Sentences with phrase «past change in atmospheric composition»

Not exact matches

Non-polar glacial ice holds a wealth of information about past changes in climate, the environment and especially atmospheric composition, such as variations in temperature, atmospheric concentrations of greenhouse gases and emissions of natural aerosols or human - made pollutants... The glaciers therefore hold the memory of former climates and help to predict future environmental changes.

The ability to hindcast the detailed changes in atmospheric composition over the past decade, particularly the variability of tropospheric O3 and CO, is limited by the availability of measurements and their integration with models and emissions data.

Changes in atmospheric composition and chemistry over the past century have affected, and those projected into the future will affect, the lifetimes of many greenhouse gases and thus alter the climate forcing of anthropogenic emissions:

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.

It's the Earth's history - how the Earth responded in the past to changes in boundary conditions, such as atmospheric composition.
