Australia — Public cooling rooms could be set up across Australia to allow people to take refuge from the country’s worsening heatwaves under a proposal circulated in a new climate change report.

May: Balcony lightshow, Darwin, Northern Territory. When Mark Percival lived at Palmerston in the Northern Territory, inland of Darwin, he enjoyed photographing tropical thunderstorms from his second-floor balcony. Northern parts of the Territory experience two distinct seasons, the Dry (May to September), and the Wet (October to April the following year).The Wet is characterised by more thunderstorms and monsoon activity due to higher rainfall, temperature and humidity. A shift in the prevailing wind also directs more moisture into the Darwin region from warm oceans north of Australia. On average, Darwin experiences 20 days with thunder each December.

Severe heat waves kill more Australians each year than any other natural disaster, mainly via heat stroke and heat exhaustion.

But the heat waves are expected to get hotter and longer, according to the report by PricewaterhouseCoopers and government and meteorology experts.

The country’s heat-related death toll is set to more than double by 2050.

The report says Australia has done little to prepare for a new era of heatwaves and tends to focus on large-scale natural disasters such as bushfires and floods – even though such events often take fewer lives.

During the week of the 2009 Victorian bushfires, for instance, 173 people died in the fires and 374 people died due to extreme heat.
The report says the Government should consider a “national heat wave plan”, including cooling rooms to provide respite from 45-plus degree days.

The rooms – air-conditioned government or community halls – would be positioned in urban centres and accessible in cases of severe weather.

Other proposals include early warning systems and programs adopted by cities such as Shanghai and Chicago to increase vegetation and promote rooftop gardens.

The report says Australia will go from 10 extremely hot days a year to 25 in 2050 and the average number of heat-related deaths will rise from to more than 1000.

“The incidence of severe and extreme heat events in Australia has been considerable and is projected to increase,” it said. “The north-west is expected to warm more quickly than the rest of Australia, and inland areas will experience greater warming than coastal regions.”

The world’s longest heatwave was recorded in Australia, where Marble Bar in Western Australia-registered 160 consecutive days above 100°F (or 37.8°C) from 31 October 1923 to 7 April 1924.

Rural areas to pay $150 state fire fee

USA — About 25,000 housing units in Calaveras County fall in the State Responsibility Area and residents may have to pay a $150 fee to fund Cal Fire’s efforts to protect state resources.

Cal Fire is responsible for protecting 31 million acres, about one-third of the state; 500,000 of those are in Calaveras County.

“Typically those are more rural areas that have some type of environmental value to the state, such as timber, forest land or watershed,” according to Daniel Berlant, Cal Fire spokesperson.

Jim Carroll, West Point Fire Protection District chief, said that people in his district would “probably be extremely unhappy” if the fee goes through.

“It’s not really going to benefit us in terms of fire protection,” he said. “My personal opinion is that this is a method to balance the (state) budget.”

When asked if it was fair for more than 850,000 rural property owners to pay for the protection of resources that benefit out-of-area stakeholders, Berlant said that was a popular argument against the fee.

“You’d have to talk to the other side. That is a common argument from the other side.”

Berlant emphasized that Cal Fire does not take a position for or against the fee.

“We work for the governor. Our job is to implement the law.”

The controversy began in July, when Gov. Jerry Brown signed a bill authorizing a new fire prevention fee of up to $150 for housing units in the SRA, the state responsibility area.

In August, the state Board of Forestry and Fire Protection capped the fee at $90. Most residents within the SRA would qualify for exemptions, which would lower the fee to $25.

Brown had pushed to pass the higher fee in order to raise $50 million in new state revenue to help pay for Cal Fire to protect the millions of acres under its watch.

Berlant said that since January, Cal Fire’s funding has been slashed by $70 million.

“The state is in a major fiscal crisis. In every department, cuts have been made. The revenue generated by this fee allows Cal Fire to operate as we have in the past. This fee will help prevent further cuts from being made to the department’s budget. For us, we’re expecting about $50 million.”

With a $90 fee, revenues would not reach the desired $50 million.

Between August and November, Brown made four new appointments to the state Board of Forestry, all Demo-crats, who then took a new vote on what the fee could be Nov. 9. The fee ceiling was raised back to $150 in a 6-2 vote.

After the vote, Brown dodged questions asking whether he had “stacked” the board to get his desired result.

“There is a $35 discount for those who are within the boundaries of a local agency providing fire protection, which is actually about 90 percent of the state,” Berlant said, which means that most people will be paying $115.

Many rural residents already pay fees for special fire protection districts, a local example being those living in the West Point Fire Protection District.

District voters overwhelmingly approved Measure A Nov. 8, which charges property owners an annual fee of $78.50 to fund a full-time fire department. Even with the $35 exemption, West Point residents within the SRA would be paying $193.50 in fees for fire protection annually.

“The only consistent thing I heard was, ‘I don’t’ want to pay for Measure A if the state is going to charge us also,’” Carroll said. “That was the only real opposition. People said, ‘I don’t want to pay twice up here.’”

Gary Smith, who works at West Point Lumber, said that most everybody he’s talked to doesn’t seem to like the new fee.

“It’s just another tax,” he said. “We don’t have a say in it. Where’s it going to stop?”

Berlant emphasized that nothing is finalized.

“It’s important to note that this is still the beginning of this process,” he said. “(The emergency regulation) is only in effect for 180 days. After that, the board will have to adopt a permanent regulation. That includes a 45-day public-notice period to give public comment. This is not over yet.”

Sierra Pacific Industries, the largest landowner in Calaveras, and other similar companies have not been asked to contribute to this new fee.

The fee is per structure on parcels. To determine whether a property is within the impacted area, log on to bof.fire.ca.gov and click the State Responsibility Area Viewer link.

‘Empire of the Beetle’: Reflections on the Kenai spruce bark beetle outbreak

11 November 2011

published by www.peninsulaclarion.com

Canada — When the spruce bark beetle outbreak hit Homer in the mid-1990s, I spent my weekends felling trees, cutting firewood and burning slash. My wife and I lived in a thick old-growth Sitka spruce forest, with no view of Kachemak Bay and hidden from the road. As the trees came down, our land became what realtors gleefully called an “emerging view” property. When a 160-acre clearcut appeared below us, our view of the Bay improved dramatically but cold day breezes meant the end of shorts on sunny summer days, and we found ourselves in full view from a noisy road. We loved our Sitka spruce and underlying thick moss, and it was heart wrenching to see it turned into a grass-filled stump farm.

Those troubled memories vividly resurfaced when I read Canadian journalist Andrew Nikiforuk’s “”Empire of the Beetle”: How Human Folly and a Tiny Bug are Killing North America’s Great Forests” (Greystone Books, 2011). I couldn’t have known it in the 1990s, but the Kenai outbreak was only the opening wave of a tsunami that has since swept British Columbia and most of the western United States, fueled by a rapidly warming climate. The mountain pine beetle (Dendroctonus ponderosae) has been the primary culprit further south, targeting lodgepole, ponderosa, and whitebark pines, with our spruce bark beetle (D. rufipennis) being a relatively minor player. Similarly, the pinyon engraver beetle (Ips confusus) has stripped the pinyon pine from pinyon-juniper forests in the Southwest.

As an ecologist at the Kenai National Wildlife Refuge in the 1990s, I had an insider’s vantage point on the spruce bark beetle outbreak in Southcentral Alaska. As the Kenai forests turned red, I and my colleagues wondered if the magnitude of this outbreak was unprecedented. There had been a modest beetle kill in the 1970s on the northern peninsula, but it was peanuts compared to what was now happening. Using tree-ring methodology, we discovered growth releases in the 1810s, 1870s, 1910s, and 1970s throughout the peninsula and across Cook Inlet, indicating that beetles have long been major players in our forests.

The Kenai was the initial epicenter of the present North American outbreak, and Nikiforuk begins his odyssey with an account of “The Alaska Storm.” He spent four years researching this book, which included an extensive review of more than a hundred years of bark beetle studies in the U.S., Canada and Scandinavia, as well as spending time in Canadian logging communities and traveling in the field with some of the top bark beetle experts.

“Empire of the Beetle” tells lots of interesting stories about bark beetle life, and the lives of the people who have studied them or been impacted by them. I found especially fascinating his description of the beetles as “buses” carrying fungi, mites, nematodes, yeasts and bacteria. Each beetle is a mini-ecosystem. Adult beetles, for example, carry fungi that release nitrogen from the wood, which larvae require because they can’t live on the sugar-rich inner bark (phloem) alone.

The real message of this book, however, is the human response to the beetles. Ecologists have long noted that the human response to most natural disturbances is usually much worse than the disturbance itself. The bark beetle story is an extreme example of this proposition.

Lower-48 reporters often asked me about the ecological consequences of the Kenai outbreak. They expected stories of starving moose, massive forest fires and homeless songbirds. I told them instead that the most important consequences were logging, new roads and land subdivision. When the trees died, most private landowners on the Kenai logged their forests, seeking to salvage what little value remained. Logging usually required new roads, thereby improving the land for building (especially if the new view was attractive). Dense, roadless forests that wouldn’t have been subdivided for decades were suddenly ready for subdivision and sales.

Reading Nikiforuk’s book I feel that the Kenai got off very lightly compared to British Columbia in the logging aspect. In BC, most of the land is owned by the Crown. The BC Forest Service essentially gave loggers carte blanche to clearcut everything saleable, dead or alive, with few environmental restrictions. Some clearcuts exceeded 250,000 acres. Green pines were harvested in anticipation of beetle attack, and unaffected species like fir, balsam and spruce were also swept up in this frantic “gold rush” during the early 2000s. But the boom is winding down now and communities have lots of unemployed loggers, even as BC has spent more than a billion dollars repairing road damage caused by heavy logging trucks.

What lessons can be learned from all this? Except for a cold winter, Nikiforuk shows that a bark beetle outbreak cannot be stopped by logging, spraying, electrocution, burning, or explosives once it has gotten under way. Nevertheless, the public and politicians feel the need “to do something” about the problem, even if the cure is worse than the disease.

The second lesson is that unselective logging can intensify and prolong a beetle outbreak by leaving slash which breeds more beetles. Trees on clearcut perimeters typically are blown down and provide the best possible beetle nurseries. Slash and bucked up logs left along the Bradley Lake powerline in the late 1980s probably helped spread the outbreak at the head of Kachemak Bay.

The third lesson is that massive fires did not follow beetle kill in either Colorado or Alaska. Beetle-killed spruce does indeed burn, especially in the first-year red-needle stage, but drought-stressed live trees with dry needles burn even better. The rate of spread of most fires on the Kenai is determined by ground fuel moisture in litter or grass, and not by tree crowns, whether dead or alive. Dry weather, especially in the spring, is the chief fire danger.

The fourth lesson is that diverse forests are the best guarantee of healthy forests in the future. BC forests were mostly even-aged, post-fire stands that had been protected with years of fire suppression. The southern Kenai forests were also quite homogeneous with a long fire cycle of 400-600 years, historically protected by a cool and moist climate. In both cases these forests were loaded guns, waiting for a trigger to be pulled. The trigger was climate warming. In BC, prior to the 1980s, cold winters often reached the lethal temperature of minus 40 degrees Fahrenheit, which kills beetle larvae. Once winters warmed up, beetle populations exploded. On the Kenai, winters of that severity rarely occur and aren’t a limiting factor; it was consecutive warm summers that pulled the trigger. An unprecedented 11-year run of warm summers from 1987 to 1997 allowed beetle populations to increase exponentially until they simply ate themselves out of house and home.

What should we do with logged land, if anything? I wish that Nikiforuk had addressed this conundrum. It is certainly on the minds of Kenai landowners. In my opinion, the best response is to do nothing. Planting white, Sitka or Lutz spruce is pointless because they will be susceptible to beetle kill with warming summers. Planted spruce could be harvested for pulp in 40-50 years, but I expect beetles will hammer these trees when their diameters reach 6-8 inches. Some landowners have successfully planted lodgepole pine, but it is only a matter of time before mountain pine beetles arrive from northern BC. Monoculture stands of lodgepole pine provide poor wildlife habitat and require fire to open their pitch-sealed (serotinus) cones for reproduction. Siberian larch also grows here, but it is susceptible to moose and hare browsing, and to larch sawfly, and it is expected to do poorly with warmer summers. Birch and aspen are nice in the yard, but they require fences or wire mesh to keep the moose off. From either an economic or ecological point of view, there appears to be no tree species worth planting on the Kenai on a large scale.

Cutover grasslands on the Kenai will eventually burn, as some have already done. If they burn late in the season, which we expect with warmer and drier summers, exposed mineral soil will provide a good seedbed for both spruce and hardwood germination. In beetle-killed forests that haven’t been logged, the trees are falling down and rotting, becoming nurse wood for the next generation of trees.

The Canadian experience, as chronicled by Nikiforuk, makes a strong case that the best defense against massive insect outbreaks and large forest fires is to have a diverse landscape with a variety of stand ages and tree composition. The central and northern Kenai forests have this diversity because of the short fire cycle of 130 years in upland mixed white spruce and hardwoods, and 80 years in lowland black spruce. The southern Kenai could well achieve similar diversity because new forests will be recruited very unevenly if we wait for fire and nurse wood to do their natural work at their own pace.

In British Columbia there is great political pressure to reforest cutover Crown lands. Forestry is big business in BC, but it should be approached with great care and with an eye to the future. To simply replant monoculture crops of pine and spruce will create a mosaic of even-aged stands that serve as beetle fodder in a warming climate. A safer approach is to plant a variety of species, both softwoods and hardwood, on the same plots so as to mimic a natural forest. Forest pests like bark beetles, defoliators or blight can take out one tree species but not the whole stand. Foresters are developing poly-crop methods in the tropics and these methods certainly deserve study in our northern forests.

Drought chokes shipping, sparks forest fire

22 November 2011

Germany — Prolonged dry weather is disrupting shipping on some of Germany’s main waterways, the Rhine and Elbe rivers. The drought has also sparked a forest fire in Upper Bavaria.

The current water level of the Rhine is averaging 1.5 metres below average. And in Kaub, Rhineland-Palatinate, the river is flowing at a depth of a mere 56 centimetres, the lowest it has been all year.

Ralf Schäfer of the Waterways and Shipping Office for Bingen confirmed that this already low level is predicted to drop another five centimetres by the end of the week.

“It’s too difficult for ships to move in such low waters. Businesses are being damaged, companies are having to load 4,000 tonne capacity ships with a mere 1,000 tons of goods,” Schäfer said.

Many barges along the Rhine are stuck, with some ferry services being cancelled since Saturday.

“You can see every single stone on the riverbed,” said Susanne Maul of the Rhine-based ferry company Rheinfähre Maul.

Across the northeast of the country, the Elbe River, which flows from Cuxhaven on the North Sea to the Czech Republic, is also suffering from the extreme lack of rain.

In Dresden, where the water level averages 2.4 metres high during the winter months, levels of 84 centimetres were reported on Tuesday. This is just over half a metre above the all time low of 26 centimetres recorded in 1948.

Water levels in neither the Elbe nor the Rhine are predicted to rise unless the country is hit by continuous heavy rainfall, but meteorologists are now predicting the driest November since recording began.

This lengthy dry spell also helped spark a forest fire in Upper Bavaria, which started on Sunday afternoon on the south side of the Schwarzberg mountain, near Lenggries.

The flames soon reached several metres in height and quickly spread over an area of eight hectares, roughly the size of eight football pitches.

No-one was injured, and 150 firefighters along with 30 fire engines were dispatched to the scene.

Their initial efforts failed, however, to bring the inferno under control due to the dark conditions. Four helicopters were sent to dump water on the area which brought the fire under control late on Monday.

Police are using thermal imaging cameras to check for any remaining embers.

The cause of the fire is not yet known, but catastrophe expert Alexander Bauer of the Bad Tölz-Wolfratshausen authorities told public broadcaster Bayerischer Rundfunk the dry weather had aggravated the blaze.
