The increasing rate of the global mean surface temperature was reduced from 1998 to 2013, known as the global warming hiatus or pause. Great efforts have been devoted to the understanding of the cause. The proposed mechanisms include the internal variability of the coupled ocean-atmosphere system, the ocean heat uptake and redistribution, among many others. However, the atmospheric footprint of the recent warming hiatus has been less concerned.
Both the dynamical and physical processes remain unclear. In a recent paper published in Scientific Report, LIU Bo and ZHOU Tianjun from the Institute of Atmospheric Physics, Chinese Academy of Sciences have investigated the atmospheric anomalous features during the global warming hiatus period (1998-2013). They show evidences that the global mean tropospheric temperature also experienced a hiatus or pause. —Chinese Academy of Science, March 2017
A former scientist at the NOAA has exposed a shoddy report on global warming. Judicial Watch is suing to learn more. Following allegations of impropriety over the handling of a controversial climate change report, a government watchdog group now wants to know whether there was any collaboration between the report’s lead author and a key Obama adviser. On March 27, Judicial Watch filed a lawsuit seeking “all records of communications between a pair of federal scientists who heavily influenced the Obama administration’s climate change policy and its backing of the Paris Agreement.” The FOIA specifically requests correspondence between Tom Karl, the former head of the climate-data program at the National Oceanic and Atmospheric Administration (NOAA), and John Holdren, the director of Obama’s Office of Science and Technology Policy. –Julie Kelly, National Review, 6 April 2017
As we head into April, the Southern Hemisphere is in the midst of the “quietest” hurricane season on record. Meteorologist Ryan Maue of Weatherbell Analytics noted tropical cyclone activity in the Southern Hemisphere for the 2016-2017 season is the “quietest on record, by far” based on records going back nearly five decades. –Michael Bastasch, The Daily Caller, 4 April 2017
Poland doesn’t agree with the introduced European Union (EU) climate policy norms, Polish Prime Minister Beata Szydlo announced Wednesday. “As for climate policy, our position is clear: we do not agree with the norms that have been introduced. We will be consistent in protesting and looking for new solutions,” Szydlo said. The prime minister added that the EU climate norms were not only problem to Polish economy but to the other central European countries as well. “We will protect our economy,” Szydlo said. —The Global Times, 6 April 2017
The British government is assessing ways to scrap pledges made to hit 2020 clean energy targets without incurring any penalties, reports Bloomberg, in a first sign of the country reneging on mandatory environmental action made under EU membership. The U.K.’s treasury and business department is seeking ways to scrap the country’s binding EU target of sourcing 15% of its energy from renewable sources by 2020, reports Bloomberg. —PV Magazine, 6 April 2017
Science journalism is about “shaking the tree,” about asking awkward questions, about standing in the place of those who can’t ask such questions, and being persistent and unpopular. It is a vital aspect of democracy. In far too many countries journalists are told what to say, and told what not to say. Being able to speak freely without censorship is fundamental to modern liberal democracies and is guaranteed under national and international law. The important point is that the freedom of speech principle does not mean that you have to be factually accurate. Sure, one should never lie and always strive to be accurate. But what looks right today can turn out to be wrong tomorrow, especially in science. It is freedom, not accuracy that is supreme. We at the GWPF frequently challenge others we disagree with. You can do the same. That’s why we stand up for this freedom. –David Whitehouse, GWPF Observatory, 31 March 2017
