Climate Change Is Literally Making You Lose Sleep

Climate change caused by human emissions of greenhouse gases is wreaking havoc on our planet — from heat waves to heavy rainstorms to higher sea levels, the consequences of global warming are far-reaching. The mere thought of the irreversible damage being done to our planet is enough to leave us tossing and turning at night. But as it turns out, there’s a scientific reason that climate change is literally making us lose sleep.Many of us have had the experience of struggling to fall and stay asleep during a heat wave — especially if we don’t have air conditioning. A newly published paper in the journal Science Advances predicts that as global temperatures continue to rise an increasing number of people will lose sleep.This side effect of climate change will disproportionately affect certain demographics — specifically, people who can’t afford to run their air conditioning all night, and the elderly, who have a harder time regulating their body temperature.According to the researchers’ calculations, an extra six nights of sleeplessness can be expected every month for every 100 Americans by 2050. That number will surge to 14 nights per month by 2099 if global emissions continue at their current level. Sleep deprivation is miserable, but it’s more than a mere inconvenience.Sleep deprivation is miserable, but it’s more than a mere inconvenience […]

Tech CEOs To Trump: We’ll Always Have Paris

It wasn’t quite as romantic as when Ilsa left Rick alone on the tarmac in Casablanca, but the parting of President Trump from the Paris Climate Accord prompted a fast and furious response from America’s major tech companies on Twitter. “Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world,” Tesla and SpaceX founder Elon Musk tweeted. Disney CEO Bob Iger quickly followed: “As a matter of principle, I’ve resigned from the President’s Council over the #ParisAgreement withdrawal.” A more detailed statement followed shortly: “Protecting our planet and driving economic growth are critical to our future, and they aren’t mutually exclusive. I deeply disagree with the decision to withdraw from the Paris Agreement and, as a matter of principle, I’ve resigned from the President’s advisory council.” Salesforce CEO Marc Benioff tweeted “Deeply disappointed by President’s decision to withdraw from ParisAgreement. We will double our efforts to fight climate change.” The tweet was accompanied by the following statement. Microsoft President and Chief Legal Officer Brad Smith wrote on LinkedIn: “Microsoft believes that climate change is an urgent issue that demands global action […]

The Trump Doctrine: Erasing The Black Man’s Legacy

Nikki Haley Says Donald Trump Believes ‘Climate Is Changing’

(WASHINGTON) — Does he or doesn’t he? Believe in climate change, that is. You’d think that would be an easy enough question the day after President Donald Trump announced he was pulling the U.S. out of the landmark global accord aimed at combatting global warming. But don’t bother asking at the White House. “I have not had an opportunity to have that discussion” with the president, responded press secretary Sean Spicer on Friday. “You should ask him that,” offered White House counselor Kellyanne Conway. Environmental Protection Agency chief Scott Pruitt dodged the question, too. The president also ignored it during an unrelated bill-signing. But his U.N. ambassador, Nikki Haley, answered the question in a new way this weekend. “President Trump believes the climate is changing,” she said on CNN’s “State of the Union.” ”And he believes pollutants are part of that equation. So that is the fact.” If so, it’s quite a reversal for Trump, who spent years publicly bashing the idea of global warming as a “hoax” and “total con job” in books, interviews and tweets. He openly challenged the scientific consensus that the climate is changing and man-made carbon emissions are largely to blame. “Global warming is an expensive hoax!” he tweeted in 2014. But Trump has been largely silent on the issue since his election last fall. On Thursday, he made scarce mention of it in his lengthy remarks announcing America’s exit from the Paris accord. Instead, he framed his decision as based on economics. Here’s what he’s said before: ___ Trump’s Tweets: The president’s twitter feed once was filled with references to “so-called” global warming being a “total con job” based on “faulty science and manipulated data.” An Associated Press search of his twitter archives revealed at least 90 instances in which he has referred to “global warming” and “climate change” since 2011. In nearly every instance, he expressed skepticism or mockery. “This very expensive GLOBAL WARMING bulls— has got to stop,” he wrote in January 2014, spelling out the vulgarity. Often the president has pointed to cold weather as evidence the climate scientists are wrong. “It’s 46 (really cold) and snowing in New York on Memorial Day — tell the so-called “scientists” that we want global warming right now!” he wrote in May 2013 — one of several instances in which he said that warming would be welcome. “Where the hell is global warming when you need it?” he asked in January 2015. The same message was echoed in the president’s books. In “Great Again: How to Fix Our Crippled America,” Trump made a reference to “the mistaken belief that global climate change is being caused by carbon emissions.” “If you don’t buy that — and I don’t — then what we have is really just an expensive way of making the tree-huggers feel good about themselves,” he wrote. ___ Candidate And Skeptic: “I’m not a believer in man-made global warming,” Trump told conservative radio host Hugh Hewitt in September 2015, after launching his bid for the White House. He bemoaned the fact that the U.S. was investing money and doing things “to solve a problem that I don’t think in any major fashion exists.” “I am not a believer,” he added, “Unless somebody can prove something to me … I am not a believer and we have much bigger problems.” By March 2016, the president appeared to allow that the climate was changing — but continued to doubt humans were to blame. “I think there’s a change in weather. I am not a great believer in man-made climate change. I’m not a great believer,” he told The Washington Post. “There is certainly a change in weather,” he said. Then-campaign manager, Conway explained Trump’s view this way: “He believes that global warming is naturally occurring. That there are shifts naturally occurring.” ___ Evolving President: In an interview with The New York Times in November, after the election, Trump was asked repeatedly whether he intended to leave the Paris accord and appeared to have a new open-mindedness. “I’m looking at it very closely,” Trump told the newspaper. “I have an open mind to it. We’re going to look very carefully.” He went on to say that he thought “there is some connectivity” between human activity and the changing climate, but that, “It depends on how much.” Asked about the comment several days later, Trump’s now-chief of staff Reince Priebus told Fox News that Trump “has his default position, which is that most of it is a bunch of bunk.” “But he’ll have an open mind and listen to people,” he said. Stay tuned. […]

6 Reasons Pulling Out Of The Paris Climate Agreement Was Totally, Definitely The Right Move

Ben & Jerry’s company recently took a position regarding President Trump pulling out of the Paris agreement with this semi-humorous, if it wasn’t so scary post below. Perhaps the businesses that provided financial contributions to specifically to support this anti-environmental effort will find it enlightening. – Ben Sometimes an idea comes along that is 100% awesome. An idea so good that there’s only one thing you can do: Take an admiring step back and say, “Wow, that’s a really good idea.” When we first learned about cookie butter, for instance, we knew that turning it into a series of ice cream flavors was, without a doubt, a can’t-go-wrong idea. (And take it from anybody who’s tried Spectacular Speculoos Cookie Core, it definitely was.) And that’s exactly how we felt when we saw that President Trump decided to pull the US out of the Paris Climate Agreement […]
