Sentences with phrase «temperatures in a feedback loop»

Sea ice melt impacts local and global temperatures in a feedback loop.

Not exact matches

With huge stores of carbon in peat, the fear is that rising global temperatures could cause the release of massive amounts of CO2 from the peatlands into the atmosphere — essentially creating a greenhouse gas feedback loop.

A built - in digital feedback loop equalizes the charging times by reconnecting the temperature - dependent current source to a capacitor of a different size — the size of this capacitor is directly proportional to the actual temperature.

In a negative feedback loop a point is reached at which extreme changes in temperature are halteIn a negative feedback loop a point is reached at which extreme changes in temperature are haltein temperature are halted.

The probability of accelerated temperature increases is very high, especially due to feedback loops from events such as peat and tundra melting in boreal forests.

In short, whatever the initial climate sensitivity is to a doubling of CO2, I just can't buy off on this positive feedback loop idea that says that temperatures are going to spin out of control once we pass over some «tipping point» that only seems to exists in some scientist's theoretical modeIn short, whatever the initial climate sensitivity is to a doubling of CO2, I just can't buy off on this positive feedback loop idea that says that temperatures are going to spin out of control once we pass over some «tipping point» that only seems to exists in some scientist's theoretical modein some scientist's theoretical model.

That in itself can lead to higher temperatures in a positive feedback loop.

Since CO2 and CH4 are greenhouse gases, atmospheric temperature is likely to increase in turn, resulting in a feedback loop with more permafrost thawing.

This small increase in H2O then increases atmospheric temperature since H20 is a strong GHG which then allows more H2O to be absorbed etc (positive feedback loop).

Temporary natural El Nino events do cause a spike in upper troposphere temperatures but then return to a lower temperature state (no positive feedback loop).

At a recent debate at Oxford University, organized by the OU Engineering Society, I gave the undergraduates an argument from process engineering (which you will find in outline in my Union College presentation, and in more detail in my Hartford College lecture) to the effect that the closed - loop temperature - feedback gain in the climate system (i.e., the product of the Planck parameter and the net sum of all unamplified feedbacks) can not much exceed 0.1, implying at most 1.3 K of warming per CO2 doubling, compared with the IPCC's central estimate of 3.3 K.

There's good evidence to support periods of much higher levels of Co2 in the past and that in itself suggests that we live in a self regulating system, not an ever increasing temperature feedback loop like the dodgy IPCC models claimed.

The new study, published in Nature Geoscience, identified a negative feedback loop in which higher temperatures lead to an increase in concentrations of natural aerosols that have a cooling [continue reading...]

If warming and CO2 «trigger multiple feedback loops» then how did the dinosaurs not all burn to death in global temperatures 10C higher and CO2 of 2000 - 3000 ppm?

Tack on, without the large and growing number of self - reinforcing feedback loops we've triggered recently, the 5 C rise in global - average temperature 55 million years ago during a span of 13 years, and it looks like trouble ahead for the wise ape.»

Early models showed that once ice reached tropical latitudes, a positive feedback loop would take hold, in which ice cover would lead to lower temperatures, which would add more ice cover, which would lower temperatures even more.

«open loop» — it has no feedback mechanism and any change in energy levels will result directly in a change in temperature — this is more or less the position of Team AGW.

«The trend in sea ice decline, lack of winter recovery, early onset of spring melting, and warmer - than - average temperatures suggest a system that is trapped in a loop of positive feedbacks, in which responses to inputs into the system cause it to shift even further away from normal.

Or, more ominously, how a change in the gas level initiated by humanity might be amplified through a temperature feedback loop.

The new study, published in Nature Geoscience, identified a negative feedback loop in which higher temperatures lead to an increase in concentrations of natural aerosols that have a cooling effect on the atmosphere.
