So heat-trapping gasses trap heat! Makes sense, when you think about it.

"Carbon dioxide is a major player; without any of it in the air, the Earth would be a frozen wasteland."

Oh dear. Water vapor anyone? Adiabatic lapse rate? Snowball earth? etc. etc. Lions and tigers and bears!

p.s. but we can only "control" (read tax) CO2 so why not make the best of it...

Well, darn those climate scientists that insist on reporting good news (not from an alarmist standpoint at least...). The earth is greening apace and it appears to be mostly thanks to good old CO2. Wasn't it nice of Mother Nature to sequester away all that lovely energy in a form that we could make use of AND replenish the earth? Won't our grandchildren thank us for the abundant energy and increased food supplies that we have provided for them?

Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key drivers of LAI trends during 1982–2009. We show a persistent and widespread increase of growing season integrated LAI (greening) over25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning).Factorial simulations with multiple global ecosystem models suggest that CO2 fertilization effects explain 70% of the observed greening trend, followed by nitrogen deposition(9%), climate change (8%) and land cover change (LCC) (4%).CO2 fertilization effects explain most of the greening trends in the tropics, whereas climate change resulted in greening of the high latitudes and the Tibetan Plateau. LCC contributed most to the regional greening observed in southeast China and the eastern United States. The regional effects of unexplained factors suggest that the next generation of ecosystem models will need to explore the impacts of forest demography, differences in regional management intensities for cropland and pastures, and other emerging productivity constraints such as phosphorus availability.

Back in 2004, the properly sited, triply redundant, no-need-for-adjustment USCRN (U.S. Climate Reference Network) was established by the good folk at NOAA to verify the actual temperatures in the continental US. Despite a couple of El Nino cycles, the last 14 years have been....well..steady... The only real surprise is how we all survived the +7 F (+4C) average temperatures of 2006 AND 2012. :lol:
