Long-term climate variability is the range of temperatures and weather patterns experienced by the Earth over a scale of thousands of years. New research suggests it could fall as the world warms.<\/p>\n

A study using data taken from fossils and ice cores finds that long-term temperature variability decreased four-fold from the Last Glacial Maximum (LGM<\/a>) around 21,000 years ago to the start of the Holocene<\/a> around 11,500 years ago. Within this period, natural processes caused the planet to warm by around 3-8C.<\/p>\n

If future global emissions are not curbed, human-driven global warming could cause further large declines in long-term temperature variability, the lead author tells Carbon Brief, which may have far-reaching effects on the world\u2019s seasons and weather.<\/p>\n

However, it is still unclear how a decline in long-term variability could affect the frequency of extreme weather events, she adds. This is because the chances of an extreme event happening could be influenced by both short- and long-term climate variability, as well as global temperature rise.<\/p>\n

Digging up the past<\/strong><\/p>\n

The new study, published<\/a> in Nature, is the first to make a global assessment of how long-term temperature variability changed from the LGM to the Holocene.<\/p>\n

During the LGM, the world\u2019s last major ice age, snow covered much of Asia, Europe and North America. Yet, within a few thousand years, global temperatures rose by around 3-8C, causing the ice to thaw and the world to enter its current geological period, the Holocene.<\/p>\n

The cause of this temperature rise is still disputed by scientists, but research<\/a> suggests the natural release of large stores of CO2 from the world\u2019s oceans may have played a role.<\/p>\n
