Warming Oceans

Pete has spent years inquiring into, raising awareness of and campaigning against the catastrophic impacts of global warming on marine ecosystems around Australia, indeed the globe.

Pete recently delivered an impassioned speech in the Senate regarding the death of our oceans. The speech went viral and was reported on by a number of international news agencies.

Pete has been outspoken in demanding that UNESCO must consider climate change impacts when assessing the status of the world’s coral reefs, including the Great Barrier Reef.
