UN climate talks - Last chance to tackle climate change?

If global warming increases average temperature on our planet by more than 2C there is a great chance that this will make our climate totally unpredictable with much more frequent extreme weather events such as floods, drought, and hurricanes.

It is more than obvious that world is still lacking a strong global political will needed to tackle climate change. This is the main reason why there are so few optimists ahead of this year's climate talks in Cancun as many analysts expect yet another failure, and yet another outcome similar to last year's Copenhagen.

The solution to tackling climate change seems rather simple, namely significantly reducing carbon emissions on global level but sadly this is anything but easy.

World still heavily relies on fossil fuels such as coal and oil, and renewable energy sector, despite decent growth in the last couple of years is still nowhere near being able to replace fossil fuels and satisfy a large share of global energy demand.

The transition from fossil fuels to renewable energy will no doubt take some time, and time is currently the luxury we do not have at our disposal. If the world fails to do anything about climate change this will likely put world on track for warming of 7C by 2100.

Politicians still do not take climate change seriously despite saying otherwise. It's like they are waiting for the worst to happen before they decide to act, and this is definitely the wrong tactic for climate change.

Since politicians care so little about environment they should be at least caring for economy, and it has been calculated that just the costs of protecting low-lying and coastal areas from the sea level rise could reach $270 billion a year by 2100.

Poor countries, as always, will suffer the most, because they will find it impossible to adapt to climate change without the help of developed world. And the developed world will likely have enough of its own problems to worry about other countries. In other words, one huge, huge mess.

Lets clean this mess before it is too late.
