Claim: The climate debate is, in reality, about a 1.6 watts per square metre or 0.5 per cent discrepancy in the poorly known planetary energy balance."

Passage: Watts Up With That features material disputing the scientific consensus on climate change, including claims the human role in global warming is insignificant and carbon dioxide is not a driving force of warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Between the start of the Industrial Revolution in 1750, and the year 2005, the increase in the atmospheric concentration of carbon dioxide (chemical formula: ) led to a positive radiative forcing, averaged over the Earth's surface area, of about 1.66 watts per square metre (abbreviated W m).

Passage: According to David JC MacKay, assuming that all future energy is derived from these thermal power stations operating with their present thermal efficiency of ~30%, and that the world population is 10 billion in 100 years time (~2100) with each individual enjoying a per capita energy usage rate similar to that of the average European standard of living of 125 kWh per day, the extra power contributed by this thermal energy use to the planet would be a global surface area average of 0.1 Watt per square meter, which is one fortieth of the 4 W/m that is believed to be likely if a doubling of atmospheric CO concentrations occur, and a little smaller than the "0.25 W/m effect" of Solar variations.

Passage: To quantify Earth's "heat budget" or "heat balance", let the insolation received at the top of the atmosphere be 100 units (100 units = about 1,360 watts per square meter facing the sun), as shown in the accompanying illustration.

Passage: Global warming contributes 0.6°C to this.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The total solar irradiance is measured by satellite to be roughly 1361 watts per square meter "(see solar constant)", though it fluctuates by about 6.9% during the year due to the Earth's varying distance from the sun.

Passage: Ignoring clouds, the daily average insolation for the Earth is approximately 6 kWh/m = 21.6 MJ/m.

Passage: In their 2014 report, the IPCC comparison of energy sources global warming potential per unit of electricity generated, which notably included albedo effects, mirror the median emission value derived from the Warner and Heath Yale meta-analysis for the more common non-breeding light water reactors, a -equivalent value of 12 g -eq/kWh, which is the lowest global warming forcing of all baseload power sources, with comparable low carbon power baseload sources, such as hydropower and biomass, producing substantially more global warming forcing 24 and 230 g -eq/kWh respectively.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The warming has not been globally uniform.
