Earth's water cycle is being thrown off balance, bringing dangerous swings between floods and drought, according to the World Meteorological Organization.

The WMO warns that climate change is disrupting Earth’s water cycle, causing shrinking rivers, groundwater shortages, glacier loss, floods and droughts that threaten communities worldwide.

Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds ...

As an essential material for the survival and reproduction of almost all aerobic organisms, oxygen is closely related to the formation and development of complex organisms. A recent review provides a ...

Earth is closer to the sun at some times of year than at others, with the time of closest approach shifting over a period of 22,000 years. This affects Earth's climate, including ice ages, but a team ...

Newswise — HOUSTON – (Nov. 14, 2023) – As the primary element of life on our planet, carbon is constantly journeying from living creatures down into the Earth’s crust and back up into the atmosphere, ...

Explore how studying sediment layers in ancient lakebeds reveals Earth’s deep-time climate cycles and the lasting 405,000-year climate cycle. Ribbons of blue — the modern Raritan and Neshanic rivers — ...

Scientists at the University of Southampton have uncovered evidence from ancient rocks that Earth's climate continued to fluctuate during its most extreme ice age—known as Snowball Earth. During the ...

Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet's higher latitudes. For the past million years, these ...
