A new Nature journal study on global warming has identified the climate tipping point. The results of this study, which indicate when changes to weather patterns become irreversible, are truly appalling.
To pinpoint the dates for when when cities and ecosystems around the world will experience hotter environments than ever before, the study utilized a variety of measurements. Maps, weather observations, almost 40 computer model simulations, data from observing hundreds of thousands of species and other specifics were used to calculate the tipping point at which every year will be warmer than the hottest year ever recorded over the past 150 years. The study noted that there is a five-year margin of error on the estimates.
For dozens of cities, particularly those near the equator, the tipping point dates are but a few generations away.
The earth has already seen glimpses of what its new environment will be like. In 2005, the world as a whole experienced it’s hottest year on record. The new study by Nature estimates that by the year 2047, every year that follows will likely be hotter than 2005.
“One can think of this year as a kind of threshold into a hot new world from which one never goes back,” said Carnegie Institution climate scientist Chris Field, who was not part of the study.
Tropics Swelter First
Unlike previous research, the study draws attention to the tropics rather than the polar regions. Currently, temperatures in the tropics vary minimally. A small increase in temperature could have devastating effects on these ecosystems that include coral reefs and rain forests. These equatorial regions hold the majority of earth’s biodiversity, and are already vulnerable due to deforestation and oil exploitation.
Michael Mann, a Pennsylvania State University climate scientist said that the research done by Nature “may be actually presenting an overly rosy scenario when it comes to how close we are to passing the threshold for dangerous climate impacts.”
Delaying the Tipping Point
The author of the Nature study, Camilo Mora, stated that he hopes this new data on climate change will motivate governments worldwide to take action before it’s too late.
The 2047 date for whole-world change is based on continual increase of greenhouse gas emissions from the burning of coal, oil and natural gas. If the world manages to reduce its emissions, the date could be pushed back to as late as 2069. For now, though, we are hurrying towards the 2047 date.
A Call to Action
Studies like this one by Nature can have a debilitating effect on us. It’s sometimes difficult not to feel hopeless when it comes to large and complex issues we care about like global warming.
At The Pachamama Alliance’s Awakening the Dreamer Symposium, we seek to move people from fear and resignation regarding issues such as global warming into possibility and opportunity for action. The focus of the Symposium is to wake people up to the imbalances and injustices in the world, and to give them tools to become effective activists.
Next week, we are celebrating our accomplishments as conscious investors in a environmentally sustainable, socially just and spiritually fulfilling world at our Annual Luncheon Fundraiser, which will be held in San Francisco on November 14.
At the luncheon, we will also be formally unveiling Up to Us, a new educational program that will help to empower and mobilize individuals to take action in defending the issues they care about.
We are very excited to share our new initiative with you, as we believe it is the next fundamental step in order for people to be empowered to shape the future of our planet.
