Introduction

Beginings of a Theory

Around 1900, a respected Swedish scientist named Svante Arrhenius published a series of papers and a book that included a crazy-sounding prediction. He and a colleague were studying the carbon cycle by estimating the changes in carbon dioxide ($CO_2$) produced by natural processes such as rock weathering, volcanic eruptions, and ocean absorption.

This section provides a brief overview of the earth's climate. The general concepts found in this section include the following:

• The general distinctions between weather and climate.
• Daily weather measurements are highly variable compared to long-term climate data making it difficult to detect long-term trends based on limited data.
• Long-term climate averages are the result of significant annual climate variability. Random climate variability makes detecting climate change more difficult.

This section provides a brief overview of the properties associated with the atmosphere. The general concepts found in this section are:

The earth's atmosphere is a very thin layer wrapped around a very large planet.

Two gases make up the bulk of the earth's atmosphere, by volume, they are: nitrogen ($N_2$), which comprises 78% of the atmosphere, and oxygen ($O_2$), which accounts for 21%.
Argon, ($Ar$), and other trace gases make up the remainder.

In the case of in-situ leaching (ISL) - also called in-situ recovery (ISR), or solution mining - the uranium-bearing ore is not removed from its geological deposit, but a leaching liquid is injected through wells into the ore deposit, and the uranium-bearing liquid is pumped to the surface from other wells.
In-situ leaching gains importance for the exploitation of low grade ore deposits, for its low production cost. Many new projects for uranium in-situ leaching are being planned at present.
