Claim: When CO2 emissions are compared directly to CO2 levels, there is a strong correlation in the long term trends.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: However, the Stern report, like many other reports, notes the past correlation between CO 2 emissions and economic growth and then extrapolates using a "business as usual" scenario to predict GDP growth and hence CO 2 levels, concluding that: Increasing scarcity of fossil fuels alone will not stop emissions growth in time.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Both CO 2 and CH 4 vary between glacial and interglacial phases, and concentrations of these gases correlate strongly with temperature.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Direct data does not exist for periods earlier than those represented in the ice core record, a record that indicates CO 2 mole fractions stayed within a range of 180 ppm to 280 ppm throughout the last 800,000 years, until the increase of the last 250 years.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year (more than 2 ppm per year) from 1.1% per year during the 1990s is attributable to the lapse of formerly declining trends in carbon intensity of both developing and developed nations.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Further research has demonstrated a reliable correlation between CO 2 levels and the temperature calculated from ice isotope data.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There is also a close correlation between CO2 and temperature, where CO2 has a strong control over global temperatures in Earth history.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: "Coherence established between atmospheric carbon dioxide and global temperature".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
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): 0
Passage: An emission intensity (also carbon intensity, C.I.)

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: During the glacial cycles, there was a high correlation between CO 2 concentrations and temperatures.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: While the full implications of elevated CO2 on marine ecosystems are still being documented, there is a substantial body of research showing that a combination of ocean acidification and elevated ocean temperature, driven mainly by CO2 and other greenhouse gas emissions, have a compounded effect on marine life and the ocean environment.

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.
