9 August 2017, The Conversation, Southeast Europe swelters through another heatwave with a human fingerprint. Parts of Europe are having a devastatingly hot summer. Already we’ve seen heat records topple in western Europe in June, and now a heatwave nicknamed “Lucifer” is bringing stifling conditions to areas of southern and eastern Europe. Several countries are grappling with the effects of this extreme heat, which include wildfires and water restrictions. Temperatures have soared past 40℃ in parts of Italy, Greece and the Balkans, with the extreme heat spreading north into the Czech Republic and southern Poland. Some areas are having their hottest temperatures since 2007 when severe heat also brought dangerous conditions to the southeast of the continent. The heat is associated with a high pressure system over southeast Europe, while the jet stream guides weather systems over Britain and northern Europe. In 2007 this type of split weather pattern across Europe persisted for weeks, bringing heavy rains and flooding to England with scorching temperatures for Greece and the Balkans. Read More here

7 August 2017, New York Times, Scientists Fear Trump Will Dismiss Blunt Climate Report. The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration. The draft report by scientists from 13 federal agencies concludes that Americans are feeling the effects of climate change right now. It directly contradicts claims by President Trump and members of his cabinet who say that the human contribution to climate change is uncertain, and that the ability to predict the effects is limited. “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” a draft of the report states. It was uploaded to a nonprofit internet digital library in January but received little attention until it was published by The New York Times. The authors note that thousands of studies, conducted by tens of thousands of scientists, have documented climate changes on land and in the air. “Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change,” they wrote.

4 August 2017, The Conversation, Another attack on the Bureau, but top politicians have stopped listening to climate change denial. Has the Australian climate change debate changed? You could be forgiven for thinking the answer is no. Just this week The Australian has run a series of articles attacking the Bureau of Meteorology’s weather observations. Meanwhile, the federal and Queensland governments continue to promote Adani’s planned coal mine, despite considerable environmental and economic obstacles. And Australia’s carbon dioxide emissions are rising again. So far, so familiar. But something has changed. Those at the top of Australian politics are no longer debating the existence of climate change and its causes. Instead, four years after the Coalition was first elected, the big political issues are rising power prices and the electricity market. What’s happening? Read More here
3 August 2017, The Conversation, Australia needs dozens more scientists to monitor climate properly, report says. Australia is falling short in its ability to monitor the climate, potentially leaving farmers and other groups unable to access crucial information about rainfall, droughts and floods, the Australian Academy of Science has warned. A review of Australia’s climate science capability, released today, recommends that Australia needs to recruit an extra 77 full-time climate science staff over the next four years, on top of the current 420, to meet the demand for detailed weather and climate information. Without these resources, Australia risks being unable to provide accurate information to those who need it, said UNSW oceanographer Trevor McDougall, who led the review. That could include being unable to predict accurately the changes to rainfall patterns in farming regions such as the Murray-Darling Basin – with potentially serious consequences for farmers, Professor McDougall said. Although the review says Australia is strong in some areas, such as studying extreme weather events, it identified several key shortcomings, particularly in climate modelling. Australia is not keeping pace with efforts in the United States and Europe, which are developing fine-scale climate models covering their own regions. “Other countries are not looking in detail at our country – we need to run those models ourselves,” Professor McDougall said.
