Can we solve global warming? Lessons from how we protected the ozone layer | Sean Davis

The Montreal Protocol proved that the world could come together and take action on climate change. Thirty years after the world's most successful environmental treaty was signed, atmospheric scientist Sean Davis examines the world we avoided when we banned chlorofluorocarbons -- and shares lessons we can carry forward to address the climate crisis in our time.

Climate Change Is Happening. Here's How We Adapt | Alice Bows-Larkin | TED Talks

Imagine the hottest day you've ever experienced. Now imagine it's six, 10 or 12 degrees hotter. According to climate researcher Alice Bows-Larkin, that's the type of future in store for us if we don't significantly cut our greenhouse gas emissions now. She suggests that it's time we do things differently—a whole system change, in fact—and seriously consider trading economic growth for climate stability.

Global warming -- fact or fiction? | David Bromwich | TEDxColumbus

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Can we stop climate change by removing CO2 from the air? | Tim Kruger

Could we cure climate change? Geoengineering researcher Tim Kruger wants to try. He shares one promising possibility: using natural gas to generate electricity in a way that takes carbon dioxide out of the air. Learn more -- both the potential and the risks -- about this controversial field that seeks creative, deliberate and large-scale intervention to stop the already catastrophic consequences of our warming planet.

How to avoid climate change REALLY FAST

This is NOT ANOTHER typical video about climate change. Dare to see it and it'll never be the same for you. Full video in Spanish:

Climate change is a global challenge that has no borders and to combat it requires coordinated work by all countries. Many people do not know what it really amounts to, either due to unreliable sources or deliberate misinformation, which has led to a series of myths about climate change. In this video we tackle the subject from an objective, scientific viewpoint, discussing the causes and consequences of climate change and how it should be tackled.

How empowering women and girls can help stop global warming | Katharine Wilkinson

If we really want to address climate change, we need to make gender equity a reality, says writer and environmentalist Katharine Wilkinson. As part of Project Drawdown, Wilkinson has helped scour humanity's wisdom for solutions to draw down heat-trapping, climate-changing emissions: obvious things like renewable energy and sustainable diets and not so obvious ones, like the education and empowerment of women. In this informative, bold talk, she shares three key ways that equity for women and girls can help stop global warming. Drawing down emissions depends on rising up, Wilkinson says.

Hydrofluorocarbons (HFC) contribute to ozone depletion and global warming

A class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion. According to the model presented in a new NASA study, their impact is such that HFCs will cause a 0.035 percent decrease in ozone by 2050 and contribution to global warming by all HFCs could be as large as 20 percent that of carbon dioxide.

The ozone layer is recovering - Sustainability for all | ACCIONA

Thanks to the measures adopted in the Montreal Protocol, the ozone layer is recovering. According to a report by MIT (Massachusetts Institute of Technology), since the year 2000, the moment at which the ozone concentration fell to its lowest in history, the hole has reduced by four million square kilometres. The scientific community estimates that, if it continues this rate of recovery, in 2050 the hole will have completely closed, i.e. the concentration of ozone gas will have returned to be the same over the South Pole as before human action provoked its change #OzoneLayer #SouthPole
