warming are understood and modeled fairly accurately.
Global
warming causes ocean temperatures to rise, resulting in an increased loss
of oxygen, which can then affect the nitrogen budget across the

You might expect to see heat waves on the list — even though climate and weather are two different (but related) phenomena — but the report is a good reminder
of the tremendous scope
of problems a
warming globe can
cause; it's not just about an extra couple degrees and wearing fewer sweaters: «With
warming temperatures, the breeding cycle
of malaria - carrying mosquitoes is shortening, which means more mosquitoes — and malaria — each year.»

of Water and Atmospheric Research, the

of malting barley, which, when combined with the scarcity
of hops right now, stands to have a profound and negative impact on the world's beer supply starting now, and for decades to come.
Climate change refers to a change in the «average weather»
of an area

cause of that.

globe will be some
of the first and hardest hit victims
of climate change: «The poorest people in the world, who have had virtually nothing to do with
causing global
warming, will be high on the list
of victims as climate disruptions intensify.»
The
warming we've had in the last thirty years implies that at best, we could expect 1 °C from a doubling
of CO2, but observations from eight natural experiments around the
globe, and even on Mars and Venus suggest that 0.4 °C is the upper bound
of climate sensitivity to any
cause.
Given the current phase
of global
warming, which is
causing temperatures in the tropical Pacific to rise, the world might see «enhanced ENSO variability — more severe El Niños and La Niñas, and more extreme climate conditions around the
globe,» Li told OurAmazingPlanet.

globe should have been cooling and the level
of TSI could not be the

warming.

caused by
warming poles, leads to a near total shutdown
