The carbon cycle today is actually acting as a negative feedback, absorbing our fossil fuel CO2.

Then non-linear negative feedbacks occur above some finite amplitude, and produce hysteresis cycles.

When we say «positive» and «negative» feedbacks in the sense of radiation (so I'm not talking about carbon - cycle responses such as methane release from the oceans or such) we're referring to temperature - sensitive variables which themselves affect the radiation budget of the planet.

The why of it is hypothetical but the explanation I came up with is that the hydrologic cycle is a negative feedback.

Corrected the sentence for you — because of course, it is already well known in traditional real world science that the Water Cycle, which you call the «hydrologic cycle», is a negative feedCycle, which you call the «hydrologic cycle», is a negative feedcycle», is a negative feedback.

the explanation I came up with is that because the hydrologic cycle is a negative feedback, where the hydrologic cycle is retarded there is less feedback to dampen warming caused by..

I may be missing something, but I think Willis is describing something like a control system that uses negative feedback to run a step - function or bang - bang heating / cooling cycle.

A continuing negative feedback carbon cycle response, in conjunction with restraint on human emissions, plus some luck with experiencing the lower ranges of climate sensitivity, could lead to climate change of, let's say, 2 °C.

The natural acceleration of the the hydrological cycle that occurs when CO2 levels rise, increases rock weathering and is the key to the negative feedback that eventually pulls the atmospheric CO2 levels back down.

Is there a negative feedback to increasing CO2 (in the water cycle) that will negate its insulating effect?

Truly only one negative feedback in the planet's overall carbon cycle can act with sufficient speed and strength to avert catastrophic climate impacts: The dominant carbon - based life form on this planet will have to respond to the already painfully clear impacts of our carbon emissions by slashing those emissions sharply and eventually running the planet on carbon - negative power.

The carbon cycle has similar negative feedback.

Thirdly, Earth system models have begun to incorporate more realistic and dynamic vegetation components, which quantify positive and negative biotic feedbacks by coupling a dynamic biosphere to atmospheric circulations with a focus on the global carbon cycle (Friedlingstein et al., 2003, 2006; Cox et al., 2004, 2006).

If a shift in the hydrological cycle were to lower the response in the global mean temperature, there may be a poisonous sting in such a negative feedback: changes in the precipitation patterns.

So, that is my basic complaint about the argument that a faster water cycle somehow provides a negative feedback: To the extent that this expected to be true, it is incorporated into the models.

They show that long - term acclimatization or adaptation to warm and acidified conditions could change or even reverse the negative calcification responses observed in short - term studies, and thus alter feedbacks to the global carbon cycle.
