You actually think the Earth's magnetic field keeps HEAT from the Earth? Oh, dear. Like Subwoofer said, if that were true, then summer wouldn't be a thing. Nor would life, actually.
And in case you didn't know, Earth's magnetic field is INCREDIBLY weak. That's why if you have a refrigerator magnet anywhere near a compass, it drags the needle towards your refrigerator magnet and away from Magnetic North. This is because the Earth's magnetic field is far, far weaker than you would probably think it is.
