Climate Change: New Evidence for the Hockey Stick



The so-called "hockey stick" chart--which shows a rapid rise in global temperature is a mainstay in arguments that humans are causing climate change--a center of attacks by climate change denialists. A new study offers a revised chart that conforms the hockey stick chart. Climat Feedback explains the development:

The contentious ‘hockey stick’ climate change graph has again been upheld as broadly accurate, doubtless to the rage of climate denialists/sceptics/whatevers.

A team led by Michael Mann of Penn State University has looked at a whole range of proxies for surface temperatures over the last 2,000 years in an attempt to counter criticism of the graph, which showed a long ‘handle’ and a sharp upturn (the blade).
Their findings? As the Christian Science Monitor puts it: “It still looks a lot like the much-battered, but still rink-ready stick of 1998. Today the handle reaches further back and it’s a bit more gnarly. But the blade at the business end tells the same story.

”The previous hockey stick had been accused of relying too much on data from tree rings so this PNAS study may silence some of the critics when it appears later.

I have spoken with several climate change deniers. What I find is that in the face of overwhelming evidence, they simply feel they must deny in order to bear no responsibility for what has happened.

When pressed, one denier stated that even if it was true, it was God's will anyway.

I hate it when people blame God for their poor behavior. I can't believe more Christians aren't upset when they hear that response to tragic events.

We are the only beings on the planet with brains that allow us to think things through--I suggest we start using those brains to figure out a solution to this climate mess. How will God feel if we completely destroy his creation?

I have to agree with Michael. I think people deny what they don't want to have to be responsible for, but since we are all to blame we must get past that point and move to a resolution.

is not the fault of nature if not ours, these climate changes we have in the whole world is because of us, and we are the only ones who can solve these issues

Giles Fraser on Gay Marriage

Image
The Rev. Gileas Fraser offers thoughtful piece on gay marriage on BBC Radio this morning: Back in the sixteenth and seventeenth centuries, as the Book of Common Prayer was being put together, marriage was said to be for three purposes: First, It was ordained for the procreation of children … Secondly, It was ordained for a remedy against sin, and to avoid fornication .. Thirdly, It was ordained for the mutual society, help, and comfort, that the one ought to have of the other, both in prosperity and adversity. How do these three concerns relate to the prospect of gay marriage? The third priority insists that marriage is designed to bring human beings into loving and supportive relationships. Surely no one can deny that homosexual men and women are in as much need of loving and supportive relationships as anybody else. And equally deserving of them too. This one seems pretty clear. The second priority relates to the encouragement of monogamy. The Archbishop of Canterbury himself has rig...

Religious Map of United States

This map shows which of eight major Christian denominations has a plurality in the United States, county by county. the map obviously does not capture the full story given the rich diversity of Christian denominations in the United States, but it does show much of the regionalization of the major denominations. The map and analysis can be found here . Hat Tip to my friend Jim .

New Climate Change Study

What a coincidence. Yesterday, I blogged about the James Dobson et al "We Get It" effort to deny climate change. Yesterday, NASA scientists issued a new report showing a strong causal link between human activity and climate change. Here is the Science Daily report: A vast array of physical and biological systems across the earth are being affected by warming temperatures caused by humans, says a new analysis of information not previously assembled all in one spot. The effects on living things include earlier leafing of trees and plants over many regions; movements of species to higher latitudes and altitudes in the northern hemisphere; changes in bird migrations in Europe, North America and Australia; and shifting of the oceans' plankton and fish from cold- to warm-adapted communities. "Humans are influencing climate through increasing greenhouse gas emissions, and the warming world is causing impacts on physical and biological systems attributable at the global scal...
