Megadrought affects gravity waves
A severe drought that has lasted on Earth for over two decades is now thought to have affected gravity waves where our planet’s atmosphere meets outer space.

Some say delegates at the COP27 summit missed a key opportunity to recognize the connection between the twin nature and climate crises.
The Earth’s climate has experienced some big changes. A new study shows that the planet has a “stabilizing feedback” mechanism that acts over hundreds of thousands of years to keep global temperatures within a steady habitable range.
According to a study by the World Meteorological Organization, atmospheric levels of all three greenhouse gases have hit record highs.
A new study has produced globally complete maps of the carbon-driven warming that occurred in the Paleocene Eocene Thermal Maximum (PETM), 56 million years ago. Changes in rainfall patterns and amplification of warming at the poles were remarkably consistent with modern trends.
The Atlantic meridional overturning circulation (AMOC), an ocean current system that carries warm water from the tropics into the North Atlantic and transports cold water from the northern to the southern hemisphere, is an important mechanism for the regulation of Earth’s climate.
New research shows forest fires are burning twice as much global tree cover as 20 years ago due to climate change. Resulting in blazes claiming an estimated three more million hectares each year – an area the size of Belgium – compared with 2001.
Forests around the Earth are transforming at a shocking rate due to climate change, with trees advancing into previously barren tundra in the north while perishing from excessive heat farther south, scientists have found.
It is apparent that more climate extremes are occurring. Earlier snowmelts in high-altitude regions, severe forest fires and rain pulses followed by dry periods are becoming the norm.
Human activities such as marsh draining for agriculture and logging are increasingly consuming saltwater and freshwater wetlands. These important areas cover only 1% of Earth’s surface but store more than 20% of all the climate warming carbon dioxide absorbed by ecosystems worldwide.
