EARTH 103: Earth in the Future. Background Increasing levels of CO2 in the atmosphere are slowly causing the surface of the ocean to become more acidic.

EARTH 103: Earth in the Future

This is because the ocean absorbs some of the CO2, forming a weak carbonic acid. At present, the ocean absorbs about a third of fossil fuel emissions, but this amount is likely to increase to 90% in the future. Over the last century, the average pH of the ocean has decreased, and there are hints that the current levels are beginning to impact organisms that make their shells out of the minerals aragonite and calcite (both composed of CaCO3). Coral reefs that are made of the mineral aragonite are highly vulnerable to ocean acidification. Changes in atmospheric CO2 and consequences on the oceans.

The following video provides a thorough overview of the potential impact of acidification on the oceans. Chemistry 101 As we discussed in Module 5 on the Carbon Cycle, the absorption of CO2 in the ocean forms weak carbonic acid (H2CO3). Credit: National Academies. 1. Introduction to Climate Change.

Human Population

A Disappearing Planet. Given the natural extinction rate, we would not expect more than one mammal species go extinct per century.

A Disappearing Planet

However according to the scientists, 1,469 are currently in danger of extinction in that time. Primates are highly at risk, especially the lemur family. Rhinos, bears, and big cats are also in trouble. According to the natural extinction rate, we should not see more than one reptile extinction per century. However, 1,163 are currently at risk for extinction in that time. According to the natural extinction rate, we should not see more than one amphibian extinction per century. According to the natural extinction rate, we should not see more than one bird extinction per century.

Native Plant Information Network

Our goal is to assemble and disseminate information that will encourage the sustainable use and conservation of native wildflowers, plants and landscapes throughout North America. The Native Plant Information Network (NPIN) is designed to inform a broad audience ranging from members of the general public such as homeowners, wildflower enthusiasts, and gardeners to practicing professionals such as botanists, land managers, and government personnel. You can dig a little deeper into NPIN history with the links below or start your native plant journey with the Explore Plants menu to the right.

Mr. National Tree Benefit Calculator. Clean Coal Technology fact or fiction. Many politicians are touting clean coal technology as a viable fuel source.

Clean Coal Technology fact or fiction

There is a rising chorus of people from science, alternative energy businesses and industry who dispute these assertions. In the United States, we burn coal to make electricity. The emissions are waste from burning coal that have already had many negative consequences including: several kinds of local air pollution, air pollution drift, forest destruction by acid rain, mercury pollution of waters and the problematic disposal of toxic fly ash.
