The first land plants appeared around 470 million years ago, during the Ordovician period, when life was diversifying rapidly. They were non-vascular plants, like mosses and liverworts, that didn't have deep roots
A natural phenomenon that typically influences climate over a period of one to two years is sulfur-rich violent volcanic eruption.
Without any doubt, the most plentiful volcanic gas from a volcanic eruption is water vapor, which is non-dangerous.
Nevertheless, notable volumes of carbon dioxide, sulfur dioxide, hydrogen sulfide as well as hydrogen halides can also be released from volcanic eruptions. This natural phenomenon generally influences climate over a period of one to two years.
The sulfuric acid creates a mist of minute droplets in the stratosphere that reflects the incoming solar radiation, an thus is responsible for cooling of the Earth's surface.
These droplets can stay in the stratosphere for about three years, circulating all over through winds and resulting in consequential cooling all over the world.
