Claim: At present, climate forecasts even as little as six weeks ahead can be diametrically the opposite of what actually occurs, even if the forecasts are limited to a small region of the planet.'

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: These uncertainties limit forecast model accuracy to about six days into the future.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: As proposed by Edward Lorenz in 1963, it is impossible for long-range forecasts—those made more than two weeks in advance—to predict the state of the atmosphere with any degree of skill owing to the chaotic nature of the fluid dynamics equations involved.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Mathematical models used to predict the long term weather of the Earth (climate models), have been developed that have a resolution today that are as coarse as the older weather prediction models.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Weather forecasting is the application of science and technology to predict the state of the atmosphere at a future time and given location.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: As proposed by Edward Lorenz in 1963, long range forecasts, those made at a range of two weeks or more, are impossible to definitively predict the state of the atmosphere, owing to the chaotic nature of the fluid dynamics equations involved.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: This article is about climate change scenarios.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Pressure tendency can forecast short term changes in the weather.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Basic knowledge of climate can be used within shorter term weather forecasting, for instance about climatic cycles such as the El Niño–Southern Oscillation (ENSO), the Madden–Julian oscillation (MJO), the North Atlantic oscillation (NAO), the Arctic oscillation (AO), the Pacific decadal oscillation (PDO), and the Interdecadal Pacific Oscillation (IPO).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: This is the opposite of the expected pattern if the Sun, currently closer to the Earth during austral summer, were the principal climate forcing.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The probability of abrupt change for some climate related feedbacks may be low.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The range in temperature projections partly reflects different projections of future greenhouse gas emissions.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Thus current evidence does not support globally synchronous periods of anomalous cold or warmth over this interval, and the conventional terms of "Little Ice Age" and "Medieval Warm Period" appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries.... [Viewed] hemispherically, the "Little Ice Age" can only be considered as a modest cooling of the Northern Hemisphere during this period of less than 1°C relative to late twentieth century levels.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: [clarification needed] Predictions measuring the effects of global warming on Australia assert that global warming will negatively impact the continent's environment, economy, and communities.
