Editorial
Prudence Misapplied: ontrary to what is claimed in a recent editorial in the journal Science, prudence does NOT dictate that technologies be developed to help limit worldwide CO2 emissions.

The World's Longest Observational Sea-Level Record: The world's longest observational sea-level record reveals a modest increase in the rate-of-rise of sea level over the past two centuries; but this trend appears to be more a response to shifting wind regimes than to any change in temperature that may have occurred, although we do know that the earth recovered from the global chill of the Little Ice Age over this period, which could have spurred an increase in sea level as well.

Five Thousand Years of Sea-Level Change in Alaska: The results of a study of sea-level history off the coast of northwest Alaska, when compared with similar results from various other places around the world, reveals what could well be described as a mass of confusion, which is not what one would want to use as a basis for making energy policy relative to CO2 emissions from fossil fuels.

Six Thousand Years of Sea Level Change in Eastern Maine: A 6,000-year history of sea-level trends in eastern Maine reveals a significant increase in the ocean's mean rate-of-rise over the past 300 years, with the rate-of-rise since 1930 being described as "unprecedented in the past two millennia."  Do these observations confirm the climate alarmists' contention that the rate-of-rise of earth's surface air temperature over the past century has also been unprecedented in the past two millennia and is a result of the industrial activities of man?

Will There Be Enough Food?: The development of a supply-and-demand scenario for world food in the year 2050 suggests that without the help of the aerial fertilization effect of the ongoing rise in the air's CO2 content, humanity will not be able to adequately feed itself at that future date.

Climate Change and Future Crop Yields in Bulgaria: Responses of crop yields in Bulgaria to variations in temperature and precipitation experienced over the past century suggest that, even if it were to warm by 4C over the next century (there has been no warming there over the past century), crop yields would still increase, due to the many beneficial effects of atmospheric CO2 enrichment on plant growth and development.
