We always hear about the doom and gloom...why not the 10's of thousands of new species recently discovered?

Oh that's right, it doesn't fit the agenda.

So... do we blame climate change... or outdated cannabis laws?

Climate change, of course.

Man charged with lighting an out-of-control NSW fire to protect a cannabis crop

A 51-year-old man has been charged with lighting an out-of-control fire in the NSW Northern Tablelands in order to protect a cannabis crop.

The fast-moving blaze at Guyra Rd in Ebor, northeast of Armidale, was burning across more than 2000ha on Friday afternoon as it spread towards the Ebor township.

"...This is climate changed. We’re in the worst drought recorded. A million hectares of bush has burned. Barnaby says it’s Greens voters and the sun’s magnetic field....Pray for rain. Pray harder for leadership..."

Only a few pollies, the extreme right and a few .....'s on Nicks think the issues has to do with the Greens or deny the the role of climate change in these fires

Lies... The worst drought in Australian history was the 'Federation Drought' 1895-1903.

Historical accounts and scientific analysis indicate that South-Eastern Australia experienced 27 drought years between 1788 and 1860, and at least 10 major droughts between 1860 and 2000.

The worst fire in Australian history was in 1851 when 5 million hectares of bush land burned

The Black Thursday bushfires, were caused in part by an intense drought that occurred throughout 1850 when the continent suffered from extreme heat. On 6 February 1851, a strong furnace-like wind came down from the north and gained power and speed as the hours passed. It is believed that the disaster began in Plenty Ranges when a couple of bullock drivers left logs burning unattended, which set fire to long, dry grass affected by the recent drought. The year preceding the fires was exceptionally hot and dry and this trend continued into 1851.

Intense bushfires are not uncommon in southern Australia. The region is one of the three most fire-prone in the world. Within the last two hundred years, the area has experienced and documented at least twenty-five major fires, beginning with Black Thursday in 1851. The intensity of these fires is due in part to natural fuels, such as sclerophyll forests in the region. While adapting to cope with drought and predators, the trees’ leaves turn into prime fuel for fires. They become tough as protection from dry conditions and to increase the efficiency of nutrient use. They also develop tough spikes and chemicals to protect themselves from small animals. The leaves’ tough surface allows them to last longer and build up on the forest floor and the chemical makes them flammable.. The abundance of flammable fuel can cause an inferno with a single spark


The primary cause of catastrophic bush fires during this period lies in a poor understanding of local fire regimes and in inappropriate landscape management by settlers. Aboriginal people had managed these areas for tens of thousands of years, using fire-stick farming to clear out fuel build up and maintain tracts of walkable land and hunting grounds. Their displacement by Europeans meant a complete regime shift in the ecology of the Australian bush with the result that tremendous fires become possible.
... nah, had to be Climate Change

Methinks the lady doth protest too much.

Skids, this isn’t especially difficult. Climate change sets the conditions and then different causes start the fire. There isn’t anything particularly challenging here.

You obviously didn't read my post... look, read this bit....

It's not really difficult.

The amount of flammable material in a park is referred to as the fuel load. How much fuel builds up in a given area depends on how much the local vegetation 'sheds' dead fine fuel litter and how quickly it rots.

We measure the amount of fuel available to burn to determine the overall fuel hazard in our parks. The greater the fuel load, the higher risk of bushfire. The overall fuel hazard is rated from low to moderate, high, very high and extreme.

The overall fuel hazard is measured by assessing the hazard posed by:

the type of bark on trees
the amount of ‘elevated’ fuel such as grasses, ferns and shrubs
the amount of fine fuel on the surface of the ground.
Research into fuel accumulation and rotting rates of different plant communities is used to develop fuel accumulation models. Fuel accumulation models are used when planning hazard reduction burns. We invest in research and development to help better manage bushfire risk and conserve biodiversity.

From a couple of blokes and some sheilas on the ground at the CSIRO:

"Changes to the climate system have occurred and are likely to continue

The international scientific community accepts that increases in greenhouse gases due to human activity have been the dominant cause of observed global warming since the mid-20th century. Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system.

Australia's changing climate represents a significant challenge to individuals, communities, governments, businesses, industry and the environment. Australia has already experienced increases in average temperatures over the past 60 years, with more frequent hot weather, fewer cold days, shifting rainfall patterns and rising sea levels. More of the same is expected in the future."
....

"Research has shown that most of the changes observed over recent decades will continue into the future. Projections suggest that for Australia:

- hot days will become more frequent and hotter (very high confidence)
- sea levels will rise (very high confidence)
- oceans will become more acidic (very high confidence)
- snow depths will decline (very high confidence)
- extreme rainfall events will become more intense (high confidence).

Seasonal-average rainfall changes will vary across Australia.

In southern mainland Australia, winter and spring rainfall is projected to decrease (high confidence), but increases are projected for Tasmania in winter (medium confidence).

In eastern Australia, there is high confidence that in the near future (2030) natural variability will predominate over trends caused by greenhouse gas emissions. This means that while the trend is skewing the natural variability towards winter decreases, it will be relatively minor compared to the natural seasonal and annual changes, so continuing to manage for large natural variability will still be appropriate. For late in the century (2090), there is medium confidence in a winter rainfall decrease.

In northern Australia and northern inland areas, there is high confidence that in the near future (2030), natural variability will predominate over trends due to greenhouse gas emissions. There is low confidence in the direction of future rainfall change by late in the century (2090), but substantial changes to wet-season and annual rainfall cannot be ruled out.

The time in drought is projected to increase over southern Australia (high confidence).

....

Southern and eastern Australia are projected to experience harsher fire weather (high confidence)."

I'm surprised the climate extremists haven't mentioned the Venice floods.

I mean, rising sea levels should have swallowed the island city up by now shouldn't they? Even though the recent surge was well short of the heights reached in 1966.

Maybe it's because the city is 'sinking' 1-2mm/year that has kept the issue quiet. Which will go first? The Maldives (Which should have disappeared already going by projections from 30 years ago) or Venice?

Look, climate change is a slow process in human terms.

Any changes to our climate in Australia at the moment are infinitesimal, but if China and India keep pumping out CO2 like they do kids, it's going to get hotter and drier.

Therefore rather than just throwing the hands up and saying "climate changed caused the bushfires" (which is like saying summer caused them, and we get summer each year), we need to do something about the vast tracts of land purpose designed to be burnt which more and more people are living near.

Every state government should be putting more resources into forestry management not less but apparently if you say that you're a Murdoch media stooge.

What is the point that you think should be addressed and never is, Skids? It's not evident from the irrelevant things you post.
