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 ...
We don't know if the display supports local or global dimming, though, something that would go some way toward enabling HDR support. Nevertheless, LG says the monitor is capable of 10-bit-per-channel color output, which is once again a little odd in light of the 99%-of-sRGB color gamut. The company ...
Instead, it dims the whole screen when needed – a technique known as frame dimming or global dimming. It's a technique that's effective in deepening the black level or letterbox bars in dark scenes and worked well with our review sample to reduce several spots of backlight clouding, too. Unlike TVs with ...
»Das global dimming hat den Treibhauseffekt eine Zeit lang maskiert, seit den 1980er Jahren wird er aber in seiner ganzen Dimension sichtbar«, stellte denn auch Wild fest. Sein Beispiel: In der Schweiz seien die Gletscher zwischen 1973 und 1985 lediglich um ein Prozent geschrumpft, zwischen 1985 ...
The PA27AC supports HDR10 and meets VESA's baseline DisplayHDR 400 standards, so its peak luminance is 400 cd/m² and there's global dimming on tap. When displaying a static scene or image, as when working up a photo, the PA27AC can sustain 320 cd/m² of brightness. Asus claims that users will ...

Dr Stanhill called it "global dimming", but his research, published in 2001, met a sceptical response from other scientists. It was only recently, when his conclusions were confirmed by Australian scientists using a completely different method to estimate solar radiation, that climate scientists at last woke up to ...

Two wrongs make a right. "Global warming" masks "global dimming," or visa versa. That's why this "sky is falling" hysteria about global warming ...
The most knowledgeable folks among us — scientists in the relevant fields — really don't know how anthropogenic global dimming could alter ...
It's called global dimming or cooling. Particulates are obscuring the sun and altering rainfall patterns. Real time data can be found here: ...
Searching for Real Global Temperature Trend, part 2 – Global Dimming: if aerosol cooling is underestimated, then warming trend is higher.
ANYONE remember global dimming? About 30 years ago, climatologists noticed a disconcerting trend in the amount of sunlight reaching ...
There has recently been a lot of talk and a lot written about global warming. Increasingly, skeptics are coming to realize that global warming is ...
Dammed if we do and dammed if we dont...its called global dimming..if we stop burning fossil fuels right now the global temp will rise 2 plus degrees within weeks because the greenhouse gases we produce creates an umbreslla of coal sulphates, water ...
In regard to "polluting the climate change debate" this includes a full paragraph devoted to DiCaprio hypocrisy (not a basis for rational debate), a slant on China's poisonous particulate infused atmosphere (called global dimming and ironically a ...
Some notable geohacking proposals include cirrus cloud seeding to reduce reflectivity, stratospheric particle injection for solar radiation management, sulphur-aerosol injection to induce global dimming and simple solutions like tropical reforestation ...
L'andamento italiano riflette quello di altre aree del Pianeta con la successione di due fasi: un'iniziale riduzione della radiazione solare (global dimming), seguita da un successivo aumento della stessa (global brightening). Molte ricerche sono ...
High-end Danish AV electronics manufacturer Bang & Olufsen used CEDIA Expo to show U.S. custom electronics designers and installers that it's still in the video display game by presenting two series of 4K Ultra HD including models in its BeoVision 14 ...
Why don't they realise the effect of global dimming - the ability of pollutants to reflect solar heat back into space and cause cooling - before we cleaned up our industries we were mystified as to why despite the greenhouse effect the planet was ...
Another degree, at least, is there, but hidden by 'global dimming' by aircraft con-trails and particulate pollution.
"Besides a vast number of VisionClear technologies, BeoVision 14 is based on a blinking backlight with global dimming and provides an improved uniformity and overall noise reduction and increased sharpness in details," forklarer Bang & Olufsen i et ...
Sony ha presentato a Londra i TV Bravia serie ZD9. I nuovi modelli si posizionano al vertice della gamma e quindi su una fascia superiore rispetto a XD94, XD93 e a tutti gli altri prodotti. I tagli disponibili saranno tre, tutti con dimensioni molto ...
And partly it's because of something called 'Global Dimming' which basically is a phenomenon wherein the Earth's atmosphere has become so dark that solar radiation fails to penetrate it effectively thereby reducing warming from solar radiation.
And that is why Ethiopia's drought that killed millions is being blamed on Western industrialism and pollution. That is why 70,000 Europeans died in the summer of 2007; likely from one country cleaning up its sulphate emissions !
Piers Forster, James Hansen, Gavin Schmidt, Alan Robock, Michael Mann, Ken Caldeira, Stefan Rahmstorf, Chris Forest, Gabriele Hegerl, Hans Joachim Schellnhuber, Jonathan Gregory, Drew Shindell and Andrei Sokolov share their thoughts, and gut ...
Factors like global dimming - and all forms of short-lived aerosol reflection - these create their own thermal inertia. Matthews also does not disagree with the thermal inertia that Hansen had coined in 2005 - only with a 'wide (journalistic ...
In part 16 of our temperature trend series we take a better look at one of the main reasons almost everyone still underestimates climate urgency: 'Thermal inertia' of the climate system - a delay between the moment of emissions of CO2, and the moment ...
We want to find the 'really-real trend line' - that is the temperature trend if you would correct for thermal inertia and important masking factors like global dimming - that is the temperature value that tells us something about the actual equilibrium ...
Happy Earth Day! To celebrate the occasion, I wanted to feature a trailer for a documentary about climate change and what we can do to save this big, beautiful planet we all live on.
Global dimming, i.e., a gradual reduction of direct irradiance on the Earth's surface, was observed from 1861 until at least 1990.
When this happens, large-scale temperature effects can take place due to increased albedo (solar reflection) and global dimming. What is also striking is that volcanic activity seems to sometimes come in clusters - making volcanoes very useful for ...
