Surprise, Surprise! Scientists say Earth will get a little cooler after Bali Volcano Mount Agung erupts

Since a broader segment of  the public is becoming aware of the flaws in the global warming narrative, the promoters of man-made climate change are scrambling to explain record cold and record polar ice extends. A large volcanic eruption  is a welcome explanation for low temperatures. Volcanic activity has increased in the last decade as is expected with the simultanious decrease in solar activity. Historically, the onset of a Grand Solar Minimum, and thus the increase of cosmic rays, is market by large volcanic eruptions, that then indeed contribute to further cooling. See also:

Explosive volcanic eruptions triggered by cosmic rays: Volcano as a bubble chamber

So, who doesn’t like a little bit of predictive programming? Although the experts say the Bali eruption will cause only a slight drop in global temperature, they haven’t mentioned the dozens of other volcanos that are erupting or are predicted to do so.

Here is the original article on ABC News.

Something very interesting will happen when Bali’s Mount Agung finally erupts: the Earth will become a little bit cooler.

Yep. It’s not exactly what you’d expect after a volcanic eruption, which will see molten lava spewed into the air.

But don’t get too excited, it will far from reverse the effects of global warming.

Here’s why:

Global temperatures dropped last time Agung erupted

Mount Agung last erupted in 1963 after lying dormant for decades.

When it erupted, experts said global atmospheric temperatures dropped by 0.1-0.4 degrees Celsius.

That might not sound like much, but it’s quite a significant drop when you consider the last ice age occurred when global temperatures were only 5C cooler than they are now.

So why the drop?

Because ash and toxic gas were injected into the air

According to Richard Arculus, an Emeritus Professor in geology at the Australian National University, when Mount Agung erupted 54 years ago it spewed vast amounts of ash and sulphur dioxide into the atmosphere.

That sulphur dioxide then reacted with the water vapour in the air and formed droplets of sulphuric acid.

About 10 million tonnes of those droplets accumulated in the Earth’s stratosphere the layer above the troposphere within which we live — and formed a haze.

That haze then acted as a barrier and reduced the amount of ultraviolet (UV) rays that made it from the Sun to the Earth’s surface, resulting in a cooling effect.
