The climate science behind this year’s wildfires and powerful storms

by Scott Pelley, 60 Minutes


Highlights

  • In 1988, NASA scientist James Hansen discovered that man made climate change would lead to a global rise in temperatures by the year 2020
  • “Career fires” or fire events that firefighters would likely only see once in their career, can typically burn up to 50,000 acres and are happening yearly in California
  • Though Hansen predicted climate changes three decades ago, he hoped that governments would have taken action:

“Well, if we don’t change anything, then we’re going to continue to see more and more of these extreme regional events because the physics is quite simple. As you add more greenhouse gases to the atmosphere, you increase the heating of the surface. So, at the times and places where it’s dry you get more extreme droughts. The fire seasons become longer. The fires burn hotter. But at the times and places where it’s wet, you get more evaporation of the water. And you get warmer, moist air, which provides greater rainfall. And it’s the fuel for storms.”

  • Many serious climate change effects such as mega-drought and melting ice sheets are occurring at a faster rate than what scientists previously predicted 
  • Hanson believes the best way to stop climate change would be to reduce all emissions to zero in order to allow the ocean and forests to sequester excess carbon
  • Another method Hanson suggests is taxing fossil fuels in order to make clean alternatives more cost-effective

Scientists are increasingly warning that to avoid catastrophic impacts from climate change, the world’s governments must implement massive reductions of warming emissions and begin a drawdown of greenhouse gases (GHG) from the atmosphere over the decade ahead.  For a safe and healthy future for all, endorse the Climate-Safe California Platform to implement scalable solutions that can reverse the climate crisis.

Cyclone Idai: Estimated 900,000 children orphaned, separated or impacted in Mozambique

by Cara Anna, Global News

Her name is Chuva, which in Portuguese means rain. For four days that was all she saw as she clung to her rooftop in the cyclone’s aftermath and prayed to be saved.

Maria Chuva clasped her 5-year-old daughter, Amiel, to her tightly as she recounted the panic of opening her front door to water that came up to her neck, and scrambling with her family to the roof.

Now, after elbowing her way onto a rescue boat for a bewildering journey with her two girls to the inundated port city of Beira, she paused in the din of a displacement camp to reflect on losing everything but her children — and the splintered families now around her. The orphans are especially hard for her to bear.

“It hurts me so bad,” she said.

An estimated 900,000 children have been orphaned or separated from their families, made homeless or otherwise affected by Cyclone Idai, half of the 1.8 million people impacted overall, according to Mozambican government figures.
