*****True 'pre-industrial' period (incl interview w Ed Hawkins) Image copyright Getty Images Scientists are seeking to define a new baseline from which to measure global temperatures - a time when fossil-fuel burning had yet to change the climate. At the moment, researchers tend to use the period 1850-1900, and this will often be described as "pre-industrial". ***Norway fund could trigger wave of large fossil fuel divestments, say experts Norway’s decision to dump all coal-focused investments from its $900bn sovereign wealth fund could unleash a wave of divestment from other large funds, according to investment experts. The fund, the largest in the world, is one of the top 10 investors in the global coal industry. The move, agreed late on Wednesday, is one of the most significant victories to date for a fast-growing and UN-backed fossil-fuel divestment campaign.

History of Earth's surface temperature 1880-2016 2016 is officially the new warmest year on record, edging out previous record holder 2015 by 0.07°F, according to NOAA. It is the third year in a row that global average surface temperature set a new record, and the fifth time the record has been broken since the start of the twenty-first century. This animation shows annual temperatures each year since 1880 compared to the twentieth-century average, ending with record-warm 2016. Because of global warming due to increasing greenhouse gases, the maps from the late 1800s and the early 1900s are dominated by shades of blue, indicating temperatures were up to 3°C (5.4°F) cooler than the twentieth-century average.

Hinkley Point C subsidy scheme being investigated by National Audit Office The National Audit Office has begun an investigation into the controversial subsidy regime for the planned new Hinkley Point C nuclear plant in Somerset, a week after Brussels approved taxpayer support for the project. The financial watchdog, which scrutinises public spending on behalf of parliament, said it would be checking whether the guaranteed prices of £92 a megawatt hour – double the current cost of electricity – represented “value for money”. The NAO move, which follows pressure from a House of Commons committee, puts pressure on the government but has pleased green groups which believe nuclear is getting preferential treatment over windfarms.

What Can Beetles Tell Us About Past Climates? I tried this method on a second fossil site at Ziegler Reservoir, which is located near Snowmass Village, a ski resort in Colorado. In 2010, work began to widen the reservoir, but the remains of a mammoth were uncovered, leading to a paleontological expedition. Numerous mastodon, mammoths, ground sloths, bison and camels - as well as insects - were excavated from the site. Carbon dating indicates the age of the site ranges from 126 to 77 thousand years. The analysis produced a mass of conflicting information. Beetles were found a wide range of climate zones, often with no overlap.

Frightened by Donald Trump? You don’t know the half of it Yes, Donald Trump’s politics are incoherent. But those who surround him know just what they want, and his lack of clarity enhances their power. To understand what is coming, we need to understand who they are. I know all too well, because I have spent the past 15 years fighting them. 19th Century Landscape Paintings Shed Light On Early Days Of Climate Change Hard data on the annual rise and fall of Earth’s global surface temperatures only goes back about 150 years. Before then, there were few instruments available to monitor changes in the planet’s atmosphere. To get an idea of what the skies were like before the 20th century, scientists are getting help from an unlikely source: 18th- and 19th-century landscape paintings. Undergrounding - www.kentdowns.org.uk Since 2006 UK Power Networks, working in association with Natural England and AONBs across the region, will have removed over 115km of visually intrusive overhead power lines from protected landscapes in the South East of England. In the Kent Downs over 23km of overhead cabling has been removed. This work has been made possible by a special allowance granted by the electricity regulator Ofgem to remove overhead lines from protected landscapes such as Areas of Outstanding Natural Beauty (AONB’s) and National Parks. How are schemes selected? Successful projects are identified and determined by a regional steering group comprising of representatives of the AONB and national park management units, and chaired by Natural England.

Sea Ice Hits Record Lows at Both Poles Arctic temperatures have finally started to cool off after yet another winter heat wave stunted sea ice growth over the weekend. The repeated bouts of warm weather this season have stunned even seasoned polar researchers, and could push the Arctic to a record low winter peak for the third year in a row. Meanwhile, Antarctic sea ice set an all-time record low on Monday in a dramatic reversal from the record highs of recent years. *****4 levels of computer skills, and the surprising number of adults who fall short It’s easy to assume that almost everyone, particularly in rich nations, is computer literate. After all, nearly half the world’s adults have a smartphone. In the age of the Fourth Industrial Revolution, online skills are more important than ever before.

Seen by its southern neighbour as quaint but decidedly boring, Canada is perhaps best known around the world for its unusual police uniform, propensity to produce singers and a controversial tar sands industry. So how come it suddenly got hip? ***Google Earth animations: 30 Years of Climate Change Satellites have revolutionized the way we see the world. Since the first satellite image of earth was taken in 1959, they’ve captured a world reshaped by humans. Cities have risen, lakes have dried out, ice shelves have disappeared and the future of energy has begun popping up in deserts and fields around the world. Human ingenuity put the satellites into orbit hundreds of miles above the earth to chronicle these changes. And now human ingenuity has strung together decades of images to crystalize what those changes look like in every corner of the globe.
