If the CO2 dumped into the atmosphere was over 450ppm Australia and Asia and the Pacfiic can expect more wars, and more forced migrations, and more invasions in a direct relationship to the proportion of CO2 dumped in the atmosphere said the Garnaut Climate Change Review Draft Report.
(Full Article)The forecast temperature changes had created the need for two new categories of fire weather: very extreme and catastrophic.
(Full Article)Since early industrial times (1850-1899) the total global surface temperature increase has been estimated at 0.76C 0.19C. The data shows temperature difference from the 1961-1990 mean. The black line shows the annual values after smoothing with a 21-point binomial filter. Since 1979, the rate of warming has been about twice as fast over the land as over the ocean. During the last century, the Arctic has warmed at almost twice the global average rate.
(Full Article)Governments’ acceptancce of lobby group cases for short term profits had allowed growth in fossil fuel CO2 pollution. This had created a future with catastrophe as a way of life. Species faced extinction, was ahead, due to shifts in habitat caused by temperature and climate changes, It was also very possible the Greenland ice sheet would melt, and sea levels would show marked rise.
(Full Article)Maximum temperatures are increasing at a greater rate than mean temperature. The attribution of changes in rainfall patterns in Australia to climate change is difficult due to naturally high interannual variability. Attribution has been possible in the south-west of Western Australia, where up to 50 per cent of the rainfall decline has been attributed to human-induced climate change
(Full Article)As oceans heat up, they expand, causing the volume of the ocean to increase and global mean sea level to rise. Sea level also rises when mass is added through the melting of grounded ice sheets and glaciers. The total sea-level rise for the 20th century, including contributions from thermal expansion and land ice-melt, was 170 mm. Measurements show that the average rate of sea-level rise in the period 1961-2003 was almost 1.8 0.5 mm per year.
