Was the Medieval Warm Period Confined to Europe?

That’s what the self-anointed ‘consensus of scientists’ claims. As noted in a previous post this week, right after the IPCC famously declared that the 1990s were likely the warmest decade of the past millennium, they stated: “Evidence does not support the existence of globally synchronous periods of cooling or warming associated with the ‘Little Ice Age’ and ‘Medieval Warm Period’” (Third Assessment Report, Chap. 2, p. 102).

But those remarkable Idsos, Shirwood, Craig, and Keith, keep reviewing studies that find evidence of the Medieval Warm Period (MWP) and Little Ice Age (LIA) not only in Europe but also in Asia, Africa, Australia/New Zealand, North America, South America, the Oceans, and even Antarctica. What’s more, the preponderance of these studies indicate that the MWP was warmer than the current warm period (CWP). The Idsos divide these studies into two categories, Level 1 Studies, which attempt to quantify the difference between MWP peak temperatures and CWP peak temperatures, and Level 2 Studies, which indicate whether the MWP peak temperatures were higher than, lower than, or the same as CWP peak temperatures.

This week on their Web site, CO2Science.Org, the Idsos review a study, published in Earth and Planetary Science Letters, that attempts to reconstruct the temperature history of the Antarctic Peninsula from ikaite crystals (an icy version of limestone) in marine sediments. [click to continue…]

Did the Senate “Definitively” Reject Efforts to Rein in EPA? A Commentary on Lautenberg’s Rant

On April 6, 2011, 50 Senators voted for S. 482, the Energy Tax Prevention Act, a bill to stop EPA from ‘legislating’ climate policy under the guise of implementing the Clean Air Act. Supporters needed 60 votes to pass the bill. “Senate Definitively Beats Back Efforts to Restrict EPA Climate Rules,” declared the title of Inside EPA’s column (April 8, 2011) on the vote. That is spin masquerading as news.

Let’s review some not-so-ancient history. In 2003, Sens. John McCain (R-Ariz.) and Joe Lieberman (D-Conn.) introduced S. 139, the Climate Stewardship Act, a carbon cap-and-trade bill. It was defeated by a vote of 43-55. In 2005, McCain and Lieberman introduced a revised version, S. 1151, the Climate Stewardship and Innovation Act. It went down in flames by a bigger margin: 38-60. In 2007, McLieberman introduced yet another iteration (S. 280), which never even made it to the floor for a vote.

In three different Congresses, the McLieberman bill died in the Senate. After these continual defeats, did Inside EPA, the bill’s sponsors, or any environmental group declare that the Senate “definitively” rejected cap-and-trade?

Of course not. Yet S. 482 garnered more votes than any cap-and-trade bill the Senate has ever debated. Sponsors of S. 482 say they will press for other opportunities to hold additional votes. The day after the Senate vote, the House passed an identical measure (H.R. 910) by a vote of 255-172, a large victory margin that should improve prospects for eventual passage in the Senate. 

Another vote could occur as early as next month when Congress debates whether to raise the national debt ceiling. House Speaker John Boehner (R-Ohio) suggested last week that legislation to raise the debt ceiling — a key priority for Team Obama and Senate Majority Leader Harry Reed (D-Nev.) – might have to include curbs on EPA’s regulatory authority (The Hill, April 16, 2011). 

Since reports of S. 482′s demise are greatly exaggerated, it is useful to examine the tactics of leading Senate opponents. Previous posts review California Sen. Barbara Boxer’s tirade against S. 482 and Montana Sen. Max Baucus’s alternative legislation to codify EPA’s ever-growing ensemble of greenhouse gas (GHG) regulations. Today’s post offers a running commentary on New Jersey Sen. Frank Lautenberg’s floor statement opposing S. 482 (Congressional Record, April 6, 2011, pp. S2170-71). If Lautenberg’s rant is the best opponents can do, they have “definitively” lost the debate. [click to continue…]

Good News on Sea-Level Rise

by Marlo Lewis on April 1, 2011

The scariest part of the global warming scare is the prediction of rapidly accelerating sea-level rise. In An Inconvenient Truth, Al Gore warns that if half the West Antarctic Ice Sheet and half the Greenland Ice Sheet melted or broke off and slid into the sea, sea levels could rise as much as 20 feet. Gore implies this could happen within our lifetimes or those of our children, stating, in the book version of AIT (pp. 204-206), that some 100 million people living in Beijing, Shanghai, Calcutta, and Bangladesh would  “be displaced,” “forced to move,” or “have to be evacuated.”

I debunk Gore’s sci-fi doomsday scenario in earlier posts.  Suffice it to say here that the UN IPCC’s 2007 Fourth Assessment Report projects 18-59 centimeters (7-23 inches) of sea-level rise by 2100. To be sure, some scientists, such as Scripps Institute of Oceanography researcher Dr. Richard Somerville, who testified recently before the House Energy and Power Subcommittee, claim the IPCC estimate is too low and that sea levels will rise by 1-2 meters.

Drs. Shirwood, Craig, and Keith Idso, our colleagues at the Center for Study of Carbon Dioxide and Global Change, have posted an editorial on sea-level rise that reviews a new study based on global tide gauge data.

The study, Houston and Dean (2011), finds that the rate of sea-level rise over the past 80 years has not accelerated and, in fact, has slightly decelerated. If I were a betting man, I’d put my money on sea level rise ending up near the low-end of the IPCC projection — about 7 inches, roughly the same amount as occurred in the 20th century. Clearly, now is not the time to sell the beach house!
