June 2017 was beaten only by June in 2015 and 2016, leaving experts with little hope for limiting warming to 1.5C or even 2C

Last month was the third-hottest June on record globally, temperature data suggest, confirming 2017 will almost certainly make a hat-trick of annual climate records, with 2015, 2016 and 2017 being the three hottest years since records began.

This week, to accompany our cover story on worst-case climate scenarios, we’re publishing a series of extended interviews with climatologists on the subject — most of them from the “godfather generation” of scientists who first raised the alarm about global warming several decades ago.

Conclusions include:

1. Global warming in the past 50 years has raised global temperature (Fig. 1) well above the prior range of the Holocene (the current interglacial period approximatly the 11,700 years) to the level of the Eemian period (130,000 to 115,000 years ago) when sea level was 6-9 meters (20-30 feet) higher than today.

Some puzzles, like the climate hiatus, may seem entirely academic. But they do answer big questions about long-term warming predictions.

In the Paris accord, 195 countries agreed that they would collectively keep average global temperatures from rising more than 2 degrees. But what does science have to say on how fast, and by how much, will we have to cut our emissions to get there? Professor Kevin Anderson of the Tyndall Centre is a climate scientist who looks at exactly this question. And the math he comes away with, isn't pretty.

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.
