Welcome to the 142nd Daily Field Note! Here you find the top post of the day, one covering each scientific field that is included by Geopolis. Since these authors put a lot of effort in writing a good post they surely deserve the extra exposure.

Geopolis is a project to promote and connect authors who write in the fields of global sciences. You can read more about the project and how to join here:

Geology: The Climate Effects of Volcanic Eruptions

Original post by @yissakhar

Volcanic eruptions affect climate on many time scales. To understand the human influence on climate it is necessary to appreciate these natural influences.

Ecology: The real costs of clean energy and technology - Part 1: my battery needs cobalt and lithium

Original post by @snowyknight

Can you be a hippy, Earth loving, environmentalist and use modern technology? So thinking about the total costs of energy and technology, "clean" or otherwise (perhaps coal) is important.

A post by @procrastilearner (with associated comments) got me thinking. The discussion there went into the end of oil and coal and future technologies. New "clean" technologies are often proposed to be the answer to how we can save the planet.

Stop driving our petrol (gas)-fueled cars, trucks, and bus, and lets use clean electric cars that are powered with batteries...

Archeology: EGYPTOLOGY: Science in Ancient Egypt, Part #3

Original post by @laylahsophia

In my two previous posts about science in Ancient Egypt, I gave you a short introduction to Astronomy & Mathematics, and Geography, Geology & Biology. In this article I wanna show you the power of innovation and technology of this advanced ancient culture which will cover in the same time the subjects of Physics and Chemistry and will also give you a more detailed view into the work of archaeologists and how they come to their conclusions about the historical cultural development in past times...
