Climate Policy, RBG Songs, Locust Tech

President Biden and other countries have promised to cut greenhouse gas emissions, but what good are these goals since global emissions continue to rise? Then, we hear a special musical tribute to Supreme Court Justice by Ruth Bader Ginsburg. And how an anti-locust operation used technology to help prevent widespread damage by the insects in Africa last year. Also on today's show: why low-income homeowners shoulder more than their fair burden of property tax in many communities, how an endangered Australian bird is losing its song, and how food waste can be turned into fuel for jets.
