Have they done risk analysis on hydrogen running cars? They'd be big changes to car engine structure right?

I'm guessing they will be. Heavy Goods Vehicles they will be looking at as well. A lot of companies have changed from Diesel to Bio-CNG to cut back on CO2 emissions.

Batteries for Trucks are no good due to the size and weight it would take to move them.

New ships and tankers will be moving away from fossil fuels and running on the likes of Methanol. Will be more expensive to run for a good few years but the price will come down when production ramps up.

Hydrogen will be pushed in the car manufacturing industry. I'm saying that because you just need to look at the companies who are looking to mass produce Hydrogen ( Blue at first )

Looks like our friend Tipp has bought into the work of Dr. William Happer, who was part of the "CO2 Commission" and who wrote a document called "Carbon Dioxide Benefits the World." Unsurprisingly, this organization receives funding from major right-wing organizations.

Their arguments are specious.

--CO2 is good for plants, blah blah blah

Plants depend on many things, such as water and nutrients; increases in CO2 have not been "better" for crops/plants (that's due to agricultural engineering), and plants will suffer due to heat stress. Who cares.

--CO2 goes through cycles of increase/decrease.

Yes, but those cycles happened well before humans occurred. What we are seeing now is unprecedented levels of CO2:

--Humans only produce a tiny bit of CO2 relative to nature blah blah blah.

This tiny bit influences the carbon cycle, as evidenced even in the simplest of cartoons:

--Water vapor is the most common greenhouse gas and the cause of global warming, not CO2.

Water is a shape-shifter and can go from a liquid to gas to solid; yes, water vapor is the most predominant greenhouse gas, but its presence varies across time and space and with temperatures. CO2 doesn't do this, it is a gas no matter the temperature; it remains constant whether its a hot day at sea level or a cold spike at the top of a mountain. And just because water vapor is the most common greenhouse gas it doesn't mean it is the common cause of global warming--it amplifies warming but didn't cause the warming trend, CO2 is the actual culprit. Even though water vapor generates "more heat" (has more radiative forcing) than CO2, water vapor affects temperatures locally, not globally, and when temperatures change it often falls to the earth as rain or freezes into snow, no longer becoming water vapor. There is a time-scale affect going on as well: water vapor can influences temperatures over a short period of time (as in diurnal or seasonal cycles) but CO2 has been steadily accumulating over the long term and is exacerbated by the last 200 years of human activities. I conclude this water vapor argument is stupid (gee look, my joints hurt, I'm infertile, and I'm going blind...as blood is the most common liquid in my body it must be the blood causing this, not the trace amounts of lead that have built up since childhood...I mean how much damage could a small amount of lead do to me relative to my 7 liters of blood...lead is 100% natural).

Hydrogen is a highly inflammable substance and explosive in nature; it cannot be easily transported from one place to another and it can be generated by the hydrolysis of water but it is a very expensive process.

Urm - since that photo hydrogen technology has moved on at a safe pace - If they had used the investment of electric car batteries instead they would be affordable in cars now! Filling up at a pump like petrol or diesel - & please tell me how they are disposed of a motorist on LBC stated he had done 80,000 miles in his & he needed a new battery costing £8 grand electric car batteries are poor substitute of an answer environmentally - the cost of renewing one when it's used up - the disposal of a Battery which is bad for the environment - Also where is all the demand when up & running how is this extra electric going to be produced ? When we can barely serve the national grid for normal use now ?
Plus where is the electricity demand being produced helping the environmental issues of disposal - a German firm have developed a good hydrogen car - yet all the investment is going into electric car production which is self-interest IMO for the big corporations who have gone down a self-interest wrong track - 2–3 hours to charge up not enough working electric charging pumps-just not feasible!

An easy serviceable engine - in fact very little maintenance needed - Totally reliable - easy to fill up just like petrol etc - Electric is a moneymaker - end off. Farcical idea - the Sinclair motor scooter was laughed at many years back - yet now they think they can produce efficient cars that take hours to charge if you can find a charger ...... If you say oh at home - how about many people who live in high storage flats?

Its not for the average working man, It's for the rich .....

I'm a keen skier and I've been going up to Scotland the past few years. My partner isn't, so I'll do a day or two but the rest of the holiday I'll be sightseeing and walking with her. I keep my eye on the weather a lot, and the diagram you've posted is the norm now. I know you're never guaranteed good skiing in Scotland (and that's why I take my bike and have hill walking as plan B), but even by Scottish standards the past three years have been very poor. You might get the odd week (like this week) where temps plummet and you get a bit of snow, but as there's so much heat in the oceans now a lot of the snow will disappear overnight when one of the warm fronts comes through.

The average person won't have a clue (and why would they?), but if they're seeing a few weeks every winter where we get almost record cold temps you can see why they'd be sceptical about climate change.

I don’t particularly like going off anecdotal evidence but 30 odd years ago, but where I lived, frosts would usually last all day. The pond next to us would freeze over most winters. Doesn’t happen any where near as regular now. I know the internet academics will tell us this is due to natural weather changes and fluctuations and we don’t really need to do anything but no idea how theyre coming to that conclusion with such certainty. Even worse, they don’t consider the very real possibility that they could be wrong.

If myself and the vast majority of the scientific community are wrong and climate change isn’t man made then I don’t particularly see that there has been much harm caused in the long run. If they’re wrong and we just carry on as normal then it is catastrophic.

Total bloaters.
