Här är några länkar som pekar på samband mellan ozonuttunning, ökad växthuseffekt och klimatförändring. Bl a förstör ökad UV-strålning till följd av uttunning av ozonskiktet havens fytoplankton och kan därmed minska havens förmåga att ta upp koldioxid: "Furthermore, there are a number of possible feedbacks between an increase of UV radiation and climate change. For example, increases in UV radiation – e.g., as a consequence of stratospheric ozone decline – affect ocean phytoplankton, which may lead to an enhanced greenhouse effect by reducing carbon dioxide uptake in the oceans. In summary, the enhanced greenhouse effect is likely to delay the recovery of the ozone layer, and the ozone layer strongly influences the wind regime in the stratosphere that, in turn, affects the global climate. Therefore, an understanding of the composition of the stratosphere, its chemistry and dynamics, and the changes that are occurring, is even more relevant than in the past if we are to make meaningful predictions about the future climate and surface UV radiation levels." http://www.google.com/search?q=ozone+depletion+climate&hl= sv&rls=com.microsoft:sv:IE-Address&rlz=1I7SUNA&start=60&sa=N Nedanstående länkar till en bok där frågan ställs om ozonuttunning och växthuseffekt kan samverka för att orsaka en klimatförändring.

Abstract The atmosphere displays modes of variability whose structures exhibit a strong longitudinally symmetric (annular) component that extends from the surface to the stratosphere in middle and high latitudes of both hemispheres. In the past 30 years, these modes have exhibited trends that seem larger than their natural background variability, and may be related to human influences on stratospheric ozone and/or atmospheric greenhouse gas concentrations. The pattern of climate trends during the past few decades is marked by rapid cooling and ozone depletion in the polar lower stratosphere of both hemispheres, coupled with an increasing strength of the wintertime westerly polar vortex and a poleward shift of the westerly wind belt at the earth's surface. Annular modes of variability are fundamentally a result of internal dynamical feedbacks within the climate system, and as such can sh ow a large response to rather modest external forcing. The dynamics and thermodynamics of these modes are such that strong synergistic interactions between stratospheric ozone depletion and greenhouse warming are possible. These interactions may be responsible for the pronounced changes in tropospheric and stratospheric climate observed during the past few decades. If these trends continue, they could have important implications for the climate of the 21st century.
