The Panama Canal Is Drying Up

Uh oh.

The Panama Canal is in trouble.

In an advisory dated Monday, the Panama Canal Authority said it will cut the number of ships allowed to pass through the waterway on a typical day in half due to a drought afflicting the region. This year has been the area’s second driest since 1950, according to the authority, with no relief forecast for the rest of 2023.

The authority said “unprecedented” levels at an artificial lake feeding into the canal are forcing it to cut the number of ships making the crossing every day from 32 in October to 25 at the beginning of November. The authority will then continue to slash capacity every month, all the way down to 18 ships on February 1. Typically, 36 crossings are allowed per day. When lighter restrictions were first imposed in August, the result was a pileup at the canal, with more than 160 boats waiting to go through, according to the Energy Information Administration.

The canal works by moving ships up and down through a system of locks, which require water from nearby lakes. When there’s less water in the lakes, fewer of the massive ships that navigate the canal can pass through. That causes delays, which drives up the cost of shipping items through the canal.

Around 500 million tons of cargo pass through the canal annually, according to Bloomberg. That’s about 6% of global trade, most of which starts or ends in the United States.

Climatologists have blamed the drought in Panama on El Niño, the weather pattern that begins with warming water in the Pacific Ocean and often causes dry weather in Panama and wetter winters in parts of the United States.

Biden’s $7 Billion Solar Bonanza

The Solar For All program is the final piece of the $27 billion Greenhouse Gas Reduction Fund.

The great promise of solar panels — in addition to their being carbon-free — is the democratization of energy. Anyone can produce their own power, typically for less than the going utility rate. The problem is that those who stand to benefit the most from this opportunity haven’t been able to access it.

That pattern could change, however, with Solar for All, a $7 billion program under the Environmental Protection Agency to support solar in low- to moderate-income communities. On Monday, the Biden administration announced it was awarding the funds to 60 state and local governments, tribes, and national and regional nonprofits, at an average grant size of more than $80 million.

Things are looking down again for New York’s embattled offshore wind industry.

The state is abandoning all three of the offshore wind projects it awarded conditional contracts to last October, after failing to secure final agreements with any of the developers, Politico reported Friday.

Forever Chemical Enforcement Just Got Even Stronger

In addition to regulating PFAS presence in water, the EPA will now target pollution at the source.

Last week, I reported on the Environmental Protection Agency’s monumental new restrictions on “forever chemicals” in Americans’ drinking water. At the time, I stressed that the issue doesn’t end with the water that flows out of our kitchen and bathroom taps — the government also has a responsibility to hold polluters accountable at the source.

On Friday, the EPA did just that, designating perfluorooctanoic acid and perfluorooctanesulfonic acid, a.k.a. PFOA and PFOS, as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act, more commonly known as the Superfund law.
