Take Action

"Last Hours is a captivating, extremely compelling appeal meant to awaken politicians and business leaders to take climate change action and stop runaway catastrophic climate change. Few films have managed to capture the sense of urgency as well as Last Hours. In the context of science telling us that emissions need to peak by 2015 and then come down, and with politicians doing little to reflect this urgency, this is a much needed asset for the climate movement."
-- Kumi Naidoo, International Director, Greenpeace International

"Last Hours is an alarming video that captures the state of emergency we face with climate disruption--yet at the same time we must recognize that there is real hope: the clean energy industry is rapidly growing, we are making headway in reducing carbon pollution, and by working together we can turn things around."
-- Michael Brune, Executive Director, Sierra Club

"Carbon pollution from burning fossil fuels is changing our climate and transforming our world. From more destructive and more frequent climate-related extreme weather events and rising sea levels, to climate refugees, crop failure and water scarcity, the consequences are profound. Last Hours expertly explains how we got here, and what will happen if we don't work together to stop it. It is a needed and urgent call to action."
-- Al Gore, Chairman, Climate Reality Project

"This is an important video. We have to deal with our carbon dioxide problem now, so we don't have to deal with the methane bomb down the road."
-- Lester Brown, Founder and President, Earth Policy Institute & Founder, Worldwatch Institute

"The fossil fuel industry has broken lots of human laws over the last century. Now the big laws -- Nature's laws -- are catching up to it. As Last Hours makes clear, humankind must choose to rein in its carbon emissions now, or Nature will rein them in for us."
-- Denis Hayes, Founder, Earth Day Network

"The fossil fuel industry has broken lots of human laws over the last century. Now the big laws -- Nature's laws -- are catching up to it. As Last Hours makes clear, humankind must choose to rein in its carbon emissions now, or Nature will rein them in for us."
-- Denis Hayes, President, Bullitt Foundation & Founder, Earth Day Network

"In the 18th century, Edmund Burke wrote, 'Those who don't know history are destined to repeat it.' Many years later, Last Hours makes clear how much we have to learn from our planet's history to truly understand the potent threat of trapped methane. This film acts as a call to action on climate that we must heed."
-- Maggie Fox, President and CEO, Climate Reality Project

"Last Hours is essential viewing for anyone who cares about preventing the disastrous effects of global warming."
-- Thu Pam, Executive Director, Rachel's Network

Taxing Pollution

Polluting companies do not pay a price for their carbon emissions, but society does. A simple carbon tax could transform the worldwide energy landscape.

The Path Forward

We can no longer wait for others to take the first step. It’s up to us and our governments to make ambitious climate commitments, so that others may follow in our footsteps.

Making a Real Difference

The science shows that global temperatures are rising every year, with a 28-year streak of summer records above the 20th century average. We can reverse this trend and bring the climate back into balance, but not unless we take action to phase-out climate pollution. Let’s lead by example and show others, including our elected leaders, that the time to act is now.

Here are six actions you can take today:


The larger the network of informed climate advocates, the more of an impact we can have — both locally and nationally. That’s where you come in. Share this website on Facebook and Twitter, and email the link below to 5 or more friends. Tell them to watch the ‘Last Hours’ video and sign the Global Call for Climate Action.

As consumers, we have the power to both reward the companies that do good, and penalize the ones that don’t.

One way to help encourage clean energy, a major solution for climate change, is to look for the new WindMade label that identifies companies powered by wind energy. If you have a smartphone you can also download an app to help you find the most climate-friendly products.

The GoodGuide scores over 120,000 commonly used items, and a new app called Buycott allows you to scan product bar codes to learn which companies are funded by climate destroyers.

Lighten Your Carbon Load

We have more power than we think. It’s true governments and corporations need to increase their efforts to reduce climate pollution, but we can lead by example in reducing our own “carbon footprints” at home, at work, and at school.

One of the best (and most fun) carbon games out there is my1010 which allows you to compete with friends to slim down your “Blob Man” by selecting from a list of options for reducing your energy and carbon impact. There are many other great carbon calculators that will allow you to discover your true climate impact and how you can lighten your household’s carbon load.

Pressure your Politicians

Sometimes we forget that we are the ones who vote our politicians into office, and many of our elected officials are not doing their duty in working to protect society from the impacts of climate change.

It’s time to let them know that climate change is a key voting issue. Unless elected officials hear from you, their constituents, they will continue to cave to pressure from special interests that want to prevent legislative progress on climate change. Take 5 minutes to find out how your elected leaders are voting on climate change.

In the U.S. you can look up officials who still deny climate change or get a scorecard on the voting record for your representatives.

Fund the Solutions

People around the world are implementing solutions to climate change, and they need funding.

You can help by contributing to solar projects in the developing world through organizations like Renewable WorldSELFEmpowered by Light, and SunFunder. In the US you can now invest in clean energy projects through the Mosaic platform, earning a return on your investment. If you have a pension,find out how your money is being invested, or talk to your financial advisor about buying climate bonds to help fund the low-carbon economy.

You can also donate to important forest conservation efforts like WWF or support wetlands restoration projects that help protect coastal communities from increasing climate impacts.

Join a Climate Campaign

With over 400 partner organizations working around the world, the TckTckTck network offers campaign opportunities on an array of issues related to climate change – from poverty alleviation and food & water access, to public health, national security and marine & forest conservation.
