Doha: The climate warnings come at a time when the world is grappling with a severe global food crisis, with projections indicating that nearly 670 million people will continue to face hunger through 2030.
According to Qatar News Agency, climate shocks, the global water crisis, biodiversity loss, and other mounting challenges continue to undermine global food security and push more people into hunger. Extreme heat further exacerbates these risks, intensifying drought, wildfires, and pest outbreaks, while triggering sharp declines in crop yields once critical temperature thresholds are breached.
Last April, the United Nations warned that extreme heat waves are pushing global agrifood systems to the brink of collapse, threatening the livelihoods and health of more than one billion people. The Food and Agriculture Organization of the United Nations (FAO) and the World Meteorological Organization (WMO) said that extreme heat waves have become more frequent, intense, and prolonged, causing damage to crops, livestock, fisheries, and forests. They added that extreme heat is not only redrawing the map of what farmers, fishers, and forestry workers can cultivate and when they can cultivate it, but is also determining, in some cases, whether they can continue working at all.
This, in turn, places global food security before a highly uncertain future and steadily gnaws away at one of humanity's principal areas of strength: its ability to sustain reliable food production. WMO had warned in March that record greenhouse gas concentrations continue to drive land and ocean temperatures toward unprecedented levels. The organization said that this continued rise portends severe long-term consequences for humanity, warning that the Earth's climate has become more out of balance than at any other time in recorded history.
It further confirmed that last year recorded temperatures approximately 1.43 degrees Celsius above the 1850-1900 baseline average, in addition to setting a record for ocean heat. In addition, WMO noted that, as glacier retreat and ice melt continue, ocean warming and land ice melt are contributing to the long-term rise in global mean sea level. It described these findings as a powerful impetus for intensifying efforts to provide life-saving forecasts and early warning systems to those who can protect lives and livelihoods, enabling them to mitigate the devastating impacts of ongoing climate disruptions on the most vulnerable populations.
It has issued annual climate updates for more than three decades, and the record-breaking indicators registered over the past decade have become a growing source of concern. Under the Paris Agreement, which entered into force in November 2016, nearly 200 countries agreed to limit global warming to 1.5 degrees Celsius above pre-industrial levels. Scientists and environmental advocates have repeatedly warned, however, that achieving this target-namely avoiding the worst impacts of climate change-is becoming increasingly unlikely, as the world moves ever closer to a climate trajectory that many experts regard as unalterable without far more ambitious action to curb emissions and accelerate climate adaptation.
