With spring 🌱 upon us in the northern hemisphere, it is the time for the spring bloom in many lakes and oceans. To grow, #phytoplankton require #nutrients and #light, so start reproducing rapidly due to an abundance of nutrients mixed in the water column and increased light intensity 🌞. Zooplankton grazers have yet to increase, and warming conditions help to retain algae near the surface euphotic zone via stratification.

This week's comic: "Protecting the children"

Permanent ice caps have been quite rare in geological history. This new study suggests that's because you need to right combination of paleogeography (which affects weathering rates), exposed lithology (different rocks draw down more/less CO2 as they weather, and plate tectonic configuration (which affects volcanic degassing), all working in the same direction, to get into an icehouse.

That time in 2009 when Donald Trump took out a full-page NYT ad with other business leaders calling on President Obama for aggressive #climate action:
“If we fail to act now, it is scientifically irrefutable that there will be catastrophic & irreversible consequences for humanity & our planet.”

Google and Microsoft recently admitted their emissions are soaring as they build out data centers to power the AI boom.
But new analysis from The Guardian suggests the data center emissions of Google, Meta, Microsoft, and Apple are 662% higher than the companies reporting.

Data center emissions probably 662% higher than big tech claims. Can it keep up the ruse?

Turns out ecologists and entomologists around the world have been warning about declining insect numbers for years. The culprits are climate change, habitat loss, light pollution, intensive farming, pesticide and fertiliser use. But it’s a struggle to get people to act.
It’s not just about bees and butterflies, the poster children of the pollinator world. Other, less photogenic pollinators such as hoverflies, moths, wasps, soldier beetles and earwigs are also showing declines. Several of these species don’t just pollinate. They also eat the pest insects that ruin crops.
Already, in the apple and pear orchards of south-west China, depleted populations of pollinators have forced farmers to hand-pollinate their trees, carrying pots of pollen and paintbrushes with which to individually pollinate every flower. If it sounds labour-intensive and time-consuming, that’s because it is.

“Eat local” is a common recommendation to reduce the carbon footprint of your diet. How does the impact of what you eat compare to where it's come from?Our World in Data
In marine systems where high nutrients lead to #hypoxia (low oxygen), it is commonly thought animals must avoid these zones - wrongly. Many types of #zooplankton seek refuge from predation in low oxygen layers in lakes and oceans. This is quite relevant to the #carbon pump off Peru because mesopelagic zooplankton, including Euphausiid #krill can graze on algae sinking in these zones, and produce rapidly sinking fecal pellets. #Climate

![1. The head of the COP28 climate summit, who is the CEO of an oil company, recently defended fossil fuels.
Al Jaber: "I don't think [you] will be able to help solve the climate problem by pointing fingers or contributing to the polarization and the divide that is already happening in the world."
2. Curiously enough, the fossil fuel tycoon and climate disinformation spreader Charles Koch is funding an institute to study the issue of polarization.
Koch at desk writing a check with framed pictures on the wall reading "Tea Party founding father" and "Heartland Institute".
Koch: America's political divide -- so sad!
3. It seems the concept of "polarization" is a trojan horse for allowing corruption without opposition.
Sign on wall says "Welcome to COP28". Two protesters hold signs reading "PHASE OUT NOW" and "OUR FUTURE IS FOSSIL FREE."
American oil executive: These kids are so angry and uncouth.
Middle eastern oil executive: Truly they are the world's greatest problem.
4. The future is sure to be harmonious.

I know a lot of ppl at #COP28. But the thing is, the majority of them aren’t scientists or legislators. They’re also not working on #ClimateChange issues personally.
I can’t help but wonder if the UN #climate summits have become more of an annual festival than a productive dialogue.
According to The Washington Post, there are a record 84,000 attendees in Dubai this year due to “a large influx of business executives & lobbyists.”

Carbon fuels are death.
in 2013, coal generated 175 times as much electricity as #solar power in the US. Within a decade, in 2022, coal was generating less than 5 times as much electricity (incl. estimated rooftop solar).
So far this year, coal has generated slightly more than twice as much electricity as all solar.
Coal is dying here but needs to die even faster.
