One of the latest tactics some global warming alarmists have employed is to compare their activism to struggles of the Civil Rights Era of the 1960s. Actor Edward Norton compared the "symbolic" Earth Hour of March 29 to infamous Selma's "Bloody Sunday" in an appearance on CNN's "Larry King Live," and again on NBC's "Today."

But this time, one of the movement's leaders, former Vice President Al Gore, made a similar comparison. Testifying for before a congressional committee on April 24 in Washington, D.C., Gore rated his activism to that of the civil rights movement.

"I believe this legislation has the moral significance equivalent to that of the civil rights legislation of the 1960's and the Marshall Plan of the late 1940's," Gore said. "I am here today to lend my support to one of the most important pieces of legislation ever introduced in the Congress."

However, for CNN's "Lou Dobbs Tonight" host Lou Dobbs, there was some irony in that remark, being that Gore's father was a longtime senator from Tennessee that voted against civil rights legislation.

"Well, as you just heard Lisa [Sylvester] report, the former vice president claimed that this climate change legislation has the moral significance or equivalence of the civil rights legislation of the '60s and the Marshall Plans," Dobbs said. "Well, an interesting note - Gore's father, Senator Al Gore, Sr., like many southern Democrats at the time voted against the Civil Rights Act of 1964."

Dobbs also noted during the segment prior Earth Day prognostications in his report, all of which didn't quite come true.

"Well, Earth Day, this week, and here are some words of doom and gloom from leading scientists, academics and authors on our climate and environment associated with Earth Day," Dobbs said. "Journalists Peter Collier wrote, ‘One to two million people per year will be starving to death during the next 10 years.' Biologist Paul Ehrlich claimed that most people are going to die in ‘the greatest cataclysm of mankind.' Harvard biologist George Wall said, ‘If we don't take act now, civilization will end between 15 or 30 years.' And ecologist Kenneth Watt claiming that in 15 years, ‘Air pollution will reduce the amount of sunlight reaching earth by one- half.' I want to point out if I may that each and every one of those quotes were from the first Earth Day in 1970, nearly 40 years ago."

The CNN segment highlighted a ClimateDepot.com report that global warming skeptic Lord Christopher Monckton was denied the opportunity to testify before the House Subcommittee on Energy and the Environment.

"The House Democrats don't want Gore humiliated, so they slammed the door of the Capitol in my face," Monckton told the online magazine Climate Depot," CNN correspondent Lisa Sylvester said.

And as Climate Depot's Marc Morano explained - most Gore's doom-and-gloom forecasts are to occur in the distant future.

"If you look at Gore's testimony today, he was talking about what could, might and may happen 50 to 100 years from now," Morano said to CNN. "He was not talking about reality."
