Normally when we write, we are writing about big things. 

Getting our atmosphere back into a safe place below 350 ppm is a big task. We are up against a problem of unprecedented scale, the size of our entire planet. In the past two years, we have seen a big response: thousands and thousands of people taking to the streets and organizing in their communities, forming the big movement we need to confront this massive problem. But we also know that it isn't just the big things that are important, its also the little things. 

Last October 10th we saw people all over the world "getting to work" and making small (and sometimes really big) changes. My grandparents, for example, invited two friends over for tea and planted two small shrubs in their garden. Those little bushes won't absorb enough carbon by themselves to get us down to 350ppm, but it's a step – and if we take enough little steps, we can cover a big distance.

Today we are writing to you not about a big thing – but about a very, very small thing.  It so small that you probably won’t ever notice it. Its a tiny tax. Some call it the Robin Hood tax, or the Tobin Tax, or the Financial Transaction Tax. But this little tax isn't made for us "little" people, its taxes a certain type of financial transaction – so its only the folks that make big money in the stock market that would be affected. When we say its little, we mean it. Its tiny: 0.05%. Thats not asking too much from those who have made millions (or billions) by crashing our economy and investing in the companies that are pumping ever more CO2 into the atmosphere.

But what we have learned at 350.org is that little changes, like my grandparents' bushes, can make a big difference. Experts predict that this tiny tax could generate $400,000,000,000 each year! This is a tiny tax with big potential. $400 billion dollars is a lot to be putting every year into our schools and public services that continue to face cuts as bankers get million dollar bonuses. And $400 billion dollars is a lot of money to help the millions of people worldwide who have done nothing to cause climate change but are suffering the most from its impacts. Asking some of the richest people this planet has ever seen to chip in a tiny bit to help fix the problem they helped cause doesn't seem like such a big deal. This financial transaction tax could also help stabalize the market, by limiting the number of high speed trades that have made our modern economy so volatile. Some bankers now just have computers trading for them based on logarithms, making trades every few seconds. This little tax would be enough to stop that irresponsible practice in its tracks. We have big plans for this little tax. And we aren't alone, recently 100 top economists drafted a letter expressing support for it. And numerous European heads of state and more recently the Brazilian senate have publicly supported a financial transaction tax. 

Specific details of international financial policy doesn't often inspire most people. But, I was so excited by the potential and precident of this little tax that I made up a little animation, about it: 

So, now we are going to ask you for a little help in making sure the world knows about this big opportunity to mobilize funding for a fair transition to 350. Can you take the next 0.05% of an hour (approximately 3 seconds) to add your name to the list of supporters for this Financial Transaction tax and to share this video with a few friends? www.350.org/ftt

And…if you can spare a few more seconds, please helps us spread the word to your friends on Facebook & Twitter.

PS: Stay tuned today for hundreds of actions across 35 countries in support of this innovative solution to funding a just transition to a 350ppm world – and find out more, here.
