Sell your sailplane before 2030

so, even though our gliders are solar powered, we still need to get airborne. What will we as pilots be willing to give up to reduce "climate change"?

No more tows behind petrol powered towplanes? No more self-launchers with 2-stroke engines?

I look at the issue as what do I have to stop doing, give up, who do I write a check to and how much will it be to "reduce" my climate change contributions?

Just curious---thousands of years ago there was 2 mile thick ice on the property I own here in western Washington. Since this no longer is the case, doesn't it appear we have been in a global warming situation since way before the industrial revolution. Could we blame this whole thing starting on the original inhabitants of earth?

Probably not due to our Bedrock ancestors driving Stone Utility Vehicles, or herds of mammoths belching and breaking wind.

If by "original inhabitants" you mean phytoplankton, they probably helped cause some big ice ages:

No, the recent and rapid rise in temperature is driven by the recent
rise (and rapid) rise in CO2 in the atmosphere, due to the Industrial
Revolution. The original inhabitants are blameless.

Where are all the winch fans to promote winching? You can even buy solar
powered winches, but even gas or diesel winches are use lots less fuel
than towplanes. Gasoline powered self-launchers are also relatively
efficient; eg, my ASH 26E uses about 0.5 gallons to taxi out and climb
to 2000AGL. A two-stroke would not use much more, a towplane is will use
closer two 2 gallons.

Electric self-launchers are available, too :^)

Here is another view of NOAA's declaration that the hiatus is bogus:

Even the IPCC said there was a hiatus.

That's quite lengthy article - can you summarize the most important
points it makes about the NOAA paper?

My understanding is the IPCC "hiatus" remarks apply to 2012 and earlier
data, unlike the NOAA paper, which includes the hotter years of 2013 and
2014. But even if NOAA is wrong and the older IPCC report remarks are
correct, the IPCC still shows the global temperature climbing at half
the previous; ie, the "hiatus" doesn't refer to a lack of warming, only
a reduction in the rate, and using "hiatus" indicates the past higher
rate of rise is expected to resume.

Please give us a clue as to the contribution of volcanoes and how we can
mitigate their effects.

Still curious what caused the ice to melt. Any estimate as to when I can start a banana plantation here in SW Washington state? Also, kind of looking forward to launching my Electro 2 from Chehalis and routinely finding good lift immediately so I can soar the Cascades all day and return without running out of battery.

The thing about all these arguments above is that very few of us ever read anything that opposes the opinion that we have already formed, and no matter what anybody says or links to, NOBODY is going to change their mind and we are going to think those that think differently than we do are idiots, so why bother saying anything? By the way, I think we are definitely changing the weather with the dinasours we burn, and everybody that denies this is an idiot....

That's trivially true, in the sense that NO ONE denies that we are having some non-zero effect. Claims that sceptics say we don't have an effect, or that sceptics believe that temperatures have not increased (and faster from 1975-2000 or so) are pure lies or ignorance.

At question is:

- the proportion of the natural vs the human made effects in the past

- the accuracy or otherwise of future projections

- whether the effects of a few degrees increase (if they should eventuate) would overall be beneficial or harmful

- if temperatures continue to increase (not a given) AND are overall harmful (not a given), is is economically more efficient to try to prevent such changes, or to adapt to them?


In the nature of the logic in the arguments made, the alarmists have to prove every one of their linked chain of claims to be valid. The sceptics only have to show any one of them to be false.
