1)Global surface temperatures during the three years from 2014 to 2016 – each hotter than the last – boosted the total level of global warming since 1900 by 25%, according to new research.
2)A separate study has confirmed that heat extremes, too, have outpaced the global average. Maximum temperatures during the hottest heat waves have in the last 30 years risen three times faster – especially in crowded cities that are home to more than 10 million – than average temperatures as a whole.
3)And a third study warns that unless the world’s nations start to reduce carbon emissions, then within the next 17 or 18 years, planetary temperatures will be at least 1.5°C above the world average for most of human history.
And 35 to 41 years from now, these temperatures will have climbed 2°C above the level that held before the Industrial Revolution, and the arrival of fossil fuels as a global energy source.
1)Oceans act as a sink for warmth, it takes them a long time to warm or cool through their sheer volume. In 2017 they were the warmest ever recorded.
2)2017 was the second or third warmest year recorded, depending on which dataset was used. Of significance, 2017, was the warmest year recorded without the influence of an El Nino event.
3)The Arctic sea ice extent and volume have continued to decrease, the lowest extent in September was the eighth lowest ever recorded. Volume has changed downward by about 80% since 1979.
4)Antarctic is being investigated quite profusely at present, its sea ice has been at low levels. The huge 5,698 square kilometre Larson C ice sheet broke clear in July 2017. A number of major ice sheets are considered to be at risk as grounding lines are moving shorewards.
What the scientists found is that five of the bears lost weight and four of them lost 2.9 to 5.5 pounds (1.3 to 2.5 kilograms) per day. The average polar bear studied weighed about 386 pounds (175 kilograms). One bear lost 51 pounds (23 kilograms) in just nine days.
Trump’s tweet was “troll-like”, the scientist said, showing the president “delighting in sparking outrage among [his] opponents”.
With Tony Abbott and Ian Plimer’s global activism, Australia appears to fast becoming the home of worldwide climate science denialism. Graham Readfearn reports.
AUSTRALIANS HAVE been keeping the London-based climate science denial group the Global Warming Policy Foundation (GWPF) busy in recent weeks, writes Graham Readfearn.
After former Prime Minister Tony Abbott gave the group’s annual lecture in October, it was the turn of one of Australia’s longest-serving deniers to empty another bucket of bunkum.
Professor Ian Plimer, an Australian director of multiple mining companies, is featured in a new interview with the GWPF to promote his latest subtly titled denial tome: Climate Change Delusion and the Great Energy Rip-off.
When it comes to climate change science, Plimer can be placed very firmly in the file marked “denial
At COP23, the International Energy Agency predicts U.S. oil production is expected to grow an an unparalleled rate in the coming years—even as the majority of scientists worldwide are saying countries need to cut down on fossil fuel extraction, not accelerate it. Meanwhile, a group of 15,000 scientists have come together to issue a dire “second notice” to humanity, 25 years after a group of scientists issued the “first notice” warning the world about climate change.
That this is the best we can do — indeed that this is a relative triumph for Mr. Turnbull — illustrates just how tangled Australia’s climate politics have become. The country has taken a long, hard look at every warning about the costs of delayed climate action and ignored them all. And, subsequently, it has paid for those costs through high energy prices and curtailed investment.

In fact, given the patent inaccuracy of his remarks, it’s no surprise he had fly 10,000 miles to find an audience sufficiently receptive, or adequately ignorant of Australia’s climate record, to actually listen.
Puerto Rico Quick Facts
- Petroleum products fuel transportation, electricity generation, and industry in Puerto Rico, supplying three-fourths 75% of the energy consumed in the commonwealth.
- In 2016, 47% of Puerto Rico’s electricity came from petroleum, 34% from natural gas, 17% from coal, and 2% from renewable energy.

Hurricane Irma pounded Cuba’s northern coast on Saturday and barrelled toward Florida as authorities scrambled to complete an unprecedented evacuation of millions of residents hours before the storm would engulf the state.
Destructive force of Irma and Harvey has Trump expressing awe, but those in power should focus on the environmental causes
Reuters quoted a market analyst as saying, “Imports can’t make up for this. . . This is going to be the worst thing the U.S. has seen in decades from an energy standpoint.”Not only is gasoline going to be more expensive as a result, but the pollution dangers from the damaged refineries are horrific.But guess what? Texas’s wind turbines weathered Harvey. Some were pushed to the max by its powerful winds, but they just went on making electricity! Turbines shut down if the wind is 55 mph or more, but most wind farms affected by Harvey were able to keep operating. One shut down because the electrical wires were knocked down, not because the turbines stopped working!. On an average day, Texas gets 20% of its electricity from wind. That only fell to 13% the day of Harvey’s landfall.

Hurricane Harvey, now weakened to a tropical depression, has caused widespread devastation along the Texas coast, including record rainfall and flooding comparable to 2005’s Hurricane Katrina. Relief efforts will be costly and take years, authorities say.
This is not an administration, it is a rogues gallery of environmental criminals.Want to know why we’re having a once in a 500 years storm and flood in Texas?Because of Trump and his buddies on the cabinet. They are creating a situation where Hurricane Harvey becomes the new normal.They should resign.
This is no time to take the high moral ground.
This week, our hearts are heavy and our thoughts are with everyone affected by Hurricane Harvey. As climate scientist Dr. Michael Mann wrote, “[W]e can’t say that Hurricane Harvey was caused by climate change. But it was certainly worsened by it.”
The report is concrete, careful and scarier than any horror movie you’ve ever seen. It gives upper and lower estimates, depending on whether humankind gets its act together. Given the oil-drenched buffoons now in charge, you’d want to bet on the higher and more dangerous numbers in each case.

Since 1880, after carbon dioxide emissions took off with the Industrial Revolution, the average global temperature has increased. With the help of internal variations associated with the El Niño weather pattern, we’ve already experienced months more than 1.5℃ above the average. Sustained temperatures beyond the 1℃ threshold are imminent. Each of the last three decades has been warmer than the preceding decade, as well as warmer than the entire previous century.
