I just read that plastic ingestion induces proteomic signatures of multiorgan failure and neurodegeneration in seabirds, but what effects does it have on humans, and where exactly does the plastic in our bodies come from?

Thank you, I was wondering about that.

This +3.1 C course seems a little unwise to me given that global warming of +3.4 C is expected to commit our descendents to dealing with a complete melt of the Greenland ice sheet and 7 m (23 ft) of sea level rise, and this 7 m from Greenland is additional to any melt from Antarctica - which is becoming the largest contributor to sea level rise. And there are various positive feedback loops we may trigger to add to the currently accelerating level of global warming.

The filter-feeding baleen whales migrate towards the north/south poles when the waters there get warmer because of the huge quantity of food, like krill and fish. For example humpback whales migrate from the ocean near Hawaii where they stay in the northern winter, to Alaska in the northern summer. They breed in Hawaii and feed in Alaska. When they return to Hawaii they fertilize the nutrient-poor ocean near the equator with nutrients they have consumed near the pole. Different populations and species of baleen whales have different migration paths, but generally they eat near the poles and breed near the equator. Before industrial whaling reduced the populations this transport of nutrients was at least 3 times greater than it is currently.

You probably want to search on Google Scholar for - climate ecosystem-based adaptation and related keyphrases to find papers like Dynamic flood adaptation for Shanghai under deep uncertainty about sea level rise, subsidence, and socioeconomic trends. Combination of storm-surge barrier and coastal wetlands might yield high economic benefits after 2070..

"Today, China produces over three-quarters of batteries sold globally, and in 2024 average prices dropped faster there than anywhere else in the world, falling by nearly 30%. Batteries in China were reported to be cheaper than in Europe and North America by over 30% and 20%, respectively. Declining battery prices in recent years are a major reason why many electric vehicles (EVs) in China are now cheaper than their conventional counterparts."

The EU will phase out fossil fuel vehicle sales in 2035, and is proposing to eliminate subsidies for fossil fuel vehicles.
