New York Times on Climate Change

A couple of articles in the NYT on the effects of climate change. First, one on the oceans: "If fossil-fuel emissions continue to rise rapidly, for instance, the maximum amount of fish in the ocean that can be sustainably caught could decrease by as much as a quarter by century’s end. That would have sweeping implications for global food security: Fish and seafood provide about 17 percent of the world’s animal protein, and millions of people worldwide depend on fishing economies for their livelihoods."

Second, one on agriculture and food production more generally: "Meat and dairy, particularly from cows, have an outsize impact, with livestock accounting for around 14.5 percent of the world’s greenhouse gases each year....Consuming less red meat and dairy will typically have the biggest impact for most people in wealthy countries. That doesn’t necessarily mean going vegan. You might just eat less of the foods with the biggest climate footprints, like beef, lamb and cheese....plant-based foods like beans, pulses, grains and soy tend to be the most climate-friendly options of all."

Offshore Wind... cheaper than coal?

That is the screaming headline of this Bloomberg piece, and if true that's really amazing. I guess I need to read up more on how exactly that is supposed to happen: this short piece doesn't have a lot of details....

Update October 7: one of the reasons is economies of scale, and another reason is improvements in technology such that they turn in even really low wind. I know very little about this technology, but I am curious about how it stands up to extreme conditions. I'm sure the engineers have thought of that, but can they really?

Update October 25:  Another recent report has highlighted the vast potential of offshore wind. Unfortunately this doesn't say why costs are dropping so drastically, but they say that as much as $1 trillion could be invested in projects by 2040. That would be... a lot!

The axes tell you that this giant jump isn't that giant, but still....
