Rob Quinn, Newser: A recent United Nations report warned that the world had just a dozen years left to avoid some of the most catastrophic effects of climate change. A new study suggests that assessment was far too optimistic. Researchers using a new method to calculate the amount of heat absorbed by the world's oceans say the buildup of heat over the last 25 years is 60% higher than previous estimates, meaning the world is warming significantly faster than expected, the BBC reports. While we have just learned that the oceans have warmed so much that the world is going to have catastrophic climate change, see photos added to article of what some people are doing to deal with this crisis. How many will stop dead in their tracks to stop using fossil fuels? Can the world be saved?
Don Bogard, radio-geochemistry, nuclear geochemistry, planetary science: Most people express concern about melting polar ice sheets. But, it is the global warming, ongoing for over 200 years, that is the main culprit. And much of such warming earlier on was not caused by CO2, and that warming may still be present. If 3.1 mm/yr rise were to continue to year 2050, it would add another ~4 inches to sea rise. Most sea shores have much more to worry about from tides and waves.
Terry Gross, NPR, David Owen, New Yorker: We're going to start this interview with the subject of David Owen's new book, "Where The Water Goes," about the Colorado River. The river and its tributaries supply water to over 36 million people in seven states - Colorado, Wyoming, Utah, New Mexico, Nevada, Arizona and California - and irrigates close to 6 million acres of farmland. Owen writes about the engineering feats that make all that possible and the legal and environmental battles surrounding the river. The Colorado River is so overtaxed that by the time it reaches the U.S.-Mexico border it's dry. This question can be repeated for rivers and ground water around the world. Each river that is overused destroys the land and water ecology. There are solutions, if we look far enough.
Paul Driessen, CFACT, Roger Bezdek: Saltwater intrusion clearly has been an increasing problem across much of Chesapeake Bay. Climate alarmists attribute this danger to human fossil fuel use. Reality is much different. At least for the Chesapeake region, Houston-Galveston, Texas, area, Santa Clara Valley, California, and other places around the globe, the primary cause of seawater intrusions is not rising oceans – but land subsidence due to groundwater withdrawal and to “glacial isostatic adjustments.”
Alex Epstein, Forbes: Thanks in large part to our use of hydrocarbon (fossil) fuels, which release carbon dioxide when combusted, CO2 now constitutes, by popular estimates, .01% more of the atmosphere than it did in 1850. Does that constitute a large and growing threat of rising sea levels?
Sherwood Idso, Keith Idso, Craig Idso - There is considerable current concern that the ongoing rise in the air's CO2 content is causing a significant drop in the pH of the world's oceans in response to their absorption of a large fraction of each year's anthropogenic CO2 emissions. In light of these diverse and independent assessments of the two major aspects of the ocean acidification hypothesis -- a CO2-induced decline in oceanic pH that leads to a concomitant decrease in coral growth rate -- it would appear that the catastrophe conjured up by the world's climate alarmists is but a wonderful work of fiction.
Patrick Moore is the Chair of the Energy, Ecology and Prosperity program at the Frontier Centre for Public Policy. He has been a leader in the international environmental field for over 40 years. Dr. Moore is a Co-Founder of Greenpeace and served for nine years as President of Greenpeace Canada and seven years as a Director of Greenpeace International. The pH of the world’s oceans varies from 7.5 to 8.3, well into the alkaline scale. It is therefore incorrect to state the oceans are acidic or that they will become acidic under any conceivable scenario. The term “acidification” is used to imply that the oceans will actually become acidic. It is perhaps just short of propaganda to use the language in this manner.
Tom Wysmuller, Lecturer at Colderside.com: He examines whether there is a link between atmospheric CO2 and Sea Level and discusses what a 1% reduction in CO2 would mean for sea level. See his website: www.colderside.com for interesting questions and answers on man-made climate change.
Howard Cork Hayden is Professor Emeritus of Physics at the University of Connecticut. His interests include science education without political agendas, atmospheric and climate science, energy for society (fossil fuels, nuclear, hydro, wind, biomass, photovoltaics, and solar heating). In this article he explains basic laws of physics about measuring heat stored in the oceans. This is not what the media and organizations with political agendas are describing
Harrison Schmitt. The scientific rationale behind the Environmental Protection Agency’s proposed massive intrusion into American life in the name of fighting climate change has no scientific or constitutional justification. This has no basis in observational science as has been discussed previously relative to climate history, temperature, and carbon dioxide.
In addition, oceans of the Earth play the dominant role in the perpetuation and mediation of naturally induced change of global climate.
