Climate change is our new reality
Climate change is no longer a hypothetical threat from some distant future. This summer, it showed up in force.
In Texas, Hurricane Harvey pummeled the Gulf Coast and
inundated Houston, dumping many trillions of gallons of water in rain
and causing so much damage it will take years for the state to recover.
There is no definitive science saying that climate change causes
specific hurricanes. But what we do know is that global warming has
raised sea levels, which strengthens hurricane storm surges. It also
increases precipitation, the real destructor in Texas. That’s because
warmer air holds more water, which falls as rain — in the case of
Harvey, record-breaking rain that has caused perhaps $180 billion in
damage.
Montana, meanwhile, has a different problem. In the past
century, the state has warmed by about 2 degrees Fahrenheit. Heat waves
are more common than they once were, and drought has killed trees, dried
soil and increased the risk of wildfires. The Environmental Protection
Agency estimated in 2016 that the number of above-100-degree days that
Montana experiences each year is likely to double. This summer, drought
and dry weather have created a terrible fire season. At the time of this
writing, 4,000 firefighters, 125 aircraft and 350 National Guard troops
are fighting more than 40 active wildfires in Montana alone. Well over
600,000 acres have already burned there, with no end in sight.
Hurricanes and wildfires are real threats to life and
property. They cost lives and money, and while they cannot be prevented,
they can be prepared for. But doing so requires acknowledging that
these extreme weather events are bound to get worse, and that is
something our current policymakers can’t seem to do. The president
insists that climate change is a “hoax” and won’t allow government
agencies to even mention it.
In this issue, we’re asking a seemingly obvious question:
What if — just what if — climate change is not a hoax? What if there is
no global conspiracy of scientists (or the Chinese) manipulating data to
trick people into reducing the use of fossil fuel? Who in the American
West accepts the reality of climate change and is working to lessen its
impact? We sent writers across the region, from the Pacific Coast to
Alaska, Arizona to Wyoming, to see where and how climate change is
affecting the West, its people and its politics. What we learned is that
though the West is extremely vulnerable to a changing climate, it is
also full of people who are determined to address it. If only that were
true of our national leaders, flying over flood-stricken Texas or
fire-ravaged Montana and wondering why in the heck things seem so out of
control.
