Plastic Bottles
Plastic straws have become outcasts these days and for good reasons. But they are not the only bad actors in the world of plastic products. Single-use plastic water bottles are another example of a real trouble maker.
Rapid Response To Climate Change More Important Than Ever
The Intergovernmental Panel on Climate Change has issued a new report emphasizing the importance of taking rapid action to limit global warming to 1.5 degrees Celsius and examining the consequences of allowing temperatures to rise 2 degrees instead.

Sustainable Whaling?
The hunting of whales in the 19th and 20th Century nearly drove the giant mammals to extinction. By the 1960s, improved hunting methods and factory ships made it clear that whaling could not continue unchecked.
Drowning Atolls
The rising seas represent an existential threat to low-lying atoll islands and that threat now appears to the more imminent than previously thought.
An Accidental Plastic Eater
A couple of years ago, scientists in Japan discovered bacteria at a recycling plant that were breaking down a type of plastic called polyethylene terephthalate, or PET. With the world facing a growing plastic pollution problem, British and American researchers began to study the enzyme that the bacteria were using to try to understand how it works.
Another CO2 Milestone
The global concentration of carbon dioxide in the atmosphere was measured at 400 parts per million for the first time in recorded history in May of 2013. It was a brief event at the Mauna Loa Observatory in Hawaii at the time. Within the next couple of years, however, readings of at least 400 ppm became standard.
Electrifying Shipping Fleets
Container ships, tankers, freighters, and cruise ships are a significant source of carbon dioxide emissions and other pollutants. They currently account for 3% of global emissions – which doesn’t sound like much – but most other sectors such as power plants and automobiles are gradually decarbonizing. As a result, experts believe that shipping could account for as much as 17% of global emissions by the year 2050.
Rising East Coast Seas
Sea levels are rising around the world because of melting ice as well as warming waters since water expands as its temperature goes up. Average sea levels around the world are predicted to rise by about three feet by the end of the century as a consequence of the warming climate.
The Ocean As A Heat Sink
From 1998 until 2013, scientists observed a slowing in the rate of global mean surface warming. In other words, global temperatures were not rising as quickly as before. This quickly became known as the “global warming hiatus.”
Keeping A Pulse On Our Planet
The discovery of acid rain in North America was made possible by environmental data collected at a biological field station nestled in the White Mountains of New Hampshire. Hubbard Brook Experimental Forest is just one of the many biological field stations located around the globe that are keeping a pulse on the health of our planet.
Plastics And Our Oceans
Almost everyone everywhere comes into contact with plastics everyday. Their use has increased 20-fold in the past half-century, and production of the “ubiquitous workhorse material of the modern economy” is expected to double again in the next 20 years. Nearly one-third of all plastics are not properly disposed of or recycled.
The World’s Lakes Are Heating Up
Climate change is causing the world’s lakes to warm, with repercussions for fisheries and freshwater supplies. So reports an ambitious new study, funded by NASA and the National Science Foundation, and recently published in Geophysical Research Letters.
Climate Change And The Global Food System
One of the most troubling aspects of global climate change is its potential impact on the production, distribution and quality of food. A report issued at the 2015 Paris Climate Conference focused on identifying climate change impacts on global food security. Food security is the ability of people to obtain and use sufficient amounts of safe and nutritious food. Even without the impact of climate change, food security is a challenge because of increasing population, poverty, and changing eating habits.
