Climate change talk inappropriate: premier

  Climate change talk inappropriate: premier NSW Premier Gladys Berejiklian says questions about the links between climate change and the state's unprecedented bushfires are 'inappropriate'.With firefighters continuing the battle to save lives and homes, now is not the time to be talking about the impact of climate change, NSW Premier Gladys Berejiklian insists.

The next frontier for the wealthy tourist dollar has environmentalists concerned.

Are we doomed ? If you’re an expert in climate science, you probably get this question a lot. “I do,” said Kate Marvel, associate research scientist at the NASA Goddard Institute for Space Studies. But if we can hold the global temperature increase to 1.5 degrees Celsius, Arctic sea ice is far likelier to

Space travel is predicted to be the next frontier for the wealthy tourist dollar, but there are fears it could also be devastating for the planet.

A single trip aboard a SpaceX Falcon rocket has about the same carbon footprint as flying across the Atlantic 395 times, according to analysis by travel website Champion Traveler. That's equivalent to the average output of 73 cars over an entire year.

"These emissions represent a tiny fraction of the human race's yearly CO2 output," the site said in a recent post.

'Australia must stop selling coal': Branson calls for climate 'revolution'

  'Australia must stop selling coal': Branson calls for climate 'revolution' As 'unprecedented' bushfires threaten NSW, Sir Richard Branson has a plan for Australia to become a world leader in the renewable energy space. English billionaire Sir Richard Branson has called on Australia to become a world leader in the renewable energy space, saying that "if you do the right thing, you'll find in the years to come you'll get the benefits". As NSW braces itself for one of the worst days of bushfires ever recorded, the Virgin Group founder spoke about its connection to climate change on Tuesday morning in Sydney.

Unemployment, crime, immigration seem closer to me and hence I give the climate threat a lower priority than those things that feel nearer. If we say the Earth is now going to hell, we're going to a boiling Earth, a hothouse, and you keep saying that, it activates a barrier we call the doom barrier.

"But... 1000s of rockets per month carrying scientific or governmental payloads as well as a steady stream of space tourists - the environmental impact will be much greater."

At the moment, SpaceX - run by eccentric tech guru Elon Musk - sends a couple of dozen flights to space a year, but plans to ramp that up dramatically. And SpaceX isn't the only company hoping to cash in on space tourism, with Richard Branson's Virgin Galactic and Jeff Bezos' Blue Origin at various stages of development.

"This reporting is not meant as a nay-say on rocket launches or space travel in general," Champion Traveler said.

"But as rocket launches become more common and space tourism accelerates... companies such as SpaceX will need to consider the environmental impact of their launches at scale."

Greens senator calls opponents 'arsonists'

  Greens senator calls opponents 'arsonists' Greens senator Jordon Steele-John has refused to back away from calling Labor and coalition senators 'arsonists' during a fierce spray on climate action. A Greens senator has branded major party politicians "arsonists" in an incendiary spray on climate policy as catastrophic fire conditions grip NSW. An enraged Jordon Steele-John, who represents Western Australia, let rip in the Senate on Tuesday during debate on the federal government's proposed laws cracking down on energy companies.

15. Doom Tourism Locations • Similar to Dark Tourism , there are Doom Tourism Locations all over the world. • Here are a few of the more famous Doom Tourism locations There is no better proof that the planet is in trouble than the Doom Tourism sites themselves, but we can make a difference. •

Space tourism will take-off in 2018. As the race between spaceflight companies Virgin Galactic and SpaceX heats up, those who can afford it will be able to

Musk has predicted it would take 1000 rockets to transport enough crew and cargo to set up a viable colony on Mars.

The aviation industry presently dumps about 900 million tonnes of carbon dioxide into the atmosphere every year. Each litre of gasoline burned produces about 2.3kg of carbon dioxide - each atom of carbon in the fuel combining with two oxygen atoms from the atmosphere (hence the scientific notation CO2).

New York-based environmental news site Treehugger pointed out 395 is the capacity of a Boeing 777-300, so really a single Falcon launch was only about as environmentally damaging as a single flight across the Atlantic, if the plane is full - "and they do this hundreds of times a day".

"The people who can afford these flights will all be billionaires... it is a lot more important to worry about the impact of [their] stupid private jets than it is to worry about rockets," wrote Lloyd Alter.

Climate change 'didn't cause these bushfires', climate activism 'is making them worse'

  Climate change 'didn't cause these bushfires', climate activism 'is making them worse' Sky News host Peta Credlin says "so-called experts" have been forced to admit "climate change isn't the cause of these bushfires" but argues "two decades of climate change activism is making them worse".Ms Credlin asked, "If you were inclined to believe the activists, what's your explanation for all the other bushfire catastrophes of the past hundred years or more - starting with the Black Thursday bushfire in Victoria way back in 1851?"

But its sudden collapse would doom the planet. By Katie LanginJan. If the world took up a stratospheric aerosol project, the only way to avoid disaster, wrote Gavin Schmidt, a climate scientist at the NASA Goddard Institute for Space Studies in New York City, would be to have a permanent

Space tourism could have major consequences for Earth’s climate . New computer simulations suggest soot emitted by the rockets could raise temperatures at the poles, significantly reducing seasonal ice cover there, but uncertainty remains about the assumptions used in the study.

A study earlier this year found contrails - the watery trails left behind by planes in the cool upper atmosphere - are actually worse for the climate than carbon emissions, trapping in more heat than they reflect back into space.

'Climate alarmists don't want to look at history' .
Sky News host Chris Kenny says “the trouble with climate alarmists and green activists is they don't want to look at history”.“Yes the smoke is bad, the bushfires are terrible, but for perspective it is always good to look at history, to look at facts,” he said.
