Pakistan, a country with over a quarter billion people, is one that is extremely vulnerable to climate change. Pakistan, with 25% of its population living in poverty, contributes just 1% of global greenhouse gas emissions. Nevertheless, it experiences increasingly frequent heatwaves, droughts, and catastrophic floods driven by the changing climate.

A subpolar gyre is a large-scale ocean current system located at high latitudes created by a persistent region of low atmospheric pressure. These gyres circulate water in a cyclonic direction – counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. This circular motion of water drives the upwelling of cold, nutrient-rich deep water to the surface, which plays an important role in regulating the climate in the higher latitudes as well as the nutrient cycles that sustain ocean ecosystems. Subpolar gyres influence the circulation of other ocean currents like the North Atlantic Current, the East Greenland Current, and the Labrador Current.

Permafrost is the frozen mix of soil, ice, and rocks that occupies nearly a quarter of the land in the northern hemisphere. It contains vast amounts of animal and plant remains along with bacteria and other microorganisms. All it has been frozen – stuck in time – for millennia.

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.

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.

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.

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.

Ronald K. Brown and Arcell Cabuag, are the founders of Evidence, a dance company that's been open for forty years. Brown tells us “Come see Evidence; you’ll see yourself on stage.” Tune in to hear about dance, Alvin Ailey and the Bedford Stuyvesant Restoration Corporation.

Set and costume designer Santo Loquasto has worked on 80 Broadway shows, 30 films, several operas, and innumerable dance pieces. Here’s something he learned working with Paul Taylor: “Give a man 17 chairs and see what he comes up with.”

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.
