Significant environmental change (either climate and/or land use) has the potential to change radically the channel type and destabilise the adjacent valley floor.
To judge by yesterday's interview in the Evening Standard, Mr Hammond hasn't heard of either climate change or carbon reduction, failing to mention either.
Long before either climate change or the obesity epidemic were on the national scope, Wendell Berry's "Unsettling of America" made the case for a way of life and a kind of agriculture that might have averted both — and could still make an important contribution to solving these problems.
These results caution against using C4 plant abundance as a proxy indicator of either climate or pCO2 without an adequate understanding of key controlling factors.
Cosmogenic nuclides on river terraces and in caves measure river incision and glacial valley lowering rates and can reveal responses to either climate or tectonics.
Persistence for three of the tree species (lodgepole pine, Douglas-fir, subalpine fir) throughout the 90-year simulation under either climate change scenario was afforded almost entirely by sites that grew increasingly unfavorable for new establishment (Fig. 5).
It is often difficult, therefore, to estimate to what extent changes in species procurement are correlated with either climate fluctuations or deliberate cultural choices in terms of subsistence behavior.
However, SDMs built using either climate or climate plus landscape variables yielded very different predictions of future species range shifts and, hence, of the geographical patterns of change in species richness.
One knowledgeable agency observer speculates on the EPA's failure to take action on either climate change or stiffer regulation of chemical facilities: "They're gun shy," he says.
The Senate's failure to act on either climate or the immediate needs of Gulf Coast communities shows just how tight a stranglehold Big Oil has on Congress.
And since I loathe heat and humidity, living in northern and southern hemispheres means I can maintain a comfortable existence by escaping either climate's summer heat.
