According to new research it's estimated that global carbon emissions will reach 40 billion tons 2014, a record high in human history. If carbon-dioxide in the atmosphere exceeds 3200 tons then the global temperature average will see a 2 degrees Celsius increase since the Industrial Revolution. The Earth hasn't actually seen any mind-blowing drastic changes in the environment because of climate change but this 2 degree threshold is where things start to change and it might actually be a big threat. carbon-dioxide in the air increases every year not at a linear rate but an exponential one. There's already ~2000 tons of carbon dioxide in the atmosphere and its estimated that another 1200 tons will be emitted in the next 30 years. That's our generation.
What can we do to prevent the rise in the global temperature average, and what is already set in stone?
