Antarctica’s chinstrap penguins (pictured above) are suffering at the hand of climate change.

Scientists on an 11-day Greenpeace expedition to Antarctica’s Elephant Island to count chinstrap penguin nests found that thousands of penguins are missing. One chinstrap penguin colony has decreased by 77% in nearly 50 years.

This was a huge surprise, as up til now, the chinstrap penguin has been the most abundant penguin species in Antarctica. The chinstrap penguin was previously considered a species of “least concern” by the International Union for Conservation of Nature.

Ornithologist Noah Strycker told National Geographic:
Comparing it to the number from 50 years ago, we’ve found a 56% drop in chinstrap penguin nests, which is rather shocking.
National Geographic continues:
Due to its remote location and challenging conditions, the last census of the chinstrap penguins of Elephant Island was taken in 1971, and that survey identified 123,000 nests. Strycker and his team found less than half of that number.
Why is this happening? Food chain disruption.

Climate change has led to reduced sea ice and warmer oceans — it was a record-breaking 68F (20C) on Thursday at Antarctica’s Seymour Island — which has meant less krill, a main penguin diet staple. And in turn, the Gentoo penguin’s numbers are increasing, as it has a varied diet, including fish and squid, and it can survive in a wider range of conditions.

But this isn’t good for penguins as a whole. The Guardian reports:
Most penguin species are suffering from the warming climate. Two years ago, scientists warned 70% of king penguins could either disappear or be forced to find new breeding grounds by the end of the century. An earlier study found 60% of the Adélie penguin habitat in Antarctica could be lost.
Can we save our aquatic flightless friends? Greenpeace UK says yes:
As wildlife struggles, we urgently need new ocean sanctuaries in the Antarctic and across the world. With these in place, animals like these penguins have the space to recover and adapt to our rapidly changing climate, safe from harmful industries.

To state the obvious, pollution doesn’t recognize or respect state boundaries.

According to a new study by MIT researchers published in Nature, half of the pollution deaths in the US occur in states where the pollution didn’t start. It’s the first study to quantify mortality results.

The MIT researchers focused on combustion pollution such as car and truck engines, power plants, and home HVAC systems. Sectors that are subject to less EPA regulation (although that may change, since the EPA may have its budget slashed by one-quarter) have become greater sources of cross-state pollution. Commercial and residential emissions are now twice that of the power generation sector.

The biggest losers were New York, which experienced the largest number of premature deaths — 3,800 in 2018 — from air pollution created outside the state.

The biggest offenders were Wyoming, North Dakota, and West Virginia, which most consistently produced pollution that affected the health of those in other states.

This happens because of air patterns — and it’s also a perfect example of the fact that we’re all in this together.

Pollution doesn’t respect international borders, either. A new report by the Center for Research on Energy and Clean Air and Greenpeace Southeast Asia called “Toxic Air: The Price of Fossil Fuels” found that air pollution generated by burning fossil fuels causes about 4.5 million premature deaths worldwide annually.

Further, the economic and health costs of air pollution from burning fossil fuels totaled $2.9 trillion in 2018. This was calculated in the form of work absences, years of life lost, and premature deaths.

The study is the first of its kind to quantify the global impacts of air pollution caused by burning fossil fuels.

The most premature deaths from fossil fuel-related air pollution in 2018 were in mainland China (1.8 million), India (1 million), and the US (230,000). Those three countries had the highest annual costs: $900 billion in China, $600 billion in the US, and $150 billion in India. Statista breaks it down by annual percentages as a share of GDP in 2018:

Climate change affects our planet and our health — and thanks to fossil fuels, it’s expensive.

A decade-long study of the Amazon rain forest has found that around 20% of the forest, especially in the southeastern section, has become an emitter of greenhouse gases instead of a carbon sink. This is due to deforestation because growing trees absorb carbon, but dead trees emit it.

UN Development launched an interactive climate-change game called Mission 1.5 Degrees on Thursday.

It’s interactive, it’s country-specific, and they’ve managed to make a serious topic both fun and educational. (Hey UN folks, have you been talking to the Sesame Street folks? They were always good at that kind of thing.)
