Climate cataclysms set stage for key UN science report

  Climate cataclysms set stage for key UN science report On the heels of jaw-dropping heat and flooding across three continents, nearly 200 nations gather Monday to validate a critical UN climate science report 100 days ahead of a political summit charged with keeping Earth liveable. The world is a different place than in 2014, when the UN's Intergovernmental Panel on Climate Change (IPCC) issued its fifth comprehensive assessment of global heating, past and future. Lingering doubts that warming was gathering pace or almost entirely human in origin, along with the falsely reassuring notion that climate impacts are tomorrow's problem, have since evaporated in the haze of record heat, wildfires and crippling droughts.

Demand for firewood has skyrocketed this winter as temperatures drop below 0 degrees Celsius. While wood fires are more environmentally friendly than gas heaters, they still contribute to climate change. But the increase in wood fires and burning of improper wood is contributing to air pollution, and causing health problems for some Canberrans . Between now and 2045, the ACT government is phasing out gas in favour of electricity, and residents are being actively encouraged through rebate schemes to give up their wood - fired heaters. But it seems Canberrans are not heeding the calls.

Tensions have been running high on the streets of Paris on Saturday, as scores of people rallied against the government’s plan to demand a special Covid-19 health certificate to let people engage in everyday activities. At some points, the situation apparently spiraled out of control as the law enforcement officers were seen using water cannons and tear gas against the angry crowds pelting the police with what appears to be stones and bottles. A group of retreating police officers also saw some of their colleagues falling over a barricade made of burning dust bins.

As water freezes in toilet bowls and ice is scraped from car windows, there is no denying that keeping houses warm is serious business in Canberra.

Between now and 2045, the ACT government is phasing out gas in favour of electricity, and residents are being actively encouraged through rebate schemes to give up their wood-fired heaters.

But it seems Canberrans are not heeding the calls. With months of cold weather still to come, firewood is in short supply in Canberra, and fireplace sales have increased as much as 12 per cent in the past financial year.

For asthmatics and environmentalists, the uptake of wood fires and increased level of smoke in the atmosphere is of concern.

Traffic congestion Canberra 'hasn't seen in its history': Up to four years of disruptions expected for next stage of light rail

  Traffic congestion Canberra 'hasn't seen in its history': Up to four years of disruptions expected for next stage of light rail The next stage of Canberra's light rail is set to create more traffic on the capital's roads, take longer and cost more than the last. Preliminary works for stage 2A will begin in a few weeks and will take an estimated four years to complete.ACT Transport Minister Chris Steel today confirmed that stage 2A of the light rail project would likely be much more disruptive than stage 1, saying it would cause traffic congestion never before experienced in Canberra.

“We can buy plenty of wood . It’s doing the work to get it to the customer.” Debbie Potter, owner of Readfield-based Potter Family Firewood , said Friday that her business is done selling wood for the season – that’s weeks sooner than usual, as they typically stop in November. Allen’s firm sells about 1,500 cords in a year. Demand comes from a 30-mile radius from his Maple Street business. He said he sells about 70 percent of his annual product from September to November, when people are stocking up at the last minute before winter begins. “We tell them every year to get it in July and August,” he

Regular fire , i.e. wood or paper burning - no. Because there isn’ t enough oxygen to start or sustain regular combustion. But there are kinds of combustion which work underwater. For immiscible liquids like oil and water or even petrol and water, the oil, being lighter floats on top. Being exposed to atmosphere, there is a chance for it to vaporize under right conditions and form a burnable mixture. And since there is no water over the oil surface, the flame keeps burning on top of the water.

But, the wood fire industry maintains there is a sustainable way forward with better education and tighter rules around wood supply.

Demand for firewood on the rise

Peter Dimmock has been selling firewood in Canberra for more than 30 years. This winter, he can not keep up with demand.

"Our stocks are very low," he said.

"We're at about 10 per cent."

Mr Dimmock said that was due, in part, to delays getting stock out of Queensland, thanks to wet weather and border closures.

But he said there was also a growing demand for wood heaters, even from those who previously accessed the rebate scheme to move toward alternatives.

"A lot of customers are telling me they took up the rebate, and they weren't happy with heat coming from gas and electricity and weren't happy with the cost of gas and electricity over firewood, and some people have actually gone back to putting wood fires in their homes," Mr Dimmock said.

"We have very limited supply and were actually in a situation last week where we had to close the doors because we literally couldn' t get redgum in." Ms Papageorge said it was a similar situation across other Adelaide Hills and city woodyards, with seasoned redgum supplies from the New South Wales "With this increased demand the mills are not able to split the wood quick enough to meet the demand that everybody needs. "Customers will have to accept the fact they will have to look at alternative wood for their firewood for the rest of the season." Many people working from home have been burning

Hundreds of people have died amid the rising temperatures, including in British Columbia, which has registered 486 deaths in the past five days, compared to its usual 165 fatalities at this time of year. The province’s wildfire service said it had responded to the blaze in Lytton and confirmed on Thursday that there were four general clusters of multiple wildfires across British Columbia. “Ground crews, helicopters, air tankers, members from volunteer fire departments, and heavy equipment have responded and will continue to do so over the coming days,” it said in a statement.

It is a similar story at fireplace retailers.

"We've found this year, at the end of this financial year, wood fire [sales] are up about 12 per cent," manager of Fyshwick Home and Heating Lewis Gonzalez said.

He said modern fireplaces were significantly more sustainable than their predecessors, and that using the right wood reduced the level of smoke released into the atmosphere.

Both Mr Gonzalez and Mr Dimmock said the burning of green wood was an ongoing issue and there were calls for stricter policing of those who sell the low-quality product, which both causes more pollution and does not burn as hot or as long as untreated wood.

"If you burn wood that is seasoned well, you don't actually get much smoke," Mr Dimmock said.

The science behind wood fires

Director of the ANU's Institute for Climate, Energy & Disaster Solutions Mark Howden said that while wood fires were better than gas heaters, they still contributed to climate change.

 Autumn / Winter 2021: These are the most important fashion trends for the upcoming season The handle to knit sweater, wool coat and leather booties still takes a little bit, yet we are already looking forward to us in autumn / winter fashionable. Because in the colder season we just have much more opportunities to create ourselves to styling and cool layering looks. That's why we'll take a look at the five largest fashion trends , which expect us in autumn / winter 2021.

Burning driftwood, oleander, or painted or treated wood can release toxic or harmful chemicals into the air. Soft wood , green wood , and big wood will produce substandard fires . Burning non-local wood or endangered timber poses an environmental hazard. Doing so can release toxic or harmful chemicals into the air, according to the Environmental Protection Agency. But even when choosing between two logs, there are greener (and less green) options out there. Here are some tips on firewood NOT to buy.

One advantage could be keeping away pests and stinging insects for a spell, but it’s best to get a fire going using kindling and lower branches from dead-standing trees (they will make a satisfying and crisp ‘SNAP’ sound when being broken off the In a campfire or open fire , once the fire is established, burning wet wood can increase the available heat for cooking or for personal warmth. The steam from the wet wood will transfer heat in addition to the radiant heat from the fire .

"When we take wood from a forest and then burn it, we transfer the carbon in the forest into the atmosphere, so we add to climate change and there are other greenhouse gases like nitrous oxide in the smoke," he said.

He also noted that in the ACT, where electricity is effectively 100 per cent renewable, burning wood fires released carbon that would otherwise be avoided through electric heating.

"If you're in Canberra you're actually on an electric heating system which uses renewable electricity ... you haven't got that same substitution effect of replacing fossil fuels," he said.

"[But] it's a lower-emissions option than a natural gas heating system, so it's definitely better than if you've got a gas system — but I wouldn't give it a net-zero type framing."

Asthmatics seal themselves in

Weston Creek resident Michelle Weston is one of many asthmatics worried about air quality.

She said she had particularly struggled this winter as wood heaters fired up.

"I couldn't reliably open a window for fresh air, I couldn't sleep, the air was really thick with smoke inside, I couldn't use my clothesline and air dry my clothes," she said.

Australia's cold, wet winter isn't threatening any records, Bureau of Meteorology says

  Australia's cold, wet winter isn't threatening any records, Bureau of Meteorology says It may feel like one round after another of wet, cold and windy weather, but the data suggests we are just not as used to it as we once were.It feels like it has been one icy blast of wet and wild conditions after another this winter, but is it really that cold and wet or have we just been spoiled by so many mild winters?

"I even blocked my chimney off, and I can't use my gas heater because the smoke comes through."

"People are being deprived of the fresh air in their homes, in the place where they live," she said.

The geographical characteristics of Canberra mean if smoke settles on a clear night, it will not be blown away.

In fact, for weeks during the Black Summer fires, the national capital had the world's worst air quality among all cities that publish records.

The ACT government said, for this reason, there are a number of suburbs where wood fires are prohibited.

But Ms Weston does not live in one of those areas.

"It is a helpless feeling," she said.

"I like this suburb, this area, it's a great place to live, but I have no choice about what's being pumped out at me."

ACT Environment Minister Rebecca Vassarotti said there was currently no plan to crack down on the use of wood fire heaters.

"We are encouraging people to look at different ways of heating their home, particularly recognising that wood fire smoke does have health and environmental impacts," Ms Vassarotti said.
