Scientists Said Sun Caused Global Warming – 1998

June 6, 2014

By Paul Homewood




Back in 1998, the BBC reported:


Climate changes such as global warming may be due to changes in the sun rather than to the release of greenhouse gases on Earth.

Climatologists and astronomers speaking at the American Association for the Advancement of Science meeting in Philadelphia say the present warming may be unusual – but a mini ice age could soon follow.

The sun provides all the energy that drives our climate, but it is not the constant star it might seem.

Careful studies over the last 20 years show that its overall brightness and energy output increases slightly as sunspot activity rises to the peak of its 11-year cycle.

And individual cycles can be more or less active.

The sun is currently at its most active for 300 years.

That, say scientists in Philadelphia, could be a more significant cause of global warming than the emissions of greenhouse gases that are most often blamed.

The researchers point out that much of the half-a-degree rise in global temperature over the last 120 years occurred before 1940 – earlier than the biggest rise in greenhouse gas emissions.

Using ancient tree rings, they show that 17 out of 19 warm spells in the last 10,000 years coincided with peaks in solar activity.

They have also studied other sun-like stars and found that they spend significant periods without sunspots at all, so perhaps cool spells should be feared more than global warming.

The scientists do not pretend they can explain everything, nor do they say that attempts to reduce greenhouse gas emissions should be abandoned. But they do feel that understanding of our nearest star must be increased if the climate is to be understood.



After taking billions in grant money, scientists now know better.

      Yes, we must have a panel to discuss how we can bilk billions of more dollars out of governments to further our goal of buying mansions…er I mean proving that man made global warming is real! Al Gore

    Poor BBC! Whatever happened to objectivity? This article is a museum piece.

      So contemporaneous articles supporting anthropogenic warming are equally invalid?

      Poor Ed. Logically supported argument is hard.

        Tot up all the BBC articles you can find for the last ten years that air evidence contrary to CAGW, then do the same for the alarmist ones, then get back to me to tell me the BBC is balanced. Also see 28-gate. Don’t use your computer, though… you’re ruining the atmosphere!

    A BBC report from before the days of advocacy.

    The article states “Sun most active now for 300 years”. Something wrong here.
    We have just passed a sun spot maximum (every 11 years) and it is a fact that there have never been so few sun spots as during this cycle. The Sun has been well asleep!
    Also, the Solar Flux, which is being stringently measured daily, has been remarkably low this time around. Anyone involved in Radio communication will know that a high Solar Flux is a prerequisite (together with low K and A-levels, i.e. geomagnetic activity) for long distance communication – and this has been a big problem during the present spot-maximum. Flux has generally been low and A/K levels high.
    Back to the drawing board.

    A word to the wise… There is no money to be made by espousing this “sun causes climate change” foolishness.
