You probably aren't qualified to determine whether your brake pads need replacement, so you take your car to a mechanic (or two) for their professional assessment. Do you question the scientific modeling used to make that determination and immerse yourself in materials science and physics to verify it? No, you probably trust the science and pay to have your brakes replaced to keep you and your family safe.
Although the Earth's average surface temperature rose sharply by 0.9 degree Fahrenheit during the last quarter of the 20th century, it has increased much more slowly for the past 16 years
