The planet keeps getting hotter, new data showed this
week. Especially in America, where 2012 was
the warmest year ever recorded, by far. Every few years, the U.S. federal
government engages hundreds of experts to assess the impacts of climate change,
now and in the future.
From agriculture (pictured) to infrastructure to how humans consume energy,
the National Climate Assessment Development Advisory Committee spotlights how a
warming world may bring widespread disruption
Farmers will see declines in some crops, while others will reap increased
yields.working together we can stop global warming by using less harmfull gases

EFFECTS ON WEATHER
An increase in the amount of precipitation. Although
rainfall overall will increase there are some parts of the world that are
already receiving less rainfall and this trend is likely to continue.
Hurricanes and storms will become more frequent, widespread and severe,
in the last 30 years the proportion of category 4 and 5 hurricanes has almost
doubled. Once exclusively confined to the northern hemisphere there have
recently been hurricanes in the southern hemisphere, most notably in Brazil.
DESERTIFICATION
Shifting weather patterns mean some areas receive
less rainfall; the ground becomes barren and unable to sustain crops. In many
parts of the world the layer of topsoil is both very thin and very poor. The
dry, dusty soil is readily blown away and the area becomes desert. African and
Asian countries are particularly hard hit.
