What was the highest temperature ever recorded on the surface of Earth?

The record the article is referring about seems to be the same as registered at Guiness World Records: On 13 September 2012 the World Meteorological Organisation disqualified the record for the ...

Relationship between natural disaster and global warming, in the media

First thing first: It is very hard, if not impossible, to attribute a single anomalous weather event to climate change. The weather exhibits a huge amount of natural variation. The recent spate of ...

What is the northernmost/southernmost city that receives no snow?

On the North American west coast, Coos Bay, Oregon is the northernmost place I can find, of any significance, that gets no snow. Astoria, Oregon gets 2.5 cm of snow per year. Coos Bay is at 43.4 ...

Does snow melt on ice?

Yes, a layer of snow on top of ice can melt in some circumstances. For example, one active area of climate research involves analyzing the optical properties of sea ice as they relate to incoming ...

Should I worry about copper pipe outside attracting lightning strikes?

The easiest thing to do to make your copper pole safe would be to ground it and disconnect the lights from your house wiring when they aren't in use (if they are plug-in lights and not solar). This ...

What causes "Smokey" weather?

One possible cause will be an inversion. Normally, air temperature decreases with an increase in altitude, but during an inversion warmer air is held above cooler air. An inversion traps air ...

The Pacific Northwest is about to endure the hottest temperatures in recorded history. What is the atmospheric setup causing it?

One might say it's a "perfect storm", heat-wave version. High pressure aloft and wind patterns driven by a low-pressure trough on the ground conspire to raise surface temperatures. According ...

What would be a reasonable set of thresholds for flood severity classes?

One existing classification for return period events is minor and major flows, which basically classifies floods into those that the storm network (pipes and small conveyance network) is designed to ...

Why don't forest fires in Western Australia get as much attention as forest fires in the southeast of the country (including SA)?

Forest fires, and natural disasters in general, get attention when they affect people. Bush fires outside of metropolitan Perth or far away from populated areas do not affect many people. Therefore, ...

What happens if it rains above the boiling point of water?

It will depend on how the temperature and humidity change as the raindrops approach the bottom of the column. If the air is hot and dry, the drops will evaporate. If it's hot and humid enough, they ...

Is there consensus amongst climatologists that cold weather extremes are caused by global warming or human influence?

It is common sense. The more energy in the Atmosphere the most intense will be the stirring up of it, so you will get cold polar air and hot tropical air moving around further and producing extreme ...
