Transcript At international climate talks, world leaders are trying to keep the world to 1.5 degrees Celsius of warming. A recurring fever is a fever that happens multiple times over a period of time. A recurrent fever is one that comes back in a pattern. To try to keep global warming to 1.5C in the long term, the world will have to reduce CO2 emissions by 45% by 2030, with respect to 2010, and reach zero net emissions (carbon neutrality) by 2050. The preindustrial level of CO2 was about 280 parts per million (ppm), so double is roughly 560 ppm. Many climate scientistsmyself includedthink that a single decade is too brief to accurately measure global warming and that the IPCC was unduly influenced by this one, short-term number. We've already taken care of that by pumping a century's worth of pollution into the atmosphere. Kliegman RM, et al. Changes in the timing of peak flows in rivers and streams are reducing water supplies and worsening competing demands for water. Call your baby's health care provider if your child is: There's probably no cause for alarm if your child has a fever but is responsive.
