The UK should take active steps to prepare for dangerous climate change of perhaps 4C according to one of the government's chief scientific advisers.

In policy areas such as flood protection, agriculture and coastal erosion Professor Bob Watson said the country should plan for the effects of a 4C global average rise on pre-industrial levels. The EU is committed to limiting emissions globally so that temperatures do not rise more than 2C.

This Memorial Day I awoke in a tent high on Klahhane Ridge in Washington state's Olympic National Park. With the Strait of Juan de Fuca just to the north, and a sweeping view of Mount Olympus and the rest of the park to the south, the sunset the night before went on for hours.

After the sun set, slivers of red arched across the sky in streaks on the underbellies of a few wispy clouds. That night, the stars were so bright they ran all the way down to the horizons.

Average global temperatures keep rising. While 2016 is the warmest year on record, the previous record was set in 2015 and, before that, 2014.  A new joint report from Health Canada and the Science Media Centre of Canada (SMCC) puts this into perspective.  Canada is 1.7 degrees warmer than in 1948.

About 30% of the world’s population is currently exposed to potentially deadly heat for 20 days per year or more, and failure to reduce greenhouse gas emissions will increase the risk substantially, reports a paper published online this week in Nature Climate Change. The study suggests it is now almost inevitable that excess heat represents an increasing threat to human life, but that this threat will be greatly aggravated if greenhouse gas emissions are not considerably reduced.

Nearly a third of the world’s population is now exposed to climatic conditions that produce deadly heatwaves, as the accumulation of greenhouse gases in the atmosphere makes it “almost inevitable” that vast areas of the planet will face rising fatalities from high temperatures, new research has found.

Another month is in the global temperature record books. While May just missed setting a record, the data is another reminder that climate change is making the world hotter and pushing it into a new state.

This May was the second-warmest May on record, according to NASA data released on Thursday. The planet was 1.6°F (0.88°C) warmer than normal last month, trailing 2016 by just a 10th of a degree.

US coastal areas are set to be deluged by far more frequent and severe flooding events if greenhouse gas emissions aren’t slashed, with rare floods becoming the norm for place such as New York City, Seattle and San Diego, new research has found.

The study, undertaken by researchers from Princeton and Rutgers universities, found that along all of the US coastline, the average risk of a 100-year flood will increase 40-fold by 2050.

The Arctic's record-warm winter has allowed thousands of square miles of sea ice off Alaska to melt more than a month early, leaving the shoreline vulnerable to waves and exposing dark ocean water to absorb more heat from the sun.

The loss of ice in the Chukchi Sea will boost the regional temperature and could increase precipitation over nearby land, said Alaska-based climate scientist Rick Thoman.
