Climate science discovers more bad news

❝ A new US government report delivers a dire warning about climate change and its devastating impacts, saying the economy could lose hundreds of billions of dollars — or, in the worst-case scenario, more than 10% of its GDP — by the end of the century.

❝ The federally mandated study was supposed to come out in December but was released by the Trump administration on Friday, at a time when many Americans are on a long holiday weekend, distracted by family and shopping…

“The global average temperature is much higher and is rising more rapidly than anything modern civilization has experienced, and this warming trend can only be explained by human activities,” NOAA’s David Easterling said…

❝ The report’s findings run counter to President Donald Trump’s consistent message that climate change is a hoax.

On Wednesday, Trump tweeted, “Whatever happened to Global Warming?” as some Americans faced the coldest Thanksgiving in over a century.

But the science explained in these and other federal government reports is clear: Climate change is not disproved by the extreme weather of one day or a week; it’s demonstrated by long-term trends. Humans are living with the warmest temperatures in modern history…

History will answer whether Trump is a pathological liar, incredibly ignorant or just a crook! Meanwhile, we need to get on with trying to turn the United States to playing a constructive and useful role in economics and environmental health.

Yukon glaciers thinning fast — maybe forever!

❝ “We as Canadians are stewards of about a third of the world’s mountain glaciers and ice caps, so this is our responsibility,” Gwenn Flowers says.

The dramatic changes to the glaciers in the Yukon are an early warning of what climate change could mean for the rest of the planet, researchers say. And Flowers sees lots of reason for concern reflected in the state of the ice…

❝ Her tiny team of three is mapping the Kaskawulsh glacier — 70 kilometres long and five kilometres wide — as it struggles under the double threat of a warming climate and diminishing snow cover.

The research boils down to an inescapable conclusion: The glacier can’t compensate for the volume it’s losing now each year.

The shame is that those who have caused – and continue to cause – climate change take little or no responsibility for the results of their greed. Neither they nor the political hacks prancing through government halls are willing to confront or respond to what we learn from science and history.

Climate Change Redraws the Map


Tornado Alley moves 500 miles east in the last 30 years

❝ As human-caused emissions change the planet’s atmosphere, and people reshape the landscape, things are changing fast. The receding line of Arctic ice has made headlines for years, as the white patch at the top of our planet shrinks dramatically. The ocean is rising, gobbling up coastlines. Plants, animals, and diseases are on the move as their patches of suitable climate move too.

Sometimes, the lines on the map can literally be redrawn: the line of where wheat will grow, or where tornadoes tend to form, where deserts end, where the frozen ground thaws, and even where the boundaries of the tropics lie.

❝ The Yale School of Forestry & Environmental Studies summarizes some of the littler-known features that have shifted in the face of climate change and pulled the map out from under the people living on the edges. Everything about global warming is changing how people grow their food, access their drinking water, and live in places that are increasingly being flooded, dried out, or blasted with heat waves. Seeing these changes literally drawn on a map helps to hammer these impacts home.

Had some great friends at Yale Forestry over the years. The school has done wonderful serious science on climate change. A worthwhile read.

Beer Prices May Double Because Of Climate Change — GASP!

❝ The price of beer could rise sharply this century, and it has nothing to do with trends in craft brewing. Instead, a new study says beer prices could double, on average, because of the price of malted barley, a key ingredient in the world’s favorite alcoholic drink.

By projecting heat and drought trends over the coming decades, a team of researchers in China, the U.K. and the U.S. found that barley production could be sharply affected by the shifting climate. And that means some parts of the world would very likely be forced to pay much more for a beer…

❝ The researchers acknowledge that the price of beer is “not the most concerning impact of future climate change.” But in the study published Monday in the journal Nature Plants, the scientists say they wanted to use beer as an example to show the deep and wide-ranging effects of increasingly extreme weather.

RTFA. Lots of info to stuff in the ear of your favorite recalcitrant Republican political hack!

FIRE SCIENTISTS ARE CONFIDENT: THIS WILL GET WORSE

❝ As of July 31, more than 25,000 firefighters are committed to 140 wildfires across the United States—over a million acres aflame. Eight people are dead in California, tens of thousands evacuated, smoke and pyroclastic clouds are visible from space. And all any fire scientist knows for sure is, it only gets worse from here. How much worse? Where? For whom? Experience can’t tell them. The scientists actually are uncertain.

❝ Scientists who help policymakers plan for the future used to make an assumption. They called it stationarity, and the idea was that the extremes of environmental systems—rainfall, river levels, hurricane strength, wildfire damage—obeyed prior constraints. The past was prologue. Climate change has turned that assumption to ash…

❝ Wildfires were always part of a complex system. Climate change—carbon dioxide and other greenhouse gases raising the overall temperature of the planet—added to the complexity. The implications of that will play out for millennia. “On top of that is interaction between the climate system, the ecosystem, and how we manage our land use,” Westerling says. “That intersection is very complex, and even more difficult to predict. When I say there’s no new normal, I mean it. The climate will be changing with probably an accelerating pace for the rest of the lives of everyone who is alive today.”

Fools who voted for Trump not only fooled themselves – they have condemned their children, grandchildren and generations to come to the new holocaust.

Fighting wildfires is becoming more and more expensive

❝ Just six months after the devastating Thomas Fire – the largest blaze in California’s history – was fully contained, the 2018 fire season is well under way. As of mid-July, large wildfires had already burned over 1 million acres in a dozen states. Through October, the National Interagency Fire Center predicts above-average wildfire activity in many regions, including the Northwest, Interior West and California.

Rising fire suppression costs over the past three decades have nearly destroyed the U.S. Forest Service’s budget. Overall funding for the agency, which does most federal firefighting, has been flat for decades, while fire suppression costs have grown dramatically.

❝ Earlier this year Congress passed a “fire funding fix” that changes the way in which the federal government will pay for large fires during expensive fire seasons. This is vital for helping to restore the Forest Service budget. But the funding fix doesn’t affect the factors that drive costs, such as climate trends and more people living in fire prone landscapes…

Why are costs increasing so dramatically? Many factors have come together to create a perfect storm. Climate change, past forest and fire management practices, housing development, increased focus on community protection and the professionalization of wildfire management are all driving up costs.

What can we expect as a response from a Congress that as presently constituted answers mostly to a base that wants fewer costs, no taxes and, of course, no responsibility for any environment?
