dr stephanie roe, global climate and energy lead scientist for the world wildlife fund, thank you song me. the problems with climate change are daunting, but there are some solutions. earlier i spoke to drjonathan foley, ceo of project drawdown, a nonprofit organisation with a mission to "help the world stop climate "change as quickly, safely and equitably as possible." jonathan, i want to start with a tweet i read from you just earlier today, in fact. it was one of the more heartening tweets i have seen on late. you wrote: "yes, the climate crisis is terrifying. "but i'm actually excited by what i see "on the solutions front." tell us more about that? thank you for having me. we are living in an interesting time, the world is in a race now, there is a race between a world where things get much, much worse with climate change, and we just heard a lot about what the possibilities to that world might look like. but there is also another world where we get it right, where we stop climate change and we end up building a better world in the process. i am fighting for that world. and i am

dr stephanie roe, lead scientist at the world wildlife fund, spoke with my colleague carl nasman aboutdlife. thank you so much for taking the time to speak with us. i want to start by asking you about this latest ipcc synthesis report, you were one of the lead authors. it is essentially like a report card for our planet. how does what we are seeing now with this record—setting heat wave fit in with the science released in this report back in march? thanks for having me. the ipcc report was released in march of this year. essentially it was a report card on the fact that we are way off track with limiting warming to 1.5 degrees, which was the global targets set in the paris agreement. essentially, what it said was that we are now experiencing 1.1 degrees above preindustrial temperatures. with that level of warming, we are already seeing catastrophic levels of impacts from climate change, including extreme weather events, which we are seeing play out on our television screens and experiencing daily. so i think one of the main findings was that the model have done a good job tracking the

stephanie: rodney lewis, the tribal attorney who fought for the water rights settlement is the late father of the tribe's current governor stephen roehe senior water rights versus -- stephanie: building on his father's legacy means conserving the water, so he takes particular pride in this water recharge station. it allows the tribe to bank water they don't use. it's the only place where you can still see a slice of the gila river on the reservation. >> we have returned part of the flow of the gila river through this area. and it's become a riparian wetlands area that we're just so proud of. we have over 100 species of birds. when we brought the water back, it was almost like the land healed itself. stephanie: with the gila river no longer the main water source on the reservation, the settlement granted the tribe a big chunk of arizona's colorado river allocation. in fact, the tribe of 21,000 members is the largest single entitlement holder on the colorado river in the state. it is a reversal of fortune that few other native american tribes have achieved. the much larger navajo nation is far from settling its water claims. never min
