During that same period,
average annual rainfall in New South Wales declined by 3.6 inches (92 millimeters).3 Scientists think the decline in autumn rainfall in southeast Australia since the late 1950s may be partly due to
increases in heat - trapping gases in Earth's atmosphere.3, 14 Major bushfires over southeast Australia are linked to the positive phase of an ocean cycle called the «Indian Ocean Dipole» — when sea surface
temperatures are warmer than
average in the western Indian Ocean, likely in response to
global warming.15, 16
«The results show that the extreme sea levels observed
during Hurricane Katrina will become ten times more likely if
average global temperatures increase by 2 °C», said Dr Jevrejeva.
Despite these reclassifications, the general conclusions are similar from previous work: (1)
global temperature anomalies for each phase (El Niño, La Niña, and neutral) have been
increasing over time and (2) on
average,
global temperatures during El Niño years are higher than neutral years, which in turn, are higher than La Niña years.
