11/26 Aggregating anemone, rising greenhouse gases, got squid?

Aggregating anemone [Mary Jo Adams]
Aggregating anemone Anthopleura elegantissima
Anthopleura elegantissima lives in rocky areas from the middle to low intertidal zones, it can also be found higher in tide pools...Colonies of Anthopleura elegantissima may cover large rocks. These cloned individuals usually don't grow more than about an inch across before splitting into two new anemones. Larger solitary individuals can be found in tide pools and in the low intertidal zone. This anemone is generally green with pink or purple tipped tentacles. The exact shade of green varies depending on the presence and ratio of two single-celled symbiotic organisms in its tissues; a green algae and an olive or golden brown dinoflagellate. Without the symbiont, they appear grayish or white except for the pink on their tentacles. (Sound Water Stewards)

Climate change: Greenhouse gas concentrations again break records
Atmospheric concentrations of carbon dioxide and other greenhouse gases once again reached new highs in 2018. The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade. Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts. Since 1990 there's been an increase of 43% in the warming effect on the climate of long lived greenhouse gases. Matt McGrath reports. (BBC) See also: World Powers Vowed to Cut Greenhouse Gases. They’re Still Rising Perilously.  Somini Sengupta reports. (NY Times)

Got squid?
Yesterday's item about catching and eating Puget Sound squid [Got squid? Why officials say you should catch and eat it out of Puget Sound] prompted our Bad Punster Home Runster columnist to write: "I gotta tell you, getting us Northwesterners to switch from eating salmon to cephalopods may require some serious outreach, perhaps even a bit of squid pro quo." Undaunted, she returned with: "I’m kraken myself up over here."
