Sentences with phrase «slow changes in vegetation»

Naively, for example, I can imagine slow changes in vegetation leading to variation in the availability of dust & other aerosols.

Not exact matches

While the ECS factors in such «fast» feedback effects as changes in water vapor — water itself is a greenhouse gas, and saturates warm air better than cold — they argued that slow feedbacks, such as changes in ice sheets and vegetation, should also be considered.

Factoring in slow feedbacks from ice and vegetation changes would generate a significantly higher ECS, likely in the 4 to 6 C (7.2 to 10.8 F) range, the paper notes.

The silicate + CO2 - > different silicate + carbonate chemical weathering rate tends to increase with temperature globally, and so is a negative feedback (but is too slow to damp out short term changes)-- but chemical weathering is also affected by vegetation, land area, and terrain (and minerology, though I'm not sure how much that varies among entire mountain ranges or climate zones)-- ie mountanous regions which are in the vicinity of a warm rainy climate are ideal for enhancing chemical weathering (see Appalachians in the Paleozoic, more recently the Himalayas).

Based on evidence from Earth's history, we suggest here that the relevant form of climate sensitivity in the Anthropocene (e.g. from which to base future greenhouse gas (GHG) stabilization targets) is the Earth system sensitivity including fast feedbacks from changes in water vapour, natural aerosols, clouds and sea ice, slower surface albedo feedbacks from changes in continental ice sheets and vegetation, and climate — GHG feedbacks from changes in natural (land and ocean) carbon sinks.

A significant component of this key ecosystem characteristic is dependent on relatively slow processes such as rates of recuitment, mortality, and changes in vegetation composition.

Indeed, the long lifetime of fossil fuel carbon in the climate system and persistence of the ocean warming ensure that «slow» feedbacks, such as ice sheet disintegration, changes of the global vegetation distribution, melting of permafrost, and possible release of methane from methane hydrates on continental shelves, would also have time to come into play.

The remaining slow drift to lower GMT and pCO2 over glacial time, punctuated by higher - frequency variability and the dust − climate feedbacks, may reflect the consequences of the growth of continental ice sheets via albedo increases (also from vegetation changes) and increased CO2 dissolution in the ocean from cooling.

-- Other processes are very slow in change: vegetation area increase / decrease, ocean overturning rate, rock weathering,..
