What extreme weather events were related to climate change in 2015?

Click columns to sort by region or whether the event is climate change related.

Region	Location	What happened?	Was it climate change related?	What was the influence of climate change on the event?
Global	The Globe, India and Central Pacific	Record warmth during 2015	Yes	Largely climate change related. Especially for the globe and India. Less clear for the Central Pacific.
North America	United States	More extreme daily rainfall events across the country than normal. These were associated with flash flood events.	Not conclusive	Consistent with climate change trend but not conclusive.
North America	Alaska, US	Second worst fire season since 1940 (by area burnt). Source: AAP Image/NEWZULU/ERIN UNDERBRINK	Yes	Climate change likely increased the severity of fires.
North America	Washington state, US	Low snow amounts led to decreased spring riverflow and increased risk of wildfire.	Not conclusive	Probably related to climate change as the warming trend is associated with reduced snowfall.
North America	Florida, US	High tides caused flooding in Miami Source: B137/Wikimedia CC BY-SA	Yes	Climate change related sea level rise has exacerbated flooding related to high tides.
North America	Eastern US	Record cold winter weather events with associated storms and blizzards.	No	Climate change has reduced the likelihood of cold winters.
North America	North America	Cold February 2015 included storms and blizzards	Not conclusive	Possible contribution to event through effect of reduced Arctic sea ice.
North America	Western Canada	Extreme drought led to increased wildfire risk and water restrictions.	Yes	Warmer conditions are associated with climate change, but the low rainfall probably wasn't.
Europe	UK	Sunniest winter on record	Yes	Climate change has increased the likelihood of very sunny winters.
Europe	Central Europe	Heatwaves with many heat records broken. Increased human heat stress due to these events.	Yes	Climate change has likely increased the chance of heatwaves.
Africa	Nigeria	The wet season onset was delayed leading to crop failures.	No	No evidence of any climate change influence.
Africa	Egypt	Severe heatwave led to human discomfort and linked with excess deaths.	Yes	Climate change increased human discomfort during this event.
Africa	Ethiopia and Southern Africa	Extreme drought led to crop failure and necessitated an international aid effort. Source: AAP Image/ChildFund	Yes	Climate change contributed to lack of rainfall.
Asia	India and Pakistan	Severe heat and humidity associated with excess deaths and hospital admissions. Source: AAP/Syed Rizwan Ali	Yes	Climate change exacerbated these heatwaves.
Asia	Chennai, India	Heavy rains caused flooding with large economic damages. Source: EPA/STR	No	Climate change influence likely cancelled out by cooling effect of aerosols.
Asia	Southeast China	Heavy rains before the wet season caused flooding and deaths in several cities.	Yes	Climate change increased the chance of intense rain events occurring.
Asia	Western China	Record heat associated with heat stress, fatalities and severe agricultural impacts.	Yes	Climate change increased the likelihood of severe heat.
Asia	Japan	Summertime heatwave caused increased incidence of heatstroke.	Yes	Climate change increased the likelihood of severe heat.
Asia	Indonesia	Heat and drought associated with wildfires and deaths through respiratory problems.	Yes	Climate change increased the likelihood of extreme heat and contributed to low rainfall.
Oceania	Australia	Record October heat linked with bushfires and crop losses.	Yes	Climate change increased likelihood of severe heat.
Oceania	Tasmania, Australia	Record low October rainfall caused crop losses and subsequent water shortages for electricity generation.	Yes	Climate change likely increased the chance of low rainfall, albeit only slightly.
Global	Northwest Pacific	Increased tropical cyclone activity	Yes	Climate change increased the likelihood of this event.
Global	Northern Hemisphere	Record low sea ice extent in March 2015 Source: NASA/Kathryn Hansen	Yes	Climate change contributed to the record low sea ice extent.
