David Suzuki: Humanity’s Fate Depends on the Choices We Make Today
We're living in a time of records. More renewable energy came on stream in 2015than ever—147 gigawatts, equal to Africa's entire generating capacity—and investment in the sector broke records worldwide. Costs for producing solar and wind power have hit record lows. Portugal obtained all its electricity from renewable sources for four straight days in May—the longest achieved by any country—and Germany was able to meet 90 percent of its electricity needs with renewable power for a brief period. Clean energy employment and job growth now outpace the fossil fuel industry by a wide margin.
That's just a portion of the good news. Oil prices have fallen so low that some more damaging activities are becoming unprofitable, a record number of coal companies are going bankrupt or filing for bankruptcy and fewer coal mines are operating in the U.S.
But are the good records enough to help us deal with the bad? Global average temperatures are hitting record highs every recent month and year and atmospheric concentrations of greenhouse gases are rising steadily, to levels unheard of in human history. Arctic sea ice is vanishing at unprecedented levels, mass bleaching is killing the Great Barrier Reef and record-setting droughts, floods, heat waves and extreme weather are happening around the world.
As Prof. Stefan Rahmstorf of Germany's Potsdam Institute for Climate Impact Research told the Guardian: "These are very worrying signs and I think it shows we are on a crash course with the Paris targets unless we change course very, very fast. I hope people realize that global warming is not something down the road, but it is here now and is affecting us now."
The Paris agreement, accepted in December by most nations, offered hope that world leaders are aware of this serious problem and know that unless we quickly employ a range of solutions—from renewable energy to reducing consumption to changing dietary and agricultural practices—humanity is at risk.
Despite overwhelming evidence for human-caused climate change, the fossil fuel industry continues to employ shady people and organizations to fool fearful and apparently blind followers into believing the problem doesn't exist or isn't serious enough to worry about. Their messaging follows a pattern: Spread a simplistic lie until it becomes so discredited that few people accept it and then move on to another simplistic lie.
The most recent from Canadian industry propagandists like Patrick Moore, Tom Harris (of the misnamed International Climate Science Coalition) and their pals at organizations like the U.S. Heartland Institute is that CO2 is not a pollutant, just a benign or beneficial gas that stimulates plant growth. It's true CO2 is good for plants. So is nitrogen, but when it runs into waterways and the oceans, it pollutes them. Overwhelming scientific evidence proves that increased atmospheric CO2 is a major cause of global warming. The profound effects of that warming are already here and new and frightening aspects are also coming to light, such as ocean oxygen depletion.
Recent bankruptcy filings for Peabody Energy showed the U.S. coal company owes money to a range of deniers and their organizations, including the also misnamed Calgary-based Friends of Science. It claims the sun and not human activity drives climate change (and that the world is cooling, not warming), a ridiculous assertion, often repeated by coal companies, that real scientists have thoroughly debunked. Extensive research shows coal, oil and gas interests have pumped huge amounts of money into these denial campaigns, all the while knowing that human-caused climate change is real and dangerous.
It's good that deniers' voices are being drowned out by evidence and rational arguments and that solutions are becoming better, cheaper and more readily available daily. But we no longer have time to allow compromised politicians, greedy industrialists and dishonest organizations to stall progress. We need record numbers of people to do all they can—develop solutions, write letters, sign petitions, talk to politicians, vote and take to the streets—to demand that governments, industry and society treat climate change with the seriousness it deserves.
Humanity's fate depends on the choices we make today. We can't let a polluting sunset industry and its minions block progress to a cleaner, healthier future.

A recent intensification in protests against Williams Partners' planned Atlantic Sunrise pipeline in Pennsylvania prompted a state senator to propose legislation aimed at limiting demonstrations.
Last month, Pennsylvania Sen. Scott Martin (R-Norman) announced his intention to introduce legislation that would pass the costs of law enforcement responding to protests onto the demonstrators. Martin also helped introduce a different bill that would criminalize protests at natural gas facilities.
The so-called "first and last mile" problem is one of the biggest hurdles with public transportation. How do you encourage more people to take Earth-friendlier commutes when their homes are miles away from the train or bus station?
One solution, as this Estonian electric scooter company proposes, is to simply take your commute with you—literally. Tallinn-based Stigo has developed a compact e-scooter that folds to the size of a rolling suitcase in about two seconds.
[Editor's note: I'm still in shock after hearing the news that Lucia Grenna passed away in her sleep last week. When we first met in April of 2014 at a Copenhagen hotel, I was immediately taken by here powerful presence. We spent the next couple days participating in a Sustainia climate change event where Lucia presented her audacious plans to connect people to the climate issue. I had the chance to partner with Lucia on several other projects throughout the years and work with her incredible Connect4Climate team. I was always in awe of her ability to "make the impossible possible." Her spirit will live on forever. — Stefanie Spear]
It is with a heavy heart that Connect4Climate announces the passing of its founder and leading light, Lucia Grenna. Lucia passed peacefully in her sleep on June 15, well before her time. We remember her for her leadership and extraordinary ability to motivate people to take on some of the greatest challenges of our time, not least climate change.

Neil deGrasse Tyson has inspired millions of people to care about science and imagine themselves as participants in the scientific process. What a hopeful sign it is to see young girls wearing t-shirts emblazoned with the words, "Forget princess, I want to be an astrophysicist."
As Trevor Noah noted during The Daily Show episode last night (starts at 2:25), the real reason Trump has these rallies is to "get back in front of his loyal crowds and feed of their energy." Noah believes that "Trump supporters are so on board with their dude he can say anything and they'll come along for the ride."

Two years ago—long before coal became one of the most dominant and controversial symbols of the 2016 presidential election—Bloomberg Philanthropies approached production company RadicalMedia with the idea of creating a documentary exploring the U.S. coal mining industry. Last spring, they brought on Emmy-nominated director Michael Bonfiglio, tasked with forging a compelling story out of the multitudes of facts, statistics and narratives underlying the declining industry.
