Sentences with phrase «global atmospheric pollution»

By the late 1980s it became clear that global atmospheric pollution causing both the greenhouse effect and the hole in the ozone layer had become critical threats to life on earth (Henderson - Sellers & Blong 1989).

Not exact matches

There is also growing understanding of the links between atmospheric problems such as local air pollution, acid rain, global climate change and stratospheric ozone depletion.

A curious detail also shown by the study is a reduction in atmospheric pollution from lead during the last few decades, which, as Lozano concludes, «suggests that the global measures taken to reduce lead emissions, such as the use of lead - free gasoline, have helped to reduce the levels of this metal in the atmosphere.»

To simulate the interplay of global climate with regional pollution conditions, the scientists turned to two of the world's leading atmospheric models, both based at NCAR and developed through broad collaborations with the atmospheric science community.

Such transformational changes in attitudes would help foster the necessary institutional reforms and technological innovations for providing the energy sources that have negligible effect on global climate, atmospheric pollution and eco-systems, thus protecting generations yet to be born.

A new study by Stanford University atmospheric scientist Mark Jacobson has revealed that worsening air pollution and higher carbon dioxide emissions go hand - in - hand - the results suggest intensifying global warming will increase the number of smog - related deaths.

Climate change, rising atmospheric carbon dioxide, excess nutrient inputs, and pollution in its many forms are fundamentally altering the chemistry of the ocean, often on a global scale and, in some cases, at rates greatly exceeding those in the historical and recent geological record.

Several of the most disconcerting atmospheric problems include smog and air pollution, which are responsible for a higher incidence of respiratory diseases and death; acid rain, which contaminates numerous other ecosystems such as watersheds and forests; and finally, one particularly serious issue, climate de-stabilization caused by the accelerated rate of global warming.

The Global Greenhouse Gas Reference Network measures the atmospheric distribution and trends of the three main long - term drivers of climate change, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as carbon monoxide (CO) which is an important indicator of air pollution.

That lack of immediate concern may in part stem from a lack of understanding that today's pollution will heat the planet for centuries to come, as explained in this Denial101x lecture: So far humans have caused about 1 °C warming of global surface temperatures, but if we were to freeze the level of atmospheric carbon dioxide at today's levels, the planet would continue warming.

Scientists of the time disagreed on whether the greatest global risk was cooling by atmospheric pollution or greenhouse effect warming.
