The atmosphere is a cloud of gas and suspended solids extending from the Earth's surface out many thousands of miles, becoming increasingly thinner with distance but always held by the Earth's gravitational pull.
The atmosphere is made up of layers. it surrounds the Earth and holds the air we breathe; it protects us from outer space; and holds moisture (clouds), gases, and tiny particles. In short, the atmosphere is the protective bubble we live in. This protective bubble consists of several gases (listed in the table to the right) with the top four making up 99.998% of all gases. Of the dry composition of the atmosphere nitrogen, by far, is the most common. Nitrogen dilutes oxygen and prevents rapid burning at the Earth's surface.
It is also necessary for combustion or burning. Argon is used in light bulbs, in double-pane windows, and to preserve the original Declaration of Independence and the Constitution. These percentages of atmospheric gases are for a completely dry atmosphere. Your Guide To Understanding Energy. Energy Resources. CSIRO - Climate Change. Glen Paul: G’day, and welcome to CSIROvod, I’m Glen Paul.
Climate change is a serious threat to the planet, and greenhouse gas concentrations are believed to be a major contributor. In this vodcast, we're going to meet scientists working at measuring green house gas concentrations over time, and the finding that they've been rising rapidly over the past two centuries, in other words since the time of the industrial revolution. It was at that time we began to burn large amounts of coal to power our steam engines for industry, and to generate electricity, and while the technology has greatly improved we’re still using fossil fuel in quantities thousands of times more than we did in the 1800s. Sea-level Rise - CSIRO. We love the coast.
Coastal regions, particularly some low-lying river deltas, have very high population densities. In excess of 150 million people live within 1 metre of high tide level, and 250 million within 5 metres of high tide. There are billions of dollars invested in coastal infrastructure immediately adjacent to the coast. Many of the world's mega cities (populations of many millions) are on the coast.
The Oceans are changing. A recent issue of the journal Science has focused on a number of aspects of ocean change, including sea-level rise. A (pdf) reprint of this editorial can be obtained from here. This sea-level rise is a response to increasing concentrations of greenhouse gases in the atmosphere and the consequent changes in the global climate. On this web site, we attempt to bring together information on sea level rise and its causes.

The science of climate change: questions and answers An updated edition of The science of climate change: questions and answers will be released in mid-2014.
This publication aims to address confusion created by contradictory information in the public domain. AAS- The Greenhouse Effect. Without the greenhouse effect we would be living in a very chilly place – the world's average temperature would be minus 18°C, instead of the 15°C we are used to.
So what is the greenhouse effect and how does it make Earth around 33°C warmer? The natural greenhouse effect The natural greenhouse effect is a phenomenon created by gases naturally present in the atmosphere that affect the behaviour of the heat energy radiated by the sun. In simple terms, sunlight (shortwave radiation) passes through the atmosphere, and is absorbed by the Earth's surface. National Center for Science Education. The National Center for Science Education is the only national organization devoted to defending the teaching of climate change in public schools.
Human-caused climate change is not scientifically controversial. Although most U.S. adults believe that the climate is changing, only about half know that human activities are substantially responsible. UK Met Office - Climate guide. Find out about climate, climate change and climate science in our climate guide The following pages include information around what climate is and what influences it, how and why our climate is changing and the work we undertake to help the UK prepare for future changes.

Climate change Promoting sustainable development and combating climate change have become integral aspects of energy planning, analysis and policy making.
Because energy accounts for two-thirds of total greenhouse gas emissions and 80% of CO2, any effort to reduce emissions and mitigate climate change must include the energy sector. Global energy-related CO2 emissions grew by 1.4% in 2017, reaching a historic high of 32.5 gigatonnes (Gt), a resumption of growth after three years of global emissions remaining flat.
The increase in CO2 emissions, however, was not universal. While most major economies saw a rise, some others experienced declines, including the United States, United Kingdom, Mexico and Japan.
