Stepping back from there, Hansen looks at 1940 and above: «The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but quantitative interpretation has been impossible» That's the excuse and it is laughable.

The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but quantitative interpretation has been impossible because of the absence of adequate aerosol measurements.

Thus, aerosol pollution can either warm or cool the climate, depending on its chemistry, which in turn depends on the activity responsible for the pollution.

Her research in Mexico focused more on aerosol urban pollution, providing a new direction by bringing a physical context to the pollution research.

We always thought that — apart of course from soot [15 % of climate warming]-- such aerosol pollution creates cooling — as in the case of Chinese sulfur pollution and the Asian (Indian) brown cloud — and that air quality measures over recent decades in North America and Europe are now actually a major cause of increased warming speeds there — as the actual temperature catches up on the «CO2 baseline».

The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but satisfactory quantitative interpretation has been impossible because of the absence of adequate aerosol measurements.

Second on the list is particle pollution, or aerosols, which partly counteract the greenhouse gases.

But I've been shifting my thinking based on recent conversations with some of the authors below about the feasibility of incremental management of sun - blocking aerosols, even as warming aerosols contributing to conventional air pollution are reduced.

It has been suggested that a top - down allocation approach is more appropriate for boundaries where human activities exert a direct impact on the Earth (that is, climate change, ocean acidification, ozone depletion and chemical pollution), while a multiscale approach is more appropriate for boundaries that are spatially heterogeneous (that is biogeochemical flows, freshwater use, land - system change, biodiversity loss and aerosol loading).8 Even with a top - down approach and a single global boundary, however, allocation is fraught with difficult ethical issues.

Researchers have blamed this short - lived cooling, more pronounced in the Northern Hemisphere, on a build - up of sunlight - blocking sulphate aerosols from fossil fuels, which began to clear in the 1970s as pollution controls took hold.
