Two items, both appearing recently in Yahoo News and then put into the same post on Twitter by someone I follow, allege opposite effects from the same cause. According to one story, which credits Live Science as its source, melting glaciers resulting from global warming might cause the earth to rotate faster. According to the other, which lists Reuters as its source, the melting of glaciers "appears to be causing a slight slowing of the Earth's rotation". Apparently, if sometime in the future, the earth's rotation has become either slower or faster, global warming will be blamed.
Read the stories at the two links above and decide for yourself.
