A surge of heat spikes has struck land in the last 15 years, despite an overall plateau of global surface temperatures in the same period.
Researchers are still deciphering the reasons for Earth’s warming hiatus (SN Online: 2/9/14). But the boost in high terrestrial temperatures attests to continuing climate change, scientists argue in the March Nature Climate Change.
In an analysis led by climate scientist Sonia Seneviratne of ETH Zürich, researchers combed through global weather records over the last 30 years. The team assessed the area of land experiencing peak highs, defined as days above the 90th percentile of a region’s typical temperature range over the three decades.
