We can emit 565 gigatons of CO2 to stay below the 2 degrees Celsius limit that would result in catastrophic climate change. We have 2795 gigatons of CO2 worth of fossil fuels in known reserves. That's 5 times more than we can afford to burn. So why are we still allowing the exploration for oil? We need to invest in renewables and stop supporting fossil fuel industries. Otherwise, future generations will pay the price for our greed.
