January’s heatwave could have killed 374 Victorians. The alarming findings have just been made public by Victoria’s Chief Health Officer Dr John Carnie, who investigated the health effects of the extreme heatwave that ran from 26 January to 1 February. [News Source]

Heatwave blamed for deaths rise. Just over 370 Victorian deaths were probably attributable to the state's heatwave in late January, health authorities say. [News Source]

Heatwave killed 347 people in one week. Health authorities have revealed that the week-long heatwave in late January may have killed at least 374 Victorians, more than twice the death toll from the Black Saturday fires. [News Source]

Arctic ice more vulnerable than ever. The Arctic ocean area covered by ice is one of the lowest ever measured by satellites, and a record high fraction of that area is capped by thin, first-year ice that’s more prone to melt than older, thicker ice is. [News Source]

Satellite data shows Arctic on thinner ice. Arctic sea ice, a key component of Earth's natural thermostat, has thinned sharply in recent years with the northern polar ice cap shrinking steadily in surface area, government scientists said on Monday. [News Source]

Arctic sea ice thins going into spring. Researchers say that as spring begins, more than 90 percent of the sea ice in the Arctic is only 1 or 2 years old. [News Source]

Arctic losing thick sea ice, U.S. data show. The amount of thick sea ice in the Arctic has shrunk sharply, according to new U.S. surveillance data, adding urgency to Canada's push to exert sovereignty in the North. [News Source]

Arctic sea ice fights losing winter battle (again). Scientists monitoring the ice’s annual growth and contraction say the frigid sheath ended winter with the fifth-smallest geographic reach since 1979, when satellites first began tracking sea-ice trends. [News Source]

Arctic ice got smaller, thinner, younger this winter. Arctic ice continued its decline this winter, with hardy, thicker old ice increasingly being replaced with quick-to-melt, thinner young ice, according to a new report by NASA and the National Snow and Ice Data Center. [News Source]

Artic ice thinner than ever: Scientists. The Arctic ice cap is thinner than ever, satellite observations revealed Monday, while also indicating that the sea ice cover continues to shrink due to global warming. [News Source]

Thinning Arctic sea ice alarms experts. The total volume of sea ice in the Arctic is likely to have reached a record low last summer, despite previous reports that the area of ice recovered slightly from the previous year's dramatic decline, leading experts have warned. [News Source]
