Global
The Globe, India and Central PacificRecord warmth during 2015YesLargely climate change related. Especially for the globe and India. Less clear for the Central Pacific.
North America
United StatesMore extreme daily rainfall events across the country than normal. These were associated with flash flood events.Not conclusiveConsistent with climate change trend but not conclusive.
North America
Alaska, USSecond worst fire season since 1940 (by area burnt).

YesClimate change likely increased the severity of fires.
North America
Washington state, USLow snow amounts led to decreased spring riverflow and increased risk of wildfire.Not conclusiveProbably related to climate change as the warming trend is associated with reduced snowfall.
North America
Florida, USHigh tides caused flooding in Miami

YesClimate change related sea level rise has exacerbated flooding related to high tides.
North America
Eastern USRecord cold winter weather events with associated storms and blizzards.NoClimate change has reduced the likelihood of cold winters.
North America
North AmericaCold February 2015 included storms and blizzardsNot conclusivePossible contribution to event through effect of reduced Arctic sea ice.
North America
Western CanadaExtreme drought led to increased wildfire risk and water restrictions.YesWarmer conditions are associated with climate change, but the low rainfall probably wasn't.
Europe
UKSunniest winter on recordYesClimate change has increased the likelihood of very sunny winters.
Europe
Central EuropeHeatwaves with many heat records broken. Increased human heat stress due to these events.YesClimate change has likely increased the chance of heatwaves.
Africa
NigeriaThe wet season onset was delayed leading to crop failures.NoNo evidence of any climate change influence.
Africa
EgyptSevere heatwave led to human discomfort and linked with excess deaths.YesClimate change increased human discomfort during this event.
Africa
Ethiopia and Southern AfricaExtreme drought led to crop failure and necessitated an international aid effort.

NoClimate change influence likely cancelled out by cooling effect of aerosols.
Asia
Southeast ChinaHeavy rains before the wet season caused flooding and deaths in several cities.YesClimate change increased the chance of intense rain events occurring.
Asia
Western ChinaRecord heat associated with heat stress, fatalities and severe agricultural impacts.YesClimate change increased the likelihood of severe heat.
Asia
JapanSummertime heatwave caused increased incidence of heatstroke.YesClimate change increased the likelihood of severe heat.
Asia
IndonesiaHeat and drought associated with wildfires and deaths through respiratory problems.YesClimate change increased the likelihood of extreme heat and contributed to low rainfall.
Oceania
AustraliaRecord October heat linked with bushfires and crop losses.YesClimate change increased likelihood of severe heat.
Oceania
Tasmania, AustraliaRecord low October rainfall caused crop losses and subsequent water shortages for electricity generation.YesClimate change likely increased the chance of low rainfall, albeit only slightly.
