How the Barycentre Forces Differ: The Sun is not the centre of the solar system. The barycentre of the solar system, however, is. Both the Sun and the Earth revolve around it, generally not the centre of the Sun. This means that the motions of the two bodies around the barycentre may significantly affect the Earth-Sun distance, and […]
Reasons Irrational: The editors of Science retracted Valentina Zharkova’s paper, which can be viewed in its original form here. The paper is significant because it shows that the influence of the larger planets on the distance between the Earth and the Sun is not negligible. That means this distance changes, effecting Earth’s climate. It appears to […]
Arctic and Antarctic Pole Ice Cover is Roughly the Same What is the actual state of ice cover at the poles? Firstly, “climate” is about gradual changes in weather that occur beginning at 30-year timespans. We only have just over that many years of satellite data, giving us the capacity to even identify climatic trends. […]
Fires: What is the evidence? The chart below shows fires in South America, compared to the 2001-2018 averages. There are increases, and decreases. But importantly, the numbers only go back to 2001. Why? We just now have the technologies in place to monitor the global environment in a publicly accessible way. These measurement, visualization and […]
Plenty of snow, with the Northern-hemisphere snow mass doubled, but who needs it? All-weather-skiing Video Candide Thovex The Northern Hemisphere, because it has twice as much land mass as the Southern Hemisphere, has greater influence on the Earth’s climate and temperatures. About 40% of the surface of the Northern Hemisphere is landmass, with about 60% covered […]
Historic Temperatures The chart below is from NASA, and shows Earth’s temperatures for the last 5+ million years. The above chart shows that contrary to popular misconception, the planet may be warmer in the Holocene Period (the last 11,650 years), but it is not warmer than during the last 5 million years. In fact, the above chart […]
