Cornell scientists convert carbon dioxide, create electricity ITHACA, N.Y. – While the human race will always leave its carbon footprint on the Earth, it must continue to find ways to…
Lets Cook Limestone to Raise Atmospheric CO2 to 1000ppm
Guest essay by Eric Worrall The world has a CO2 problem – there is not enough free CO2 in the atmosphere, to maximise food production, alleviate world hunger, green deserts,…
El Nino drives fastest annual increase on record of carbon dioxide
From the UNIVERSITY OF EXETER The human-caused rise in atmospheric concentration of carbon dioxide is being given an extra boost this year by the natural climate phenomena of El Niño,…
The latest EIA CO2 emissions data shows that the U.S. is not a significant contributor to increasing global CO2 emissions.
U.S. overall energy related emissions are 12% below 2005 levels, and electricity generated related emissions are that of 1993. Guest essay by Larry Hamlin EIA data and analysis shows that…
