Idea

Eaarth is a book by Bill McKibben about climate change. The title refers to the Earth, which McKibben claims has been so substantially changed by human influence that a new name is in order: “let it be Eaarth.”

Content and Discussion

Preface

Bill refers to a book he wrote on global warming twenty years where he felt sadness, but today this has turned into fear as the evidence are all around. The [[global warming ] has altered the water cycle

Warm air holds more water vapor than cold. In arid areas this means increased evaporation and hence drought?. And once the water vapor is in the atmosphere it will come down.

and rainfall is up 7 % in the US and accelerating according to reference p.1. Flood damage is increasing. Data shows dramatic increases -20 % or more - in the most extreme weather events across the eastern US, the kind of storms that drop many inches of rain in a single day.

So McKibben claims that global warming is no longer a threat its a fact. It is also more concrete in poor part of the world as reported from oxfam:

Even if we now adapted the smartest possible curbs on carbon emissions, the prospects are bleak for hundreds of millions of people, most of them among the world poorest

so McKibben says we must understand the world we have created and how to engage globally and locally in how to live on it.

1. A New World

The first chapter is devoted to list of scientific evidence reported by researcher and evidence reported by the media, that temperatures have risen on earth, and that this already had a lot of impact. Let us recap some of the scientific ones.

He reports on the consequences of the fact that the global mean temperature has increased one degree Celsius:

A planet a real one, with melting poles and dying forests and a heaving corrosive sea, raked by winds, strafed by storms, scorched by heat. An inhospitable place.

Here is what Hartmund Aumann, NASA JPL team said about the report ref. 1.4:

For every degree Centigrade (1.8 degrees Fahrenheit) increase in average ocean surface temperature, the team observed a 45-percent increase in the frequency of the very high clouds. At the present rate of global warming of 0.13 degrees Celsius (0.23 degrees Fahrenheit) per decade, the team inferred the frequency of these storms can be expected to increase by six percent per decade.

4. Lightfully, Carefully, Gracefully

Bill McKibben describes the kind of civilization that could be able to survive climate change:

It’s a civilization with much less mobility, more localized and concentrated on getting all necessary goods from the neighborhood.

The internet, on the other hand, will help as a substitute to the kind of mobility and diversity that people grew accustomed to during the end of the 20th century.
