There are numerous studies describing the impact of human-caused climate change on various ecosystems. (See my MET103 – Global Climate Change class notes and Impact of Climate Change web page for more information.) Now, a study just published in the peer-reviewed scientific journal Nature (Mora et al., 2013) tells us the timing of when ecosystems will be forced into an alien environment by human-caused climate change. For the world as a whole that year could be as early as 2034 (2047 ± 14 years). Imagine somebody telling you that New York could feel like an alien planet in 21 years. Just like species in nature, we would have to move, to adapt, or end up dead.
The full statement has been signed by 520 global scientists from 44 countries.
Earth is rapidly approaching a tipping point. Human impacts are causing alarming levels of harm to our planet. As scientists who study the interaction of people with the rest of the biosphere using a wide range of approaches, we agree that the evidence that humans are damaging their ecological life-support systems is overwhelming.
We further agree that, based on the best scientific information available, human quality of life will suffer substantial degradation by the year 2050 if we continue on our current path.
