Craig Kelly, a prominent Liberal Party backbencher, has told party members in Sydney they should not worry about climate change and that fossil fuels were among the reasons "we are so safe".

Addressing a gathering of members last week at the Middle Harbour Yacht Club, Mr Kelly said "we've always had dangerous weather" and that "even the climate has changed in space".

"The reality is today, we live in a time where our generation has never ever been as safe from the climate at any time in human history," Mr Kelly told the group on Wednesday, according to a recording of his speech.

"The climate was always dangerous. We didn't make it dangerous, [and] it's fossil fuels that protect us from that climate."
