Sentences with phrase «layer by phasing»

The Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.

We managed to stop putting a hole in the ozone layer by phasing out the chemicals that were causing it (cholofluorocarbons) and, as a result, the hole is closing and there are millions fewer cases of skin cancer than there would otherwise have been.

We have fairly high confidence that we observe the history of Heinrich events (huge discharges of ice - rafted debris from the Laurentide ice sheet through Hudson Bay that are roughly coincident with large southern warming, southward shift of the intertropical convergence zone, extensive sea ice in the north Atlantic, reduced monsoonal rainfall in at least some parts of Asia, and other changes), and also cold phases of the Dansgaard / Oeschger oscillations that lack Heinrich layers and are characterized by muted versions of the other climate anomalies I just mentioned.

The Montreal Protocol on Substances that Deplete the Ozone Layer («Montreal Protocol») is often cited as the most successful international environmental agreement — having successfully forced the phase - out of more than ninety - eight percent of ozone - depleting substances («ODS»), placing the ozone layer on the road to recovery by the end of the twenty - first cenLayer («Montreal Protocol») is often cited as the most successful international environmental agreement — having successfully forced the phase - out of more than ninety - eight percent of ozone - depleting substances («ODS»), placing the ozone layer on the road to recovery by the end of the twenty - first cenlayer on the road to recovery by the end of the twenty - first century.
