Demand for electric vehicles is growing and a new report forecasts that one out of every five vehicles sold worldwide this year will be electric. But charging those vehicles and getting the power you need when you want it can be more complicated. Science Correspondent Miles O'Brien found that out for himself on a road trip in California. He reports in conjunction with Nova's "Chasing Carbon Zero." PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders

As technology grows more sophisticated, so does the potential for deception.

New research shows that climate change is causing the Earth's ice sheets to shrink much faster than previously thought -- the annual rate of sea ice loss has more than tripled since the 1990s. In the Arctic, melting ice is raising geopolitical tensions, kickstarting a global race for potentially priceless minerals, oil deposits and shipping routes. Lisa Desjardins reports.

According to scientists, 80 percent of the Earth's living species are unknown to humans. Even as more are identified, more are disappearing -- and sometimes, we don't know what's being lost until it's too late. This Earth Day, we begin our series "Saving Species" with a look at the world of plants. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders

New research shows that the massive ice sheets at the top and bottom of our planet are shrinking much faster than previously thought. The international study compiled satellite measurements over time and depict what one researcher described as a "devastating trajectory." William Brangham discussed the implications of the analysis with Twila Moon of the National Snow and Ice Data Center. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders

Thursday, Elon Musk's SpaceX launched the first test flight of Starship, its 400-foot rocket meant to one day send people to the moon, and eventually, Mars. The most powerful rocket ever built blasted off from its launch base in Texas but exploded roughly four minutes into its flight. Musk says the next launch attempt will be in a few months.

The Biden administration rolled out its most aggressive effort yet to combat climate change with tougher emissions limits for cars and trucks. But several challenges remain, including the cost of electric cars, the batteries and how to charge them on the road. William Brangham reports on the proposed regulations.

The low-lying nation of Bangladesh suffers disproportionately from climate change, despite producing just 0.5 percent of the world's carbon emissions. It's also creating innovative ways to predict and protect against climate-driven disasters, and discovering new ways to build resilience using natural resources. NPR international correspondent Lauren Frayer joins Ali Rogin to discuss. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
