leading to increased runoff and evaporation.

This cycle absorption, evaporation, rain happens everywhere there are plants.

And the process of these molecules actually escaping, that's what we refer to as evaporation.

Although we aren't actually emitting much water vapour directly, as the planet warms, evaporation rates increase, raising humidity and thickening the Earth's thermal blanket which in turn raises temperatures, which further increases evaporation rates,and so on.

The sun is overhead, maximum heating, maximum evaporation, maximum clouds, maximum rainfall, maximum opportunities for reproduction.

Satellite sensors are used by scientists to study the effect of salt evaporation on local ecology.

The sun is overhead, maximum heating, maximum evaporation, maximum clouds, maximum rainfall, maximum opportunities for reproduction.

Drought risk also increases with warming even where rainfall does not decline, increased evaporation dries out the soils.

Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas.

Salinity The Red Sea is one of the saltiest bodies of water in the world, owing to high evaporation.

In humid conditions, the air feels hotter than it actually is, because of the reduction in evaporation of perspiration.

Also, it has a lower vapour pressure than gasoline, which results in less emission through evaporation (see box 1).

Similarly, water levels would fall in low water seasons and as a result of high rates of surface evaporation in the summer season.

(i) To reduce the amount of water flowing into the water meadows in order to reduce the evaporation losses that contribute to the deterioration in water quality in the southern area resulting from the flow of water that is highly saline because of evaporation into the rivers in the low water seasons

They expressed their profound disappointment at what they described as the evaporation of political will evident in global and regional efforts toward nuclear disarmament.

Egypt fears a temporary reduction of water availability due to the filling of the dam and a permanent reduction because of evaporation from the reservoir.

As incubation proceeds, an egg will normally become lighter, and the air space within the egg will normally become larger, owing to evaporation from the egg.

Well, all land plants lose water when the pores on their leaves open up during photosynthesis, and this evaporation draws more water up through their stems.

For example, changing from overhead impact sprinklers on these pivots to drop nozzles which place the water closer to the crop and reduces evaporation and water loss.

Elevated temperatures would lead to an increased incidence of diseases and increased evaporation of surface water resulting in higher incidence of droughts, and to the bleaching of coral reefs.

lifting it out of the liquid, and having evaporation force the molecules in the liquid together, so that they jigsaw together in the same way as this crystallization works.

The evaporation of ocean water in the North Atlantic increases the salinity of the water as well as cooling it, both actions increasing the density of water at the surface.

The story of gender mainstreaming policies in UNDP is one of good starts and lost momentum or what one might call policy evaporation' intermittent declarations (see chronology above) and mixed signals.

Microplates can be stored at low temperatures for long periods, may be heated to increase the rate of solvent evaporation from their wells and can even be heat sealed with foil or clear film.

Parties indicated adverse effects on their water resources by as much as 30 per cent due to higher evaporation levels, water shortages and droughts, and an increase in water demand for irrigation (e.g. Argentina, Zimbabwe).

Management of water resources requires regular collection of information on water availability, including data on rainfall, runoff, surface storage and evaporation, much of which can be gathered in a very cost effective manner by satellite.

Global warming will increase evaporation and severely reduce rainfalls by up to 20 in the Middle East and North Africa with the amount of water available per person possibly halved by mid century in these regions.

And to think about evaporation, you just have to think about that most water molecules or the water molecules that are in that droplet they do have an attraction to eachother, we call those hydrogen bonds.

Background The Stockholm Convention POPs are highly stable compounds that circulate globally through a repeated process of evaporation and deposit, and are transported through the atmosphere and the oceans to regions far away from their original source.

For example, in Argentina aridity could expand in subtropical areas (north of latitude 40 S) due to an increase in temperature and evaporation, whereas in Armenia and Kazakhstan the arid area could expand by 20 40 per cent.

Imagine being able to make ceramics at room temperature by simply dipping something into a liquid, lifting it out of the liquid, and having evaporation force the molecules in the liquid together, so that they jigsaw together in the same way as this crystallization works.

This would reduce the current evaporation of more than 10 billion cubic meter per year, but it would also reduce the ability of the Aswan High Dam to produce hydropower to the tune of a 100 MW loss of generating capacity for a 3m reduction of the water level.
