Sentences with phrase «from changes in atmospheric composition»

Not exact matches

But that doesn't mean that the consequences don't exist, from changes in marine food webs to shifts in oceanic and atmospheric chemical composition.

Changes in atmospheric composition from human activities are the main cause of anthropogenic climate change by enhancing the greenhouse effect, although with important regional effects from aerosol particulates (IPCC 2007).

However, overall sensitivities of lifetime to changes in atmospheric composition vary widely from model to model.

Consider the facts: the climate system is indicated to have left the natural cycle path; multiple lines of evidence and studies from different fields all point to the human fingerprint on current climate change; the convergence of these evidence lines include ice mass loss, pattern changes, ocean acidification, plant and species migration, isotopic signature of CO2, changes in atmospheric composition, and many others.

I was continuing to root through the AGU FM abstracts and came across this from Christina Ravelo et al. (paragraphed for easier digestion by dyspeptic elderly bunnies): «The response of climate to past changes in atmospheric greenhouse gas composition can be used to assess Earth System sensitivity.

Kevin Trenberth says: «Rather, climate models that run with and without the human - induced changes in atmospheric composition demonstrate that human warming has emerged from natural climate variability since about 1970.»

Rather, climate models that run with and without the human - induced changes in atmospheric composition demonstrate that human warming has emerged from natural climate variability since about 1970.

Specifically, has anyone here framed the issue in terms of, «changing the composition of a substance changes its properties» — and then related that to activities ranging from cooking, to metallurgy, to biotechnology, to the atmospheric effect of taking lead out of gasoline?

the reason the period of the last 1000 years isn't much of a priority in terms of paleo simulations is that you need some specified change to external forcing (solar, atmospheric composition) or bottom boundary conditions (like continents moving around) to get a simulation that is different from present.
