you do realize that consultants don't work for free, don't you? Do you think that various climate change cheerleaders like Mann don't charge for appearances? Do we need to remind you of all the money that these guys have taken from the government and other funds in order to support their research and lifestyle?
Pot calling the kettle black I''m afraid.
Scientists don't often charge for appearances, but they do have an expense account as part of disseminating science. They are invited to talk because they tell the truth.
"The outrage of the students striking from school over climate change inaction is “certainly justified”, according to Sir David Attenborough, who said older generations had done terrible damage to the planet.
In an interview with the former UN climate chief Christiana Figueres, the broadcaster and naturalist dismissed critics of the widely praised global movement of school strikes as cynics.

It would still be optional for customers, but if all diners at a certain eatery pay it, the haul would be more than enough to make the establishment carbon neutral, Anthony Myint, an organizer of the initiative, told CNN.
The world's oceans soak up about a quarter of the carbon dioxide that humans pump into the air each year -- a powerful brake on the greenhouse effect. In addition to purely physical and chemical processes, a large part of this is taken up by photosynthetic plankton as they incorporate carbon into their bodies. When plankton die, they sink, taking the carbon with them. Some part of this organic rain will end up locked into the deep ocean, insulated from the atmosphere for centuries or more. But what the ocean takes, the ocean also gives back. Before many of the remains get very far, they are consumed by aerobic bacteria. And, just like us, those bacteria respire by taking in oxygen and expelling carbon dioxide. Much of that regenerated CO2 thus ends up back in the air.
A new study suggests that CO2 regeneration may become faster in many regions of the world as the oceans warm with changing climate. This, in turn, may reduce the deep oceans' ability to keep carbon locked up. The study shows that in many cases, bacteria are consuming more plankton at shallower depths than previously believed, and that the conditions under which they do this will spread as water temperatures rise. The study was published this week in the journal Proceedings of the National Academy of Sciences.

The potential for regime shifts and critical transitions in ecological and Earth systems, particularly in a changing climate, has received considerable attention. However, the possibility of interactions between such shifts is poorly understood. Rocha et al. used network analysis to explore whether critical transitions in ecosystems can be coupled with each other, even when far apart (see the Perspective by Scheffer and van Nes).
They report different types of potential cascading effects, including domino effects and hidden feedbacks, that can be prevalent in different systems. Such cascading effects can couple the dynamics of regime shifts in distant places, which suggests that the interactions between transitions should be borne in mind in future forecasts.
Regime shifts are large, abrupt, and persistent critical transitions in the function and structure of ecosystems. Yet, it is unknown how these transitions will interact, whether the occurrence of one will increase the likelihood of another or simply correlate at distant places. We explored two types of cascading effects: Domino effects create one-way dependencies, whereas hidden feedbacks produce two-way interactions. We compare them with the control case of driver sharing, which can induce correlations. Using 30 regime shifts described as networks, we show that 45% of regime shift pairwise combinations present at least one plausible structural interdependence. The likelihood of cascading effects depends on cross-scale interactions but differs for each type. Management of regime shifts should account for potential connections.

...At one plant in Connecticut a reactor was taken offline for nearly two weeks when temperatures in the Long Island Sound surged past 75 degrees....
...Plants in the U.S., meanwhile, have regularly slashed their output by anywhere from 3% to 60%.
Such dynamics could cause output from nuclear plants to fall by as much as 16% in the coming decades, according to a 2012 analysis. Moreover, climate concerns threaten to pierce nuclear’s carefully constructed – and increasingly embattled – narrative that it’s the only reliable source of zero-emissions power. Already, the country’s aging fleet of nuclear plants is facing stiff competition from cheap natural gas and, more recently, falling prices for solar and wind paired with battery storage...
