Ms Hoffman has been cold here in South Africa, Botswana, and Namibia. It is winter here... Even though it is July and so hot there in the USA. Why is it winter here and summer there?
The answer has to do with how the earth moves around the sun and how the earth is tilted. Look at the diagram.
See how one part of earth is always closest to the sun, either the north or the south? The place that is closest has summer. In June and July the northern part of the world (where the US is) is closest or has summer. At the same time, the south part of the world (where South Africa is) is farthest away has winter.
