18 hours ago · This study presents a comprehensive analysis on the variations in the tropical cyclone (TC) frequencies during 1980–2021, including the linear trends, periodicities, and their variabilities on both global and basin-wise scales. An increasing trend in the annual number of global TCs is identified, with a significant rising trend in the numbers of tropical storms (maximum sustained wind ) and ...
18 hours ago · The data is stark: More than 80 percent of global AI funding goes to U.S. or Chinese firms compared with just 7 percent to EU businesses. The gap is similarly striking for quantum computing.
Sep 4, 2024 · These variations with intensity show that, in general, global warming increases TC intensity across both the CRH and SD results, although in the CRH results, frequency increases more for more intense storms, while in the SD results, frequency decreases less for the more intense storms.
Sep 3, 2024 · The overall reduction in activity is not unheard of as tropical weather experts, including Klotzbach, have long suggested that overall global tropical cyclone activity is on the decline worldwide, especially in the Western Pacific.
18 hours ago · In comparison, forested areas decreased by an average of −2.19 km 2 per year, resulting in an average annual decline of −3171 tC in forest carbon stocks due to urbanization. The fluctuation in carbon stocks across the urban forests of the ten cities ranged from −68 % to 48 % over 15 years, primarily influenced by the extent of preserved forest area, with forest composition playing a ...
2 days ago · According to Zhang, the COVID-19 pandemic and subsequent economic shocks led to a drop in HDI in 2020 and 2021. The decline was a first in the history of the index. While some HDI indicators are rebounding, Zhang continues to see troubling signs for human progress. “Despite this recovery, the human development path has shifted downwards ...
Sep 10, 2024 · CFSR, GLDAS, CRAL, and HMASR are good in simulating the spatial pattern of climatological SCF, with lower bias and higher correlation and Taylor skill score (SS). By contrast, ERA5L, JRA55, and ERA5 have a relatively good performance in terms of SCF annual trends among eight reanalysis datasets.
