  A special report issued by the IPCC to as global warming of 1.5 °C makes among other things the following central statements to the consequences of a global warming of 1.5 °C in comparison to one of 2 °C:
  
  The risk of triggering tipping points in the Earth's climate system and uncontrollable chain reactions is significantly lower at 1.5 °C of warming. Tipping points in the cryosphere, according to a group of researchers in a 2019 commentary, could already be dangerously close. With warming of 1.5 °C to 2 °C, the Greenland ice sheet or Arctic sea ice could melt. The tipping point for the West Antarctic ice sheet may already have been surpassed, but warming of 1.5 °C would slow the melting process by a factor of ten compared to 2 °C of global warming, making it easier to adapt to a sharply rising sea level. However, the carbon budget of 500 billion tons for a 50 percent chance of reaching the 1.5-degree target may already have been used up.
  
  Compared to the current global warming projections by the Intergovernmental Panel on Climate Change (IPCC), achieving the 1.5-degree target could force 80 percent fewer people to migrate due to climate change, as fewer areas of the Earth would become uninhabitable. According to CAN Europe, aligning Europe with the 1.5-degree target could save one trillion euros by 2030.
