Sir David Attenborough: The Truth About Climate Change
By admin
The legendary broadcaster and naturalist Sir David Attenborough was long unsure about the causes of the observed climate warming. In his documentary, The Truth About Climate Change, he sheds doubt and explains what convinced him. Climate models based on purely natural processes such as solar activity and volcanic eruptions fail to explain the observed change in Earth’s climate in the latter part of the 20th century. Models factoring in the human impact, that is, the increase of carbon dioxide in the athmosphere, depict the transpired warming accurately, however.

Global warming: How will Arctic ecosystems change?

As Arctic sea ice melts at an unrelenting pace, marine biologists are trying to understand how ecosystems in the North Pole region may change and how the increase in hunting territory available to killer whales in the Arctic could seriously affect the marine ecosystem balance.

Climate change has long-since ceased to be a scientific curiosity, and is no more than just one of many environmental and regulatory concerns.

@g1geo1g No thank you, not interested in having a fake debate with a denier troll. Go log into your other sock accounts and have a nonsense debate with yourself
Nightversionn, still you evade the question. Can you explain why CO2, which overlaps in a minor way spectrally with water which controls all other aspects of climate, can dominate. And why do models popularly depict the incorrect coincidence of Earth’s black body signature with the absorption of CO2, ( which, incidentally, overlaps with water vapour anyway)?

Abstract
Two natural components of the currently progressing climate change are identified. The first one is an almost linear global temperature increase of about 0.5°C/100 years, which seems to have started in 1800–1850, at least one hundred years before 1946 when manmade CO2 in the atmosphere began to increase rapidly.”
“Most glaciers around the world (alpine and Greenland ice-sheet glaciers) have been melting as part of the long-term warming trend since the end of the Little Ice Age in the 1700s The recession of glaciers started long before anthropogenic CO2 levels rose. Since the IPCC says that anthropogenic CO2-based warming has only had an effect since the 1970s the recession of glaciers cannot be due to anthropogenic CO2-based global warming.”
“Norway: Geologist/Geochemist Dr. Tom V. Segalstad, a professor and head of the Geological Museum at the University of Oslo and formerly an expert reviewer with the UN IPCC: “It is a search for a mythical CO2 sink to explain an immeasurable CO2 lifetime to fit a hypothetical CO2 computer model that purports to show that an impossible amount of fossil fuel burning is heating the atmosphere. It is all a fiction.”
Another denier sock puppet account, go figure
” In the Ross Sea. Low pressure over the eastern Weddell Sea later in the month had the same effect there. Sea ice for the Antarctic in December 2011 was the fifth-highest for that month in the satellite record; the highest December extent occurred in 2007. Overall though, Antarctic sea ice extent remained below or near normal for most of 2011. “
@g1geo1g the fact you and other are deniers isn’t political, it’s FACT
@g1geo1g I get, you’re another denier sock puppet that was trying to engage in another fake debate with your other sock puppet. gotcha
Where you differentiated between other comments and those of someone specific and pronounced ‘He’s a denier’, and thereby put responders into one of two groups ‘acceptors and deniers’, thats why I mentioned politics. Still you evade the question.
@g1geo1g What exactly was the point I said where YOU said, “point taken”
Hello???
@g1geo1g I asked you is there anything political in what I said???
Nightversionn, why are you so intense. You really take this personally. I asked a question and again you don’t answer. What do you understand about all the things you report. It’s a simple question. Do you process any information yourself or do you just believe what others say?
What point taken?? What politics? Are you high right now?
@g1geo1g Are you talking to me?
Ok, point taken, maybe I’m a bit confused by the politics here. I want the truth. When I ask you about your understanding of the ‘process’, whereby CO2 overpowers an overwhelming, controlling force like water at the mercy of a quantum linked Sun, you go quiet on me.
@g1geo1g Are you being sarcastic? Nice one? He’s a climate denier despite ALL EVIDENCE to the contrary. Anybody who still asserts that global warming isn’t caused by man is a fucking imbecile
Nice one david222444. Every description I’ve read about the importance of CO2 as a greenhouse gas has ‘strangely’ suggested that it’s potency lies in the fact that it absorbs infrared at the peak wavelength of Earth’s black body emissions and quotes this peak at 15um or 600cm-1. This is the peak of a black body at 193K, or -80deg C. Also ‘for clarity’ water is omitted. The black body peak for the Earth’s mean temperature of 15degC, 288K, is 10um. Check it yourself via black body spectrum, Wien
@Nightversionn Well show us the proof.
???
. . .
@david222444 An overwhelming mass of evidence supports the hypothesis of anthropogenic climate change. Thousands of scientists have been working over the past decades to prove beyond all reasonable doubts that human activities are changing the climate, duh?
