The human impact of climate change – 300,000 deaths per year, 2 in 3 of us already affected

A new report pulls together the current evidence on the current and projected human impact of climate change. It’s not pleasant reading. Headline numbers: Every year climate change leaves over 300,000 people dead. This will rise to roughly half a million in 20 years. 325 million people are seriously affected, and economic losses amount to US$125 billion, more than the total of all Official Development Assistance in a given year. Four billion people are vulnerable, and 500 million people are at extreme risk. These figures represent averages based on projected trends over many years and carry a significant margin of error. The real numbers could be lower or higher.

Over nine in ten deaths attributable to climate change are related to the gradual environmental degradation it causes (principally malnutrition, diarrhoea, malaria), with the remaining deaths being linked to weather-related disasters brought about by climate change.

Developing countries bear over nine-tenths of the climate change burden: 98 percent of the seriously affected people and 99 percent of all deaths from weather-related disasters (see map), along with over 90 percent of the total economic losses. The 50 Least Developed Countries contribute less than 1 percent of global carbon emissions.

  1. What you are saying is very true, although sad.
    What strikes me the most is that the struggle of climate change will be combated in developing countries.
    In many climate change debates, it is emphasized that adaptation and mitigation is the best way to go. Although this is not disagreeable, shouldn’t we do more?
    When one looks at this statistics that you just stated, it is striking, but also worthwhile to note that many developing countries scientist, are not given enough leverage when dealing with issues that impact them the most, such as climate change.
