The soils that encircle the northern reaches of the Arctic are a vast repository for carbon in the form of undecayed organic matter from dead vegetation. The enormous amount of material trapped in the permafrost contains enough carbon to double the current amount of carbon dioxide in the Earth’s atmosphere.
Public opinion about global warming is an important influence on decision making about policies to combat global warming and to be prepared for its consequences. An extensive polling effort by Yale University has produced an estimate of public opinions down to state, congressional district, and county levels.
Most of the world has accepted the analysis of the overwhelming majority of climate scientists that shows that our planet is warming and that our actions are the primary cause. However, some people – notably a number holding high office – reject this analysis. What exactly does it imply to say that climate change is not happening or is not caused by us?
Climate change is posing a major threat to the future of coral reefs. According to a recent United Nations-backed study, if swift action is not taken to curb greenhouse gas emissions, annual coral bleaching events will affect nearly all of the world’s coral reefs. And coral bleaching can result in serious coral mortality – as Australia’s Great Barrier Reef has recently illustrated.
A year ago, nearly 200 countries signed an agreement, known as the Paris Accord, to fight climate change by mitigating greenhouse gas emissions. They each promised to reduce their carbon output as soon as possible, and to do their best to keep global warming well below 2-degrees Celsius (or 3.6 degrees Fahrenheit).
Because of its Arctic location, Alaska is warming about twice as fast as the rest of the United States. The past year has been the warmest on record. The forces of erosion and increasingly powerful storms have resulted in the imminent risk of destruction for at least 31 Alaskan towns and cities. Many are predicted to become uninhabitable over the next few decades. Residents of these places are likely to join the growing flow of climate refugees around the globe.
As the oceans warm, many kinds of fish are on the move, seeking cooler and deeper water. Because of this, the fishing industry is struggling with antiquated regulations that are not moving as fast as the climate is changing.
We don’t experience climate; we experience weather. And a new study has found that what Americans believe about the changing climate often depends more on their personal experience than what is going on around the world.
Hundreds of thousands of reindeer roam Russia’s Yamal Peninsula, which is located in northwestern Siberia, and are herded by the indigenous Nenets people, reportedly among the Arctic’s last truly nomadic reindeer herders. Reindeer provide these indigenous people with transportation, food, clothes, and even tools made from their bones. Reindeer are well suited for the freezing temperatures and thick snow of this climate. But they are not well suited for climate change.
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.”
