Threats: Climate change

Publication | April 1, 2008 at 16:54

Global warming occurs when the heat from the sun hits the surface of the Earth and begins to radiate back towards outer space, but is trapped by too many greenhouse gases in the atmosphere.

There is no silver bullet technology that will provide for the world’s needs – likely a mix of several different renewable sources will be needed – what is clear however is that it’s not the technology that’s lacking but the political will to...

Nuclear waste is produced at every stage of the nuclear fuel cycle, from uranium mining and enrichment, to the operation of the reactor and the reprocessing of spent nuclear fuel. Much of this nuclear waste will remain hazardous for hundreds of...

Tritium Q&A

Publication | April 1, 2008 at 14:19

Tritium is radioactive water or water vapour. It’s not something in the water, but the water molecules themselves that are radioactive. Tritium is the radioactive isotope of hydrogen. That means tritium is unstable and gives off radiation when it...

“Nuclear terrorism is still often treated as science fiction — I wish it were. But unfortunately we live in a world of excess hazardous materials and abundant technological know-how, in which some terrorists clearly state their intention to...

Safe reactors are a myth. An accident can occur in any nuclear reactor, causing the release of large quantities of deadly radiation into the environment. Even during normal operation, radioactive materials are regularly discharged into the air...

Proliferation of nuclear weapons

Publication | April 1, 2008 at 13:09

The UN International Atomic Energy Agency (IAEA) is dedicated to the worldwide expansion of nuclear power, but it is also meant to be the watchdog for illegal nuclear weapons development. That contradiction is the key reason why the proliferation...

Nuclear power Q&A

Publication | April 1, 2008 at 12:50

Nuclear power is dirty, dangerous and expensive. With cancer-causing emissions and radioactive waste, nuclear power is not a clean alternative to fossil fuels. Greenpeace supports a phase-out of nuclear power in Canada.

Extreme weather

Publication | April 1, 2008 at 9:39

There is strong evidence that extreme weather events – such as hurricanes, floods, droughts and heat waves – are increasing because of climate change.

Habitat loss

Publication | April 1, 2008 at 9:24

The climate is changing faster than at almost any time in our planet's history. Without a dramatic cut in greenhouse gas emissions, the die out in species could be astonishingly severe.
