Hence, butterfly biodiversity in these areas must have increased. Furthermore, as recently discovered by Manne et al. Recommendations Mr. Chairmen and distinguished Members of the Subcommittees, based on the vast amount of peer-reviewed scientific literature that I have briefly described, I urge you to carefully consider the many real and tangible impacts that the rising atmospheric CO 2 concentration has on plant productivity and ecosystem biodiversity. These proven positive consequences of elevated CO 2 are infinitely more important than the unsubstantiated predictions of apocalypse that are hypothesized to result from global warming, which itself, may not be occurring from rising atmospheric CO 2 levels.
