The graph shows a timeline at the bottom and atmospheric carbon dioxide levels on the side. The levels are mostly the same for hundreds of years but rise sharply toward the end of the timeline that represents the last hundred years or so. Scientists at the American space agency, NASA, study climate change from direct temperature measurement. They report that two thousand five was the hottest year ever recorded.

These are all low mass and similar in size to Neptune in our own solar system. The planets orbit a star about forty–one light years from Earth. One light year is a distance of more than nine million million kilometers. The star is named HD six–nine–eight–three–zero. It has a little less mass than our sun. It is part of the star group Puppis, the constellation known as the Stern. The astronomers used a European Southern Observatory telescope in South Get more content on HelpWriting.net
