Greenpeace Energy [R]evolution shows direction at climate crossroads

Coal is the worst climate offender Enlarge Image

Stop climate change

The world's leaders meet at the end of 2009 in Copenhagen to determine the fate of the climate. They could set us on the path to a deep emissions cuts or they could lock the planet into catastrophic, irreversible climate change.

Take action

With the world on the brink of runaway climate change, millions are anxious about the effects that a warmer globe will have on our everyday lives. Wanting to learn, act and agitate is a perfectly valid response.

Science

Climate change is a reality. Today, our world is hotter than it has been in two thousand years. By the end of the century, if current trends continue, the global temperature will likely climb higher than at any time in the past two million years. While the end of the 20th century may not necessarily be the warmest time in Earth's history, what is unique is that the warmth is global and cannot be explained by the natural mechanisms that explain previous warm periods. There is a broad scientific consensus that humanity is in large part responsible for this change, and that choices we make today will decide the climate of the future.

Scientific consensus

There is, in fact, a broad and overwhelming scientific consensus that climate change is occurring, is caused in large part by human activities (such as burning fossil fuels), and if left un-checked will likely have disastrous consequences.

Climate research

It was realised by the mid-18th century that some gases in the Earth's atmosphere, such as carbon dioxide, trap heat and keep the Earth warm. At the start of the 20th century, a Swedish scientist named Svante Arrhenius put forward the idea that human emissions of carbon dioxide would eventually raise temperatures. He didn't see this as a particularly bad thing, and most scientists at the time were sceptical that humans could burn fossil fuels fast enough to have a noticeable impact at all.

CO2 emissions

The primary human source of carbon dioxide (CO2) in the atmosphere is from the burning of fossil fuels for energy production and transport. Changes in land use and deforestation also contribute significantly. Trees, for example, are natural 'carbon sinks' - they absorb carbon dioxide while alive and when they are destroyed, carbon dioxide is released into the atmosphere. Once in the atmosphere, most of the carbon dioxide stays there for 50 to 200 years, and some of it stays there indefinitely.

Governments

There is a fundamental irony and injustice at the heart of the climate change problem. Today’s growing body of evidence indicates very clearly that the first and worst impacts of climate change are felt by the poor in the developing world. The responsibility for the problem, however, lies primarily with the rich industrialised nations, and increasingly the rapidly industrialising nations.

United Nations

The United Nations plays a key role in coordinating the international response to climate change. But it is no simple job getting cooperation and agreement from the 191 member states of the UN - all intent on pursuing their own self interests and policies - even when the evidence is clearly shows that failing to act would be disastrous for all.

Project work

Climate change is a priority issue for us here at Greenpeace. We realised years ago that it has the potential to wipe out most of the gains the environmental movement has made in other areas. Disruptions to ecosystems will likely harm everything from minke whales to coral reefs to polar bears. Whole forests will be lost, and hundreds of thousands of species will become extinct. Climate change will also bring devastation to people and communities, especially some of the world's poorest.

International negotiations

This page is intended primarily for policy makers, journalists and others who attend or report on international meetings about climate change. Hopefully though, it is also useful to anyone who wants better understanding of what goes on at these meetings, and what is at stake from their results.

Solutions

Greenpeace is pushing for some big, visionary measures to turn around the global trend towards runaway climate change. The plan needs political will to make it happen and the opportunity is at the Copenhagen summit in December. You can get behind our plan in a whole lot of different ways. Here's how.

Building a toxic free, sustainable home for low-income families. The house is free of toxic materials like PVC, the wood is from sustainable forests and the construction is solar powered. Enlarge Image

Energy efficiency

Energy efficiency is a very broad term referring to the many different ways we can get the same amount of work (light, heat, motion, etc.) done with less energy. It covers efficient cars, energy saving lights, improved industrial practices, better building insulation and a host of other technologies. Since saving energy and saving money often amount to the same thing, energy efficiency is highly profitable.

Wind

Wind power, the world's fastest growing energy source, is a deceptively simple technology. Behind the tall, slender towers and steadily turning blades lies a complex interplay of lightweight materials, aerodynamic design and computer controlled electronics. Power is transferred from the rotor through a gearbox, sometimes operating at variable speed, and then to a generator (although some turbines avoid a gearbox by use of direct drive).

Solar - Sunlight to Energy

Solar Energy is already being harnessed in many part of the world and it has the potential to provide several times the current world energy consumption if properly exploited. Solar can be used to directly produce electricity or for heating and even for cooling. Future potential of solar is only limited by our willingness to seize the opportunity.

Geothermal

Geo (Earth) thermal (heat) energy means harnessing heat from inside the Earth. Our planet's core is incredibly hot – 5,500° Celsius (9,932° F) by recent estimates – so it's no surprise that even the top three metres of Earth's surface stay a nearly constant 10-16° Celsius (50-60° F) year round. Plus, thanks to various geological processes, at some places much higher temperatures can be found in some places.

Bioenergy

Bioenergy (aka biomass energy) is using organic matter (plants, etc.) as fuel via technologies such as gas collection, gasification (converting solid material to gas), combustion and digestion (for wet wastes).

Hydroelectric

Hydroelectric energy is water energy. Moving water contains an enormous store of natural energy, whether the water is part of a running river or waves in the ocean. Think of the destructive force of a river breaking its banks and causing floods or of tall waves breaking on a shallow coastlines, and you can visualize the amount of power involved.

Greenfreeze and solar chill

Sometimes you just have to show the world how it's done. Greenfreeze is Greenpeace's market proven, environmentally friendly, refrigeration technology. The SolarChill project aims to create a stand-alone solar powered refrigerator that not only preserves food, but also meets the World Health Organization's standards for vaccine storage.

Questions about solutions answered, and some myths debunked.

End the nuclear age

Greenpeace has always fought - and will continue to fight - vigorously against nuclear power because it is an unacceptable risk to the environment and to humanity. The only solution is to halt the expansion of all nuclear power, and for the shutdown of existing plants.

Abolish nuclear weapons

The Cold War may be over, but this does not mean nuclear weapons have disappeared. Far from it: There are over 30,000 nuclear weapons in the world, with more than a thousand of them ready to launch at a moment's notice, 24 hours a day, seven days a week.
