Climate Change - Buildings Down and the Surf

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. Coastal buildings will be inundated and lost forever. Oddly, this is bad news for surfers. As the sea rises the surface becomes smoother. This means smaller waves on the beaches. The era of Australia being a surfing nation could come to an end. Storms along the coast will decrease further exacerbating the problem. With more water volume, temperature differences in the ocean even out leading to calmer weather. The few storms that will occur will be very large indeed. High-rise buildings on the Gold Coast in Queensland will fall into the sea. We will lose our tourist mecca.

Climate Model Scientists Are in Decline

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 teaching all these. Consequently, such gifted individuals must be sought rather than taught. The number of climate experts is declining.

Storms Are Getting Stronger and More Frequent

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 presume it is an aspect of global warming. Rising seas with stronger storms will cause more erosion in coastal regions.
