global dimming

When it rains, it pours. Today, the drops from the sky take the form of new displays conforming to AMD's FreeSync 2 adaptive-refresh-rate specifications. We reported earlier on BenQ's EX3203R, and now AOC joins the party with its AG322QC4. The 31.5" diagonal size of the panel is about the only thing ...

What's particularly notable about such attempts is that many of them — global dimming by way of atmospheric spraying of reflective chemicals, for instance — wouldn't actually do anything to lessen the intensifying global weirding and warming, but would simply add another layer of complexity on top, ...

Stratospheric aerosol injection consists of injecting sulfate aerosols into the stratosphere with aircraft or balloons to create a global dimming effect. “This technology is absolutely terrifying. We may actually need it, but then, who do we want to decide. That's where this society-wide discussion has to take ...

Climate engineering also creates a phenomenon known as “global dimming.” Solar obscuration (blocking the sun) is a primary stated objective of geoengineering / SRM programs. Though “official sources” claim much of the global dimming phenomenon is a result of aircraft “condensation” trails, this ...

When you take in the effects of reducing pollution, thus reducing global dimming, up to 1 degree C could be coming to Earth, and the effects of methane coming from the melting permafrost around the Arttic, you need to be looking more to 6 degrees. National Geographic did a documentary, called 6 degrees ...

Little research has been conducted into how ecosystems would respond to prolonged global dimming. Some researchers also worry that spraying sulfur dioxide into the high stratosphere could damage the ozone layer, though recent research has suggested this risk is smaller than once thought.

This would involve injecting sulfate aerosols into the stratosphere to deflect incoming sunlight back into space, thereby resulting in global dimming. This is basically what happens after a large volcanic eruption: Sulfur dioxide is thrown into the stratosphere where it becomes sulfuric acid, which prevents ...

Amidst a storm of climate records here at Bits of Science we're searching for 'The Real Global Temperature Trend'. Today is part three of the series – the second episode about 'Global Dimming'. Although worldwide aerosol pollution is slowly declining (see the first graph of this article, below), it could still ...

This is referred to as 'global dimming'. Global dimming has a separate climate effect. Let's say the aerosol shade consist of both light-coloured sulphur particles and dark-coloured soot – something resembling the Asian Brown Cloud. Then, by this pollution haze, some of the solar radiation is reflected, but a ...

For the first 30 years or so, less sunlight reflected from Earth back into space, a phenomenon known as “global dimming”. Sulfate aerosols in the atmosphere pointed the finger at human involvement. When coal is burnt, for instance, sulfur dioxide (SO2) molecules released into the atmosphere form tiny ...

Global dimming was a real and serious problem, but smaller and easier to tackle than global warming. As factories and power stations cleaned up their acts – at least with respect to smog and soot – dimming slowed and, in some places, reversed. From about the mid 1980s onwards, the developed world ...

Dear EarthTalk: I've heard of global warming, of course, but what on Earth is “global dimming?” — Max S., Seattle, WA. EarthTalkGlobalDimming Global dimming is a less well-known but real phenomenon resulting from atmospheric pollution. The burning of fossil fuels by industry and internal combustion ...

The discovery of global dimming can be traced to Gerry Stanhill who was, in the 1950's, a research worker studying irrigation water requirements. His task was to use climate measurements, in particular those of solar radiation, in order to determine the amount of water crops would require. He collected data ...
