Global warming increases the moisture holding capacity of the atmosphere and consequently the potential risks of extreme rainfall. Here we show that maximum hourly summer rainfall intensity has increased by about 11.2% on average, using continuous hourly gauge records for 1971-2013 from 721 weather stations in China. The corresponding event accumulated precipitation has on average increased by ...

In a changing climate arising from anthropogenic global warming, the nature of extreme climatic events is changing over time. Existing analytical stationary-based risk methods, however, assume multi-dimensional extreme climate phenomena will not significantly vary over time. To strengthen the reliability of infrastructure designs and the management of water systems in the changing environment, ...

Earth's ecosystem has been active for millions of years without particular problems and may lead the development of variety of animal species around the world.

The Okhotsk Sea is the southernmost marginal sea that is ice-covered during winter; therefore, it is considered to be an area having sensitive environmental characteristics due to the influence of global warming. In order to detect such environmental changes, monitoring of oceanographic conditions is considered important. However, few monitoring studies have been made in the offshore area of th...

Natural unforced variability in global mean surface air temperature (GMST) can mask or exaggerate human-caused global warming, and thus a complete understanding of this variability is highly desirable. Significant progress has been made in elucidating the magnitude and physical origins of present-day unforced GMST variability, but it has remained unclear how such variability may change as the c...
