2021 has been a year of extreme weather events in Idaho. Among the worst and most unforgettable was an extreme heat wave.

In the Northwest, including British Columbia, a weather pattern known as a heat dome may have caused 1,400 deaths from the excessive warmth.

Aly Bean, climate campaign coordinator with the Idaho Conservation League, said scientists would typically expect an event like this to happen in the region once every thousand years.

"But climate scientists, after looking into the event and doing some modeling," said Bean, "recognized that this type of extreme heat event is 150 times more likely due to climate change."

Bean said there were other extreme events as well, such as a rise in toxic algae blooms. She also noted that extreme weather has effects on economic drivers like salmon, which came back to Idaho in extremely low numbers this year.

Idaho has also been experiencing one of its most severe droughts in history, which has impacted parts of the economy such as agriculture. Bean said the region is supposed to get more precipitation this winter from a weather pattern known as La Niña.

"If we don't get significantly higher snowpack from this La Nina," said Bean, "the drought from last year will continue for multiple years just because of that soil moisture dryness."

Wildfires once again raged in Idaho and across the West this year, too. But Bean said these events may have a silver lining.

"The really poor air quality index for such a sustained period of time and the huge number of wildfires," said Bean, "really brought attention to what we need to do to adapt for and take care of the health of those that are most vulnerable."

Bean said the state needs to decrease its carbon pollution, including through greater electrification of the transportation system. She also noted the need for changes to the agriculture sector, which is the largest emitter of greenhouse gases in Idaho.

"Finding ways that we can work with farmers and ranchers and dairies to decrease methane emissions is really huge," said Bean. "Also finding ways within the agricultural sector that we can sequester carbon and remove it from the atmosphere will be helpful."

The feasibility of putting solar panels over the state's network of canals is the topic of a big new research project, co-led by the University of Southern California.

The California Solar Canal Initiative builds on a study from the University of California-Merced, which found solar arrays over the canals could generate clean energy, conserve water, reduce air pollution and save land.

Monica Dean, director of climate and sustainability practice at the University of Southern California-Dornsife, said the research will answer practical questions.

"How would we do it? Which canals make the most sense? How much energy could they actually produce? What would the economic implications of doing this be?" Dean outlined. "We're taking a hypothetical scenario and making it real."

The research phase will last about two years and is expected to provide a roadmap for policymakers, utilities and communities. The original Merced study estimated covering the Golden State's canals with solar panels could generate enough electricity to power about 2 million homes each year.

Covered canals also prevent evaporation and could save enough water to meet the residential needs of up to 2 million people per year and they could lower maintenance costs, since fewer weeds grow in shade.

Dean estimated the arrays could save about 50,000 acres of land.

"Rather than needing to put a solar panel on land that could be used for housing or farming or some other purpose, now you're just repurposing existing infrastructure and making it work a little bit harder," Dean emphasized.

The initiative is cosponsored by the independent advisory firm Solar AquaGrid. It will also include faculty from the University of California-Berkeley, the University of California-Irvine, the University of California-Merced and the University of California College of the Law-San Francisco, plus San Jose State University and the University of Kansas.

Insurance rates are rising quickly in California because of fires and floods linked to climate change and now, two new bills in Sacramento seek to make oil and gas companies pay.

The Affordable Insurance and Climate Recovery Act would create legal pathways for homeowners, insurance companies and the state insurance plan to sue and recover losses from oil and gas companies.

Melissa Romero, policy advocacy director for the nonprofit California Environmental Voters, said the companies misled lawmakers and the public.

"The one group that hasn't paid their fair share in all of this is oil and gas companies," Romero contended. "They knew since the '70s and the '80s that their products were creating runaway climate change. They hid the science, they did nothing about it, and they continued to push an agenda that stymied a lot of efforts to switch over to clean energy."

The Western States Petroleum Association called the bills a way for politicians to capitalize on tragedy. The California Independent Petroleum Association said the real culprits for the fires are arsonists, environmental lawsuits that prevent forest management, and cuts to firefighting budgets.

Romero also supports the Polluters Pay Superfund bill, which would charge fossil fuel companies according to their role in climate change and invest in climate-resilient communities.

"It requires the California Environmental Protection Agency to do a report about the actual costs, both looking backwards and forwards, that climate change has caused to California in terms of our infrastructure, disaster response and things like that," Romero outlined.

Proponents of the bills complained insurance ratepayers and taxpayers are hard hit by climate disasters. The state's FAIR Plan, the insurer of last resort, has assessed insurers and ratepayers $1 billion for Los Angeles wildfire claims so far. Meanwhile, State Farm is likely to get regulators' permission to raise homeowners' insurance rates by 22% after a hearing on April 8.

In the face of the severe effects of climate change across the country, new research offers a framework for how to measure Washington's climate resilience.

The research supports Washington's Climate Resilience Strategy, which was published last year.

Carlie Stowe, climate resilience specialist for the Climate Impacts Group at the University of Washington and the paper's lead author, said building resilience is critical in order to minimize effects from droughts, fires and other extreme weather events.

"As the government is investing in resilience, we want to make sure that we're spending that money wisely," Stowe urged. "And that the programs and activities we're investing in are resulting in increased resilience."

Stowe pointed out the research compares Washington's and South Carolina's approaches to climate preparedness to serve as a guide for other states. She added the research is one way to demonstrate Washington's leadership in this area, as taking such measurements is a new practice at the state level.

Stowe noted measuring climate resilience means incorporating data from dozens of sources, across communities, infrastructure, land and governance. It includes air quality levels, damage to infrastructure, and evacuations in extreme events like floods or wildfires.

She emphasized it was helpful to partner with South Carolina on this research, even though each state ended up with a different measurement framework.

"There's a lot more that we can learn together," Stowe stressed. "Continuing partnerships like this is really important for further building resilience across our country."

Stowe added the Washington State Department of Ecology will be implementing the plans and the public will start seeing initial results of the measurements in September.
