Climate Scientists: We’re Alarmed. Here’s Why You Should Be, Too.

“Climate Scientists: We’re Alarmed. Here’s Why You Should Be, Too.“
This week, the world’s largest general scientific society, the American Association for the Advancement of Science, has issued an uncharacteristically blunt call to action on climate change. The must-read new report by the AAAS’s Climate Science Panel, “What We Know” has several simple messages:
We are as certain that humans are responsible for most recent climate change as we are that cigarettes kill:
Climate scientists agree: climate change is happening here and now.Based on well-established evidence, about 97% of climate scientists have concluded that human-caused climate change is happening….
The science linking human activities to climate change is analogous to the science linking smoking to lung and cardiovascular diseases. Physicians, cardiovascular scientists, public health experts and others all agree smoking causes cancer. And this consensus among the health community has convinced most Americans that the health risks from smoking are real. A similar consensus now exists among climate scientists, a consensus that maintains climate change is happening, and human activity is the cause.
What kind of change is already happening?
Average global temperature has increased by about 1.4˚F over the last 100 years. Sea level is rising, and some types of extreme events — such as heat waves and heavy precipitation events -– are happening more frequently. Recent scientific findings indicate that climate change is likely responsible for the increase in the intensity of many of these events in recent years.
What is the danger of continued inaction?
