A team of researchers has found that black-browed albatrosses living on the Falkland Islands see rising divorce rates during times when the sea surface temperatures rise. They point out that hunger could lead to one or the other partner abandoning an egg or hatchling—events that could lead to one of the birds ditching the other.

Medvedev used an inhaler during a second-set changeover Wednesday while being looked at by a doctor, who checked his breathing with a stethoscope.

Russian planes seeded clouds to bring down rain on huge wildfires raging in the Siberian region of Yakutia that in one place spread dangerously close to a hydroelectric power plant, authorities said on Monday.

Ben Rich looks back at a month in which an air frost has been seen somewhere in the UK every single morning. In fact, provisional data from the Met Office suggests it has been the frostiest April for at least 60 years - with the lowest average minimum temperatures since 1922.

Rising temperatures and dwindling oxygen levels are decimating marine species. But humanity can avert mass die-offs by curbing fossil fuel use and other planet-warming activities.

Gardeners in Alaska know that it’s hard to grow big, juicy tomatoes here. But as the climate rapidly warms in the far North, that could change. Anchorage reached 90 degrees Fahrenheit (32 degrees Celsius) for the first time on record in 2019.

Widespread mortality of Pacific salmon Oncorhynchus spp. returning to spawn in Alaska coincided with record-breaking air temperatures and prolonged drought in summer 2019.

Dog owners in the sunniest state need to know the correct measures to take to keep pets safe during the summer.

State and federal agencies are working to combat what experts call one of the harshest and most neglected effects of climate change in the U.S.: rising worker heat deaths and injuries.

A heat warning has been issued for Ottawa and the surrounding region.

As the Arctic continues to warm faster than the rest of the planet, evidence mounts that the region is experiencing unprecedented environmental change. The hydrological cycle is projected to intensify throughout the twenty-first century, with increased evaporation from expanding open water areas and more precipitation. The latest projections from the sixth phase of the Coupled Model Intercomparison Project (CMIP6) point to more rapid Arctic warming and sea-ice loss by the year 2100 than in previous projections, and consequently, larger and faster changes in the hydrological cycle. Arctic precipitation (rainfall) increases more rapidly in CMIP6 than in CMIP5 due to greater global warming and poleward moisture transport, greater Arctic amplification and sea-ice loss and increased sensitivity of precipitation to Arctic warming. The transition from a snow- to rain-dominated Arctic in the summer and autumn is projected to occur decades earlier and at a lower level of global warming, potentially under 1.5 °C, with profound climatic, ecosystem and socio-economic impacts. The Arctic warms faster than other areas of the planet, which also influences precipitation. Here, the authors show that the latest CMIP6 model ensemble shows a faster Arctic warming and sea-ice loss, causing an earlier transition from a snow- to a rain-dominated Arctic than previously thought.

An assessment by geotechnical experts will need to be completed in order to know the stability of the slide and understand continuing risk.

An evacuation alert has been issued by Yukon Emergency Measures Organization for areas of Tagish, Marsh Lake and Lewes River Road. This alert is due to high water and flooding in the areas. Water levels have exceeded what they were in the 2007 flood.

As grape harvest time nears across Greece, winemakers are worried about the impact on output from a succession of extreme weather events.

Two resolutions brought before the Alaska Federation of Natives during this year’s annual convention called for efforts to reduce salmon bycatch for fish that return to the Yukon and Kuskokwim rivers.

There is danger lurking on the floor of the Bering and Chukchi seas for mussels, snails, clams, worms and other cold-water invertebrates, according to a new study led by National Oceanic and Atmospheric Administration scientists.

Because the heat coincided with the summer solstice, when the northern hemisphere gets “maximum energy” from the sun, "it was really kind of a one-two punch.”

Cecelia Brooks remembers a time when the deep forest of New Brunswick was so cold, snow could still be found in its depths in August. That rarely happens anymore. Brooks, who lives on St. Mary's First Nation in Fredericton, is one of many Indigenous people in the Wabanaki region who say climate change is threatening traditional plants and medicines. Those changes, Brooks says, could alter their way of life.

"Even ordinary rainfall can be regarded as an extreme event in polar regions," Dou said. This is because rain-on-snow events, which occur when rain falls onto an existing snowpack and freezes into an ice crust, impact wildlife, infrastructure and local communities.
