Elevated CO2: How Sweet it is ... for Sugarcane!
We all learned back in grade school that CO2 is good for vegetation, and that plants need it to grow and construct their tissues. Might not the extra CO2 projected to be in the air by the end of the century therefore actually be beneficial for the planet’s vegetation?

The Past Half-Century of Sea Level Rise
In his testimony before the U.S. House of Representatives’ Select Committee on Energy Independence and Global Warming, NASA’s James Hansen stated “there is increasing realization that sea level rise this century may be measured in meters if we follow business-as-usual fossil fuel emissions.” Agreeing with Hansen, many people have been quick to jump on the CO2-induced global warming/rising sea level bandwagon. But how close to reality are the projections of a future sea level rise that is measured in meters?

The Global Food and Water Crisis
In a paper published in the Philosophical Transactions of the Royal Society, four British scientists report that “agriculture accounts for 80-90% of all freshwater used by humans,” that “most of that is in crop production,” and that “in many areas, this water use is unsustainable.” As a result, they say that “farmers in many countries are now faced with legislative restrictions on use of water,” noting that the Chinese government “has set a target of a reduction of 20% in water use in agriculture by the year 2020,” such that “if food security for the region is not to be threatened, this must be achieved without a loss in production.” So how is this global food and water crisis to be met and overcome?

China: Getting Greener (In the Good Sense)
Over a quarter-century ago Dr. Sherwood Idso stated in a small self-published book that if the air’s CO2 content continued to rise, it would enhance plant growth and water use efficiency to the point that semi-arid lands not then suitable for cultivation “could be brought into profitable production” and that “the deserts themselves could ‘blossom as the rose’.” How is this prediction holding up today?
