Thousands of photos have been sent to National Geographic as part of its 'Climate Change: In Focus' assignment.

The pictures depict scenes of crisis around the world, animals and people reacting to landscapes affected by climate change.

"I took this photo from my neighbour's deck overlooking the lights of Orinda. The extreme multi-year drought in California has been the enabler of hundreds of devastating wildfires," photographer Eric Smith said.

Photographer Patty Waymire says locals she spoke to in Kaktovic, Alaska told her about the unseasonably warm winter which means there is no snow when there should be.

"This will have an impact on the local polar bear population, when it comes time to hunt seals for their food in the winter months," she said.

Photographer Ghaneshwaran Balachandran said he decided to treat his body as a canvas to raise awareness that only people can change the way we treat our one and only planet.

"The first subject that came across my mind about climate change was the massive scale of fossil-fuel demand.

"Our greed and dependency for oil has lead to many consequences such as the release of greenhouse gasses. These gasses are responsible for global weather and temperature change, causing everything else listed on my skin."

The pictures were exhibited at COP 22 Climate Summit in Morocco this month, and seen by many of the world's top leaders and policy-makers.

It is hoped the photos will inspire people to care about the planet.
