Climate
Analysis of future emissions trajectories indicates that, left unchecked, human emissions of greenhouse gases (GHG) will increase several fold during the 21st century. Consequently, Australia’s annual average temperatures are projected to increase 0.4–2.0°C above 1990 levels by the year 2030, and 1–6°C by 2070. Average precipitation in southwest and southeast Australia is projected to decline during this time period, while regions such as the northwest may experience increases in rainfall. Meanwhile, Australia’s coastlines will experience erosion and inundation from an estimated 8–88 cm increase in global sea level. Such changes in climate will have diverse implications for Australia’s environment, economy, and public health.
A 2007 technical report on climate change in Australia jointly published by Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Bureau of Meteorology provides climate change projections accounting for a number of variables, including temperature, rainfall, and others. The report provides assessment of observed Australian climate changes and causes, and projections for 2030 and 2070, under a range of emissions scenarios.
The Government of Australia acknowledges the impacts of changing climatic conditions, and its Department of Climate Change and Energy Efficiency has established the Australian Climate Change Science Program (ACCSP), which aims to understand the causes, nature, timing, and consequences of climate change so as to inform the Australian response. The ACCSP will dedicate $14.4 million per year towards climate change research and has already made substantial progress with a recent publication, Australian Climate Change Research: Perspectives on Successes, Challenges, and Future Directions.

Famous quotes containing the word climate:
“Certainly parents play a crucial role in the lives of individuals who are intellectually gifted or creatively talented. But this role is not one of active instruction, of teaching children skills,... rather, it is support and encouragement parents give children and the intellectual climate that they create in the home which seem to be the critical factors.”
—David Elkind (20th century)
“There is much to be said against the climate on the coast of British Columbia and Alaska; yet, I believe that the scenery of one good day will compensate the tourists who will go there in increasing numbers.”
—Franklin D. Roosevelt (1882–1945)
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
