From the New York Times:

“With flights canceled, cruise ships mothballed and vacations largely scrapped, carbon emissions plummeted. Wildlife that usually kept a low profile amid a crush of tourists in vacation hot spots suddenly emerged. And a lack of cruise ships in places like Alaska meant that humpback whales could hear each other’s calls without the din of engines.

“That’s the good news. On the flip side, the disappearance of travellers wreaked its own strange havoc, not only on those who make their living in the tourism industry, but on wildlife itself, especially in developing countries. Many governments pay for conservation and enforcement through fees associated with tourism. As that revenue dried up, budgets were cut, resulting in increased poaching and illegal fishing in some areas. Illicit logging rose too, presenting a double-whammy for the environment. Because trees absorb and store carbon, cutting them down not only hurt wildlife habitats, but contributed to climate change.”

As for air quality:

“The pandemic helped push American emissions below 1990 levels for the first time. Globally, carbon dioxide emissions fell 7 percent, or 2.6 billion metric tons, according to new data from international climate researchers. In terms of output, that is about double the annual emissions of Japan.

“It’s a lot and it’s a little,” said Jason Smerdon, a climate scientist at Columbia University’s Lamont-Doherty Earth Observatory. “Historically, it’s a lot. It’s the largest single reduction percent-wise over the last 100 years. But when you think about the 7 percent in the context of what we need to do to mitigate climate change, it’s a little.”

“In late 2019, the United Nations Environment Program cautioned that global greenhouse gases would need to drop 7.6 percent every year between 2020 and 2030. That would keep the world on its trajectory of meeting the temperature goals set under the Paris Agreement, the 2016 accord signed by nearly 200 nations.

“The 7 percent drop last year is on par with what we would need to do year after year,” Dr. Smerdon said. “Of course we wouldn’t want to do it the same way. A global pandemic and locking ourselves in our apartments is not the way to go about this.”

Sobering.

From an extremely simplistic point of view, there are two converging problems: (1) The richest 10% of the planet is pumping out more than half of the (way way way too high) emissions; and (2) Some of the poorest parts of the planet have increasing populations that require more and more resources just to survive, and ironically these are (sometimes) places with plentiful “resources” left, including forests and land (after burning the forests) which can be “tapped” when other sources of income (e.g., tourism) drop off the cliff.

We’re currently fucked due to both.
