Climate change lawsuits

May 7, 2024 By EarthWise Leave a Comment

For the better part of a decade, there have been lawsuits against fossil fuel companies for their actions related to climate change. The Center for Climate Integrity, a nonprofit that provides legal support to communities suing oil companies, has tracked 32 cases filed by state attorneys general, cities, counties, and tribal nations against companies including Exxon Mobil, BP, and Shell.

There has been extensive news reporting about oil companies’ efforts to undermine the scientific consensus about the climate as well as revelations about oil companies hiding their own research over decades projecting the dangers of climate change.

Oil companies have long sought to shut down the lawsuits or move them from the state courts where they were filed to federal courts where they believe national regulations could override local governments’ claims against them. But a string of circuit court and U.S. Supreme Court decisions have ruled that the cases alleging violations of state laws do belong in state courts.

The first case to reach trial will likely be a Massachusetts case against Exxon Mobil and that could happen as soon as next year.

What do these lawsuits seek? Some seek to force oil companies to pay for the past and future damages caused by climate change that are costing states and communities billions of dollars. Others seek to stop defendants from making false and misleading statements about the effects of burning fossil fuels, from greenwashing their own activities, and to fund corrective education campaigns.

The first trials could lead to a tidal wave of new cases, similar to what happened in the 1990s when tobacco companies were forced to pay billions of dollars under legal settlements.

Airplane Turbulence And Climate Change | Earth Wise

July 4, 2023 By EarthWise Leave a Comment

If you’ve ever been on an airplane, chances are pretty good that you’ve experienced turbulence. As the busy summer travel season kicks off, travelers are being encouraged to brace themselves for a bumpier-than-usual ride.

There has been a major increase in the number of severe turbulence cases on both domestic and international flights. According to a new study by researchers from the University of Reading in the U.K., climate change is leading to this increase in turbulence, driving up costs (via wear and tear on aircrafts), and increasing the risks for passengers and flight attendants. In the United States alone, turbulence costs the airline industry $150-$500 million annually.

The study, which was recently published in the journal Geophysical Research Letters, found that warmer air, caused by carbon emissions, is creating bumpier flights around the world. In fact, the study found that severe turbulence in the North Atlantic is up by 55% since 1979.

The changing climate is affecting air travel in other ways as well. A faster jet stream across the Atlantic is altering travel times. Rising temperatures are reducing the weight that aircraft can carry. Rising seas are threatening low-lying coastal airports around the world.

But carbon emissions from aviation are also a significant driver of the climate crisis. Air travel accounts for approximately 3% of global greenhouse gas emissions, and is one of the fastest growing sources of emissions. According to the International Civil Aviation Organization, emissions from international air travel are expected to triple by 2050.

The future is shaping up to be a bumpy ride.

A Promising Malaria Vaccine | Earth Wise

June 23, 2021 By EarthWise Leave a Comment

Malaria is a parasitic disease transmitted through the bite of female Anopheles mosquitoes. Although the disease is both preventable and treatable, an estimated 435,000 people die of it each year, with the majority being children younger than five. Over 90% of all malaria cases and deaths occur in Africa.

The battle against malaria has mostly centered around the use of bed nets, insecticide spraying and antimalarial drugs. To date, there has not been an effective malaria vaccine available.

That may finally be changing. The first vaccinations have begun in Mali in a phase III trial of a malaria vaccine developed by the University of Oxford. The Oxford vaccine showed an efficacy of 77% over 12 months in a phase IIb trial and the hope is that the phase III trial will lead to the licensing of the vaccine in 2023.

Oxford is partnering with the Serum Institute of India for the manufacturing of the vaccine in order to be able to produce high volumes of low-cost vaccine and provide access to countries where it is required the most. The Serum Institute has committed to the production of more than 200 million doses per year once the vaccine is licensed for use, which will be an adequate supply for children most at risk of malaria in sub-Saharan Africa.

The World Health Organization Malaria Vaccine Technology Roadmap has a goal of a malaria vaccine with at least 75% efficacy. Such a vaccine is needed in order to reach the WHO’s goal of reducing malaria deaths by at least 90% by 2030.
