Claim: Goklany has argued that the rising level of carbon dioxide in the earth’s atmosphere ‘is currently net beneficial for both humanity and the biosphere generally.”

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Since global warming is attributed to increasing atmospheric concentrations of greenhouse gases such as CO 2 and methane, scientists closely monitor atmospheric CO 2 concentrations and their impact on the present-day biosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Both have the same net effect, but for achieving carbon dioxide concentration levels below present levels, carbon dioxide removal is critical.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Increases in atmospheric concentrations of CO 2 and other long-lived greenhouse gases such as methane, nitrous oxide and ozone have correspondingly strengthened their absorption and emission of infrared radiation, causing the rise in average global temperature since the mid-20th century.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: As stated in the Convention, this requires that greenhouse gas concentrations are stabilized in the atmosphere at a level where ecosystems can adapt naturally to climate change, food production is not threatened, and economic development can be sustained.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: "High levels of atmospheric carbon dioxide necessary for the termination of global glaciation".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide in the Earth's atmosphere is essential to life and to most of the planetary biosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Earth's natural greenhouse effect makes life as we know it possible and carbon dioxide plays a significant role in providing for the relatively warm temperature that the planet enjoys.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Biosequestration or carbon sequestration through biological processes affects the global carbon cycle.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide is a greenhouse gas that increases radiative forcing and contributes to global warming along with ocean acidification.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: As phytoplankton and forests are the main ways in which Gaia draws down greenhouse gases, particularly carbon dioxide, taking it out of the atmosphere, the elimination of this environmental buffering will see, according to Lovelock, most of the earth becoming uninhabitable for humans and other life-forms by the middle of this century, with a massive extension of tropical deserts.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide () is an important trace gas in Earth's atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide is naturally captured from the atmosphere through biological, chemical or physical processes.
