Tonight we are walking among giants, the huge sequoia groves of california that draw millions of tourists a year. They are also survivors, struggling with Climate Change. The sequoias need tremendous amounts of water every day, and as Jonathan Vigliotti shows us on our eye on earth, thats a big problem in a state plagued by drought. The forest estimates that about 130 Million Trees died in the state of california during this drought. Reporter 130 million . 130 million. Reporter from the lack of water . Yeah. Reporter tree ecologists Anthony Ambrose and wendy baxter have been working throughout that drought, which lasted from late 2010 to earlier this year. Theyve be analyzing the world famous monsters that survived, the giant sequoias, the largest living creatures on water. Weve mea uses up to a thousand gallons of water in a single day. If that water supply diminishes, there is going to be an impact on the trees eventually.

Reporter but i eventually joined the pair in the deceptive safety of the trees canopy. What has your data that youve collected so far, what has the data told you . They arey by shutting down the little tiny pores in their leaves. Those tiny pores are also what allows them to absorb Carbon Dioxide from the atmosphere. Reporter it sounds like theyre shut down for business. Yeah that. Shut down. Reporter and thats troubling for two reasons. The less Carbon Dioxide trees capture and store, the more of the heattrapping gas stays in the atmosphere, fueling global warming. Also, the trees use Carbon Dioxide as food to grow. But climate is changing. So what does that mean for a tree like the sequoia that has very specific needs in order to survive the way that it has for so long . As it gets hotter, snow is going to melt earlier, and there is going to be less water available for these trees. And it may not be a place that they can continue to grow into the future.
