|
|
|
| It is a gradual effect but more and more ozone depletion each year gradually stunts crop growth. |
|
| Increased UV-B radiation resulting from ozone depletion therefore persists as a significant threat to health and environment. |
|
| Following this period, the industry grew at a phenomenal rate until the late 1970s, when the question of ozone depletion became a concern. |
|
| Actions to solve ozone depletion must continue to be undertaken on a global scale, by all nations. |
|
| To date, halons have accounted for about 5 per cent of global ozone depletion. |
|
| He shared the honour with American chemists Mario Molina and F. Sherwood Rowland, who discovered in 1974 that manufactured chlorofluorocarbon gases also contribute to ozone depletion. |
|
| The refrigerants in the refrigerating circuit and foaming agents used for the insulation of the appliance shall have an ozone depletion potential equal to zero. |
|
| The Arctic stratosphere temperature remained warmer than normal for much of the winter, limiting the formation of polar stratospheric clouds that act as a catalyst in Arctic ozone depletion. |
|
| Because due to its oxygen regeneration mode the Airzone Supercracker accelerates the ozone depletion process actively after the room has been treated. |
|
| A portion of the observed threefold increase in melanoma cancer rates in Canada between 1969 and 1992 is believed to be the result of ozone depletion. |
|
| The waning of tight central control means that officials at the centre will find it tougher to implement and enforce international accords and conventions on climate change and ozone depletion. |
|
| In 1988, she made a major speech accepting the problems of global warming, ozone depletion, and acid rain. |
|
| Ozone Depletion: Care should be taken to select a product that is not installed with a blowing agent that contributes to ozone depletion or global warming. |
|
| Global changes brought on by climate change, urbanization, ozone depletion, population growth, expansion of infrastructure, migration, land conversion, pollution are altering the Earth and the way it functions. |
|
| Volcanic activity can also spur greater ozone depletion. |
|
| The use of traditional blowing agents such as HCFCs and HFCs is leading to ozone depletion and global warming, so its use is being restricted. |
|
| It has a global warming potential 296 times larger than an equal mass of carbon dioxide and it also contributes to stratospheric ozone depletion. |
|
| As previously discussed, CFCs were phased out via the Montreal Protocol due to their part in ozone depletion. |
|
| When the earth's surface and troposphere become warmer the stratosphere will cool down. Hence, the critical temperature for ozone depletion will be reached more often and the ozone layer will be weaker. |
|
| The objective of the Symposium was to share reliable information on issues related to air quality, climate and weather pattern change, ozone depletion and ultraviolet monitoring. |
|
|
|
| The heart of the system is one of the largest ammonia heat pumps in Europe-not only handy from a power standpoint, but also from an ecological perspective, as ammonia does not contribute to ozone depletion. |
|
| Scientists warn of dangers ranging from ozone depletion and greenhouse warming to forest depletion and harmful effects of very small amounts of persistent toxic substances. |
