Climate and climate change

Wayne Swan warns climate change will reshape politics as much as 9/11

An independent organization of leading scientists and journalists researching and reporting the facts about our changing climate and its impact on the public. Climate Central surveys and conducts scientific research on climate change and informs the public of key findings. Our scientists publish and our journalists report on climate science, energy, sea level rise. Read More. Members of the Climate Central staff and board are among the most respected leaders in climate science. Staff members are authorities in communicating climate and weather links, sea level rise, climate. A new Climate Central report finds an increase in extreme heat index days, which greatly impacts outdoor sports and the risk of heat illnesses.

Anthony Albanese has signalled all the policies Labor took to the election are up for review. While the electoral backlash against Labor in coal seats in Queensland and New South Wales has prompted more effusive expressions of public support for the mining sector , senior opposition figures are insisting there will not be a major retreat from climate action in this term of parliament.

Swan said that transformation reflected long-term investment decisions and a significant shift in the economics of energy, rather than the specifics of climate regulation.

Evidence that CO2 emissions are the cause of global warming is very robust. Scientists have known since the early s that greenhouse gases in the atmosphere trap heat. As a result, the concentration of CO2 in the air has reached more than parts per million by volume ppm , compared to about ppm in around the start of the Industrial Revolution. We can link the rises in temperature over the last years to rises in atmospheric CO2 levels. Greenhouse gas levels are now well above the natural cycle of the last , years. However, instead of cooling, the Earth has warmed over this period.

Climate change and global warming are often used interchangeably but have distinct meanings. Similarly, the terms "weather" and "climate" are sometimes confused, though they refer to events with broadly different spatial- and timescales. Climate change refers to a broad range.

Some of the incoming sunlight is reflected directly back into space, especially by bright surfaces such as ice and clouds, and the rest is absorbed by the surface and the atmosphere. Much of this absorbed solar energy is re-emitted as heat longwave or infrared radiation. The atmosphere in turn absorbs and re-radiates heat, some of which escapes to space. Any disturbance to this balance of incoming and outgoing energy will affect the climate.

Protecting nature today means a better planet for future generations. Seventeen of the 18 warmest years have occurred since Eleven percent of all global greenhouse gas emissions caused by humans are caused by deforestation comparable to the emissions from all of the cars and trucks on the planet. The Amazon is a carbon-storing powerhouse. Just 0. Nearly 1 million hectares lost.

Millions of people are already suffering from the catastrophic effects of extreme disasters exacerbated by climate change from prolonged drought in sub-Saharan Africa to devastating tropical storms sweeping across Southeast Asia, the Caribbean and the Pacific. During the summer months for the northern hemisphere in , communities from the Arctic Circle to Greece, Japan, Pakistan and the USA experienced devastating heatwaves and wildfires that resulted in the deaths of hundreds of people. While we largely understand climate change through the impacts it will have on our natural world, it is the devastation that it is causing and will continue to cause for humanity that makes it an urgent human rights issue. It will compound and magnify existing inequalities. And its effects will continue to grow and worsen over time, creating ruin for current and future generations. This is why the failure of governments to act on climate change in the face of overwhelming scientific evidence may well be the biggest inter-generational human rights violation in history. The planet's climate has constantly been changing over geological time, with significant fluctuations of global average temperatures.

Earth's climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. Global climate change has.

Many people do not know what it really amounts to, either due to unreliable sources or deliberate misinformation, which has led to a series of myths about climate change. In these pages, we tackle the subject from an objective, scientific viewpoint , discussing the causes and consequences of climate change and how it should be tackled. First, we need to clarify two concepts often mistaken for synonyms: climate change and global warming. There is an important difference between them, however, given that it is global warming that causes climate change. Without the greenhouse effect, the average temperature of the planet would be 0 C.

Understanding and predicting what the coming winter might bring, or predicting how climate will change over the next century is of vital importance - both for our economy and for society. Climate can be thought of as the average or typical weather conditions we experience. Scientists know that climate varies naturally on many timescales and they know that people are affecting climate - particularly through emissions of greenhouse gases. At the National Centre for Atmospheric Science, scientists are investigating how natural and human factors are affecting climate and what this means for the future. Our climate is powered by the Sun and modified by our atmosphere, which is made up of various gases. Some of the gases in the atmosphere allow sunlight to pass through, and prevent the heat from escaping back out into space, similar to glass in a greenhouse. This is called the natural greenhouse effect Figure 1.
