Local Arctic air pollution: Sources and impacts
Local emissions of Arctic air pollutants and their impacts on climate, ecosystems and health are poorly understood. Future increases due to Arctic warming or economic drivers may put additional pressures on the fragile Arctic environment already affected by mid-latitude air pollution. Aircraft data were collected, for the first time, downwind of shipping and petroleum extraction facilities in t...
متن کاملArctic air pollution: origins and impacts.
Notable warming trends have been observed in the Arctic. Although increased human-induced emissions of long-lived greenhouse gases are certainly the main driving factor, air pollutants, such as aerosols and ozone, are also important. Air pollutants are transported to the Arctic, primarily from Eurasia, leading to high concentrations in winter and spring (Arctic haze). Local ship emissions and s...
متن کاملResidential and Local Sources of Air Pollution
Since the early 1970s, environmental agencies have focussed most of their attention on large point sources and transport sources of air pollutants. The myriad of small sources scattered throughout suburban Australia, such as people’s heating appliances, lawnmowers and suburban restaurants, have received little attention. Perhaps this is simply because they are so dispersed or they may have been...
متن کاملArctic Air Pollution
I n the face of rapid climate change in the Arctic (increasing temperatures, earlier onset of spring snowmelt, sea ice loss, etc.), it is important to improve our knowledge about processes driving these changes. In general, climate models are able to reproduce enhanced warming in the Arctic, the so-called Arctic amplification. However, discrepancies are apparent between observations and global ...
متن کاملAnthropogenic air pollution sources
What one experiences today as atmosphere is a transient snapshot and result of its evolutionary history. Much of the development and present status was explained based both on scientific knowledge, and combined with established facts, even speculation. The planet Earth was formed around 4600 million years ago by the gravitational accretion of relatively small rocks and dust, within the solar ne...
