Sentences with phrase «feedback cycles like»

The threshold temperatures after which feedback cycles like the one hypothesized by Hansen et al. activate are not well known or studied.

Not exact matches

The entire cycle is a self - regulating feedback mechanism, like the thermostat on a house's heating and cooling system, because the «puddle» of gas around the black hole provides the fuel that powers the jets.

«The entire cycle is a self - regulating feedback mechanism, like the thermostat on a house's heating and cooling system, because the «puddle» of gas around the black hole provides the fuel that powers the jets,» NASA said in the statement.

I do set goals at work and go through a yearly feedback cycle, but I like to take the new year as an opportunity to look at my career from the outside.

I like to systematically cycle through the students to whom I give feedback.

That feedback is then passed through to a TDDI team who discusses and decides which features can be rolled out and what the development cycle will be like for each.

Most of the companies that end up on this list have gone through several economic cycles and kept growing distributions, which is the type of consistently positive feedback dividend income investors like in any market.

It's a difficult job because the feedback cycles are so long — especially when it comes to investing in illiquid assets like startups (and Unicorns).

If the CO2 rise is a carbon cycle feedback, this is still perfectly compatible with its role as a radiative agent and can thus «trigger» the traditional feedbacks that determine sensitivity (like water vapor, lapse rate, etc).

[Response: These feedbacks are indeed modelled because they depend not on the trace greenhouse gas amounts, but on the variation of seasonal incoming solar radiation and effects like snow cover, water vapour amounts, clouds and the diurnal cycle.

«This graph gives you an idea of what the Anthropocene climate looks like as... without even taking into account the possibility of carbon cycle feedbacks leading to a release of stored terrestrial carbon.»

It also depends on other factors like emissions / concentrations and e.g. carbon cycle feedback.

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.

Now, as an important aside, it is quite doubtful one could actually stabilize at 750 ppm, since work by the National Center for Atmospheric Research and the Hadley Center suggest that carbon cycle feedbacks, like the defrosting of the tundra or the die - back of the Amazon rain forest, would release greenhouse gas emissions that would take the planet to much higher levels.

Forcing is distinct from feedbacks and internal cycles like ENSO.

During that time natural cycles like the Milankovitch cycles, would trigger warming releasing CO2 resulting in a positive feedback.

«Turchin takes pains to emphasize that the cycles are not the result of iron - clad rules of history, but of feedback loops — just like in ecology.

Still, the scientists note that a number of uncertainties underpin the path of future warming, including feedback processes like the carbon cycle and clouds.

It is worth noting that wildfire incidences like this one, which are occurring across the globe now more frequently, with greater severity, and causing more damage than ever, also function as yet another feedback loop in regard to ACD: As the planet warms, arid regions dry further, causing more wildfires, which warm the planet further, and so the cycle amplifies itself.

It is intellectually dishonest to devote several pages to cherry - picking studies that disagree with the IPCC consensus on net health effects because you don't like its scientific conclusion, while then devoting several pages to hiding behind [a misstatement of] the U.N. consensus on sea level rise because you know a lot reasonable people think the U.N. wildly underestimated the upper end of the range and you want to attack Al Gore for worrying about 20 - foot sea level rise.On this blog, I have tried to be clear what I believe with my earlier three - part series: Since sea level, arctic ice, and most other climate change indicators have been changing faster than most IPCC models projected and since the IPCC neglects key amplifying carbon cycle feedbacks, the IPCC reports almost certainly underestimate future climate impacts.

I don't think it could double the human impact, releasing as much carbon as we do, or else the natural world would be «tippier» than it is observed to be, with the occasional meltdown like the PETM but not meltdowns all the time, like models do if you set them up with a carbon cycle feedback that is too strong or acts too quickly.

Could that be the positive feedback the AGW - supporters are looking for or is it a natural cycle like the ocean oscillations?

The forcing aspect of the indirect effect at the top of the atmosphere is discussed in Chapter 2, while the processes that involve feedbacks or interactions, like the «cloud lifetime effect» [6], the «semi-direct effect» and aerosol impacts on the large - scale circulation, convection, the biosphere through nutrient supply and the carbon cycle, are discussed here.
