People need to be punished for doing things that damage the planet. The only way to do this is by putting tax on such activities. Setting target years to ban fossil fuel burning cars will not work. People need to be enticed to change their ways.

Archaeologists Say Fire Caused Tuberculosis
Fire caused tuberculosis according to new archaeological theory.
Evolution is very powerful. A change in climate leads to the survival of those who suit the new climate more adequately. A series of ice ages meant hairy people with narrow nasal passages (to warm the damaging cold air on it way into the lungs) passed on their genes. People living in central Africa remained in a warm climate, so they did not have to adapt.
It is assumed that TB is mainly a thing of cold climates. More correctly, molecular archaeological evidence shows that TB began in Africa. Just how scientists reached the conclusion that humans passed it on to animals is beyond me, though. This is pie in the sky stuff, mere speculation.
Man has been using fire for at least 200,000 years. This is obvious. Scientists say TB appeared anywhere from 70,000 to 6,000 years ago. Such debate about the correct time of its occurrence means a lot of work has to be done before TB can be linked to fire.

Plant Chemistry Indicates a Very Hot Future
Chemistry: Stomata on plant leaves shows the way to predict climate change.
It looks like the future is going to be very hot - in Asia at least. Oddly it will not get drier. With more carbon around plants will not need as much water, so grass will grow everywhere. A 5 degree rise in temperature is expected by mid-century. High humidity will make life unbearable..
Plants have a significant effect on the climate in general. This has been ignored in the past. Scientists are now examining it. More efficient use of water means less water in the atmosphere which increases temperature during the day. Spring will arrive earlier as the climate itself changes.
A study of stomata, tiny spores on leaves involved in carbon dioxide absorption and the shedding of water, has provided information on how plants affect the weather. It was initially for understanding how plants work, but it has ultimately been applied to the study of climate change.

Science Holds That Australia is Evergreen
Science: Fagus Nothofagus gunnii is Australia's only temperate deciduous tree.
Australia has always been very hot. So hot in fact that only a few deciduous trees ever evolved. True some have been brought from other countries and the trees do grow in the cooler regions of Australia today. However, except for small pockets in the tropics evergreens predominate.
Trees which drop there leaves prefer a fixed unchanging climate. Australia is where the unexpected happens. Like the present where we are having a long hot end to summer and it is unusually wet. Evergreens can adapt and take off when conditions are favorable. When deciduous trees lose there leaves it could rain heavily, but they can no longer absorb the moisture. Conversely, putting out leaves when it dry for months on end is totally ineffective. Hold onto your leaves is the moto. When it rains evergreens are ready to push on to further growth.
Australia has one lonely temperate deciduous tree. And wouldn't you know it, the tree only grows in Tasmania, which gets the icy wind from Antarctica. These winds are always there in winter so the deciduous beech or Fagus ("Nothofagus gunnii") puts on a fabulous autumn leaf display then goes dormant during winter.

Australia's Bird the Emu
Early European settlers were amazed by the emu. Governor Lachlan Macquarie was so impressed that, in 1822, he sent two emus as gifts to the Governor-General of India, the Marquis of Hastings. When Macquarie set sail from Australia back to England on the ship Surry, he wrote that voyaging with the passengers were "pets" that included six emus, travelling in roomy well aired pens well-aired pens. The animals were to be given as gifts to friends and patrons of Governor Macquarie back in England. Unfortunately many of the pets, including one of the largest emus died on the trip.
In l791 John Harris, who arrived in the new colony as a surgeon, wrote that emus were swifter than the fleetest of greyhounds. Emu eggs were described as dark Green with little black specks the of pins. It is a little larger than goose eggs. The emu is Australia’s largest bird standing up to 2 metres high. lt has wings but it can°t fly. lt can run really quickly around 50 kilometres per hour. The legs are also yery powerful and used for fighting, especially if males are fighting over females. Emus are common throughout mainland Australia but not in dense rainforest and urbanised areas. They are highly nomadic, which means they must move as they need in search of food, water and shelter.
An emu°s courtship is a boisterous affair. There ISs lots of bobbing up and down, weaying and dipping, throat drumming, grunting and fluffing of feathers. Mating begins late in December: The female flattens a platform of grass into a large nest and lays her clutch of between 7 and 11 dark green eggs lthough it could be as high as 20. lf it is a good season and there is plenty of rain she might lay one or two more clutches with different males.
After laying her eggs she leaves. The male has the sole responsibility for parenting. When the eggs are laid, the male gets broody and begins incubation before the clutch is completed. The female stops mating with the male but might continue to lay eggs in the nest. which are fertilised by other males. It takes 56 days of incubation before the eggs hatch and striped chicks appear, usually in early spring. During this time the male emu sits on the eggs. rarely leaying the nest and only standing to turn the eggs every few hours. He doesn't eat or drink. Drawing on fat reserves, he looses about eight kilograms.

Drink Your Own P.
It says in the Bible that a time will come when Man will eat his own .... and drink his own .... This is not so absurd as it sounds. Already effluent is cleaned and recycled as drinking water in populated cities. Plans are also afoot to use human waste as crop fertilizer.
With reusable energy a high priority for the future, this agenda will probably be followed for high density regions of the world. If clean water is not available everywhere disease will spread across the globe. Production of food will also have to be maximized. Human waste is not the primary fertilizer yet.
Obtaining sufficient amounts of food and water is under threat from global warming. Make no mistake: climate change is a reality. It is not a fear campaign by the political Left. Denial is stupidity. The planet is a degree warmer today that is has been in past centuries. Predictions of a rise of at least two degrees are in the offing.
The Internet has come at the right time for Man. More efficient communication will be needed to create and deliver the staples of human life. Political refugees have been a thorn in Australia's side for a long time now. There is no prospect that this country will be a target for climate refugees. Climate change will have a greater effect here than anywhere else.

Australian Leaders Wear Ear Muffs to Keep Out Global Warming
Prime Minister Tony Abbott and his mate Maurice Newman are both as thick as a post. They are both climate change skeptics. Business advisor Maurice Newman wants a Royal Commission into the Bureau of Meteorology (BoM) claiming that it has doctored temperatures to support global warming.
If anyone is looking for a phantom in the cupboard it is the couple above. After all, Tony Abbott blindly believes that there is a God. How stupid is that in this day and age - religious fanatics not withstanding? In regard to God, you can knock on the door but there is no one home.
So the Australian weather authority is lying. What about weather departments in other countries? The poles are clearly melting. Global warming is a fact. Take note skeptics: scientists are telling the truth.
That is the trouble with "businessmen": they don't want a free market; they want a fixed market. They want to legislate to ban any reports of global warming because it is bad for business.
In the long run Tony Abbott's removal of the carbon tax will make him look ridiculous. Other countries will eventually take action to curb world pollution. More natural disasters due to a hotter planet will prove a cost too hard to bear.

Carbon Sinks in Australia Reduce Carbon
As carbon pollution continues what will happen to the Australian climate? We have just had the warmest May on record and are heading for the mildest winter ever. This will probably mean a stinking hot summer. Heat is rising while places like the United States are getting extremely cold conditions. This is mainly due to a permanent change in the Gulf Stream.
Because Australia is large open savannah, it does store carbon, but storage is only short term. It will be released again further down the track. Ironically, plants are absorbing more anthropogenic CO2 (man-made) than ever before. It seems the higher level of carbon is making flora work harder.
Forget pollution from cars it is maintenance of the Amazon Rain Forest that is important. As more land is cleared to make money residual carbon in the atmosphere will rise.
A change "is" taking place. Arid areas like Australia are getting greener. Warmer conditions seem to increase rain and plant growth. This is mostly in the tropical northern regions - the top half of the country. When El Niño returns this could all change. El Niño = hot and dry.

Climate Change is Inevitable
Australia is one the world's major producers of wheat. If climate change reduces national output there will be widespread consequences. The economy will suffer with the need to import wheat. Internationally, a wheat shortage will put prices up and many poor people will have to go without.
On the positive side some regions of Australia will get more rain. People will still be able to "fatten up" on sugar and rice, despite research showing that sugar contains no nourishment whatsoever for the human body. Two centuries ago a group of British sailors was shipwrecked on the west coast of Africa. The ship was beached. Even though the ship had a full load of West Indian sugar they all died of malnutrition.
Getting back to the main point. There will be competition for arable land pushing land prices up. There is also a link between the land and sea. Climate change will reduce the fish catch. Living in the bush will become impossible with farming failing to prop up local economies.
Potential for farmers to move up into higher areas is limited because Australia is a flat continent. Of course, we could all choose to move south. This would create the need for massive new investment in infrastructure.
These problems will affect the generation of children living today. By 2050, the food bowls in South Australia for sheep and beef will be no more. Man had little impact on the environment in the past, so we do not have the "genes" to change our ways. Pollution will inevitably continue until all the damaging changes above come to fruition. People working today will for the most part be dead. "It isn't our worry is it mate?"

Hot La Niñas Will be Normal
We are getting very hot conditions with flooding. This is seen by many as unusual. Australia has very hot dry weather followed by cooler wet weather in its regular pattern. There is a 100 year cycle in El Niño and La Niña events. In other words severity peaks every century.
Australia is currently in a transition period. The La Niña could continue or it could change to El Niño. There is presently a lot of rain. Oddly there is also a drought inland. If it were an El Niño cycle things would be a lot worse. It seems global warming is making La Niña years very hot.
Australia is now getting hot La Niñas along with very hot El Niños. This is bad for the whole world because all continents are affected by weather in the Pacific Ocean.
Some El Niños reach a critical temperature with dry periods being severe. Global warming means that more of them will go over this critical point. The average of extreme El Niños has been one in twenty years.
Australians fear hot dry periods. This was the reason for Queensland's over-investment in bringing water to Brisbane. Now many say it was money wasted, but in the future this capital outlay could pay for itself. The hot dry weather will return and 40 degree days could go on for weeks.

Summer Snow Falls in Australia
The weather is changing everywhere. It is not only getting hotter and more humid, i.e., rain; it is also getting colder in some places. The climate is erratic. It is all over the place. Peak summer in Australia is December and January. There is snow in the Australian Alps. This is unheard of. A cycling event on the weekend could be postponed.
Once every summer there is a very small snow "shower", but that is usually it. This year is different. The snow is getting heavier and it is in the low areas where they never get snow in summer. It is 20 cm deep in some areas.
Weather forecasting is improving, however. Snow was predicted a week ago. Summer tourists are arriving and they are not bringing winter clothing. Hopefully, the weather will improve and local income will not be affected as tourism is the regions major industry.
