Bla what is your opinion on motorcycles?

The CO₂ emission from motorcycles is comparative to cars, but they emit very high amounts of several other pollutants, such as CO, which is a very unhealthy gas. I think those using conventional fuel engines should be banned.

This isn't manufactured data; this is millions of temperatures taken from thousands of weather stations compiled into averages across time. Also, have you ever told your children that there is a lot less snow now, that is, if you live in a region where a decrease in snow would've been observed (northern Europe, northern US and all of Canada, China, Japan)? Global warming is to blame.

No, we are not going to go back to the old technologies, instead, at least for Arizona, we are (or already have) mov(ing/ed) to solar power, hydroelectric power, and nuclear power. We are moving past gasoline (finally) to electric cars and hydrogen fuel cells.

But most cars still use gasoline, and only a tiny percentage of power is generated from solar and hydroelectric. It would take too long to change. IMO nuclear isn't very safe, one accident and many die.

All countries, such as China, Russia and the EU...not just the USA, would also have to take the SAME steps and have the SAME consequences for doing whatever it would take to make an actual difference. If not, NOTHING is going to happen...nor should it. If it's a real threat to humanity, humanity will respond for self preservation, if not then we will go extinct, which is going to happen anyway.

The (people in) governments are too busy making money to bother unfortunately.

I blame global warming for the 85 degree weather I am experiencing here!!!

Darvince · « **Reply #189 on:** February 25, 2014, 02:16:24 PM »

Tuto, don't blame global warming for that, blame global warming if 30C is reached regularly during February when it didn't used to be.

So basically you are saying "Don't blame global warming for unusually warm weather, but blame global warming for unusually warm weather!" because it shouldn't be 85 degrees at this time of year.

Darvince · « **Reply #192 on:** February 26, 2014, 03:55:42 PM »

NO. Don't blame global warming for one, isolated incident of unusually warm weather. Blame global warming for a pattern of unusually warm weather.

Either way I wasn't being serious. Gawsh

Our thermodynamics lecturer (who also works with climate research and ice core drilling projects in Greenland) gave an example of a a geophysics experiment. We let out greenhouse gases and see what happens to the Arctic ice.
The colored lines are predictions for what would happen to the Arctic ice.

He then showed the data since 1990 (pink). Everyone laughed.

"So instead of disappearing in 2080, the Arctic sea ice might disappear before you've graduated."

The week after he calculated the energy that has been necessary to smelt the approx 8.25 * 10¹⁴ kg of ice per year.
Latent heat of smelting: L = 334 kJ/kg
E = 8.25 * 10¹⁴ kg * 334 kJ/kg = 2.8 * 10¹⁷ kJ

For comparison our global annual energy consumption: 5.2 * 10¹⁷ kJ

tell the kids stories about the artic ice

Darvince · « **Reply #196 on:** February 27, 2014, 04:01:40 PM »

no tell the current toddlers about the arctic sea ice

what the fuck

also TIL danish college students are masochists

well it won't be gone for more than a few days... for a few years...

blotz · « **Reply #198 on:** February 27, 2014, 05:05:06 PM »

an year ago, that would have included for a few decades... and a decade ago it would have included for a centry or two

atomic7732 · « **Reply #199 on:** February 27, 2014, 07:03:29 PM »

I'm saying for the first few years it'll only be completely gone for a short amount of time

in fact some random year it might not fully melt

but dang

If I speak my opinion, I will be persecuted. All I can say us that global warming is just a sad, sad fault of humanity among thousands upon thousands of other faults of humanity.

Xriqxa, if I can share my opinions on here, you're more than welcome to speak out. (err, type out, lol)
This is a forum. Express yourself... as long as you are not a jerk.

Darvince · « **Reply #202 on:** April 15, 2014, 04:00:36 PM »

Just because this topic is rather sciency and people have made bad arguments against the fact of global warming in this topic, doesn't mean you're not welcome to say your opinion.

Xriqxa · « **Reply #203 on:** April 16, 2014, 07:26:37 AM »

It's not that, I was referring to humanity in general. It's like you just speak your opinion in a public area, and SAY it's just your opinion, and before you know it everyone's all over you like you are the only non-zombie in the area.

blotz · « **Reply #204 on:** April 16, 2014, 11:42:14 AM »

just share the thoughts

Xriqxa · « **Reply #205 on:** April 16, 2014, 08:31:14 PM »

I feel it's a mix of both humanity and nature. Cows fart, we pollute. There are other factors as well, but I'm too lazy to think of them.

Darvince · « **Reply #206 on:** April 16, 2014, 08:37:15 PM »

Nature still emits more greenhouse gases than humanity. However, the world was used to how much nature was producing. Now, we have increased the amount of greenhouse gases emitted by nearly 50%, causing a massive imbalance until plants and the ocean absorb more than is being produced.
