A) That's 10-20°C, not °F. We're already seeing temperatures of 120°F (49°C) in parts of the world, so another +20°C puts that at 156°F (69°C). I'm not exaggera

A) That's 10-20°C, not °F. We're already seeing temperatures of 120°F (49°C) in parts of the world, so another +20°C puts that at 156°F (69°C). I'm not exaggerating all that much. B) The projections keep getting more pessimistic as more data is accumulated.
