Weather of 2012

The year began with La Niña conditions, meaning cooler than normal waters in the eastern Pacific Ocean near the equator. By later in the year, the global weather pattern shifted to more neutral conditions. The global temperature was {{convert|1.03|°F|°C|abbr=on}} above average, making it the tenth-warmest year ever recorded.{{cite report|title=2012—Third Warmest La Niña Year on Record|publisher=Climate.gov|author=Susan Osborne AND Jessica Blunden|date=January 15, 2013|accessdate=June 30, 2023|url=https://www.climate.gov/news-features/featured-images/2012%E2%80%94third-warmest-la-ni%C3%B1a-year-record}}

Throughout 2012, there were 9,655 people killed by natural disasters, which marked the fewest global fatalities in a decade. This included 3,574 deaths related to hydrological events. The lower than usual death toll was due to fewer flooding and cyclonic events. Asia was the continent most often affected during the year.

The following listed different types of special weather conditions worldwide.

In January, cold temperatures of {{convert|-30|C|F|abbr=on}} killed 112 people in Ukraine, while avalanches and a cold wave killed 45 people across Afghanistan.{{cite report|title=Afghanistan Humanitarian Bulletin Issue 01|work=United Nations Office for the Coordination of Humanitarian Affairs|date=January 31, 2012|accessdate=June 30, 2023|url=https://reliefweb.int/report/afghanistan/afghanistan-humanitarian-bulletin-issue-01-01-31-january-2012}}

Drought conditions persisted across much of North America throughout the year, causing at least US$39.9 billion in damage, much of it from crop failures. A strong heat wave during the summer killed 129 people.

Elsewhere, drought conditions in northeast Brazil led to their government allocating R$2.7 billion (US$1.35 billion) worth of assistance for farmers and water distribution.{{cite report|date=May 14, 2012|title=REDLAC Weekly Note on Emergencies Latin America & the Caribbean – Year 5 – Volume 257|accessdate=July 3, 2023|publisher=Office for the Coordination of Humanitarian Affairs|at=ReliefWeb|url=https://reliefweb.int/report/brazil/redlac-weekly-note-emergencies-latin-america-caribbean-year-5-%E2%80%93-volume-257}}
