increase in the probability of compound events, such as an increase in concurrent heatwaves and droughts  . There is medium confidence that weather conditions that promote wildfires  have become more probable in southern Europe, northern Eurasia, the USA and Australia over the last century . Furthermore, food security and livelihoods are being affected by short-term food shortages caused by climate extremes  which have affected the productivity of all agricultural and fishery sectors . The frequency of sudden food production losses has increased since at least mid-20th century on land and sea . Droughts, floods and marine heatwaves contribute to reduced food availability and increased food prices, threatening food security, nutrition and livelihoods of millions . Changes in sea surface temperatures drive simultaneous variation in climate extremes, increasing the risk of multi- breadbasket failures . Droughts induced by the 2015-2016 El Niño, partially attributable to human influences , caused acute food insecurity in various regions, including eastern and southern Africa and the dry corridor of Central America . Human-induced climate change warming also worsened the 2007 drought in southern Africa, causing food shortages, price spikes and acute food insecurity in Lesotho . In the fisheries and aquaculture sector, marine heatwaves are estimated to have doubled in frequency between 1982 and 2016, as well as increasing in intensity and length, with consequences for fish mortality . In the northeast Pacific, a recent 5-year warm period impacted the migration, distribution and abundance of key fish resources . At 1ºC warming, the number of people affected by six categories of extreme events was found to have already increased by a factor of 2.3 relative to pre-industrial .
