3.5 Americans Create Enough Carbon Emissions to Kill 1 Person 0721 - 4,434 metric tonnes of CO2 yields 1 person dying this century from increased temperature.  904 deaths from operating a tyoical US coal power plant for 1 year.  Eliminating planet-heating emissions by 2050 would save an expected 74 million lives around the world this century.  It would take 3.5 Americans, 25 Brazilians or 146 Nigerians to kill 1 person.   -   take 1.  See take 2 below in the “Refugees” section.

Amid Summer of Fire and Floods, a Moment of Truth for Climate Action 0721 - June’s scorching temperatures, followed by a fast-moving wildfire, erased a Canadian town.  More than a million people are close to starvation amid Madagascar’s worst drought in decades.  In Siberia, 10s of 1,000s of square miles of forest are ablaze, potentially unleashing carbon stored in the frozen ground below.

The Uninhabitable Earth 0717

     This is a summary of many, many studies, across many facets of climate research.  It is based on interviews over the past several months with "the most credentialed and tenured scientists in the field, few of them inclined to alarmism and many advisers to the IPCC who nevertheless criticize its conservatism."  They "have quietly reached an apocalyptic conclusion, too: no plausible program of emissions reductions alone can prevent climate disaster.

The Unvarnished Truth about Climate Change 0817 - Tampa, Florida’s take on 0817 draft National Climate Assessment

Draft National Climate Assessment Finds Drastic Climate Change Impact on US 0817
    “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans.”
    “Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change….  There are no alternative explanations, and no natural cycles are found in the observational record that can explain the observed changes in climate. (Very high confidence)
    “Even if humans immediately stopped emitting greenhouse gases into the atmosphere, the world would still feel at least an additional 0.5°F (0.3°C) of warming over this century, compared with today.  The projected actual rise, scientists say, will be as much as 2°C.
