The United Nations on Wednesday released a major new report on how climate change is affecting the world’s oceans and frozen areas, like glaciers, ice sheets and permafrost. It contains stark warnings on how rising emissions will affect the environments that blanket most of the earth’s surface — and much of Alaska.

University of Alaska Fairbanks professor emeritus Gary Kofinas was one of more than 100 experts from around the world who authored the report, helping lead the chapter focused on polar regions. Kofinas acknowledged that for Alaskans, a lot of what’s in it won’t be a surprise. 

“Much of what’s happening in polar regions, particularly the Arctic, will be something that people experience firsthand in Alaska,” Kofinas said. “For example, thawing permafrost, changes in seasonality that affect the harvesting for subsistence users and harvesters in general, changes in fisheries, those sorts of things.”

“But what might be new to Alaskans is the scale of change,” he said.

Here are just a few of the report’s takeaways for Alaska:

1: “Ice sheets and glaciers worldwide have lost mass.”

2. “Permafrost temperatures have increased to record high levels.”

3. “Between 1979 and 2018, Arctic sea ice extent has very likely decreased for all months of the year.”

4. “Arctic residents, especially Indigenous peoples, have adjusted the timing of activities to respond to changes in seasonality and safety of land, ice, and snow travel conditions.”

5. “Warming-induced changes in the spatial distribution and abundance of some fish and shellfish stocks have had positive and negative impacts on catches, economic benefits, livelihoods and local culture.”

6. “Summertime Arctic ship-based transportation (including tourism) increased over the past two decades concurrent with sea ice reductions.”

7. “Coastal protection through hard measures, such as dikes, seawalls, and surge barriers, is widespread in many coastal cities and deltas.”

8. Scientists have high confidence that things are going to keep changing — the ocean will continue to warm and marine heatwaves will increase in frequency and intensity, glaciers will continue to lose mass, snow cover is expected to continue to decline and sea ice extent in the Arctic is expected to keep shrinking.

But Kofinas said one of the report’s key messages is that while some climate impacts are already unavoidable, people can still make choices that affect how severe those impacts will be.

“Hardships will be experienced. Adaptation will be needed. But the question is, to what extent, and will we be able to keep pace with those changes,” he said.

Alaska is a destination in which responsible hospitality and travel is critically important.

Often considered as recommended destinations for everybody going to Alaska is

Tongass National Forest. The Tongass is the largest national forest within the United States. It acquired it’s name from the Tongass Clan of the Tlingit native people and dates back to 1902 when President Theodore Roosevelt established the Alexander Archipelago Forest Reserve. In 1908 the forest was re-named and expanded and currently the 16.9 million-acre Tongass National Forest runs from the Pacific ocean to the great inland ice fields that edge British Columbia and from the southern tip of Prince of Wales Island to Malaspina Glacier 500 miles to the north. More than 80 percent of Southeast Alaska is in Tongass and with it’s thousands of islands, fjords and bays the national forest has 11,000 miles of shoreline. Tongass’ considerable coastal rain forest consists of towering hemlock, spruce and red and yellow cedar. The undergrowth beneath thebig conifers is composed of young evergreens and shrubs such as devil’s club, blueberry and huckleberry. Moss and ferns cover the ground, and lichens drape many trees and rocks.

Wildlife is plentiful throughout Tongass. Sitka blacktail deer and its 2 key predators, wolf and brown bear, are located here. Black bear are common as well as mountain goats and some moose. Marine mammals observed along the shores consist of Dall and harbor porpoises, seals and humpback, minke and orca whales and a thriving population of sea otters. The waters teem with fish such as halibut and all five species of Pacific salmon. More bald eagles stay in this region than in any other place in the world. While the place to find the world’s main temperate rain forest, practically fifty percent of Tongass is covered by ice, water, wetlands and rock. It’s most recognized ice floe is the Mendenhall Glacier, Alaska’s “Drive-in glacier” because it is merely 13 miles from down-town Juneau along a paved road. A boat trip from Petersburg or Wrangell brings everyone near the face of LeConte Glacier, the southernmost tidewater glacier on the continent. Merely thirty miles north of Yakutat is Hubbard Glacier, the longest tidewater glacier in the world and easily Alaska’s most active. The 76-mile-long glacier has crossed Russell Fjord several times, lately in 2008. The rip tides and currents that flow in front of the 8-mile-wide glacier are so powerful they cause Hubbard to calve almost constantly. The Tongass incorporates nineteen wilderness areas, including the 545-sq-mile Russell Fjord Wilderness, in addition to Admiralty Island National Monument and Misty Fiords National Monument. Glacier Bay National Park and Preserve and the general area around Haines and Skagway aren’t part of the national forest.
