Claim: As the temperature has increased, so has the ability of scientists to determine whether specific events are linked to climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Attribution of recent climate change is the effort to scientifically ascertain mechanisms responsible for recent global warming and related climate changes on Earth.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: For example, scientists have established causal links between human activities and the changes in snowpack, maximum and minimum (diurnal) temperature, and the seasonal timing of runoff over mountainous regions of the western United States.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: This has led to increases in mean global temperature, or global warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Although proving that particular weather events are due specifically to global warming may never be possible, methodologies have been developed to show the increased risk of such events caused by global warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Increases in ambient temperatures and changes in related processes are directly linked to rising anthropogenic greenhouse gas (GHG) concentrations in the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate change refers to a broad range of global phenomena ...[which] include the increased temperature trends described by global warming."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Within scientific journals, global warming refers to surface temperature increases while climate change includes global warming and everything else that increasing greenhouse gas levels affect.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Scientist seek periods that are in some sense analogous or informative to current climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Scientists rely on such studies to attribute observed changes in climate to a particular cause or set of causes.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: While ‘climate change’ can be due to natural forces or human activity, there is now substantial evidence to indicate that human activity – and specifically increased greenhouse gas (GHGs) emissions – is a key factor in the pace and extent of global temperature increases.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Scientists have identified many episodes of climate change during Earth's geological history; more recently since the industrial revolution the climate has increasingly been affected by human activities driving global warming, and the terms are commonly used interchangeably in that context.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate change means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Attribution of the temperature change to natural or anthropogenic (i.e., human-induced) factors is an important question: see global warming and attribution of recent climate change.
