Claim: The bushfires in Australia were caused by arsonists and a series of lightning strikes, not 'climate change'.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The 2007 Kangaroo Island bushfires were a series of bushfires caused by lightning strikes on 6 December 2007 on Kangaroo Island, South Australia, resulting in the destruction of 95,000 hectares (230,000 acres) of national park and wilderness protection area.

Passage: "Climate change is one factor affecting how fires in Australia burn, regardless of whether arsonists or lightning started them".

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Man-made events include arcing from overhead power lines, arson, accidental ignition in the course of agricultural clearing, grinding and welding activities, campfires, cigarettes and dropped matches, sparks from machinery, and controlled burn escapes.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate and fire experts agree that climate change is a factor known to result in increased fire frequency and intensity in south east Australia, and although it should not be considered as the sole cause of the 2019-20 Australian fires, climate change is considered very likely to have contributed to the unprecedented extent and severity of the fires.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In 2014, the Bureau of Meteorology released a report on the state of Australia's climate that highlighted several key points, including the significant increase in Australia's temperatures (particularly night-time temperatures) and the increasing frequency of bush fires, droughts and floods, which have all been linked to climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In 2013, the CSIRO released a report stating that Australia is becoming hotter, and that it will experience more extreme heat and longer fire seasons because of climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Scientific experts and land management agencies agree that severely below average fuel moisture attributed to record-breaking temperatures and drought, accompanied by severe fire weather, are the primary causes of the 2019-20 Australian bushfire season, and that these are likely to have been exacerbated by long-term trends of warmer and dryer weather observed over the Australian land mass.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Due to climate change, Australia is expected to experience harsher extreme weather events, mainly bush-fires and floods during summer.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Some large wildfires in the United States have been blamed on years of fire suppression and the continuing expansion of people into fire-adapted ecosystems, but climate change is more likely responsible.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The new forest and the resulting forest fires may have induced climate change.
