Sentences with phrase «e.g. glacier surface»

Data from real glaciers are required both to parameterise a model, for which values from similar glaciers in other parts of the world may be used, e.g. glacier surface albedo (Cuffey and Paterson, 2010), and to define variables for the study glacier.

Not exact matches

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

I'm very convinced that the physical process of global warming is continuing, which appears as a statistically significant increase of the global surface and tropospheric temperature anomaly over a time scale of about 20 years and longer and also as trends in other climate variables (e.g., global ocean heat content increase, Arctic and Antarctic ice decrease, mountain glacier decrease on average and others), and I don't see any scientific evidence according to which this trend has been broken, recently.
