Sentences with phrase «reduced vegetation cover»

The increased atmospheric dust load during glacial times is thought to be due to a generally colder and drier atmosphere, which increased the number and strength of dust sources through reduced vegetation cover (28), and reduced washout of suspended particles during transport (7).

While reduced vegetation cover and soil disturbance can make more sediment available for emission in dust storms, the researchers say, the widely reported link between the storm and the fighting in Syria was untested and lacked empirical support.

«Better knowledge will also provide an understanding how pressures such as invasive species, polluted runoff and reduced vegetation cover affect the ongoing health of water - dependent ecosystems in the Basin.

«Add to these factors the prevailing drought conditions that reduce the vegetation cover and the soil surface is at its most vulnerable to wind erosion.»

City rooftops covered with vegetation are seen as a way to reduce the urban heat - island effect and cut energy usage — but so far, the results have been unimpressive

The biosphere consists of animals and vegetation and normally changes relatively slowly; reduced rainfall might take years to alter vegetation cover significantly, although certain components (such as humankind) are capable of inducing quite rapid local changes (by setting oil - fields ablaze, for example).

The main reason for this warmer climate was an increased amount of energy from the Sun being received at high northern latitudes due to Earth's orbital configuration, plus Earth had an increased capacity to absorb heat due to vegetation changes and reduced ice and snow cover.

During a period like the Holocene while warming to a Pliocene - like climate, slow feedbacks (such as reduced ice and increased vegetation cover) increase the sensitivity to around 4.5 °C for doubled CO2.

North American forest vegetation types could spread with up to 4 °C warming; but with greater warming, forest cover could be reduced by savanna expansion of up to 50 %, partly due to the impacts of fire (Bachelet et al., 2001).

What it doesn't do is mitigate big floods — although soil structural improvements and increasing water holding increases vegetation cover and reduces sediment export — an important consideration for a number of reasons globally.
