28 March 2016, NASA, 2016 Arctic sea ice wintertime extent hits another record low. Arctic sea ice appears to have reached a record low wintertime maximum extent for the second year in a row, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA. Every year, the cap of frozen seawater floating on top of the Arctic Ocean and its neighboring seas melts during the spring and summer and grows back in the fall and winter months, reaching its maximum yearly extent between February and April. On March 24, Arctic sea ice extent peaked at 5.607 million square miles (14.52 million square kilometers), a new record low winter maximum extent in the satellite record that started in 1979. It is slightly smaller than the previous record low maximum extent of 5.612 million square miles (14.54 million square kilometers) that occurred last year. The 13 smallest maximum extents on the satellite record have happened in the last 13 years. The new record low follows record high temperatures in December, January and February around the globe and in the Arctic. The atmospheric warmth probably contributed to this lowest maximum extent, with air temperatures up to 10 degrees Fahrenheit above average at the edges of the ice pack where sea ice is thin, said Walt Meier, a sea ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

28 March 2016, Energy Post, Wake up call for oil companies: electric vehicles will deflate oil demand. The major oil companies greatly underestimate the impact electric vehicles will have on their market, write independent energy advisors Salman Ghouri and Andreas de Vries. According to Ghouri and De Vries, the trends currently underway in the auto industry are likely to have a substantial impact on oil demand in the medium term, and even a devastating impact in the longer term. If there is one event in history that has shaped the crude oil industry, it is the popularization of the internal combustion engine (ICE) by the auto industry. At the beginning of the 20th century, coal and wood were the dominant sources of energy, together providing more than 90% of global energy consumption. From 1910 onward, however, the Automotive Revolution triggered by Henry Ford spurred on demand for liquid fuels, causing crude oil’s contribution to global energy supply to more than double every decade. Consequently, by 1970 crude oil had taken top-spot in the global energy mix. Continued growth in the transportation sector ever since has provided the world’s oil companies with plenty of organic growth opportunities. And judging by the energy outlooks the major oil companies have published, they appear to expect this status quo to continue. For example, BP’s most recent Energy Outlook 2035 assumes that non-oil based transport will grow just 5% per annum for the next 20 years, and that essentially all of this growth will be in the gas-powered transport segment. Similarly, The Outlook for Energy: A View to 2040 published by ExxonMobil assumes that by 2040 “plug in” electric vehicles (EVs) and fuel cell vehicles (FCVs) will have no more than a 4% market share. Chevron, meanwhile, has indicated that it plans on the basis of the assumption that the auto industry will remain fundamentally the same for at least another 50 years. Alternative assumptions However, as we documented elsewhere, the auto industry itself expects its future to be radically different from its present. To assess how the new vision of the auto industry would impact crude oil demand, we have developed an Alternative Energy Outlook (AEO). Read More here
27 March 2016, Climate News Network, Renewable energy demands the undoable. Switching to renewable energy as fast as the world needs to will require changes so massive that they are unlikely to happen, scientists say. The world is increasingly investing in renewable energy. Last year, according to UN figures, global investment in solar power, wind turbines and other renewable forms of energy was $266 billion. This was more than double the investment of $130bn in coal and gas power stations in 2015. It sets a new investment record and brings spending on renewable energy since 2004 to a total, adjusted for inflation, of $2.3 trillion. And, says the United Nations Environment Programme’s report on Global Trends in Renewable Energy Investment 2016, that same push added 134 gigawatts (one gigawatt is reckoned enough to supply the needs of 750,000 typical US homes) of renewable power worldwide. It also spared the atmosphere the burden of an estimated 1.5 gigatonnes of carbon dioxide emissions (human activities, chiefly the burning of fossil fuels and changes in land use, add an extra 29 gigatonnes of CO2 to the atmosphere annually). Not enough But right now, the report says, renewable energy sources deliver just 10.3% of global electrical power. Neither the report’s authors nor anyone else thinks that is enough to slow climate change driven by rising global temperatures as a consequence of greenhouse gas emissions from fossil fuels.

25 March 2016, Climate News Network, Past emissions cause mounting climate havoc. Despite signs that the world will cut its future fossil fuel use, greenhouse gases already emitted are still driving accelerating climate change.Climate change has reached the point where it may outstrip the quickening efforts to slow it by reducing emissions of carbon dioxide and other greenhouse gases, scientists say. They say humans are now releasing CO2 into the atmosphere 10 times faster than natural processes have ever done in the last 66 million years, before the extinction of the dinosaurs. The disclosure comes in the World Meteorological Organisation’s State of the Climate report, published in the journal Nature Geoscience. The lead author, Professor Richard Zeebe of the University of Hawaii, said: “Our carbon release rate is unprecedented over such a long time period [and] means that we have effectively entered a ‘no-analogue’ state. “The present and future rate of climate change and ocean acidification is too fast for many species to adapt, which is likely to result in widespread future extinctions.” “The window of opportunity for limiting global temperature rise to well below 2°C . . . is narrow and rapidly shrinking. The effects of a warming planet will be felt by all” The UN secretary-general, Ban Ki-moon, said: “Climate change is accelerating at an alarming rate. The window of opportunity for limiting global temperature rise to well below 2°C – the threshold agreed by world governments in Paris in December last year – is narrow and rapidly shrinking. The effects of a warming planet will be felt by all.” The WMO secretary-general, Petteri Taalas, said the present “alarming” rate of climate change as a result of greenhouse gas emissions was “unprecedented in modern records”. “The future is now”, he said. Yet less than a week ago the International Energy Agency announced that global energy-related emissions of carbon dioxide had shown no increase for the second year in a row. The announcement was widely hailed as significant good news, with the IEA’s executive director, Fatih Birol, describing it as “yet another boost to the global fight against climate change”.Read More here
