Has the world ever frozen over?
2024-06-05 13:16 There is a hypothesis that the Earth at one or several points would have been entirely covered by ice.  This is called Snowball Earth and is a controversial idea.  All the suggested points have their own problems.
Icehouse Earth and ice ages
2024-05-31 13:02 The climate during the last 550 million years is rather well-documented.  There have been several periods of tens of millions of years without any ice sheets.  The greenhouse effect was then considerably stronger than it is today.
What global warming means
2024-05-22 13:19 Climate change means a shifting in statistical averages.  In the case of global warming this means a shift to the warmer.  Mostly this affects areas situated closer to the poles.
Climate and seasons
2024-05-17 12:46 Climate is the average weather pattern for a place or an area.  Usually, it is the average for a period of 30 years.  Far too many mistake this for how the weather is for the moment.
Myths on snow
2024-05-10 12:15 In areas were snow is rare there are of lot of misconceptions about it.  They are probably even worse in areas where it has not snowed for generations.  Of cause everyone reading this knows what snow is.
Orders of magnitude matters
2024-03-21 12:39 It is important to keep track of which order of magnitude something has.  Otherwise one’s concepts of nature risk becoming far too erroneous.  Which in turn creates needless fear.
What is emergence?
2024-01-25 10:55 Emergence is when a phenomenon arises by itself.  This is about interactions between the different parts of the phenomenon and the surrounding environment.  As such there is no intention behind as some presupposes.
The frozen continent of Antarctica
2023-11-03 10:57 Antarctica is a continent lying around the South Pole.  However, it is not particularly symmetrical.  There is considerably less land in the direction of South America and the Pacific.
Consequences of the Earth’s motions
2023-10-27 11:07 Regardless if they are flat-earthers or not some denies that the Earth moves.  The argument is we would feel it.  The problem with this argument is we don’t feel movement in and of itself.
Flying with gravity
2023-10-25 11:09 Flat-earthers usually claim that gravity does not exist.  It is claimed to be incompatible with how things fly.  If gravity makes things fall down everything is supposed to always fall down.
