Fossil fuels

Sixteen young Montanans who sued their state over climate change emerged victorious on Aug. 14, 2023, from a first-of-its-kind climate trial. The case, Held v. State of Montana, was based on allegations that state energy policies violate the young plaintiffs’ constitutional right to “a clean and healthful environment” – a right that has been enshrined in the Montana Constitution since the 1970s. The plaintiffs claimed that state laws promoting fossil fuel extraction and forbidding the consideration of climate impacts during environmental review violate their constitutional environmental right. Judge Kathy Seeley’s ruling in the youths’ favor sets a powerful precedent for the role of “green amendments” in climate litigation. The lawsuit, heard in Montana district court, was the first in the U.S. to rely on a state’s constitutional right to a clean and healthful environment to challenge state policies that fuel climate change...

The world’s largest shipping companies are starting to update their fleets for a greener future. Maersk received the world’s first dual-fuel methanol container ship in July 2023, and dozens more container ships that can run on alternative fuels are currently on order. The industry – responsible for about 3% of global greenhouse gas emissions, more than Canada and Ireland combined – has reasons to act and to have some confidence in its multimillion-dollar investments. On July 7, the 175 member countries of the International Maritime Organization, a United Nations agency that regulates global shipping, agreed to a new climate strategy that includes reaching net-zero greenhouse gas emissions “by or around, i.e., close to, 2050.” The strategy’s language is vague, obscure and almost noncommittal. But it points the industry toward a cleaner future. New European Union rules will also soon go into effect that will significantly raise costs for...

The global climate summit is well into overtime late Tuesday night in Dubai, with no deal on the meeting’s final agreement, and countries are bitterly divided over whether to call time on fossil fuels. Negotiators are scrambling last-ditch meetings to salvage more ambitious language to address the cause of the climate crisis. The latest draft of the COP28 summit’s centerpiece agreement published Monday dropped previous references to phasing out fossil fuels, stoking anger and frustration among some nations and advocates. More than 100 countries support a phase-out of fossil fuels in some form. Instead, the watered-down draft offers a list of actions that countries “could” take to reduce their planet-heating emissions, one of which is reducing the consumption and production of oil, coal and gas. An ambitious deadline set by COP28 President Sultan Al Jaber to strike a deal on a package of agreements expir...

Climate change can seem like an insurmountable challenge. However, if you look closely at its causes, you’ll realize that history is filled with similar health and environmental threats that humanity has overcome. The main cause of climate change – carbon dioxide from the burning of fossil fuels – is really just another pollutant. And countries know how to reduce harmful pollutants. They did it with the pesticide DDT, lead paint and the power plant emissions that were causing acid rain, among many others. In each of those cases, growing public outcry eventually led to policy changes, despite pushback from industry. Once pressured by laws and regulations, industries ramped up production of safer solutions. I am an earth and environmental scientist, and my latest book, “Reclaiming Our Planet,” explores history’s lessons in overcoming seemingly insurmountable hazards. Here are a few examples: Banning DDT despite industry pushback DDT was the f...

Flash droughts develop fast, and when they hit at the wrong time, they can devastate a region’s agriculture. They’re also becoming increasingly common as the planet warms. In a new study published May 25, 2023, we found that the risk of flash droughts, which can develop in the span of a few weeks, is on pace to rise in every major agriculture region around the world in the coming decades. In North America and Europe, cropland that had a 32% annual chance of a flash drought a few years ago could have as much as a 53% annual chance of a flash drought by the final decades of this century. The result would put food production, energy and water supplies under increasing pressure. The cost of damage will also rise. A flash drought in the Dakotas and Montana in 2017 caused US$2.6 billion in agricultural damage in the U.S. alone. Stunted corn in Nebraska struggles to grow during the 2012 flash drought that covered much of the cent...
