The bottom could be in for Arctic sea ice this year which will make it the third lowest in the last 30 years.
However, in Anchorage, Alaska, the local fish wrap would have you believe the trend the sky is falling.
From the ADN.com:
“A report shows this summer’s Arctic sea ice melted to the third-lowest level since satellite monitoring began in 1979, continuing a trend of habitat loss for walrus, polar bears and other ice-dependent marine mammals.”
“Brendan Cummings, an attorney for the Center for Biological Diversity, said the announcement illustrated a trend for summer Arctic sea ice and means bad news for walrus.
‘We’re on a clear path to a seasonal ice-free Arctic,” he said. “There may be year-to-year fluctuations, but the clear path is unidirectional.’”
Yes, the overall trend for the past 30 years shows a downward trajectory. However, the temperature in the arctic is already below freezing (below) and this sure looks like we survived this summer with a greater amount of sea ice than the year before. I see that as a positive sign and remain optimistic that we are headed for recovery!
Two graphs from a paper that disputes some of the claims made by the Geological Society of Amaerica (GSA) is full of wonderful little tidbits regarding man made global warming. Here is a link to the paper.
Two graphs that stand out to me are below:
Abrupt increase in post–1945 CO2 emissions.
The above graph shows that even though there was a significant increase in the CO2 concentration, we still experienced a long period of global cooling.
Global climate change and CO2
We are seeing the same trend today. The globe is cooling and we are seeing record amounts of snowfall earlier than we have in recent memory. We are in a deep solar minimum and the Pacific Decadal Oscillation has shifted to cooling. All of the variables suggest we are going to see a significant period of global cooling on the horizon and I have a feeling that the CO2 level are going to steadily increase. Just a hunch.
The sun is once again spotless after a period of 10 days or so of sunspots present.
The current solar minimum continues and the level of activity from the sun remains very low. So what does this mean for us? Well, colder and colder weather is on the way this winter.
There is one school of thought out there that suggests that the solar winds directly impact the generation of clouds in the Earth’s atmosphere. The higher the solar winds, then the less clouds are generated resulting in higher temperatures in Earth’s atmosphere. If high solar winds mean more clouds then the converse would mean that the lower the solar winds, the more clouds are formed which would reflect the sun’s energy and result in lower temperatures.
When the Sun is active, its magnetic field is better at shielding us against the cosmic rays coming from outer space, before they reach our planet. By regulating the Earth’s cloud cover, the Sun can turn the temperature up and down. High solar activity means fewer clouds and and a warmer world. Low solar activity and poorer shielding against cosmic rays result in increased cloud cover and hence a cooling. As the Sun’s magnetism doubled in strength during the 20th century, this natural mechanism may be responsible for a large part of global warming seen then. …Read the rest of the article
Right now solar winds are a minimum and cosmic rays are at record highs. Here is a good article on cosmic rays.
This theory seems more plausible than the idea that more and more CO2, generated by man, is driving up temperatures due to greenhouse warming effects. I believe that we are heading toward much cooler temperatures in the coming months and I think that the sun is the key.
