How is the size of a whole new ozone layer change the fees in us?
Answers
Answer :
Global progress on the near-elimination of ozone-depleting substances, and trend towards recovery of the ozone is arguably the most successful international collaboration to date. In this entry we present the data on ozone layer depletion, signs of recovery, emissions of ozone-depleting substances, international agreement and collaboration, and the consequences of ozone layer depletion.
Here is an overview of some of the key points we cover below:
Global emissions of ozone-depleting substances have declined by more than 98 percent since 1986 (the year before international action was agreed)
The Montreal Protocol (and later amendments) was adopted in 1987 — since then all countries have signed on to the agreement, allowing for the dramatic decline in global ozone-depleting emissions
Ozone layer thickness declined, and the Antarctic ozone hole grew substantially from the 1980s through to the early 2000s. Through the first decade this trend largely stabilised and we now see initial signs of recovery
Ozone layer depletion increases the amount of ultraviolet (UV) irradiation that reaches Earth's surface; this can increase the risk of skin cancer, particularly at higher latitudes
The global shift away from ozone-depleting substances has also had co-benefits on the reduction of greenhouse gas emissions .
