A new study has warned that unless we mitigate current levels of carbon dioxide emissions, Western Europe and New Zealand could revert to the hot tropical climate of the early Paleogene period -- ...
To understand how global warming could influence future climate, scientists look to the Paleogene Period that began 66 million years ago, covering a time when Earth's atmospheric carbon dioxide levels ...
