(CN) As climate change receives more attention across the globe, it’s crucial that scientists and researchers have the most accurate data possible on global temperatures. Researchers out of China’s Sun Yat-Sen University released Thursday a newly merged global surface temperature dataset to assist in climate research.
Part of the difficulty in creating an accurate picture is the lack of observational data in some regions such as the Arctic or high-altitude areas like the Qinghai-Tibetan plateau, making it difficult to assess temperature variations adequately and consistently across the globe.

Earth is warming rapidly, but there is too little observational data in some regions such as the Arctic or high-altitude areas like the Qinghai-Tibetan plateau to adequately and consistently assess temperature variations across the globe. To better understand how temperatures have increased, an international team led by researchers at Sun Yat-Sen University in China has released a newly merged global surface temperature dataset, including reconstructed land and marine measurements from the 1850s to 2018. The study provides evidence that there was a consistent increased warming trend compared with previous estimations, which closely matches the available observational data and updated simulations covering the past two decades.
