Climate change could alter ocean food chains, leading to far fewer fish in the sea:
As marine ecosystems become increasingly nutrient-starved, phytoplankton growth and net primary production throughout most of the world’s oceans would decline. We estimate that as these impacts ripple up the food chain, global fish catches could be reduced 20 percent by 2300, with decreases of more than 50 percent across the North Atlantic and several other regions. Moreover, at the end of our simulation net transfer of nutrients to the deep ocean was still taking place, which suggests that ecosystem productivity and potential fisheries catch would decline even further beyond 2300.
The courts are deciding who’s to blame for climate change | Dana Nuccitelli:
The case against Exxon and Shell is similar to the case against the tobacco companies – that they engaged in fraud to deceive the American public about the health effects of their products. However, the oil companies modified the tobacco playbook. Rather than directly misinform the public, they funneled money to conservative think tanks who did the dirty work as Merchants of Doubt. By both outsourcing the misinformation campaign and allowing their scientists to publish research in peer-reviewed journals – where it was available to but largely unseen by the public – the oil companies tried to buffer themselves against the legal liability that took down the tobacco industry.
‘Harder and riskier’: Carbon removal needed if Paris goals don’t rise:
“Each tonne of CO2 we don’t emit, we don’t have to remove from the atmosphere afterwards in an expensive and strenuous way,”
Coral reef experiment shows: Acidification from carbon dioxide slows growth:
“Reefs are especially vulnerable to this ocean acidification, because their skeletons are constructed by accreting calcium carbonate, a process called calcification. As the surrounding water becomes more acidic, calcification becomes more difficult.”
Icy Europe, balmy North Pole: the world upside down:
“A Siberian cold front has spread sub-zero temperatures across Europe, carpeting southern cities and palm-lined Mediterranean beaches with snow.On Sunday, meanwhile, air temperatures at the North Pole—which won’t see the Sun until March—rose above freezing.“
It was really cold… < -10 cold.

We spent a month in Antarctica on assignment for @natgeo and it was not until the second week that I realized we had not seen snow once. Every day, however, we experienced several hours of incessant rain. As temperatures warm in Antarctica, the weather regime is changing from snow to rain. In the past, the penguin colony would be covered in snow but now, it is a large, muddy mess. Baby penguins are covered in fluffy down and they can easily preen themselves when it snows. When they get muddy and wet, their down loses its insulation ability and as temperatures drop at night, they become hypothermic and die.
As the debate on weather or not to protect the Antarctic Peninsula starts to play out, I hope that the members of the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR), who will be voting on this issue are inspired to protect it for all humanity.
