Not exact matches

Smil has forced climate advocates to reckon with the vast inertia sustaining the modern world's dependence on fossil fuels, and to question many of the rosy assumptions underlying scenarios for a rapid shift to alternatives.

Modern human - driven forces, like climate change and pollution, are «orders of magnitude more destructive than what early humans were doing,» Lyons said, but even at the dawn of human civilizations, people were certainly having major — and unprecedented — ecological impacts, she said.

In addition, our deficient understanding of aerosol forcing also hinders our ability to use the modern temperature record to constrain the «climate sensitivity» — the operative parameter in determining exactly how much warming will result from a given increase in CO2 concentration.

Future forecasts of climate models forced with greenhouse gas levels as high as modern ones tend to result in Pliocene - like climate (~ 3 million years ago) when sea levels were estimated to be 14 meters higher than they are today.

Regardless, the modern climate record contains very little variability that is not confidently explained by the forces outlined in articles like this.

And this should give any reasonable person — and society — concern about the consequences of forcing the climate into a state that is without precedent in modern society.

Future forecasts of climate models forced with greenhouse gas levels as high as modern ones tend to result in Pliocene - like climate (~ 3 million years ago) when sea levels were estimated to be 14 meters higher than they are today.

Title: «Shortwave forcing of the Earth's climate: Modern and historical variations in the Sun's irradiance and Earth's reflectance» Author, P.R. Goode, E. Pallé Journal: Journal of ATMOSPHERIC and SOLAR - TERRESTRIAL PHYSICS DoP: Sept 2007 DOI: 10.1016 / j.jastp.2007.06.011

The failing of modern climate science and the IPCC lies in their insistence that climate is a linear function of the forcings.

It follows that CO2 alone provides nearly 30 W / m2 of radiative forcing, much larger than the ~ 4 W / m2 when you double it in the modern climate.

However, we conclude that the imprint of this Modern Maximum (e.g. Earth climate forcing) would essentially result from time - integration effects (system inertia), since exceptionally high amplitudes of the solar magnetic cycle can not be invoked anymore.

But seriously, I look at your use of terms like «forcing», and «feedback», and «equilibrium climate sensitivity», and «CO2 control knob», and I feel sorta like a modern redox chemist watching a bunch of biologists trying to study the cell by measuring its «phlogiston» characteristics.

The IPCC states that the modern warming decadal warming, +0.55 °C, was at least 50 % caused by humans - thus, it is highly likely that natural climate forces were responsible for the other 50 %, say a +0.27 °C of the modern warming.

Shortwave forcing of the Earth's climate: modern and historical variations in the Sun's irradiance and the Earth's reflectance, P.R. Goode, E. Palle, J. Atm.

In fact, this analysis makes it clear that over 50 % of the modern global warming could be a direct result of the same natural climate forces that warmed the world prior to the 1950s.

Shortwave forcing of the earth's climate: Modern and historical variations in the sun's irradiance and the earth's reflectance.

«Third, in a period when ocean basins were similar to modern, ice age climate sensitivity to pCO2 changes is underestimated by climate models even when long term changes in solar forcing and ice sheet size and distribution are taken into account, implying that internal positive feedbacks are stronger than previously thought.»

Despite the fact that both the models and the YD hypothesis indicate changes in heat transport can affect the global temperature, and in the case of the YD so dramatically temperatures go against the forcing trend, you are steadfast in your beliefs that it is impossible that any long term trend in heat transport can be affecting modern climate.

It is now very clear that you are fundamentally concerned with bolstering your prior commitment to the denial of the dominant role of CO2 forcing in modern climate change.

But the important problem for modern climate science is to predict and to measure the response of other atmospheric variables (temperature, humidity and cloud) to a climate forcing.

But what is * not true * is the belief that the climate system * now * is capable of internally - forced behaviour that explains modern observations.

For modern warming, we know that all component of the climate system are gaining energy, so the reason for the warming is mostly forced (a).

Anne, that might be the case if there were not an adequate understanding of the natural forcings (levels of solar activity and vulcanism) causing the MCA and of anthropogenic forcings (greenhouse gases) largely causing what you call the Modern Climate Anomaly.

It seems to me that if one wants to make an apples to apples comparison about the relative importance of different climate forcing factors, then one ought to be looking at their differential impact under modern conditions.

The injection of stratospheric aerosols from the eruption of Mt. Pinatubo was noted as the first modern test of a known radiative forcing, and indeed one climate model accurately predicted the temperature response (Hansen et al., 1992).

Within a modern complex climate model, forcings other than solar are not imposed as energy flux perturbations.

says you'll be forced to: Address living well without modern so - called conveniences; think about «which expenses actually make me happy and improve my family's quality of life» and which ones «just eat away at my time and money»; and, importantly (it is Climate Week, even though really every week is climate week, recognized or not), start really thinking about what your carbon footprint is reallClimate Week, even though really every week is climate week, recognized or not), start really thinking about what your carbon footprint is reallclimate week, recognized or not), start really thinking about what your carbon footprint is really like.
