Heat waves are deadlier than hurricanes and fires. Maybe they should get names, too


Highlights

  • Washington D.C. based think tank Atlantic Council launched the Extreme Heat Resilience Alliance which aims to develop a worldwide standard for naming and ranking heat waves
  • People who work outdoors, low-income residences without proper air conditioning, people without homes, and people with health conditions are vulnerable to heatwaves
  • Duke University researchers estimated that during the last decade, the Lower 48 states averaged 12,000 heat-related premature deaths per year
  • Major U.S. cities are experiencing three times as many heat waves as they did in the 1960s, with a heatwave season that is 47 days longer 
  • There is a lower perception of risk in the Northern States, among people over the age of 65, and among white men
  • California Insurance Commissioner Ricardo Lara is also helping to create standards for heatwaves:

In policymaking, we have to grab people’s attention…We know that naming heat waves will provide clear levels of that risk, and more adequate warning to protect our most vulnerable Californians.”


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.

‘Teetering at the edge’: Scientists warn of rapid melting of Antarctica’s ‘Doomsday glacier’

by Harry Cockburn, The Independent 


Highlights

  • The Thwaites glacier in Antarctica, which is almost the same size as the United Kingdom, is melting and its collapse would raise sea levels close to 2 feet
  • This glacier is considered to be very important to the health of other neighboring glaciers. Its collapse may result in the melting of more glaciers according to Paul Cutler of America’s National Science Foundation:

“It is a keystone for the other glaciers around it in West Antarctica… If you remove it, other ice will potentially start draining into the ocean too.”

  • Melt from this glacier already accounts for 4% of global sea-level rise
  • Earlier this year scientists discovered the presence of warm water under the glacier
  • The world has seen a doubling of sea-level rise since 1990
  • Though the Antarctic is experiencing warming, temperatures are rising higher in the Arctic where Siberia has experienced a record high of 100 degrees Fahrenheit

The Climate Center’s Rapid Decarbonization Campaign sets a goal that by 2025, California will have enacted the bold, accelerated policies required by science to double emissions reductions, accelerate drawdown, and secure resilient communities by 2030.

Global warming to push billions outside climate range that has sustained society for 6,000 years, study finds

By Andrew Freedman, The Washington Post


Highlights

Humans have been living inside a “climate niche,” thriving in a certain temperature threshold. Evidence shows that as the earth warms every one degree Celsius, billions of people must migrate or adapt to the new climate. 

  • Humans have been living in a particular constrained climate, around an annual temperature of between 51.8 to 59 degrees Fahrenheit,  for the last 6,000 years that according to the study published in Proceedings of the National Academy of Sciences
  • If warming continues to happen on a large scale, then the human climate niche will be disrupted more in the next 50 years than it has during the past 6,000, inciting mass migration, famine, conflict, and other disruptions to 1 to 3 billion people globally 
  • Around 1% of the Earth’s surface experiences mean annual temperatures above 84.2 degrees Fahrenheit, and this surface area will expand as temperatures continue to rise. These regions notably are experiencing more population growth, meaning climate change will impact more and more over time
  • Neil Adger, professor of human geography at the University of Exeter warns that cities will be severely impacted:

“It is likely climatic changes will in effect move large cities and whole countries into temperature niches that present inhabitants would find unimaginable.”


For a safe and healthy future for all, endorse the Climate-Safe California Platform to implement scalable solutions that can reverse the climate crisis.
