Dear MEL Topic Readers,
This year set to be first to breach 1.5C global warming limit
2023 was the hottest year on record, about 1.48C warmer than pre-industrial times, the benchmark period of 1850-1900, the time before human-caused emissions of greenhouse gases significantly impacted global temperatures. The first 10 months of this year have been even hotter, and this calendar year is going to be 1.55C warmer than the benchmark. The warmer climate of this year is partly due to natural factors like the El Niño weather pattern, which raises sea surface temperatures over the tropical Pacific Ocean. World leaders pledged to limit long-term temperature rises to 1.5C at the 2015 United Nations Climate Change Conference (COP21). Only less than a decade later, the goal was breached. Even though La Niña, cooler sea surface temperatures over the Pacific Ocean is expected to be developing now, it is uncertain how much it will impact the temperatures next year. China, the USA, and India are the top three greenhouse gas emitters, and combined, they represent nearly 40% of the world population and produce about half of global gas emissions. Their initiatives and actions to reduce greenhouse gas emissions are essential to curb global warming.
