17 February 2018, Independent, Global sea ice hits record low for January as the annual polar melting period expanded. The world’s sea ice shrank to a record January low last month as the annual polar melting period expanded, experts say. The 5.04 million square miles of ice in the Arctic was 525,000 square miles below the 1981-to-2010 ice cover average, making it the lowest January total in satellite records, according to the US National Snow and Ice Data Center (NSIDC). Combined with low levels in the Antarctic, global sea ice amounted to a record low for any first month of the year, the organisation concluded. The news comes just days after researchers from the University of Colorado Boulder said the rate at which sea levels are rising was increasing every year, driven mostly by accelerated melting in Greenland and Antarctica. The NSIDC, a respected authority on the Earth’s frozen regions, which researches and analyses snow, glaciers and ice sheets among other features, said that ice in the Arctic Ocean hit “a new record low” at both the start and end of last month. In an online post, the group said: “January of 2018 began and ended with satellite-era record lows in Arctic sea ice extent, resulting in a new record low for the month. Combined with low ice extent in the Antarctic, global sea ice extent is also at a record low.” Read More here

16 February 2018, The Guardian, It’d be wonderful if the claims made about carbon capture were true. The International Energy Agency warned this week that, under current energy policies, Australia is unlikely to meet its 2030 climate commitments. While the agency had lots to say about the plunging costs of renewables and the need for strong market signals to encourage the retirement of old and inefficient coal generation, Josh Frydenberg, the federal environment and energy minister, seized on the agency’s support for carbon capture and storage (CCS) – despite the technology’s long history of big promises and meagre results. Last April, Frydenberg visited the newly opened Petra Nova CCS project in Texas. In a video posted to social media the minister, decked out in the obligatory hi-vis vest and hard hat, yells above the noise that the $1bn project is “helping to reduce the carbon footprint by some 40%”. It’d be wonderful if it were true. An estimated 6.2% of the Petra Nova power station’s emissions are captured, compressed and then piped 130km to help extract stubborn oil out of a depleted oil field. In the process, an estimated 30% of the carbon dioxide leaks back into the atmosphere, not to mention the emissions that will ultimately be released when the extracted oil is consumed. Last month, the Minerals Council of Australia was spruiking the “21 large-scale CCS facilities in operation or under construction around the world including in Canada and Texas”. Sounds impressive, if you still trust the MCA’s spin. You shouldn’t – 19 of the 21 projects have nothing to do with coal; there are exactly two “large scale” coal CCS projects globally. And, no, they’re not large. The Canadian project, Boundary Dam, has averaged only 0.591 million tonnes of carbon dioxide over each of its first three years. The $1.5bn project would need to be scaled up 31 times to capture the emissions of New South Wales’s Bayswater power station – an inconceivable investment. Read More here
13 February 2018, Under the Paris Agreement, governments worldwide agreed to hold global warming “well below 2C” and to aim for 1.5C. The inclusion of that second, tougher, goal was a victory for small island states and other countries on the front line of climate change. It was an acknowledgement of fears that higher temperature rise posed an unacceptable threat to their futures. But the vast bulk of research and analysis prior to 2015 centred on the 2C threshold, a more established international target. What would it take to bend the curve to 1.5C? Enter the Intergovernmental Panel on Climate Change (IPCC). The climate science body agreed to produce a special report on 1.5C, summarising all the available evidence. Climate Home News has obtained an early version of the five-chapter report, which is due to be finalised in September. The IPCC stressed it was a work in progress and may change substantially. It is open for review by experts and governments, and may incorporate further studies published by 15 May. Read the draft summary for policymakers in full here. What is clear from the content so far, though, is there is not much time left. Here are the main takeaways. Read More here
13 February 2018, NASA Goddard Institute, The rate of global sea level rise has been accelerating in recent decades, rather than increasing steadily, according to a new study based on 25 years of NASA and European satellite data. This acceleration, driven … Continue reading →
