Mann (Penn State Univ.) is a well-known climatologist who specializes in the field of climate change. Toles is a Pulitzer Prize-winning political cartoonist with biting wit. The two have teamed up to produce a timely, slim (150 pages of text), illustrated volume that attacks those who deny facts and implications of anthropogenic climate change. Scientists have reached the consensus that humans are radically changing climate--the data and analyses have been thoroughly tested--and readers are presented with this information. The data and analyses are referenced in further detail so readers can methodically comprehend the issue. The potential for disastrous consequences (e.g., losing the world's coastal infrastructure, billions of refugees, conflict over increasingly scarce resources) is discussed. The work then explores US climate change denial, referencing the tobacco industry's "disinformation campaign" to delay public recognition of tobacco's health risks. The fossil fuel industry is mirroring this exact approach with climate change. The authors also contend that lavish contributions by the industry created a "Republican war on science"--essentially corrupting a political party. Delay in mitigating this threat (caused by Republican obstruction) may have catastrophic consequences. Summing Up: Recommended. All readers. --Malcolm K.
