The climate is changing and we’re not

Deniers will of course scoff, but a new report by EPA, “Climate Change Indicators in the United States” follows 24 U.S. and global indicators of climate change. Some of the indicators show a very clear trend, others not so much. All of the findings are based on rigorous scientific protocols, but then, good science has not been enough to nullify delusional belief thus far. It’s like a belief in Atlantis, ghosts or vampires. Once the dogma takes hold, no amount of reason or logic will sway the true climate denial dupe.

Anyway, for what it’s worth, here are a few of the key findings in the EPA report.

  • Several studies have shown that the amount of heat stored in the ocean has increased substantially since the 1950s. Ocean heat content not only determines sea surface temperature, but it also affects sea level and currents.
  • In the United States, greenhouse gas emissions caused by human activities increased by 14 percent from 1990 to 2008. Worldwide, emissions of greenhouse gases from human activities increased by 26 percent from 1990 to 2005.
  • Average temperatures have risen across the lower 48 states since 1901, with an increased rate of warming over the past 30 years. Seven of the top 10 warmest years on record for the lower 48 states have occurred since 1990, and the last 10 five-year periods have been the warmest five-year periods on record.
  • The frequency of heat waves in the United States decreased in the 1960s and 1970s, but has risen steadily since then.
  • In recent years, a higher percentage of precipitation in the United States has come in the form of intense single-day events. Eight of the top 10 years for extreme one-day precipitation events have occurred since 1990.
  • Glaciers in the United States and around the world have generally shrunk since the 1960s, and the rate at which glaciers are melting appears to have accelerated over the last decade. Overall, glaciers worldwide have lost more than 2,000 cubic miles of water since 1960, which has contributed to the observed rise in sea level.

You can view the entire report online at http://www.epa.gov/climatechange/indicators/pdfs/ClimateIndicators_full.pdf or you can get a hard copy by phoning  the National Service Center for Environmental Publications (NSCEP) at 1-800-490-9198. At least we know that Bugle readers keep an open mind and prefer to listen to facts rather than PR and chicanery.
