A Sea Change on Climate?

Are we at the start of a softening up process that will end the Global Warming Hype?  Here and here we have reports from the BBC about the sun.

Why are they important?

Well, the second post “No Sun Link to Climate Change” was published on 3rd April 2009 and, to me, seems typical of the GW hype that has been building over the last 10-15 years, it is also plainly wrong, if the sun didn’t shine, we’d have temperatures of about -260 degrees Celcius.  Also what is not fully understood is the interaction between higher energy radiation from the sun, extreme UV for example, and how variations in this radiation may affect the climate.

The first Post “Quiet Sun baffling Astronomers” was published less than three weeks later.  For the first time the lack of sunspots has been noticed by the MSM, and despite comments about Global Warming in the piece, there is also mention of the Maunder Minimum, and the associated “Little Ice Age” that affected Europe and Continental North America.

George Bernard Shaw once said “All great truths begin as blasphemies”, currently anyone not adhering to the Hype is blasphemous, soon it will change, there will be some people that hold to the Global Warming Ideology, but even they will be forced to postpone the day of reckoning.  We’ve had a Solar “Grand Maximum”, I hope that it isn’t immediately followed by a “Grand Minimum”, a plain “Minimum” will suffice to show how wrong the Global warmers are, as well as making life much more difficult for those in higher latitudes.

Solar UV and Black Body Radiation

Data provided on websites over the last few weeks seem to indicate that, as the Sun takes a rest during solar Cycle 24, UV Radiation has dropped by about 6%.  I think this 6% is quite a drop, especially if you look and see that Total Solar Irradiance (TSI) only varies by between 0.05 to 0.1% over a Solar Cycle.  This variation in TSI is thought to be too insignificant to affect climate, but what of the UV Decrease?

It’s well known that the majority of UVB and almost all UVC Radiation is absorbed by the upper atmosphere, mainly by ozone.  But this radiation is, after absorption, re-emitted as black body radiation.  Black body radiation is taken to be emitted in any direction, which means at least 50% is passed towards space, where it may be absorbed and re-emitted again.

Associated with this drop in UV is a decrease in the diameter of the atmosphere.  NASA have said that satellites are experiencing less atmospheric drag when in low orbit (low orbit being between 120 and 200 Km above the surface).  This means that there is less atmosphere, at the edges, to intercept UV.

So what if Carbon Dioxide is not the primary driver of climate variations?  Perhaps UV plays a much larger role than previously thought. Perhaps, with a suitable lag due to the heatsink that is the oceans, we will see a much larger drop in Global temperature than is currently expected.

If you have any reliable data concerning the absorption and re-emission of UV in the upper atmosphere, I would appreciate seeing it

Climate Change vs Global Warming

Can we have an informed debate on Global Warming? The terms Global Warming and Climate change are bandied around in the press all the time, the problem is that most journalists don’t understand that they are two totally different things.

Climate Change refers to cyclic changes in long term weather conditions in a region. Basically, what that means is that if area A warms, it means that area B may cool. A great example in long term climate change is the Sahara Desert. About 8-10,000 years ago there was a North African Monsoon. That meant that the Sahara wasn’t a desert, the whole of North Africa ranged from.Jungle to Savannah,with very few areas that were very dry. Then the monsoon failed as the weather patterns moved North. Why did the patterns move North? Because the ice of the last ice age melted.

Global Warming on the other hand is what it says it says it is, an increase in temperature across the WHOLE planet. Global Warming could be caused by several things, increases in Carbon Dioxide in the atmosphere, an increase in Total Solar Irradiance (TSI), or a decrease in albedo of the planet. If you look at the average world temperature since 2000, there has been no Global Warming, however, in the same period, Australia and California in the US have both suffered exceptional droughts, Southern Spain is in a similar position as hot dry air encroaches from Africa.

While These areas have warmed and dried, other areas have cooled.
