Climate change is also increasing “extreme precipitation events” across the state. Alaska's Climate Change Strategy: Addressing Impacts in Alaska. Communities such as As another example of sea ice failure impacting local communities, crabbing season in places like Nome on the Bering Sea coast in Alaska’s northwest has already been shortened by about a month on each side.
See our Although last year’s With evidence continuing to mount in our northernmost state, we should consider it something of a warning of what’s to come elsewhere.The most important news stories of the day, curated by Post editors and delivered every morning.The most important news stories of the day, curated by Post editors and delivered every morning.Interpretation of the news based on evidence, including data, as well as anticipating how events might unfold based on past events All of these things are happening more as climate change, which is warming Alaska at twice the global average, also changes Alaska’s rain, snowpack, and glacial melt — and, accordingly, the flow, timing and temperature of its rivers. This year’s warm season has begun on the same foot.In recent weeks, rivers have lost their ice much earlier than normal, while the extent of ice covering the Bering Sea is alarmingly low.From compromised infrastructure and shifts in plant life, changes resulting from recent climate disruption are tangible.That episode was just the beginning of an early melt off on rivers across the state.The Tanana River at Nenana — to the southwest of Fairbanks, in central Alaska — went ice-free on April 14, which was the earliest in its 103-year record by six days.The early disappearance of river ice in indicative of a The reasons for the winter warmth were multifaceted.

The Adaptation Advisory Group (AAG) to the Alaska Climate Change Sub-Cabinet created this adaptation response plan as part of Alaska's overall climate change strategy, which also addresses mitigation and research needs, and includes a special Immediate Action Workgroup report.

An Anchor River gravel bar at low water on September 3, 2019. With recent years featuring unprecedented lack of sea ice, crabbing was brought to a total halt in some spots.While impacts to some of the most prolific fisheries in the world have yet to show themselves strongly, On land, melting permafrost is releasing gasses like carbon dioxide and methane, part of a feedback loop that also includes more dark soils gathering and storing heat rather than a reflective ice and snow pack that bounces warmth back into the atmosphere.There are some things people think of as positives of a warmer world, like more plant-life in regions that were previously barren.

At its root were persistent areas of high pressure over the Yukon and stretching into the Gulf of Alaska. Changing weather and greater swings in extremes are stressing some plants and causing a number of pests to multiply rapidly as well.Insects like hungry moths have flourished, destroying forests and crushing cycles of berry growth in parts of Alaska With the seeming increase in long-lasting high pressure zones across the region, massive wildfire threat continues to grow over time across Alaska and the Arctic more broadly.Thoman sees this as one of the bigger red flags in the state’s future.

All of these things are happening more as climate change, which is warming Alaska at twice the global average, also changes Alaska’s rain, snowpack, and glacial melt — and, accordingly, the flow, timing and temperature of its rivers. This flow also kept storms coming which in turn helped sea ice fall to near record minimums.According to Rick Thoman of the Alaska Center for Climate Assessment and Policy, the most alarming of all the current signs of climate change in Alaska is open water where there should be sea ice.“Decreased ice extent and thinner, more mobile ice impacts the subsistence economies of western and northern Alaska communities by eliminating or reducing activities that use ice as a platform to work from,” Thoman wrote in an email.He also points to the fact that sea ice changes make wintertime coastal storms more damaging because ice acts as a buffer against waves.
However, in places like Alaska it’s increasingly clear there are other side effects. Climate change is also increasing “extreme precipitation events” across the state.
