In the aftermath of the 2015 pandemic of Zika virus (ZIKV), concerns over links between climate change and emerging arboviruses have become more pressing. Given the potential that much of the world might remain at risk ...

Lakes and reservoirs worldwide are increasingly experiencing depletion of dissolved oxygen (anoxia) in their bottom waters (the hypolimnion) because of climate change and eutrophication, which is altering the dynamics of ...

Rapid climate change is causing ecological disequilibrium in many parts of the planet, which makes restoration of natural ecosystems to predisturbance conditions less probable. An alternative to restored ecosystems may be ...

In recent years, global warming has been ignored and scientists producing evidence supporting this hypothesis have been denigrated and even investigated. However, as irrefutable evidence showing that global warming was a ...

Sustainable use of the planet is an attractive goal, especially concerning intergenerational ethics. However, a major ecological tipping point has been passed (e.g, melting glaciers) and, in the last three years, evidence ...

Persuasive evidence indicates that the biosphere is experiencing a major biotic crisis and even if humankind ceases stress on natural systems, the crisis will most likely disrupt or alter the surviving ecosystems. The new ...

Humankind has already passed the first climatic tipping point therefore engaging itself in a global experiment that has already reduced agricultural productivity. With the Artic ice melting 100 years ahead of IPCC prediction, ...

In the 20 years since Our Common Future was published, human population has grown exponentially, greenhouse gas emission has increased, hazardous materials increased, the number of species threatened by extinction has ...

Garrett Hardin s lifeboat metaphor is used to illustrate the problems of overpopulation and finite resources. Sea levels are rising due to excess atmospheric greenhouse gases that melt glaciers and warm the oceans. With ...

A positive feedback loop makes an existing process speed up while a negative feedback loop decreases the impact of an existing process. A source emits carbon dioxide and other greenhouse gases while a sink retain and stores. ...
