leading to increased runoff and evaporation.

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

This condition had apparently promoted more intensive oxygen evaporation, which subsequently saturated the standard safety valve.

Sample results indicate that water evaporation rates in the boreal (northern) forests of central Canada are extremely low.

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

Due to very low evaporation rates, the thus generated droplets form metallic spheres that remain nearly unchanged in size for their orbital lifetime.

The planet likely featured more dry regions than Earth, but once had enough water and geographical variability to host life and guard against rapid evaporation.

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.

International Commission on Irrigation and Drainage (ICID) control of evaporation from soil and open water surfaces in water harvesting structures impact of drought on irrigated agriculture food security and sustainable development in Africa.

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).

Solutions being looked at include better water distribution and slowing down evaporation from the soil, but also spraying the plants with a protective mix of clay and water and developing varieties more resistant to dry conditions.

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.

But if you do not look at grasslands but look down into them, you find that most of the soil in that grassland that you've just seen is bare and covered with a crust of algae, leading to increased runoff and evaporation.

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.

By 2100, one billion to three billion people worldwide are expected to suffer from water scarcity. 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.

Parties also identified the following impacts increase in the frequency and intensity of surface run off soil erosion drought pollution and decreases in surface water run off and groundwater with negative impacts on agricultural lands, grasslands and terrestrial and aquatic ecosystems and higher rates of evaporation from hydro reservoirs affecting reserves available for power generation.

According to Iran, the oil well fires in Kuwait and evaporation from millions of barrels of crude oil spilt into the Persian Gulf as a result of Iraq's invasion and occupation of Kuwait produced large quantities of soot and sulphur, much of which were deposited in several areas of the Southern Provinces in the form of black rain.

Since atmospheric emissions entering the sea through precipitation over the open ocean are normally diluted and diffused, the immediate effects of atmospheric pollutants such as smog, toxic air pollutants and acidic depositions entering the sea through precipitation (most of the earth s evaporation (86 per cent) and precipitation (78 per cent) takes place over the oceans) have not yet been identified by the international community as requiring urgent remedial action.

The Chinese government must, therefore, strike a balance between protecting China s export sector and preserving its national welfare. The dilemma that officials face is that the impact of a fall in exports as a result of RMB appreciation will be felt acutely and immediately, whereas the large welfare losses due to the evaporation of the value of China s foreign exchange reserves will be borne by society as a whole but not immediately.
