Claim: The worsening of tidal flooding in American coastal communities is largely a consequence of greenhouse gases from human activity, and the problem will grow far worse in coming decades, scientists reported Monday.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The effects of global warming or climate damage include far-reaching and long-lasting changes to the natural environment, to ecosystems and human societies caused directly or indirectly by human emissions of greenhouse gases.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Among other findings, the report concluded that sea level rises could be up to two feet higher by the year 2100, even if efforts to reduce greenhouse gas emissions and to limit global warming are successful; coastal cities across the world could see so-called "storm[s] of the century" at least once a year.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The introduction includes this statement: There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: US National Academy of Sciences: "In the judgment of most climate scientists, Earth's warming in recent decades has been caused primarily by human activities that have increased the amount of greenhouse gases in the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The main idea in the report according to one of his authors Michael Oppenheimer is that if humanity will drastically reduce Greenhouse gas emission in the next decades the problem will be tough but manageable.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Human activities (primarily greenhouse gas emissions) are the primary cause.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Increasingly, climate change is threatening human communities around the world in a variety of ways such as rising sea levels, increasingly frequent large storms, tidal surges and flooding damage.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Human activities, primarily the burning of fossil fuels (coal, oil, and natural gas), and secondarily the clearing of land, have increased the concentration of carbon dioxide, methane, and other heat-trapping ("greenhouse") gases in the atmosphere...There is international scientific consensus that most of the warming observed over the last 50 years is attributable to human activities.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate change caused by human activities that emit greenhouse gases into the air is expected to affect the frequency of extreme weather events such as drought, extreme temperatures, flooding, high winds, and severe storms.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Atmospheric concentrations of anthropogenic (i.e., human-emitted) greenhouse gases have increased substantially.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Further, methane is a potent greenhouse gas as it is released into the atmosphere, so it causes warming, and as the ocean transports this warmth to the bottom sediments, it destabilizes more clathrates.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Human activities are now causing atmospheric concentrations of greenhouse gases—including carbon dioxide, methane, tropospheric ozone, and nitrous oxide—to rise well above pre-industrial levels ... Increases in greenhouse gases are causing temperatures to rise ...

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The biggest wellspring of greenhouse gas emissions are from human activities.
