3. Human influence on the
climate system is clear.
Continued GHG emissions will
cause further warming and
amplify existing risks.
Changes in climate have
caused impacts in natural
and human systems.
Multiple pathways exist to likely
limit warming to below 2°C.
4. Warming of the climate system
is unequivocal

6. Human influence on the climate system is clear,
and recent anthropogenic emissions of
greenhouse gases are the highest in history.

Any climate target implies
a limited carbon budget
14. Budget for the 2°C target: 790 bill t C
CO2 emissions until 2014*: −545 bill t C
CO2 emissions in 2014*: 10.1 bill t C
Remaining emissions: 245 bill t C

Limiting climate change would require substantial and
sustained reductions in greenhouse gas emissions which,
together with adaptation, can limit climate change risks.

Ocean warming dominates the increase in energy stored in the climate system, accounting for more than 90% of the energy accumulated between 1971 and 2010 (high confidence).
