Sentences with phrase «where small changes in temperature»

Not exact matches

Thanks for publishing this, there are folks who denigrated the work of scientists that claimed a solar - climate (temperature) link because the variability in solar energy output just wasn't enough to explain the temperature swings, and perhaps they now realize that there could be another mechanism - similar to a transistor where small changes in gate voltage can affect large changes in power transmission - whereby solar activity can create significant effects on temperature.
Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentiTemperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentitemperature changes will cause conduction / diffusion of heat that partly balances the differential heating.
It is also true that small changes in a particular direction (e.g., warming) may be beneficial where larger changes are harmful — i.e., there are optimum temperatures for many crops that have determined where they are now grown, based on thousands of years of evolution.
The same small change in temperature, however, would reduce food production at lower latitudes, where many countries already face food shortages.
A small localized change in surface temperature can cause a convection burst (thunderstorm) and a large increase in convection height, improving both reflection of incoming solar radiation, and conveying sensible heat to a higher altitude where it can then escape to space via radiative processes with far less interference.
In the final analysis we are arguing about a temperature record made by volunteers with little oversight over many generations on continents where a truly massive amount of land use change due to industrialization and agriculture and where said land mass is but a small fraction of the globe's surface one might wonder why we bother with it.
Specifically, is the climate dominated by positive feedbacks, such that small CO2 - induced changes in temperatures are multiplied many times, or even hit a tipping point where temperatures run away?
