And thus, we keep discussion about a few percent here or there instead of accepting that we never can be accurate in our predictions but should be looking at the overall trend. Ofcourse, we are in a bad way, the overall signs are clear. What do you do when you are driving a car.and.you see a child playing with a ball? You slow down and anticipate the worst, that the kid suddenly will cross the street. So, why do we.continue full blast with our emissions? Let's sort out the 25 issue later, just accept that it is bad and reduce. But.... We are building coal fired powerplants like crazy, we burn more wood, we keep flying long distance to our holidays and do not seem to be willing to take a serious step back... No, let's discuss about the percentages. And then what? Just continue because maybe it is 24.8? Get real, accept that we will never know exactly how it works and just like the weather predictions: live with the uncertainty but anticipate the worst.

1. If the iceblock is under water, it is likely that the surface area is reduced. Then, drain. Because you need to maximise the surface area.
2. Try to keep the meltwater but make sure the water has a big area (large tub), then several things are happening: evaporation of the water results in heat loss. And the bigger area increases the heat transfer.

Indeed, All this nonsense spreading around is upsetting. YES, ofcourse there are disadvantages. So... Start using less power in order to minimise the negative effect. As somebody who has been living on solar power for over 20 years now, I can tell you that it is amazing how little power you actually need. E.g. neighbours have 2 fridges and a freezer. We survive with a small (camping-style) fridge/freezer. Do you need this huge plasma TV? Do you need to wash at 90 degrees C? We survive very comfortably with a 5kWh battery set which has been in service now for 6 years and not degrading because we take care.... Do you need this big SUV while a smaller car can do 5 liters/100km?? Or use excess solar/wind power for an electrical car? And then, when you have minimized your consumption, then select the source with minimum environmental impact and for the time being, that is solar/wind. Or sometimes hydro power.. But please stop this Facebook stuff and have a look at realistic cost/benefits. ALL costs and ALL benefits, not just slogans.
