ABOUT THE DENVER CLIMATE STUDY GROUP: Paul Belanger and Genevieve Young, with the help and contributions of Bob Raynolds, have been leading a study group at the Denver Museum of Natural Science (DMNS), with thanks due to Kirk Johnson since the fall of 2006. The group initially started as a global warming study group for geologists, but morphed to cover a much greater range of topics. Paul, a research associate of the Museum of Nature and Science, has a research background in paleoclimate using foraminiferal microfossils and stable isotopes to generate data to interpret past climates. The meeting format waned off and but the group continued to grow and is now a Yahoo discussion group (since September 2009): http://tech.groups.yahoo.com/group/DenverClimateStudygroup/. (MORE)

The next row of 4 panels:

There's a lot of push-back those that don't want to believe in global warming that temperatures have been flat the last 17 (or whatever years) without looking at the whole picture. Ignored is the heat going into the ocean (jpeg) (i.e. water - that has a much greater heat capacity than air). The 4 panels below look at a longer range; IMHO it helps to look at the bigger picture not cherry pick the time window to be dismissive. As a geologist, I'm sometimes embarassed to be associated with geologists who apparently ignore CO2 proxy data that indicate the influence CO2 has on Earth's climate in the recent past (Pliocene for example) when Plate Tectonics nor Milankovitch orbital parameters have not been significantly different and yet the climate was clearly warmer (references below; see Royer and/or contact me).

This shows the last 3 years (last panel) and prior 5 decades - note how the east Pacific reflects cooler temperatures due to stronger La Nina conditions causing greater than normal upwelling and cooler temperatures: click here for reference article

These diagrams show the heating of the last century by Northern and Southern Hemisphere; the downturn at the end of the left diagram is related to the East Pacific cooling explained in the panel to the left: click here for reference article

This is a clever diagram to show a consistent warming shift
through time; NOTE - it's global NOT just over land. Do note the
last panel does show a cooling shift to the left - but don't count on it

I recently saw in the NPS Bryce Canyon’s “The Hoodoo”: “Nobody likes bad news and because so much of climate change is (perceived as) bad news, many prefer to ignore, be skeptical, or just plain deny valid data” – parenthetical addition mine. I wish we could recognize the issues and instead of ridiculing and dismissing climate scientists, accept the science and discuss what should be done – it’s complex: it involves economics, future energy directions, population, socio-economics. Climate change is part of nature, except we are causing it at a rate unparalleled in Earth History; its sustainability for our way of life!"

  • HOME a film by Yann Arthus-Bertrand (1hour 33 minutes long - you will not be disappointed:
    IT'S MESSAGE (esp. 1:20' ON) "It's too late to be a pessimist"

    about: http://www.goodplanet.org/:

    TO ANYONE WHO DOUBTS HUMAN IMPACT: An extraordinary film Home by Yann Arthus-Bertrand (h/t to Daniel Bailey). Yann Arthus-Bertrand is famous for his aerial photography and this film features a dazzling series of aerial shots of the Earth. Each shot is a piece of art. Stringing it together is a compelling story narrated by Glenn Close. It speaks of the Earth's beauty and the balance of nature's ecosystems. It documents how humans have disrupted the balance and our unsustainable trajectory. But like any good climate message, it ends with hopeful and positive actions already occurring.
