How can global warming of less than 1 degree Celsius drive extreme weather? You might need to look beneath the surface (of the ocean) for the answer.
It's common knowledge that humans share 99% of their DNA with chimpanzees. But is it true?

Stacey Dooley travels the world to uncover the hidden costs of the addiction to fast fashion. She sees for herself how toxic chemicals released by the garment industry pollute waterways that millions of people rely on. She witnesses the former Aral Sea, once one of the largest bodies of fresh water, now reduced almost entirely to dust. These are shocking discoveries likely to make you think twice about whether you really need those new clothes.

Drill down to discover the treasures beneath our feet that power our world. Fossil fuels–coal, oil, and natural gas–powered the industrial revolution and allowed us to build a way of life that many cherish today. Personal cars, planes, lights, hot showers–all of these are gifts from our fossil fuels… but they have a dirty dark side in that they are polluting the planet. What is it about these natural resources that have allowed them to fuel our civilization? What secrets are locked in their molecules? Where did that energy come from, and can we find alternative energy resources that come in a cleaner form? The hunt is on for new treasures that might allow us to power our modern way of life without damaging the environment. Join NOVA as we explore the resources that both power and pollute, from modern-day oil prospecting in California, to a mega-city utility company struggling to keep the lights on during hot summer days, to China where an engineer strives to solve one of the greatest obstacles to the success of solar power. Travel the globe to see how our energy treasures are changing—and if they can keep the lights on.

We live in an age when technological innovation seems to be limitlessly soaring. But for all the satisfying speed with which our gadgets have improved, many of them share a frustrating weakness: the batteries. Though they have improved in last century, batteries remain finicky, bulky, expensive, toxic, and maddeningly short-lived. The quest is on for a “super battery,” and the stakes in this hunt are much higher than the phone in your pocket. With climate change looming, electric cars and renewable energy sources like wind and solar power could hold keys to a greener future...if we can engineer the perfect battery. Join host David Pogue as he explores the hidden world of energy storage, from the power—and danger—of the lithium-ion batteries we use today, to the bold innovations that could one day charge our world.

90 million miles away from us is the power that shapes our world - the sun. We see it shine in the sky above us, but beyond our sight something dramatic is happening - the sun is going into overdrive.
