Obama: Climate Change ‘Could Mean No More Glaciers In Glacier National Park,’ Statue of Liberty

From Breitbart: 

“During Saturday’s Weekly Address, President Obama stated, “the threat of climate change means that protecting our public lands and waters is more important than ever. Rising temperatures could mean no more glaciers in Glacier National Park. No more Joshua Trees in Joshua Tree National Park. Rising seas could destroy vital ecosystems in the Everglades, even threaten Ellis Island and the Statue of Liberty.”

Melting Glaciers Pose Threat Beyond Water Scarcity: Floods

The tropical glaciers of South America are dying from soot and rising temperatures, threatening water supplies to communities that have depended on them for centuries. But experts say that the slow process measured in inches of glacial retreat per year also can lead to a sudden, dramatic tragedy. The melting of glaciers like Peru’s Pastoruri has put cities like Huaraz, located downslope from the glacier about 35 miles (55 kilometers) away, at risk from what scientists call a ‘GLOF’ — Glacial Lake Outburst Flood.”

Yukon has a new lake, thanks to a retreating glacier

“Yukon has lost a river, and now gained a lake, thanks to the retreating Kaskawulsh glacier.

Geologists and hikers first noticed earlier this summer that the Slims River, which for centuries had delivered melt water from the glacier to Kluane Lake, had disappeared — the glacial run-off was now being sent in a different direction. Now, the level of Kluane Lake has dropped enough to turn the remote Cultus Bay, on the east side of the lake, into Cultus Lake. A narrow channel of water that once connected the bay to the larger lake is gone, exposing a wide gravel bar between the two.”

Shrinking Glacier Is Backdrop to Obama’s Message on Climate Change

“President Barack Obama hiked to a shrinking glacier Tuesday, traveling to this icy expanse to deliver a visual message to the country: This is what climate change looks like. Mr. Obama spent the day in the Kenai Mountains, exploring Exit Glacier, which has retreated as the planet has warmed, touring the area by boat and even taping a segment for an outdoor adventure show. The president’s arguments were familiar, but the White House is hoping that a change in scenery will help galvanize support for combating global warming. His visit comes as public consensus in the U.S. is growing that the earth is heating up and that people are responsible.”

Video of Biking Down a Glacier

The new film, “unReal,” produced by Anthill Films & Teton Gravity Research, features intense biking down a glacier.

Visualizing Glacier Melt Impacts

“With record temperatures and minimum flows in most rivers in the Cascade Range during July and August of 2015, a key question was how much did glaciers contribute in basins that are glaciated?  Note the water pouring off the glacier and the lack of snowcover in the first few minutes of the video.”

Second US Presidential Visit to a Glacier

United States President Barack Obama visited a glacier near Seward Tuesday during a trip to Alaska, making him the second American president to make an official visit to a  glacier. On his trip, Obama took the opportunity to discuss the effects of climate change with Alaska Natives, fishermen and residents of the northernmost state.

“We view this as part of a broader and longer-term effort by the president and the administration to speak openly, honestly and frequently about how climate change is already affecting the lives of Americans and the strength and health of our economy, and also what we can do individually and collectively to address it,” Brian Deese, Obama’s climate, conservation and energy adviser said.

The President and his staff hiked to the Exit Glacier, where markers show the glacier’s retreat in recent decades. Climate change has caused the glacier to retreat an estimated 1.25 miles.

Throughout Alaska, Native communities are struggling to adapt to the effects of climate change. Communities that rely on subsistence hunting find that their ability to harvest meat is dramatically declining as sea ice thins. Dozens of communities are forced to consider relocating as sea level rise  and increased storm surge threaten their towns, a move which would cost millions of dollars.

In many ways, Obama’s visit to the Exit Glacier is a marked contrast from the visit that brought President Warren G. Harding to Alaska in 1923. During Harding’s visit, 5-inch shells were shot into the Taku Glacier to trigger glacial calving. But there are some parallels. Both presidents promoted an extension of transportation into new areas.  Harding pounded the golden spike that completed the Alaska Railroad that linked Seward and Anchorage on the coast with Fairbanks and other towns in the interior. Obama proposed an expansion of the US Coast Guard’s fleet of icebreakers, to help the US keep up with other countries, such as Russia and China, which are increasing their presence in the Arctic Ocean.

Petroleum issues may be the strongest connection between the two visits. Harding’s visit came a year after one of the best-known events in his administration, the Teapot Dome Scandal, in which private oil companies were granted very favorable leases to drill on government lands in the West. The secrecy of the leases caused a public uproar, as did the allegations of bribery. Obama’s visit comes at a time when issues of drilling are once again attracting considerable attention, this time in the Arctic Ocean, and when concern has been expressed over the influence of campaign contributions by energy companies.

Presidents and prime ministers from other countries have also visited glaciers on official trips. Anote Tong, president of Kiribati traveled to a glacier in Norway ahead of Ban Ki-moon’s climate summit in New York in September 2014. The island-nation is rapidly disappearing under water as sea levels rise.

Other presidents have visited glaciers for reasons not related to climate change. India’s Prime Minister Narendra Modi visited the Siachen Glacier, the site of an old battlefield in disputed territory between India and Pakistan.

In 2013, Chile’s President Sebastián Piñera Echenique visited the Union Glacier in Antarctica. There, Echenique expressed his interest in contributing to scientific development and tourism on the southernmost continent.

Obama’s recent visit to Alaska came with a strong message about climate change.

“We are not moving fast enough. None of the nations represented here are moving fast enough,” he said at the GLACIER conference in Anchorage, Alaska, on Monday. “The time to heed the critics and the cynics and the deniers is past. It’s not enough to just have conferences. It’s not enough to just talk the talk. We’ve got to walk the walk.”
