Can we really limit global warming to “well below” two degrees centigrade? Yes, but only in a model. We have essentially emitted too much carbon dioxide already, and the most feasible pathways to stay “well below” two degrees all require removing carbon dioxide from the atmosphere at an unprecedented scale.
Why you should train your sense of smell Mette Bratt researches the strengthening of the sense of smell. She is now working with test persons who have normal senses of smell. You might consider this ― you might not be capable of judging your own sensitivity to odours.
