New paper: Clouds blown by the solar wind

This paper suggests a terrestrial impact on cloud cover from the interplanetary electric field (IEF) via the global electric circuit. A primer video on the GEC is below. Clouds blown by the solar wind M Voiculescu et al 2013 Environ. Res. Lett. 8 045032 doi:10.1088/1748-9326/8/4/045032 Abstract In this letter we investigate possible relationships between the cloud…

Current solar cycle data seems to be past the peak

The NOAA Space Weather Prediction Center has updated their monthly graph set and it appears as if the slow downside from what looks like the solar max for cycle 24. Though, it is still possible we could see a second small peak like is visible at the upper left in cycle 23. The 10.7cm radio…

How long to the 24/25 solar minimum?

Guest post by David Archibald Climate has real world consequences, and those operating in fields that will be affected by changing climate bring a different perspective to the problem of predicting what will happen. Bill Fordham, advising the grain industry in the Midwest, kindly sent me a copy of the advice he provides to his…

It’s the Sun stupid – The minor significance of CO2

Guest post by Dr. Norman Page 1 The IPCC’s Core Problem The IPCC  – Al Gore based  Anthropogenic Global Warming scare has driven global  Governments’ Climate and Energy Policies since the turn of the century. Hundreds of billions of dollars have been wasted on uneconomic renewable energy  and CO2 emission control schemes based on the notions  that…

Commitment studies belie “consensus” claim that a persistent high level of temperature forcing cannot cause continued warming

Guest post by Alec Rawls They say it all the time: even if there were some substantial mechanism of enhanced solar forcing it couldn’t be responsible for late 20th century warming because solar activity was roughly constant from 1950 to 2000. I have rounded up statements to this effect from eighteen top “consensus” climatologists, like…

NASA on the sun: ‘…tiny variations can have a significant effect on terrestrial climate.”

Researchers have considered the possibility that the sun plays a role in global warming. From NASA GSFC:  Solar Variability and Terrestrial Climate In the galactic scheme of things, the Sun is a remarkably constant star.  While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our…

IPCC Chapter 11 – Bankruptcy Protection

Guest post by David M. Hoffer IPCC reports AR1 through 4 were published in relative obscurity. ClimateGate and the emergence of the blogosphere as the primary forum for debate of the science and public policy intersection changed all that. AR4 in particular has been put under the microscope, and thoroughly discredited. It was laced with…

Solar Activity – Past, Present, Future

Essay/paper by Dr. Leif Svalgaard Abstract As our civilization depends increasingly on space-borne assets and on a delicate and vulnerable earth-bound infrastructure, solar activity and its potential impact becomes of increasing importance and relevance. In his famous paper on the Maunder Minimum, Eddy (1976) introduced the notion that the Sun is a variable star on…

The Sun has changed its character

Guest post by David Archibald A number of solar parameters are weak, and none is weaker than the Ap Index: Figure 1: Ap Index 1932 to 2026 Figure 1 shows the Ap Index from 1932 with a projection to the end of Solar Cycle 24 in 2026. The Ap Index has not risen much above…

NASA June 2012 Solar Cycle 24 Prediction

Compiled by Joe D’aleo WeatherBell via NASA MSFC The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 60 in the Spring of 2013. We are currently over three years into Cycle 24. The current predicted size makes this the smallest sunspot cycle in about 100 years. The prediction method…

Solar grand minima linked to cooling period in Europe

This is interesting. A quick cooling in Europe together with an increase in humidity and particularly in windiness was found to coincide with a long-term reduction in solar activity 2800 years ago during something called the “Homeric minimum”. The paper published in Nature Geoscience suggests that solar grand minima was the trigger for cooling of…

Talking about the weather

Harold Ambler needs a bit of a boost,  his book Don’t sell your coat is the American equivalent of Ian Plimers book How to get expelled from school in Australia, but Harold hasn’t gotten 1/10th the publicity like the Mann ‘o Climate Wars book. For example, Mann got air time on ABC in Australia recently…

Do Latest Solar Studies Confirm Upcoming Global Cooling?

Guest post by Matti Vooro I fully support the findings of  Jan –Erik Solheim , Kjell Stordahl and Ole Humlum and their very recent paper called The long sunspot cycle 23 predicts a significant temperature decrease in cycle 24  dated February 2012. The abstract reads: Relations between the length of a sunspot cycle and the…

Solar Cycle 24 Length and Its Consequences

Guest post by David Archibald Solar Cycle 24 is now three years old and predictions of the date of solar maximum have settled upon mid-2013. For example, Jan Janssens has produced this graph predicting the month of maximum in mid-2013, which is 54 months after the Solar Cycle 23/24 minimum in December 2008: For those…

Frank Lansner on Foster and Rahmstorf 2011

This is a repost from Lansner’s website, since Tamino aka Grant Foster won’t allow it to be discussed on his own website, I thought I’d give a forum for discussion here. – Anthony The real temperature trend given by Foster and Rahmstorf 2011? Posted by Frank Lansner (frank) on 17th December, 2011 (whoops, I’m not…

Are secular correlations between sunspots, geomagnetic activity, and global temperature significant?

New paper by Love et al suggests no prominent role for solar‐terrestrial interaction in global climate change. I’m providing it here for discussion. We are not convinced that the combination of sunspot‐number, geomagnetic‐activity, and global‐temperature data can, with a purely phenomenological correlational analysis, be used to identify an anthropogenic affect on climate. Abstract Recent studies…

Solar and climate- no longer taboo

Paul Hudson of the BBC writes: This is an exciting time for solar physics, and its role in climate. As one leading climate scientist told me last month, it’s a subject that is now no longer taboo. And about time, too. His article is, ahem, illuminating:
