The eastern Arctic Ocean's winter ice grew less than half as much as normal during the past decade, due to the growing influence of heat from the ocean's interior, researchers have found.

By creating conditions akin to the center of Earth inside a laboratory chamber, researchers have improved the estimate of the age of our planet's solid inner core, putting it at 1 billion to 1.3 billion years old.

In a first-ever study using ozone data from commercial aircraft, researchers found that levels of the pollutant in the lowest part of Earth's atmosphere have increased across the Northern Hemisphere over the past 20 years. That's even as tighter controls on emissions of ozone precursors have lowered ground-level ozone in some places, including North America and Europe.

How do different bird species respond to extreme weather events that occur for different amounts of time, ranging from weekly events like heat waves to seasonal events like drought? And how do traits unique to different species -- for example, how far they migrate or how commonly they occur -- predict their vulnerability to extreme weather?

Researchers modeled the effects of rising sea levels along the California coast. While results varied with local topography, the study indicates an increased threat to populated areas already at risk from rising water tables, and the possibility of flooding in unexpected inland areas.

In a new study links the end of the Green Sahara with a previously unknown megadrought which caused mass population shifts in Southeast Asia during the mid-Holocene period.

Even in earlier warm periods there were pulse-like releases of CO2 to the atmosphere. Today's anthropogenic CO2 rise, however, is more than six times larger and almost ten times faster than previous jumps in the CO2 concentration.

Using Greenland ice cores, new research is the first to confirm the longstanding assumption that climate changes between the tropics and the Arctic were synchronized during the last glacial period.

The Greenland Ice Sheet recorded a new record loss of mass in 2019. This was the finding of a team of international researchers after evaluating data from satellite observations and modelling data.

Researchers have identified a global tendency for future sea levels to become more variable as oceans warm this century due to increasing greenhouse gas emissions.

Nitrogen dioxide, which comes from transportation, was half of what would be expected over China in February 2020. Other emissions and cloud properties, however, showed no significant changes.

Scientists studying leaves from a 23-million-year-old forest have for the first time linked high levels of atmospheric carbon dioxide with increased plant growth, and the hot climate off the time.

Rising temperatures due to our greenhouse gas emissions can cause greater damages to our economies than previous research suggested, a new study shows.

Researchers have found their previous discovery of bacteria living on air in Antarctica is likely a process that occurs globally, further supporting the potential existence of microbial life on alien planets.

With the number of extreme weather days rising around the globe in recent years due to global warming, it is no surprise that there has been an upward trend in hospital visits and admissions for injuries caused by high heat over the last several years. But cold temperatures are responsible for almost all temperature-related deaths, according to a new study.

When stony corals have their renowned mass spawning events, in sync with the moon's cycle, colonies simultaneously release an underwater 'cloud' of sperm and eggs for fertilization. But how do the sperm and eggs survive several hours as plankton, given threats from predators, microbes and stresses such as warming waters? A team has discovered some surprising features in coral sperm and eggs (collectively called gametes).

Using high-resolution data, researchers have created the first map of the causes of change in global mangrove habitats between 2000 and 2016 - a valuable tool to aid conservation efforts for these vital coastline defenders.

The 'Cold Tube' can offer relief from the summer heat without relying on air conditioning. It uses half the energy of conventional air conditioners and can be used outdoors or indoors.

Researchers have projected the effects current and estimated future global temperature increases would have on the precise territories that were home to particular primate species, based on projected emissions of CO2.

Organisms need to work together to adapt to climate change, especially in the presence of competitors, suggests a new study.
