Climate Change

For more than three decades, Bill McKibben has been one of the most influential - and clearest - voices warning about the dangers of a warming planet. In his new book, "Here Comes the Sun: A Last Chance for the Climate and a Fresh Chance for Civilization," McKibben argues that while the window to act is narrowing, it is not yet closed.

Researchers at the King Abdullah University of Science and Technology in Saudi Arabia have found that there are marine bacteria living in all the world’s oceans that are able to consume and digest plastic – in particular polyethylene terephthalate (or PET) plastic – the plastic found in soda bottles, clothing, and many other things.

There has much coverage of the plight of sunflower sea stars, the large starfishes with 16 to 24 arms that inhabit the Pacific Coast of North America. A wasting disease that hit the population starting in 2013 killed off more than 90% of the population from Mexico to Alaska. Only recently has the underlying cause of the disease been identified: a specific bacterium of the Vibrio genus. But sunflower sea stars aren’t the only species that have fallen victim to the wasting disease. In fact, it has killed billions of sea stars in up to 20 species.

Data centers consume large amounts of energy. In 2023, they consumed 4.4% of the nation’s electricity and that percentage is projected to double or triple by 2028, in part due to the proliferation of AI. Much of that power is used to operate computing equipment like servers but nearly half of it is used for cooling systems for the equipment.

Wastewater treatment plants in the U.S. clean trillions of gallons of water each year. Whatever water gets drained down sinks or flushed down toilets goes through these plants to be rendered clean enough to return to the environment.

In the 1990s, the Greenland Ice Sheet as well as the rest of the Arctic region were observed to be measurably thawing as a result of human-caused global warming. At that time, most of Antarctica’s vast ice cap seemed to be securely frozen. Conventional wisdom was that Antarctica’s ice sheets were going to remain stable and were not going to melt much.

Most of us make frequent use of GPS technology to find our way around in our cars. There are increasing numbers of self-driving cars, and they are even more dependent on GPS technology in order to know where they are located. We tend to take for granted that the position shown by the GPS system is correct, but that isn’t always the case.

The world’s largest meat and dairy companies are responsible for emitting more methane than all the countries in the EU and the UK combined. The biggest meat company in the world, the Brazilian company JBS, accounts for nearly a quarter of the industry’s emissions and is more than the methane emissions from ExxonMobil and Shell combined.

The 30th United Nations Climate Change Conference, known as COP30, took place in Belèm, Brazil in November. One hundred ninety three countries plus the European Union registered delegations for the summit. The only countries not officially attending were Afghanistan, Myanmar, San Marino, and the United States.

There are over 3,500 species of mosquitoes. It’s nearly impossible to estimate how many individual mosquitoes there are worldwide. Estimates range from 110 trillion to over a quadrillion. Mosquitoes are found literally everywhere on Earth with only two exceptions: Antarctica and Iceland. Except now they have been sighted in Iceland.
