Queensland’s Flood Made Worse by Climate Change

The Queensland floods would have occurred without human intervention in the world's climate, but the damaging effects would have been much less.  This has been the conclusion reached by scientists.  At no time can it be said for certain that a particular calamity was caused by climate change.

Climate has clearly been affected by the way we live, the way our lives have changed since the industrial revolution.  Coal was the first blow struck.  This was followed by development of the oil gusling motor vehicle.

Water temperature off the coast of Queensland has never been higher.  This creates rain clouds that drift over the land.  The northern monsoon seems to be moving down the coast.  With this heat has gone cooling temperatures in the east/central Pacific - the dreaded La Nina effect.  The El Nino cycle appears to have slowed down.  Australia was known as a dry country.  Now it is more humid.  The temperature increase of over 1 degree Centigrade on average is a record.  With this permanent rise it means more rain more often

Caterpillars Are Changing into Butterflies Earler

Climate change is making butterflies more violent. They are coming out 10 days earlier than they used to in spring. The change has been caused by a 0.91ÂșC increase in temperature in Melbourne. All species that interrelate with the Common Brown butterfly (Heteronymph Merope) breed earlier as well.

A group of academics funded by the Australian Research Council has researched this issue. Members of the group studied caterpillars bred at the old and new temperature in the laboratory and noted the changed. Observation of the butterfly in the wild has confirmed that caterpillars are changing into butterflies earlier.

If butterflies are coming out sooner then other insects must doing this as well. This means that crops will have to be planted earlier in to be fertilized by insects. People in cities do not understand the importance of pollination on food crops.
