In this passionate call to action, 16-year-old climate activist Greta Thunberg explains why, in August 2018, she walked out of school and organized a strike to raise awareness of global warming, protesting outside the Swedish parliament and grabbing the world's attention. "The climate crisis has already been solved. We already have all the facts and solutions," Thunberg says. "All we have to do is to wake up and change."

http://climaterealityproject.org - We know the climate crisis and our dependency on fossil fuel has created a very real threat to public health, but there are individuals, businesses, and entire communities around the globe who are taking action to solve this crisis and create a healthier future for all of us.

For example, back in 1998 the danish government set out to prove that its goal of cutting carbon emissions by 21 percent was not only possible but practical. What happened over the next 20 years is a remarkable story of a community coming together and creating far reaching change.

How do you talk to someone who doesn't believe in climate change? Not by rehashing the same data and facts we've been discussing for years, says climate scientist Katharine Hayhoe. In this inspiring, pragmatic talk, Hayhoe shows how the key to having a real discussion is to connect over shared values like family, community and religion -- and to prompt people to realize that they already care about a changing climate. "We can't give in to despair," she says. "We have to go out and look for the hope we need to inspire us to act -- and that hope begins with a conversation, today."

Most of us know the Arctic exists, but how many have had the chance to see it for ourselves? In our new series Frozen Islands, Arctic Seas, conservation biologist Joshua Powell gives us a glimpse of the remote Russian High Arctic and discusses issues vital to biodiversity in the region. This week, he talks about the threat of plastic waste, which seabirds often mistake for bits of fish. New episodes every Wednesday - subscribe now so you don’t miss out!

You don't have to be a scientist to help protect the world's oceans, says underwater drone expert and TED Fellow David Lang -- in fact, ordinary citizens have pulled together to save the planet's natural treasures many times in history. Lang asks us to take a lesson from the story of the US National Parks Service, offering a three-point plan for conserving underwater wonders.

Peter Kohler, founder of The Plastic Tide project, and Dr. Stefan Leutenegger, Lecturer in Robotics at Imperial College London, discuss how the ocean is under siege from an ever-increasing tide of waste, and how technology like machine learning and drones can help us fix the issue.

Threatening not only a vital economic resource worth an estimated $5 trillion a year but also humanity’s very own life support. The Plastic Tide initiative was started almost two years ago, with the aim of quantifying the problem using drone imagery of UK beaches and beyond: raised awareness and precise data will hopefully drive solutions at societal, political, and technological levels.

They have collected a huge database of drone imagery around UK beaches last year, and a prototype algorithm developed already combines a deep-learning-based plastic detection scheme in the images with geo-referenced mapping. The speakers will show early results and present related research in the space of localization, mapping, and drone flight; and furthermore, sketch the way forward to limit the plastic tide swamping our oceans.

Sunrun co-founder Ed Fenster says, "The best way to talk about climate is just to take an action yourself, then share with your friends how it has made your life better ... believe that the cycle will repeat" #LetsTalkClimate

Plastics are durable, light and versatile. However, they take up to 400 years to decompose. This will affect people’s lives for the next 16 generations.

Our excessive use of plastics is impacting ocean health and biodiversity. By 2050, there could be more plastics in the ocean than fish by weight.

Solomon Hsiang, an associate professor of Public Policy at the University of California Berkeley, explains the correlation of people's health and the temperature.
