Sentences with phrase «snowball earth because»

There are many evolutionary implications of Snowball Earth because of the island biogeography it implies.

Not exact matches

This may have occurred because the continents were clustered around the equator, and so a warm Earth would be much more vulnerable to slight cooling trends that trigger a Snowball period.

There is evidence that Earth has gone through at least one globally frozen, «snowball» state in the last billion years, which it is thought to have exited after several million years because global ice - cover shut off the carbonate - silicate cycle, thereby allowing greenhouse gases to build up to sufficient concentration to melt the ice.

There have not and will not always be ice ages because the Earth can be just too warm or ill - conditioned to respond in that manner (The Earth might also become too cold to have interglacials within an ice house period — though I'm not sure if that has ever happenned outside the Proterozoic snowball / slushball episodes).

The earth probably can't get into a snowball anymore because the sun is warmer by a couple percent since the last snowball episode 650mya and the sun just keeps growing warmer as it ages but maybe a perfect storm of super-volcano, asteroid strike, and continents arranged just right...

Because of the increase in solar irradiance over the past 600 Myr and volcanic emissions, no feasible CO2 amount could take the Earth back to snowball conditions.

Since I have discarded the forcing model because it is incapable of explaining the GHE of the Earth over a 12 month period, I had to find a model that could explain both the current behavior of the GHE and the one 20,000 years ago and the one 50 million years ago (and the snowball Earth 570 million years ago, more importantly how to recover from and snowball Earth).

Because CO2's ability to absorb IR increases linearly at low concentrations (under 100ppm) a minimal amount even absent most water vapor serves to keep the earth just warm enough to prevent a snowball earth episode most of the time.

I don't have any handy, but it is my understanding that you are correct and for example Snowball Earth was ended because of CO2 buildup from marine organisms.
