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.

Global Warming Threatens Native Marine Species

As meteorologists tell us that natural disasters are becoming regular occurrences due to climate change, so the threat to certain animals species increases. Marine animals are in serious danger. The sea is warming up.

It is accepted that whales beaching themselves is "normal". However, dugong doing the same thing is not. CSIRO which is always at the forefront of Australian research says that south-eastern and north-western sea regions around Australia have become significantly warmer.

As some species move or even die out and new species arrive the ecological dynamic is disrupted. Death from new diseases becomes the norm. New species eat the food that native creatures eat, so marine animals that have been in the same place for thousands of years are doubly threatened.

The future looks bleak. The climate could level off and remain changed but stabilize. On the other hand, change could be ongoing and the variation in marine species could decline. This could affect food supplies for people.

Climate Change Could Make Timid Animals More Aggressive

Climate change can cause changes in behavior. As water becomes warmer so some species of fish become aggressive. Some fish are inherently timid while others are bold. In experiments on fish from the Australian Barrier reef, when water was slowly warmed normally timid fish became aggressive. Their rate of activity increased as well. Evolution has created fish that fit into a niche where survival depends on a fish being very careful about its surroundings. If they openly attack larger fish it could mean the smaller ones will be eaten.

It is possible that similar changes will occur with reptiles, amphibians, ectotherms and even mammals. If timid animals become bold then they could be killed off by predators or by humans using harvesting equipment trying to catch other animals for food. Only a very small increase in temperature led to the change.

In the tests, fish were bred in captivity then released into holding tanks where the water was slowly warmed. They had no chance to socialize with wild fish. When the water was cool the fish hid in plastic pipe. As the water heated up the fish ventured further from the protective pipe.

Certain assumptions can be made from this research. As the Arctic ice disappears, Polar bears wandering near small towns in Alaska, Canada and Northern Europe could become more brazen in their search for food from garbage cans and dump sites. They could kill humans more frequently in their anger. Similarly, rats living in these cold climes may not just die of shock when hit. They could turn on people and fight back.
