NASA and the US National Oceanic and
Atmospheric Administration (NOAA)
have confirmed 2014 was the warmest year
since records began in 1880.
The 10 warmest years in the instrumental record, with
the exception of 1998, have now occurred since 2000.

Prof Jonathan Overpeck, co-director of the University of
Arizona's Institute of the Environment, said in
"Humans are literally cooking their
planet...It just shows that human emissions of greenhouse gases,
mainly from the burning of fossil fuels, are taking over the
Earth's climate system. The data are clear. The Earth is warming
and humans are causing the bulk of this warming."
Overpeck said in the
"Perhaps more important
than the global temperature story are the impacts of record
regional heat. In places like California, the Southwest U.S. more
generally, Australia and parts of Brazil, record heat is
exacerbating drought and leading to more stress on our water
supplies and forests."
"With continued global
warming, we're going to see more and more of these unprecedented
regional conditions, and with them will come more and more costs to
humans and the things they value. 2014 shows that humans are indeed
cooking their planet as they continue to combust fossil
Dr Radley Horton, a scientist from Columbia
University, said in
"What we have known for
decades is that increasing greenhouse gas concentrations - due to
human activities - have stacked the deck dramatically towards more
record warm years, and fewer record cold years."
Prof Stefan Rahmstorf, head of earth system
analysis at the Potsdam Institute for Climate Impact Research in
Germany, said in the
New York Times:
"Obviously, a single
year, even if it is a record, cannot tell us much about climate
trends. However, the fact that the warmest years on record are
2014, 2010 and 2005 clearly indicates that global warming has not
'stopped in 1998', as some like to falsely claim."
Dr Gavin Schmidt, director of Nasa's Goddard
Institute of Space Studies, said in the
New York Times:
"Why do we keep getting
so many record-warm years? It's because the planet is warming. The
basic issue is the long-term trend, and it is not going
