Global Warming and Carbon Dioxide

[tombrett]

It is a given that deforestation is contributing to the increase in carbon dioxide in the atmosphere. One remedy is to plant more trees to absorb carbon dioxide and exude oxygen. But what tree is the best one to plant to draw in the most carbon dioxide and exude oxygen? How can this be measured?

Plant the Right Tree for the Right Location
Scientists are busy studying the carbon sequestration potential of different types of trees in various parts of the U.S., including Eucalyptus in Hawaii, loblolly pine in the Southeast, bottomland hardwoods in Mississippi, and poplars in the Great Lakes.“There are literally dozens of tree species that could be planted depending upon location, climate and soils,” says Stan Wullschleger, a researcher at Tennessee’s Oak Ridge National Laboratory who specializes in the physiological response of plants to global climate change.
Plant Any Tree Appropriate for Region and Climate to Offset Global Warming
Ultimately, trees of any shape, size or genetic origin help absorb CO2. Most scientists agree that the least expensive and perhaps easiest way for individuals to help offset the CO2 that they generate in their everyday lives is to plant a tree…any tree, as long as it is appropriate for the given region and climate.

The "best" tree to plant really depends on many factors including location and level of maintenance. That being said, you might want to qualify your conditions before finding the best tree to plant.

If you want to know how to measure carbon dioxide take-in and oxygen emission, you might want to look up "how to measure amount of photosynthesis" or something along those lines. Here is a website I found that gives you several possible ways you can do that:
