I’ll come back to that. However, Tamino at Open Mind points out that while the Arctic warms three to four times as fast as global warming, the Arctic winters are warming at a much faster rate.
Using the NASA data, which is about mid-range in the major players, Tamino finds that the overall average warming rate since 1985 in the Arctic, at 6.48°C/century is fully 3.4 times as fast as the global rate since 1985 of 1.90°C/century. Continue reading Trouble at the top of the world→
The government has produced the latest State of the Environment Report 2016 which happens every five years. I’ve browsed the report and can say that it has some magnificent photographs.
According to the ABS Australia’s population will be between 36.8 million and 48.3 million in 2066 as against 24 million now. The report says that the key drivers of environmental change are population growth and economic activity.
CSIRO researcher Dr Pep Canadell said it was the most comprehensive modelling to date and revealed a potentially dangerous climate wildcard.
“Methane emissions were stable for quite a few years at the end of the 2000s. But they’ve begun to grow much faster, in fact 10 times faster, since 2007,” said Dr Canadell, who is also the executive director of the Global Carbon Project.
Tesla founder and CEO Elon Musk has again set tongues wagging, this time with his declaration last week that his newly launched integrated solar roof tiles could actually cost less to install than a regular roof – making the renewable electricity they produce “just a bonus”.

Business, investor, environment, research and social groups have formed an unprecedented alliance to establish common ground on which the climate debate can be conducted, as the Abbott government finalises the position it will take to Paris climate talks later in the year.
The Australian Industry Group, the Business Council of Australia, Investor Group on Climate Change, the Australian Aluminium Council and the Energy Supply Association of Australia have joined forces with the Australian Conservation Foundation, WWF Australia, the Australian Council of Social Service and the Australian Council of Trade Unions to set down some basic markers on climate policy which they hope will allow for future political consensus on the issue.
Every year climbers of Mt Everest leave behind 26,500 pounds of poo. I make that about 12 tonnes.
Sherpas pick it up, bring it down in blue barrels, dig a hole and dump it. Now the proposal is to build an anaerobic digester in a small village near Everest’s base to create biogas to produce power. Apparently human poo is not the best, but it works.
2. Arctic sea ice record
I think it’s time to call it. The Arctic sea ice winter maximum is the lowest on record. This graph shows 2015 ice against the previous record of 2011 and the 1981-2010 average:
Also the maximum extent was reached on February 25, the second earliest on record.
Shell hopes to drill in the Chukchi Sea in the Arctic this summer. It looks as though Obama’s Department of the Interior will allow it, even though an Environmental Impact Report released by the Bureau of Ocean Energy Management (BOEM) noted a 75% chance of one or more large spills occurring under the current plan. In 1989 the Exxon Valdez disaster spilled nearly 11 million gallons of crude oil into the Alaskan Gulf, polluting over 1300 miles of coastline. It is estimated that only 14% of the oil was cleaned up.
By comparison BP’s Deepwater Horizon oil rig spilled 168 million gallons of oil into the Gulf of Mexico off the Louisiana coast.
Yet Obama himself stresses the need to move early on climate change. More than half of Republican politicians deny or question the science. Voter pressue will change that eventually.
A recent Stanford University poll found that two-thirds of voters were more likely to vote for a candidate that campaigned on a platform of fighting climate change, and were less likely to vote for a candidate that outright denies climate change.
We are destroying nature’s ability to help us stave off catastrophic climate change. That’s the bombshell conclusion of an under-reported 2014 study, “The declining uptake rate of atmospheric CO2 by land and ocean sinks,”…
Based on actual observations and measurements, the world’s top carbon-cycle experts have determined that the land and ocean are becoming steadily less effective at removing excess carbon dioxide from the atmosphere. This makes it more urgent for us to start cutting carbon pollution ASAP, since it will become progressively harder and harder for us to do so effectively in the coming decades.
Joe Romm calls the study “one of the most consequential recent findings by climatologists”
More than half of emissions are currently absorbed by land and ocean-based carbon sinks. Increasingly these emissions will stay in the air.
