepared to keep talking after the COP21 conference in Paris — crucial because the Paris talks likely won’t deliver a deal that meets the make-or-break goal of limiting warming to 2 degrees Celsius.

Global warming to drive massive ocean biodiversity shift

Where will fish go as the oceans warm?

Changes will come at unprecedented pace

Staff Report

FRISCO — Ocean biodiversity is set to change at an unprecedented pace, a team of researchers said in a new study after modeling how global warming will affect some 13,000 ocean species.

The findings reinforce a large body of previous research showing that, in general, many fish will move toward toward the poles looking for cooler water. The researchers pointed out that similar redistributions have happened before — but always on a geological timescale spanning millions of years. Continue reading

NASA to take big-picture look at Arctic climate change

Space-based data to help reveal ecosystem changes

Satellites have long been tracking sea ice loss in the Canadian Arctic, and new climate models suggest that glaciers in the region are also declining rapidly. Visit this NASA Earth Observatory page for more information.

Staff Report

FRISCO — With more and more studies showing big climate-change impacts to Arctic and subarctic ecosystems, NASA is launching a research project to try and understand the bigger picture.

Some recent studies have shown how boreal forests are shifting quickly as temperatures in the high latitudes soar faster than than the rest of the planet. Biologists are trying to project how global warming will affect wildlife in the region, while another study projects that the “green-up” of the Arctic will amplify global warming.

NASA’s 10-year Arctic Boreal Vulnerability Experiment (ABoVE) will bring together on-the-ground research in Alaska and northwestern Canada with data collected by NASA airborne instruments, satellites and other agency programs, including SMAP, OCO-2, and upcoming ICESat-2 and NISAR missions.

Doing the climate-change two-step in Alaska

 

If only speeches could stop global warming …

FRISCO — Secretary of State John Kerry probably expressed what many people feel about climate change when he took to the podium at the GLACIER conference in Alaska Monday, describing the helplessness that can take hold when faced with a seemingly insurmountable problem.

“I have struggled for years, as I’m sure many of you have, with how you adequately take an issue of this magnitude, this kind of challenge, and put it in terms that average folks can really grab onto, where it isn’t so intimidating,” Kerry said.

But that can’t be an excuse to do nothing, Kerry continued, describing the Alaska conference as an important stepping stone on the way to critical climate talk in Paris coming up in December.

“Everywhere I travel, leaders and average folks talk to me about the impacts of climate change and what they feel and see is happening to their lives in one particular part of the world or another. And the Arctic is so important for us to visit and understand because the Arctic is in many ways a thermostat … and yet we already see is having a profound impact on the rest of the planet,” he said.

Kerry also referred to concerns about melting permafrost, which could release heat-trapping gases in such great volumes that it could trigger runaway global warming far beyond and scenario currently represented in climate models.

“The bottom line is that climate is not a distant threat for our children and their children to worry about. It is now. It is happening now. And I think anybody running for any high office in any nation in the word should come to Alaska or to any other place where it is happening and inform themselves about this. It is a seismic challenge that is affecting millions of people today,” Kerry said, describing how Alaska is a poster child for those challenges.

“And unless the global community comes together to address this challenge, the dramatic climate impacts that we’re seeing in this part of the world will be a harbinger for every part of the world,” he said.

 

Environment: Conservation activists call on President Obama to create Alaska marine preserves

 That was certainly not the case on June 17, 2013, the date that the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this rare, nearly cloud-free view of the state. The absence of clouds exposed a striking tapestry of water, ice, land, forests, and even wildfires.

‘Fragile and unraveling’ ecosystems need protection

Staff Report

FRISCO — With President Barack Obama highlighting climate change during a visit to Alaska, conservation activists are renewing their call for the designation of Marine National Monuments in Alaskan waters.

Far from being a frigid wasteland, the region’s ocean and coastal ecosystems are among the most productive in the world. But marine mammal, seabird, and fish populations are in decline, including some that have become threatened or endangered species. And threats from climate change overfishing, pollution, increased shipping, and offshore oil drilling. are growing. Continue reading

Climate: Another warning on permafrost ‘tipping point’

Melting permafrost could trigger a massive surge in global greenhouse gas emissions.

‘The real and imminent threat posed by permafrost thawing must be communicated clearly and broadly to the general public and the policy community’

Staff Report

FRISCO — Policy makers should pay more attention to the potential to the potential for greenhouse gas emissions from melting permafrost, a team of researchers warned in a special bulletin, released as President Obama prepares to attend an international conference on the Arctic.

Arctic permafrost – ground that has been frozen for many thousands of years – is thawing, and the results could be disastrous and irreversible, potentially triggering a spiral of global warming far beyond any of the scenarios currently envisioned, a team of scientists with the Woods Hole Research Center wrote in a policy brief.

Climate: Scientists say Arctic ice loss speeding up

Researchers try to pinpoint sea level rise projections

FRISCO — Sea level is set to rise at least three feet during the next few decades, NASA scientists and ice researchers said this week, updating their latest research and findings on how fast the world’s ice sheets and glaciers are melting.

The scientists said they’re still not sure exactly how fast the water will rise, but they’re getting closer to nailing down the timing, thanks to several ongoing research projects, including a five-year effort to measure ice loss around the edge of Greenland.

The goal, of course, is to help coastal communities prepare for the big changes ahead. Agriculture, transportation and other infrastructure like water treatment plants will all be affected by sea level rise. Continue reading
