An overview of volcanoes and the effects of eruptions to human lives and societies

Share via Email Mount Merapi sends clouds of gas and debris thousands of feet into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they or the substances they cause reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect.

For more examples, see my article: The thing is that of course it was a sunny day for the astronauts - you tend to forget when you see the black sky.

How do volcanoes affect the climate? | Environment | The Guardian

On Earth some of the light comes to the landscape from the sun and some reaches us indirectly from the blue sky and the clouds. On the Moon, much of the light comes from the sun, but a lot of light also comes indirectly from the landscape itself.

You can make the photos look even more like Earth by reducing the contrast - shadows are not quite so contrasty on Earth. I tried that and it worked.

The aim was to show how the Moon is as Earth like as Mars in photographs, and indeed more so, with minimal processing, not even the white balancing they use for Mars photos.

So to do additional processing to make it look more Earth like would rather defeat the point in the article. Perhaps others will do that in the future. The moisture lining your lungs would boil there.

Mars is not really significantly more "Earth like" than the Moon, I think. This is a colour enhanced Mars image as you would see it in most press photos - enhanced for the purposes of geologists, so that the rocks look like the same types of rocks under Earth illumination.

There are two ways to do this.

The ultimate climate change FAQ

The most common method is white balancing which takes the brightest patch in the scene, and adjusts it in brightness and hue until it is white. The other method, occasionally used, is natural colour which uses a calibration based on photographs of a colour swatch on Curiosity that was previously photographed on Earth.

Much brighter - which tends to make humans feel cheerful. It has no blue sky except around the sun at sunset. Also there is very little variation in colour in the landscape. I think that any Mars colonists would have a tendency towards depression just because of the rather gloomy sky and dull coloured landscape.

Elon Musk has been promoting it strongly. Stephen Hawking has also said this is an important reason to go multiplanetary. In this account of an interview with Elon Musk, the author Ross Anderson presents it as: We could swing into the path of a rogue planet, one of the billions that roam our galaxy darkly, like cosmic wrecking balls.

Planet Earth could be edging up to the end of an unusually fortunate run. Calculation indented, and coloured dark red, to make it easy to skip: Our sun has approximately 4.

That makes it about one chance in 2. There may be twice as many rogue planets as starsso that means one chance in 1. Neutron stars are even more unlikely. The chances is less than one in a billion in the next thousand years that another star gets as close as Neptune. Gamma ray bursts are possible also, but would not make humans extinct, even if very close.

Our atmosphere completely shields us from gamma rays, which is why gamma ray telescopes have to be flown in space. We can only see gamma ray bursts at all with space observatories.After being taken down twice by Blogger within a single week, we got the message: It’s Time To Go.

When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they cause.

Sorry! Something went wrong!

On May 22, , a large explosive eruption at the summit of Lassen Peak, California, the southernmost active volcano in the Cascade Range, devastated nearby areas and rained volcanic ash as far away as miles to the east.
