Living For A Cause is a series of web shorts presented by Greenpeace International Executive Director, Kumi Naidoo.
In episode one Kumi reflects on his first contact with Greenpeace, and the need for greater participation in activism.
Reflecting on 3 years at the helm of what has become a dynamic international organisation, the series presents an 'insider' look at the Greenpeace of today, highlighting some of the more surprising aspects of our organisation, from the well known protest actions, to our people, and volunteers.

David Ritter is CEO of Greenpeace, Australia Pacific, and he talks about the importance of online participation to address Corporate power, particularly their actions involving Coca Cola and Nestle.

When we actually face what's happening on the planet, the picture isn't pretty. Author Carolyn Baker (Speaking Truth To Power) is concerned by rapidly-unfolding climate change, and the fragile Fukushima reactor situation. Systems thinker Dave Pollard (How To Save the World) sees endgames for three inter-related systems--economic, energy and ecology--any one of which could lead to civilizational collapse.
We're in a predicament we can't fix, but we can choose how we respond. Published on Nov 19, 2013

A data visualization of climate change effects. Produced by the International Geosphere-Biosphere Programme and Globaia and funded by the UN Foundation. Published on Nov 19, 2013The data visualization summarises and visualizes several of the most significant statements in the Intergovernmental Panel on Climate Change's (IPCC) recent Fifth Assessment Report, (Working Group I summary for policymakers, the Physical Science Basis). In 2014, IPCC will publish summaries concerning societal impacts, mitigation and adaptation.
The statements and facts presented are derived from the IPCC summary for policymakers.
Jeffrey Sachs presents the key note presentation on sustainability, most particularly sustainable development (environmental and economic) for the first Global Grand Challenges Summit 2013 in London. The lectures is on how sustainable development must occur and how countries are not doing enough to meet this in either terms of energy and the economy. Published on Mar 30, 2013
In an October 15th 2013 article in the Financial Times in response to the climate catastrophe of Typhoon Haiyan, he notes "People need to see credible energy plans, pathways for each country and region to a prosperous low-carbon future. Such pathways can be found, but aside from excellent work in a handful of places, such as the UK, Denmark and California, such long-term planning has not been done...The basic elements of a pathway include four key pillars: more electricity from low-carbon technologies rather than coal; replacing fossil fuels with electricity as the fuel source for sectors such as cars and household heating; greater energy efficiency in industry and the home; and the end of deforestation (which emits carbon).

Have a question that's always confounded you about Earth's climate? Wonder why it matters that the climate is changing now if it has changed before? Or how scientists know changes seen in recent decades are the result of human activities, not natural causes?
Go ahead. Ask a climate scientist.
To submit a question, record a short, 10-15 second video with your question and upload it to YouTube -- and be sure to tag the video "#askclimate" so that we can find it. You can also simply post a question on Twitter with the same hashtag, "#askclimate."
NASA scientists will be recording video responses to some of the questions we receive. The responses will be posted to the NASAExplorer YouTube channel.
Will climate change drastically reduce our food production, or will it change what we produce?
This question from Twitter was posed to Goddard Space Flight Center's Molly Brown as part of NASA's Ask A Climate Scientist campaign, #askclimate

Is there any merit to the studies that show that historical CO2 levels lag behind temperature, and not lead them?
Yes, there's merit to those studies, says Peter Hildebrand, Director of the Earth Science Division at NASA's Goddard Space Flight Center, responding to a question from Twitter (https://twitter.com/Seth_b_clark/stat...).
In the pre-industrial age, the CO2 response to temperature was that the temperature would go up and CO2 would go up. Or if the temperature went down, CO2 would go down. Because when the temperature rose, the whole biosphere revved up and emitted CO2. So we understand that process.
In the post-industrial age, the opposite is true. Increasing CO2 in the atmosphere is leading to increased temperature. So two different things happened, one pre-industrial, where temperature was driving the CO2, and post-industrial, where CO2 was driving temperature. Which means a completely different physical-biological process is going on.Published on Sep 24, 2013

Is there a pause in global warming?
This question was posed to Jet Propulsion Laboratory scientist Josh Willis as part of NASA's Ask A Climate Scientist campaign.
Josh gets asked a lot if there has been a pause in global warming, because temperatures aren't increasing as fast as they were a decade ago. No, he says, global warming is definitely still increasing (http://climate.nasa.gov/key_indicator...). We see more heat being trapped in the oceans, and sea levels are rising. Look at the sea level record for the last decade (http://climate.nasa.gov/key_indicator...). It's going up like gangbusters, hasn't slowed down.
There's not really a pause in global warming. Sometimes there's natural fluctuations and we warm up a little faster in one decade and a little slower in another decade, but global warming, human-caused climate change? Josh says, "that's definitely going right on up in there. We haven't slowed down at all."

In a preview of this week's Moyers & Company, climate communication expert Anthony Leiserowitz explains that single-digit degree changes in our climate are comparable to single-digit degree changes in our body temperature when we get sick. "I think there's an analogy here — that little difference in global average temperature, just like that little difference in body temperature, can have huge implications as you keep going," Leiserowitz tells Bill.
