While a new very strong El Niño is on the way, fears of continuing La Niña are real as well. Although Australia is known as a drought country, severe floods are damaging. This is because the continent is flat with a few mountains in the east of the country. If the El Niño does not arrive flooding will continue. Furthermore, the drought in the US will cause further damage to their economy. The odd thing at the moment is that Australia has drought inland with flooding along the coast. This isn't s normal state of affairs. It could be due to global warning. We have had a very long intermediate period where La Niña persists and El Niño threatens. Research shows that La Niña will return every 13 years instead of 23 years. It seems to Australians that La Niña has been here for ever with the long intermediate period persisting. There are extreme El Niño and La Niña though. And it is these that do the most damage economically and socially. ✴ Science by Ty Buchanan ✴ ...

The future does not look good for Australia. People fail to grasp the fact that as climate change "bites" the economy will suffer. Erratic weather patterns will affect food production. There will be shortages and prices will rise. Insurance will become unaffordable as claims get bigger and disasters happen more often. Just one incident on November 27 caused a half a billion dollars of damage in Brisbane. At present, crises seem to be occurring more often. We are told this isn't yet the case, but they are getting stronger. Hotter more humid conditions are causing this. Water will surely lead to some damage. Strong winds will be the greatest danger. Only strong storms hitting populated areas are reported, yet they happen all over the country. There is a concentration on the Eastern Seaboard, however. Another increasing problem is hail. More of it means a higher number cars will be written off. Storms are predicted to double by the end of the cen...

Australia has always been a harsh place to live. Despite the luxury living on the coast with all the latest modern services, inland there is a desert. Many people who are born in the harsh center remain there all their lives. A fewer number choose to live there moving from coastal cities. Let's face it many prefer the heat over the cold and they have personal reasons for choosing to do this. We do yet know what lies ahead for us in this vast continent. Climate change is happening at this very moment most definitely. El Niño and La Niña are the major factors influencing the weather on the east coast. Scientists forecast more extremes from these usually opposite climate impacting factors. The intermediate stage between these cycles has lasted for several years now. Weather is very unpredictable ranging from drought inland to too much rain on the coast. It seems we experience one or the other extreme with changeable in between. The level of the ocean is rising. Co...

Climate models are presumed to be far too complicated for the layman to understand so they are left to the experts. However, the models save lives and valuable infrastructure. The complicated lines of code make predictions about future weather patterns. Just a few decades ago weather could not be forecast for two days ahead. Currently, five day forecasts are common and they are reliable. Even seasonal outlooks are treated as valid. For examples, we have been told in Queensland that there will be a wet summer. The all-seeing weather bureau is counted on to provide information about strong winds, hailstorms, cyclones and even the direction of forest fires. To get an accurate prediction, up to date and correct data must be fed into the models. Computers are getting larger all the time and more complex models are being formulated. This is a complex job. Scientists need to draw on many specialized fields in physics, mathematics and computer science. No university offers a course te...

It is accepted that we are getting more rain though it evaporates very quickly and leads to drought. The cycle of evaporation and rain is speeding up. The planet it heating up as the poles are melting. Glaciers are reducing in size with the water flowing into the oceans thus increasing the height of the sea. There is one thing that has not been studied in depth - wind. Tornadoes are getting stronger. Furthermore, storms with high winds are becoming more frequent and stronger. Over the last decade storm winds have become five per cent faster. The highest strength winds have increased by ten per cent. Analysis of wind change is not that easy. Wind does not show up in satellite pictures. Special equipment such as radar altimeters are put onto satellites. They get data by scanning for echoes. The frequency and strength of storms is definitely increasing. It is not yet proven to be due to global warming. This could be a cyclical phenomenon. Nonetheless, it is drawing a long bow not to presu...

Something is happening - out there! Yes, something mysterious has occurred in space. Astronomers are aghast at the total disappearance of a broad ring around Jupiter. This is a shock and totally unexpected. Things in space are supposed to be quite stable. The ring was not on a picture taken on May 8. The band was very large, twice as broad as the diameter of Earth. A view with binoculars clearly shows that the "bottom" half of the planet is now all white. The twin banded planet is now "held together" by a single band - quite disconcerting. Have no fear. The disappearance could be only temporary. Jupiter's second belt could be covered by cloud higher in the planet's atmosphere. Ammonia can cause ice crystals to form which develops into cirrus clouds. Wind patterns have probably changed on the planet. This has led to a climate change. Just why the bands are brown is a mystery anyway. Only a few probes have been sent to Jupiter so knowledge about it is limited....
