Tornadoes Hit Unusually Wide Swaths of U.S., Alarming Climate Scientists
By Julia Conley
As the death toll in Oklahoma rose to six Monday amid an outbreak of nearly 200 tornadoes across the Midwest in recent days — as well as in areas far less accustomed to them — climate scientists said such patterns may carry warnings about the climate crisis and its many implications for extreme weather events.
In Oklahoma, tornadoes touched down in at least two cities, including El Reno and Sapulpa, over the weekend, injuring dozens and leveling a number of homes. The tornado that hit El Reno, a suburb of Oklahoma City, was given an EF3 rating, with wind speeds up to 165 miles per hour. Only about five percent of tornadoes are given an EF3 rating or higher.
The tornadoes hit after much of the state endured severe flooding last week, following powerful storms that overflowed the Arkansas River and damaged about 1,000 homes.
While tornadoes have long been a fixture in the Midwest, meteorologist Eric Holthaus tweeted last week that there is "reason to believe major outbreak days ... are getting worse," while climate scientists are examining links between the storms and the climate crisis.
The science of how climate change is affecting tornadoes is still evolving, but there's reason to believe major outbreak days (like today could be) are getting worse.— Eric Holthaus (@EricHolthaus) May 20, 2019

The so-called "Tornado Alley," which covers parts of Texas and Kansas as well as Oklahoma, appears to be growing, according to a study published in Nature last year — making tornadoes more frequent in states that rarely saw them previously including Arkansas, Mississippi and eastern Missouri.
"What all the studies have shown is that this particular part of the U.S. has been having more tornado activity and more tornado outbreaks than it has had in decades before," Mike Tippett, a mathematician who studies the climate at Columbia University told PBS Newshour earlier this year.
As the Kansas City Star reported on Sunday, scientists believe the warming of the globe — fueled by human activities like fossil fuel extraction — is contributing to higher amounts of water vapor in the atmosphere, causing heavier rainfalls which can spawn tornadoes.
The increase in destructive tornadoes across wider swaths of the country than in previous decades "may be suggestive of climate change effects," Purdue University researcher Ernest Agee told the Star.
And the unusual occurrence of tornadoes in far more densely-populated areas than those that frequently see such weather events has led to concerns that tornadoes will become more deadly and destructive than they've been in the past.
"We get caught up on the climate aspect, but the real issue going forward with tornadoes — and hail storms and hurricanes and insert your favorite natural disaster — is the fact that we have more human exposure," Victor Gensini, lead author of the study that appeared in Nature, told Pacific Standard in March.

At unsettling times like the coronavirus outbreak, it might feel like things are very much out of your control. Most routines have been thrown into disarray and the future, as far as the experts tell us, is far from certain.

Farmworkers, farmers and their organizations around the country have been singing the same tune for years on the urgent need for immigration reform. That harmony turns to discord as soon as you get down to details on how to get it done, what to include and what compromises you are willing to make. Case in point: the Farm Workforce Modernization Act (H.R. 5038), which passed in the House of Representatives on Dec. 11, 2019, by a vote of 260-165. The Senate received the bill the next day and referred it to the Committee on the Judiciary, where it remains. Two hundred and fifty agriculture and labor groups signed on to the United Farm Workers' (UFW) call for support for H.R. 5038. UFW President Arturo Rodriguez rejoiced:

A council representing more than 800,000 doctors across the U.S. signed a letter Friday imploring President Donald Trump to reverse his call for businesses to reopen by April 12, warning that the president's flouting of the guidance of public health experts could jeopardize the health of millions of Americans and throw hospitals into even more chaos as they fight the coronavirus pandemic.

Over six gallons of water are required to produce one gallon of wine. "Irrigation, sprays, and frost protection all [used in winemaking] require a lot of water," explained winemaker and sommelier Keith Wallace, who's also a professor and the founder of the Wine School of Philadelphia, the largest independent wine school in the U.S. And water waste is just the start of the climate-ruining inefficiencies commonplace in the wine industry. Sustainably speaking, climate change could be problematic for your favorite glass of wine.
