Max Einstein: World Champions (Book 4)

Max finally meets her hero, Albert Einstein, as she dashes across glaciers, visits the Great Barrier Reef, and flies a solar-powered jet in a race to stop global warming - before it's too late for planet earth. So far, Max and her team of genius friends have solved problems that no one else could, including: bringing solar energy to remote locations, producing clean drinking water across the globe, and ending world hunger. No easy task, even for a genius! But now Max and her friends must take on their biggest challenge yet, something that affects every living creature on the planet. Max must figure out how to prevent climate change from destroying the earth. But sinister forces want to keep Max from succeeding, and this time, even the very foundation of the Change Makers Institute is threatened. Now Max must not only save herself and her friends, but the entire planet, too.
