This theory is now disproven and considered obsolete. In contrast to Earth, however, global cooling remains the dominant explanation for scarp (cliff) features on the planet Mercury. After resumption of Lunar exploration in the 1990s, it was discovered there are scarps across the Moon's surface which are caused by contraction due to cooling. [5]
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
The book also illustrates Earth's eventual fate by compressing its full 12 billion-year history into 12 hours on a clock, with the first life appearing at 1:00 am, the first animals and plants appearing at 4:00 am, and the present day being 4:29.59 am. The Earth is destroyed by the Sun at "high noon", though animals and plants come to an end by ...

A total of five planets are going retrograde between May and September: Mercury, Saturn, Uranus, Neptune and Pluto. "Retrograde" is a term used to describe when a planet's orbit appears to slow.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Air bubbles and particles trapped inside the ice could also reveal why the planet’s ice ages suddenly became longer and more intense about 1 million years ago, which may have caused ancient ...
Therefore, life has impacted Earth, significantly altering Earth's atmosphere and surface over long periods of time, causing changes like the Great Oxidation Event. [244] Earth's life has also over time greatly diversified, allowing the biosphere to have different biomes, which are inhabited by comparatively similar plants and animals. [245]
