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.

Hotter and drier conditions driven by climate change are leading to an increasing number of wildfires in North America and around the world. These fires are growing larger and burning longer, spreading into biodiversity-rich regions once considered too wet and humid to sustain them.

The Merrimack Station, located in Bow, New Hampshire, officially ceased operations on September 12th. It was the last coal-fired power plant in New England.

What we eat has a profound impact on the planet. According to a new study led by scientists from the University of Michigan and the University of Minnesota, our dietary choices - and where we make them - strongly influence our contribution to climate change. The study, which was recently published in the journal Nature Climate Change, found meat consumption in the U.S. generates a massive and often overlooked source of greenhouse gas emissions.

The Environmental Protection Agency under the Trump administration has proposed a new rule that would dramatically weaken safety reviews for some of the most toxic chemicals that are already on the market.

On October 2nd, the Trump Administration announced the termination of 321 awards, claiming to achieve $7.5 billion in savings from clean energy projects. In reality, many of these awards were already past their end date and the money had already been spent. However, the cuts still amount to nearly $5 billion.

Anyone who has flown out of cold places in the winter has experienced airplane deicing. The process, which must be performed just before takeoff to ensure safety, involves spraying a heated, glycol-based fluid onto aircraft surfaces to remove existing ice, snow, or frost. These frozen coatings can dangerously reduce lift and control during flight. They are often removed with electrical heating before deicing fluid is applied. The effectiveness of the deicing lasts for only a limited amount of time. If there are delays in takeoff, deicing may need to be repeated. Deicing is expensive and can lead to major delays in air travel during the winter.

Switzerland has over 1,400 glaciers. Some of them are world famous, including the largest one, the Aletsch Glacier, which is a World Heritage Site located in the Barnese Alps. At its deepest point, it is about 3,000 feet thick. But like other glaciers in Switzerland, the Aletsch is shrinking – by more than 150 feet per year due to global warming. In total, more than 1,000 small glaciers have melted away entirely since the 1970s.

The Trump administration decided this year to stop updating a federal database that tracked the cost of extreme weather, compiling an annual list of hurricanes, wildfires, and other disasters that caused at least $1 billion in damage. The government had maintained that database since the 1990s, with data going back to 1980. Evidently, this information was deemed to be unimportant, or at least inconvenient.
