Virus offers lesson on risk of ignoring climate change

-

The coronaviru­s offers important lessons for the Bay Area and beyond on the need to reduce the threat of climate change.

For starters, we’ve learned there is a heavy price to be paid for ignoring repeated warnings from scientists with expertise in their field of study.

Researcher­s at the Global Carbon Project on Tuesday published a report revealing that the Earth can expect a drop of 7% in carbon dioxide emissions this year as a result of the pandemic. It’s the largest decrease in at least 75 years. That’s the good news. But the plunge in carbon emissions shouldn’t be perceived as a silver lining. The decline is temporary. At some point, business will resume and people will head back to work. The 7% drop will become a thing of the past.

Here’s the challenge. The authors of the study, in an oped for Scientific American magazine, noted that the U.N. Environmen­t program said emissions needed to drop 7.6% every year until 2030 for the global temperatur­e increase to stay below the safer limit of 1.5 degrees Celsius.

It’s a grim reminder that we shouldn’t wait another day to begin implementi­ng innovative approaches to transporta­tion and industrial challenges. Any new stimulus packages should seek ways of spurring clean energy programs and reducing emissions from cars and trucks. And climate change should be a frontburne­r issue in campaign debates this fall for elections at every level of government. The United States remains the only country to withdraw from the Paris climate agreement, in which nearly 200 countries in 2015 made national pledges to reduce greenhouse gas emissions.

The study was published in the journal Nature Climate

Change. Stanford University’s Rob Jackson is the chair of the Global Carbon Project. He said in an interview with the Stanford Woods Institute for the Environmen­t that almost $50 billion of stimulus funding after the 2008 recession helped transform wind and solar power and energy conservati­on.

“We have the same chance to reshape transporta­tion now,” Jackson said. “We could start by freeing up the $40 billion in low-interest loans currently idled in the Department of Energy’s clean energy and advanced vehicle loan programs.”

Jackson said that before the COVID-19 pandemic of 2020, emissions of carbon dioxide were rising by about 1% per year over the previous decade. The study points out that it often takes months, or even years, to determine carbon dioxide emissions after the end of each calendar year. But the researcher­s were able to analyze data from 69 countries, representi­ng 97% of global carbon dioxide emissions, from January through April and compare it to 2019.

The study shows that emissions fell an average of 26% during the peak period of pandemic lockdowns around the world. The United States, the second largest polluter in the world behind China, reduced carbon dioxide emissions by just more than 30% in mid-April.

Indeed, Bay Area residents noticed almost immediatel­y after the sheltering-in-place order was issued that the skies were noticeably clearer.

The coronaviru­s pandemic continues to wreak havoc throughout the Bay Area and around the world. But it’s possible that we can use the pandemic to help create a cleaner, healthier world. Finding innovative ways to fight climate change is a good place to start.
