Maintaining a fireplace in the backyard

Thursday, July 30th, 2009

Outdoor fireplaces are similar to indoor fireplaces and have stone or brick patio. Traditionally, like all fireplaces, even the outdoor ones were wood burning but these days, due to pollution and its energy efficient capabilities, or rather lack of it, has people moving towards gas. Even outdoor fireplaces require regular cleaning to maintain it.

Outdoor fireplaces using gas are quite popular these days as they provide immediate warmth, very similar to wood. Gas logs sets are used instead of wood in gas fireplaces. Gas logs are ceramic fibers which resembles wood. These use natural gas or propane for burning; as a result they do not produce carbon monoxide and also do not leave ashes. Vent free gas logs are always advisable for use.

Like for indoor fireplaces, even outdoor fireplaces will require few essential accessories. Depending on the budget, one can buy a range of fireplace accessories. Like a fireplace tool sets is very essential which contains a shovel, tongs, brush and poker. Fireplace screen, another important item prevents the sparks from leaving the fireplace and also prevents pets and children from coming in contact from fire. But these screens are useful in wood fireplaces and not in electric and gas fireplaces.

Soot reduction slows global warming

Monday, January 5th, 2009

Nasa scientists have said that global warming can be slowed dramatically by slashing emissions of soot.

According to a study by the space agency, cutting down on the pollutant, can have an immediate cooling effect – and thus prevent hundreds of thousands of deaths from air pollution at the same time, reports the Independent.

The study has been published in the journal Atmospheric Chemistry and Physics.

The study, from Nasa’’s Goddard Institute for Space Studies, has concluded that tackling the pollution provides “substantial benefits for air quality while simultaneously contributing to climate change mitigation” and “may present a unique opportunity to engage parties and nations not yet fully committed to climate change mitigation for its own sake.”

Black carbon, the component of soot that gives it its colour, is thought to be the second largest cause of global warming after carbon dioxide.

Government declares beluga whale endangered

Monday, October 20th, 2008

The beluga whales of Alaska’s Cook Inlet are endangered and require additional protection to survive, the government declared on Friday, contradicting Governor Sarah Palin who has questioned whether the distinctive white whales are actually declining.

It was the Republican vice presidential candidate’s second environmental slap from Washington this year. She has asked federal courts to overturn an Interior Department decision declaring polar bears threatened under the Endangered Species Act.

The government on Friday put a portion of the whales on the endangered list, rejecting Palin’s argument that it lacked scientific evidence to do so. The National Oceanic and Atmospheric Administration said that a decade-long recovery program had failed to ensure the whales’ survival.

“In spite of protections already in place, Cook Inlet beluga whales are not recovering,” said James Balsiger, NOAA acting assistant administrator.

The decision means that before federal agencies can issue a variety of commercial permits, they must first consult with the National Marine Fisheries Service to determine if there are potential harmful effects on the whales.

That has the potential to affect major Alaska projects including an expansion of the Port of Anchorage, additional offshore oil and gas drilling, a proposed USD 600 million bridge connecting Anchorage to Palin’s hometown of Wasilla and a massive coal mine 45 miles south of Anchorage.

The state does have serious concerns about the low population of beluga whales in Cook Inlet and has had those concerns for many years, Palin said in a statement. “However, we believe that this endangered listing is premature,” she said.

Palin in April successfully lobbied for a six-month delay in a listing decision until a count of the whales this summer could be included in deliberations. That count showed no increase over 2007 numbers — 375 whales, compared with a high of 653 in 1995.

Federal regulators and conservation groups said further delay would be harmful.

NOAA said Friday the Cook Inlet population declined by 50 percent between 1994 and 1998 and “is still not recovering” despite restrictions on the number of whales that Alaska’s native population can kill for subsistence. It said recovery has been hindered by development and a range of economic and industrial activities including those related to oil and gas exploration.

The National Marine Fisheries Service “will identify habitat essential for the conservation of the Cook Inlet belugas in a separate rule-making within a year,” the agency said.

The federal decision pleased environmentalists.

“We can finally focus now not on whether the belugas are endangered, but what we can do to protect them,” said Brendan Cummings, an attorney for the Centre for Biological Diversity, one of the groups that petitioned for the listing.

Cook Inlet stretches 180 miles from the Gulf of Alaska to Anchorage. It is named for Capt James Cook, the British explorer who sailed into the inlet in 1778 on a quest to find the Northwest Passage.

Beluga whales feed on salmon and smaller fish. They can also eat crab, shrimp, squid and clams. During summers, the whales, which reach a length of up to 15 feet, often can be spotted from the highways leading away from Anchorage, gathered at river mouths, chasing salmon that have schooled before a run to spawning grounds.

Beluga whales’ natural enemies are killer whales, but something else has been keeping their numbers down in Alaska’s Cook Inlet.

Craig Matkin, an independent biologist who has worked in south central Alaska for 25 years, said the delay in the listing had held up a comprehensive research plan to find out why the population had not recovered after subsistence hunting was curtailed.

The concern is not just in numbers, he said, but in distribution. Whales in recent years have been staying in northern Cook Inlet near Anchorage.

“They’re just gone from these areas,” he said of his own home near in Homer, near the tip of the Kenai Peninsula and about 100 miles from Anchorage. “Why they aren’t coming down into this habitat is a question I’d like to answer.”

Future development won’t be helpful to the recovery, Cummings said, starting with the noise and pollution associated with industrialization of the inlet, which includes oil rigs off the Kenai Peninsula.

Global warming, changing ocean conditions and higher temperatures in salmon streams may be another factor, Cummings said.

The Port of Anchorage, helped by congressional earmarks secured by Sen Ted Stevens and Rep. Don Young, has embarked on a USD 500 million project to double the port’s size and replace its aging docks.

Environmental groups also have expressed concern about a planned coal mine 45 miles from Anchorage across Cook Inlet, where developers propose to mine 300 million metric tons of sub-bituminous coal, roughly equal to the energy of a billion barrels of oil, over 25 years. That would mean noise and boat traffic associated with building and operating a mine, a potential effect on salmon streams and more warming.

The Cook Inlet beluga whales are one of five populations in Alaska waters and the only one endangered. Other beluga populations off Alaska inhabit Bristol Bay, the eastern Bering Sea, the eastern Chukchi Sea and the Beaufort Sea.

Marathon men tour a sunny and clear Beijing

Tuesday, August 26th, 2008

A midnight storm ensured clean and clear weather for Olympic host city Beijing on the last day of the Games on Sunday as the men’s marathon got under way through the leafy streets of the city.

But cloudy weather was expected later in the day, the Beijing Meteorological Bureau (www.bjmb.gov.cn) said.

The bureau forecast a high of 30 degrees Celsius (86 degrees Fahrenheit) and a low of 22 C (71.6 F).

Pollution had been a major worry for athletes and organizers ahead of the Games, but the air has been largely clear, thanks in part to occasional heavy rain.

China wrap up a spectacular Olympics on top of the medals table and with a closing extravaganza planned in the Bird’s Nest.

Before that there are another 12 gold medals to contest, including the finals of men’s basketball and volleyball, and six big bouts in the boxing ring.

Traditional highlight of the final day is the marathon, where Kenya will be hoping for their fifth athletics gold.

Vietnam, Cambodia brace for Mekong floods

Wednesday, August 20th, 2008

Rising Mekong floods upstream may cause landslides and deep inundation in Cambodia and southern Vietnam but the seasonal floodwater would also bring farmers good crops of rice and fish, officials said on Tuesday.

The Vietnamese government said rescue forces must be ready to move people from dangerous areas in southern Vietnam, where the Mekong river reaches the South China Sea after traveling more than 4,000 km (2,500 miles) from Tibet through Laos and Cambodia.

Four people have been killed in flooding and landslides in Laos, where the Mekong river has hit its highest level in at least 100 years after several months of unusually heavy rain.

Cambodia has alerted villagers of rising waters and the authorities have prepared 4,000 boats and life-jackets for the vulnerable areas in the eastern provinces of Kampong Cham and Kratie, the national disaster management committee said.

The Mekong River Commission said the river from northern Thailand to central Cambodia was higher than it was in 2000, when the worst floods in four decades struck southern Vietnam.

“Floods in the Cuu Long River Delta happen every year, so people are used to taking preventive measures for crops and life,” Le Van Banh, director of the Mekong Delta-based Rice Institute, told Reuters by telephone from Can Tho city.

“In the past floods caused problem to transportation and it was hard for children to come to school, but in recent years Vietnam has built protective dykes and residential areas above the flood-peaking level,” he said.

Could the extra water caused by global warming cause the globe to change its axis or something??

With added water being free to move about our planet, shorley this will have some affect on the rotation of earth and or the axis of our lovely earth.

The total amount of water is the same, but its distribution can be altered by global warming. Specifically, mass moves from the poles to lower latitudes and this must slightly increase the moments of inertia of the earth. Since angular momentum is conserved, the rotation of the earth will slow and days will be longer. The effect is rather small, a few milliseconds, but easily measured.

http://www.ldeo.columbia.edu/users/jcm/T…

No. GW won’t create any water. It will change some from solid to liquid and some liquid to gaseous and will relocate some but that’s it. And the weight is negligible compared to the mass of the Earth. (Oh, OK, d/dx… is right, due to conservation of angular momentum, moving water from the poles to the equator will have a very miniscule impact).

But there’s some interesting answers already:
“water moving into it’s liquid state would weigh less” - really? Well, there goes the law of conservation of mass (unless ice turning to water involves thermonuclear reactions…)
“the worst it could do is flood the Earth” - nope, the worst it could do is raise sea levels by 80m - lots of land higher than that

Every time I read about animals (besides them dying from global warming), everyone thinks that we must save them. That would be fine if people came out and just said, “we don’t care about natural selection, we think it is always better to have animals even though natural selection doesn’t think so…we don’t care about it.”

Yet people remain so arrogant that it disgusts me. We like cute animals over mean predators, we need to save them even though Ebola is killing them etc. What ever happened to good old natural selection? What if they need to die? Why do people remain such arrogant control freaks that try to control and change a planet that will never be static?

I just don’t get it. Just be honest and say that you don’t give a flip about Darwin and we have to save things from natural selection by OUR natural selection.

Those save the otter people become attached to a cute face and associate its behavior with that of a humun being. In their eye’s an otter fur coat is just like wearing one made of human skin. Watch the movie “Grizzly Man” sometime. Thats a great example of the mental illness these people share. It has a great ending. Mister, name the bears, discovers that the bears see him not as a friend and member of the family, but rather as he is….meat. If you put cute eyes on the ebolia virus these people would start a save the ebolia campaign.

so it’s natural selection that sees me a crippled man who became that way by saving a life, suffer a horrid life living in abject poverty while the crack dealer drives a luxury car, eats in a restaurant, has extravagant parties and gets laid every night? i feel really suicidal now! i mean natural selection means a man intentionally selling poison and raping young girls while prostituting others is more valuable to humankind than i ?

Oh, we’re hardly extinct. We’ve been forced into hiding by the likes of Rotter and other randy old men. But you shouldn’t worry about us, darling, as we’ve found the most splendid Edenic hideaway here. It even has internet.

I agree with Rotter. Though the pollution hasn’t helped. I remember an old Blue Peter episode telling us about how they were also strangled by those plastic six pack lager (some filthy brew the lower orders drink for survival) holder majiggys.

They did a graphic reenactment and everything.

What is going to happen on 12/12/12?

I’ve heard a lot of things and I really wanna know from some who knows their stuff.

I assume that you are referring to the supposed “end of the world” myth that some people believe in because the ancient Mayan calendar ends in 2012.

Our calendar ends on 31st of December every year. What happens when our calendar ends? The answer to that will give you the answer you are looking for.

Even if the Mayans did think that the world was going to end in 2012, what makes people think that they were right? People have been predicting the end of the world for centuries and none of them have been right yet. Remember all the people who thought the world would end on the turn of the millennium? Before that there were people who said the world would end some time in the 1990’s when the planets in our solar system all lined up (they were only very roughly aligned anyway). Before that it was something else and so on and so on, going right back to prehistoric times.

Check out this page for a very comprehensive list of doomsday claims throughout history going right back to 90CE (about 1/2 way down the page under the heading “Hitting the Motherlode”.

——— A lot of people actually believe that nothing happened on 01/01/00.

I had been working on software for a major corporation, and several of our computer systems certainly would have failed on that date, or the next day etc. And our main materials management planning system had started failing a full year earlier, or more. Any system that was heavily date dependent and used a 6 digit date was at risk.

So, yes, we fixed a lot of code over the 2 years leading up to 2000/01/01, and guess what, we had no failures left for that date. It was not because the concern was unfounded, but because we checked code and corrected it, tested it,
We had purchased software allegedly fixed for y2k, and when tested failed. Well that happens with fixed software. people miss problems or even see the problem and do not manage to fix it right.

What will happen on 121212? Well, there is nothing much should happen. But next month we will have a few programs that confuse month and year go belly up because month 13 showed up for the first time. This will now be rare, as most dates are now held in 8 digit format.

But that 8 digit format was not the norm in 1995.

Would energy efficiant street lights be an option to solving the Green house crisis?

I was driving to cronulla the other night and noticed the significant amount of street lights when looking over the edge of the cliff we were on. Then i hatched this amazing idea that would cut heaps of tons of Australia’s annual emissions

It wouldn’t ’solve’ the greenhouse crisis, but it would sure help. If everyone thought like you, maybe we would achieve somthing.

I think street lights have always been energy efficient by design. I used to wonder about the same thing until I found that out. Street lights don’t use conventional incandescent bulbs, they are already efficient (as far as I know).
