With Christmas coming soon, this effect of climate change is clearly worrying.

Scientists backing up climate data over fears it could be erased under Donald Trump

Scientists in the United States are making copies of federal climate and environmental data over fears it could be erased under Donald Trump's administration.

The mass action — being coordinated by the University of Pennsylvania's Program in the Environmental Humanities (PPEH Lab) — has been dubbed a "data rescue" and has brought together academics from across the country and in neighbouring Canada.

It aims to safeguard data "vulnerable under an administration which denies the fact of ongoing climate change" by storing it on an independent server.

Researchers are also collating a spreadsheet of the research they deem to be at risk once the President-elect takes office on January 20.

The movement was spurred by a tweet from meteorologist and journalist Eric Holthaus, who became worried after Mr Trump announced he would be appointing Exxon-Mobil Corp chairman and CEO Rex Tillerson as his secretary of state.

"I want to make sure no data is lost on Jan 20," he tweeted.

Apologies for getting the wrong person - or job. He wants Perry as Energy secretary - the department he (Perry) wanted to scrap.

Climate change: Fresh doubt over global warming 'pause'

A controversial study that found there has been no slowdown in global warming has been supported by new research.

Many researchers had accepted that the rate of global warming had slowed in the first 15 years of this century.

But new analysis in the journal Science Advances replicates findings that scientists have underestimated ocean temperatures over the past two decades.

With the revised data the apparent pause in temperature rises between 1998 and 2014 disappears.

Hausfather and colleagues decided to put together three independent data sets from satellites, buoys and robotic floats to find the true scale of ocean warming, so there was no mixing or matching of data.

"Our approach was to create three separate ocean temperature records from the three different instruments, and it turns out that all three agree really well with the new Noaa record," he said.

"The conclusion is that Noaa got it right, the scientists at Noaa were not cooking the books or manipulating the data in any way and that three independent sets of data back up their results."

"The risks of climate change are not easy to communicate clearly. Since the atmosphere affects everything, everything will be affected by its warming — there’s no single risk, but a wide and varied array of risks, of different severities and scales, affecting different systems, unfolding on different timelines. It’s difficult to convey to a layperson, at least without droning on and on."

Heatwaves to be hotter, longer and more frequent, climate change report says

Heatwaves are becoming hotter, lasting longer and occurring more often, the Climate Council's latest report card on climate change says.

The Cranking Up The Intensity: Climate Change and Extreme Weather Events report has found 2016 was the hottest year on record globally.

Climate scientist Professor Will Steffen warned extreme weather events were projected to worsen across Australia as the climate warmed further.

He said the extreme heat had to be "taken really seriously, first and foremost".

"It is a risk for human health, particularly for the most vulnerable — the elderly, very young people, and exposed outdoor workers," he said.

"It is obviously a risk for the agricultural industry, it is a risk for natural ecosystems.

Scientists watching southerly migration of tropical sea slugs to chart climate change

The National Marine Science Centre at Coffs Harbour is looking at whether the southerly migration of tropical sea slugs is an indicator of climate change.

According to researchers, south-east Australia is a recognised global climate hotspot and southward shifts in distribution have already been documented for several species.
Evidence suggests more tropical species heading south

Centre director Professor Steve Smith said colourful sea slugs were now being found up to 1,300 kilometres south of their known range.

"We're very confident about that because these are such colourful organisms that they're always seen by divers if they're around," he said.

"We know there's been a documented increase in global seawater temperatures [and] we're seeing changes in oceanographic conditions in different parts of the world.

"We know there are predictions for major changes in this part of the world.

"Certainly the evidence at the moment is suggesting that we are getting more tropical species moving further south."

In Siberia there is a huge crater and it is getting bigger

Near the Yana river basin, in a vast area of permafrost, there is a dramatic tadpole-shaped hole in the ground: the Batagaika crater.

The crater is also known as a "megaslump" and it is the largest of its kind: almost 0.6 miles (1km) long and 282ft (86m) deep. But these figures will soon change, because it is growing quickly.

Locals in the area avoid it, saying it is a "doorway to the underworld". But for scientists, the site is of great interest.

Looking at the layers exposed by the slump can give indications of how our world once looked – of past climates. At the same time, the acceleration of the growth gives an immediate insight into the impact of climate change on the increasingly fragile permafrost.

Climate sensitivity on the rise Kyle C. Armour

Recent observations of Earth’s energy budget indicate low climate sensitivity. Research now shows that these estimates should be revised upward, resolving an apparent mismatch with climate models and implying a warmer future.

Guided by models, Richardson et. al. show that accounting for this offset between sea-water and near-surface air temperatures leads to a 9% increase in global warming estimates

Furthermore, they consider the impact of incomplete geographical coverage on estimates of global-mean warming, finding that the most poorly measured regions on Earth have also warmed the most (the Arctic’s temperature is inadequately sampled, yet sea-ice has disappeared before our eyes). This is a separate 15% effect, meaning that global near-surface air warming estimates should be revised upward by 24% in total. Consequently, observation-based estimates of climate sensitivity and TCR must also be revised upward by 24%, resolving much of the mismatch with modelled values.

Climate change to blame for flatlining wheat yield gains: CSIRO

Australia's wheat productivity has flatlined as a direct result of climate change, according to CSIRO research.

While 2016 set a new national wheat harvest record, the national science organisation's findings indicate that result masks a more troubling long-term trend.

While Australian wheat yields tripled between 1900 and 1990, growth stagnated over the following 25 years.

A CSIRO study which monitored 50 sites across Australia's wheat zone between 1990 and 2015 found that climate change was the clear cause of the decline.

The CSIRO study found that wheat growers made significant productivity gains over the 26 years of the study.

But instead of that translating to significantly improved yields, the research team found that those gains were only cancelling out the negative climatic changes.

"Farmers, backed by research and by technology, have been working really hard to keep up, to adapt, to the tougher conditions, and have succeeded," Dr Hochman said.

"But they have succeeded in standing still, not in moving forward."

China's 'airpocalypse' linked to Arctic sea ice loss

The air pollution that lingered over eastern China for nearly a month in 2013 has been linked to the loss of Arctic sea ice the previous autumn.

A study says the haze lasted much longer because the melting ice and increased snowfall altered wind circulation patterns.

If Arctic ice continues to shrink due to climate change, the scientists say similar events will likely recur.

NASA has discovered a new way that global warming will accelerate the loss of the Greenland ice cap. The last two summers have been the hottest on record in Greenland. The warmer temps didn’t just accelerate the melting of the ice as would be expected, it also accelerated the flow of the ice toward the ocean by lubricating the ice/rock interface at the bottom of the glacier.

Scott Pruitt’s terrible plan to “objectively” assess climate science

The military’s experience making urgent decisions in the face of deep uncertainty will soon prove extremely valuable to all of us. Like military strategists, we will have to think in terms of risk management, make decisions based not primarily on optimality — the situation is too urgent and too uncertain for economic optimization — but on resilience.
