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:
“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (1889–1974)
“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)
“Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
—Anton Pavlovich Chekhov (1860–1904)
