Hurricane Sandy was a turning point on views about climate change, but the effect doesn’t trump political views.
Despite what some climate advocates think, extreme weather events do little to sway Americans' political views on climate change.

CSIRO's climate science has contributed a number of important, and unexpected, findings.
Changes in ocean temperatures are driving unusual weather patterns across Europe.
Hurricane Pali churns over the eastern Pacific on January 11.

January hurricanes are rare events, but two have already formed this month. Atmospheric scientist Adam Sobel explains the conditions that generated Pali and Alex.
Hurricane Patricia as it made landfall on the Pacific coast of Mexico.
False complacency: Hurricane Patricia didn't devastate Mexico as feared, but provides more evidence that warming waters raise the chances of more intense storms.
Obama made a trip to Alaska to steer the national conversation to the effects of climate change.
Obama's trips to vastly different areas – New Orleans and Alaska – laid bare the rising costs of adapting to climate change, now and in the future.
This summer’s El Niño is likely to bring more frequent heatwaves to a large swathe of Australia’s north and east.
The link between El Niño and heatwaves is complicated. But what we can say is that this summer's strong El Niño conditions are likely to bring more heatwaves to much of Australia's north and east.
Places near the equator, with less natural climate variation, were the first to see humanity’s climate fingerprint.
Global warming is, by definition, experienced worldwide. But a new study shows that the tropics were the first places on earth where the human effect on climate outstripped normal climate variations.
Yes, it’s been cold. But the hot weather just keeps on getting hotter.

Melbourne, Canberra and much of southern Australia have shivered through a cold winter. But on a longer view, record cold snaps are disappearing, while Australian heat records continue to be broken.

The latest science on hurricanes and climate change explained – vital information for coastal regions to prepare for the effects of more intense storms.
Really dry: a Colorado River aqueduct in southern California.
Historical analysis shows that natural forces are behind California’s drought, but global warming has contributed 8%-27% to the drought’s severity.
One more California wildfire from last year: getting more dangerous and more expensive.
The US West – suffering one of the most damaging wildfire seasons this decade – needs to break with current practices to avert more costly and dangerous wildfires in the future.
The large 1982 El Niño contributed to the Ash Wednesday bushfires that killed 75 people in south east Australia.
El Niño has arrived, it's getting stronger, and it's not about to go away soon. And already there are rumblings that this could be a big one.
Levees in New Orleans were unable to prevent flooding during Hurricane Katrina in 2005.
Delta cities in both rich and poor countries face uphill, and potentially costly, battle in containing risk from flooding.
Flooding during Hurricane Sandy devastated New York City’s transportation and power infrastructure.
Study finds higher risk of flooding from a combination of storm surge and heavy precipitation, particularly along the East Coast of the US.
People were talking about heatwaves long before the data proved they were on the rise.

The history of climate change is writ large in literature - and not just scientific journals. An analysis of Google's vast library shows a rise in use of phrases such as "unusual weather" and "heat wave".
Blame El Niño.
Climate change models predict higher chances of severe rain for Texas and other places in the US, but linking climate and extreme weather is still an immature science, says Texas state climatologist.

Regular statistics isn't much good at predicting the improbable.
More like these? Typhoon Haiyan in 2013.
New analysis shows that warmer ocean temperatures in the Pacific are creating more intense typhoons.
It’s hard to know for sure what role climate change played in the intensity of Cyclone Pam.

A causal relationship between cyclone behaviour and anthropogenic global warming is a very real possibility. But most climate scientists hesitate to attribute any single event to global warming.
