Climate change is reshaping our planet—not only in its physically measurable aspects, but also in terms of humanitarian challenges. Melting glaciers, rising seas, flooding, heat waves and the like are accompanied by human displacement and migration, changes in the occurrence of infectious diseases and—as highlighted by a recent study—the intensification of global economic inequality over the past half-century.

What are the emerging issues that will likely affect global diversity, ecosystem services, and conservation efforts in 2018? Results from the 9th annual horizon scan, conducted by 24 experts and described in a recently published study, identified early signs of the 15 top future challenges and trends related to themes that include new mechanisms driving the emergence and geographic expansion of diseases, innovative biotechnologies, reassessment of global change, and the development of strategic infrastructure to facilitate global economic priorities.

The 23rd conference of the United Nations Framework Convention on Climate Change was in full swing recently (6–17 November 2017). There, the countries that signed the 2015 Paris agreement discussed steps to keep the threat of climate change under control and—according to the Paris Agreement’s central aim—hold the rise in global temperatures to “well below” 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels by curbing industrial emissions of carbon dioxide. At the same time, scientists involved in the Global Carbon Project reported that total carbon dioxide emissions held stable from 2014 to 2016, at about 36 billion tons per year. They went on to clarify that this was a temporary hiatus that will end in 2017, and that economic projections suggest the likelihood of further emissions growth in 2018. Continue reading →
Air pollution not only threatens the future of our climate by significantly contributing to global warming, it also causes some of our most common illnesses, accounting for 1 in 8 deaths worldwide. It’s an invisible killer that is globally responsible for 36% of deaths from lung cancer, 35% of deaths from pulmonary disease, 34% of deaths from stroke, and 27% of deaths from heart disease, according to the World Health Organization (WHO).
The heat is on in the Arctic. This region is now warming at a rate faster than twice the global average—known as Arctic amplification. Consequently, the ice that covers the North Pole and surrounding areas, and melts to its lowest extent each September, has been disappearing at an alarming rate. Continue reading →

On April 15, 2015, at the University of Georgia, I wandered over to the Miller Learning Center to hear a talk by Dr. Steve McNulty (Link) with the United States Forest Service and the USDA Southern Regional Climate Hub (@SEClimateHub).
Let me start by saying this was one of the best and most effective climate communication talks that I have ever seen. It was so good that I felt compelled to write this blog to share some of it with you. Continue reading →

A new report by the Pew Research Center explores many ways scientists engage with the public – and why.
The study is based on a survey of more than 3,700 members of the American Association for the Advancement of Science. It reveals that scientists who study areas that are regularly debated in the media are more likely to engage in public outreach than those working in less controversial areas. They’re also more likely to speak with reporters and blog about their research. Continue reading →
