Important climate question

Hey, I'm so science weather expert, but I was wondering something. Is it a good thing or a bad thing when the temperature goals that scientists are trying to achieve with the recent round of climate talks in Copenhagen are still filled with scenarios like this:

2C – The temperature limit the scientists want

The heatwaves seen in Europe during 2003, which killed tens of thousands of people, will come back every year with a 2C global average temperature rise. Southern England will regularly see temperatures around 40C in summer. The Amazon turns into desert and grasslands, while increasing CO2 levels in the atmosphere make the world's oceans too acidic for remaining coral reefs and thousands of other marine lifeforms. More than 60 million people, mainly in Africa, would be exposed to higher rates of malaria. Agricultural yields around the world will drop and half a billion people will be at greater risk of starvation. The West Antarctic ice sheet collapses, the Greenland ice sheet melts and the world's sea level begins to rise by seven metres over the next few hundred years. Glaciers all over the world will recede, reducing the fresh water supply for major cities including Los Angeles. Coastal flooding affects more than 10 million extra people. A third of the world's species will become extinct as the 2C rise changes their habitats too quickly for them to adapt.

Might I remind you that it's this 2C temperature rise that our own government and most every other government on earth is dramatically failing to meet or even take any kind of real action on. No, it's more and more likely that we'll see 3C or even 4C temperature rises over the next few decades. What do those scenarios look like?

4C - Possible with an extremely weak deal

You mistakenly leave your hermetically sealed climate bunker with your family in some fit of malnutrition induced insanity. The sun instantaneously cooks the brain of your wife inside her skull, lobotomizing her. As you look up to the sky and plead for mercy from a God that either never existed or has long since stopped caring about humanity, your eyeballs char and explode as your children are swept away by the unruly tide that laps at the edge of your oceanfront property in Green Bay, Wisconsin. As you hear their cries and erratically attempt to grope for their flailing limbs, you start to think that maybe you shouldn't have placed so much faith in the scientific integrity of oil companies.

Man, you don't even want to see the 5C scenarios. Suffice to say "Mesquite smoked humans" become the only remaining race and the scuba industry is the world's most dominant economic force.

But I hope you're prepared for that eventuality, because even phrases like "half a billion people will be at greater risk of starvation", predictions of persistent coastal flooding, dramatically increased malaria rates, and the extinction of 1/3 of all species can't even persuade leaders to act. So start using BBQ sauce as a sunscreen, invest heavily in scuba manufacturing and you'll be sitting pretty for the future. It's really the only option.
