In regards to natural sources, volcanoes are known to release sulfur-rich ejecta into the atmosphere and into the crater lakes that form. In 1991, the century's second largest eruption occurred on Mount Pinatubo on the island of Luzon, Philippines. Accurate predictions by local volcanologists, ...
Emissions by volcanoes and solid rocket motors can significantly enhance the local abundances of inorganic chlorine, but otherwise these sources have a small global impact following diffusion and mixing. Reactions [IX] and [X] proceed rapidly for chlorine, so that in the tropics and middle ...

The frame on the left is about controlling the climate, whereas the frame on the right is about understanding the climate. Further, the framing on the right acknowledges the futility of control. Solutions on the right focus on the basic human necessities of energy, water and food. Economic de...

It is also possible that volcanoes erupted and the lava cooled, forming landmasses. Ideas of chemical evolution Chemical evolution begins with the production of small, reduced, carbon-containing compounds like formaldehyde and hydrogen cyanide. These simple compounds reacted in the ocean to form the...
Volcanic dam lakes originate as a result of drainage that is blocked by either a volcanic mountain or its expelled lava. One example is Lake Kivu, which lies on the western side of the Central African Rift Valley (Figure 9). In the origination of this lake, seven major volcanoes dammed a...
Bromine has very strong natural (e.g., sea spray aerosol, salty surfaces in polar spring, volcanoes, salt lakes, organic brominated gases) and anthropogenic (e.g., halons, CHBr3) sources. Its chemistry is linked to that of chlorine and iodine. In the troposphere bromine plays a role for...
Lavas and volcanic rocks constituting OIB occur within the ocean basins as “intraplate volcanoes” (Fig. 9). These samples, which exhibit a wide range in radiogenic isotopic signatures, place fundamental constraints on the recycling of materials into the convecting mantle. In particular, Re/Os ...
