JAKARTA, Indonesia (AP) — U.S. Secretary of State John Kerry is putting climate change deniers in the same category as those who insist the Earth is flat.
Speaking in Indonesia today, Kerry says climate change may be the world's "most fearsome" weapon of mass destruction ther is and that urgent action is needed to combat it.
In a speech to Indonesian students, civic leaders and government officials in Jakarta, Kerry accused climate change deniers of using shoddy science and scientists to delay measures needed to reduce emissions of greenhouse gases.
He also argued that everyone and every country must take responsibility and act immediately.
Kerry argued that the cost of inaction to environments and economies will far outweigh even the significant expense of reducing greenhouse gas emissions that trap solar heat in the atmosphere and contribute to the Earth's rising temperatures.
A small patch of forest in St. Louis County could be a big part of understanding global climate change.
In November, the 60-acre plot at Washington University's Tyson Research Center near Eureka was named a Smithsonian Institution Global Earth Observatory. The St. Louis Post-Dispatch reports that the land between Lone Elk and West Tyson County Parks is now part of a network of 52 other forest plots scattered around the world being used to study climate change and biodiversity.
In part, the Smithsonian project is examining both how climate change affects forests and how forests affect climate change.
The Tyson plot is expected to provide a lot of information because scientists have been monitoring it since the 1980s and have collected data covering two of Missouri's worst droughts, 1988 and 2012. The latter was the worst on record.
STOCKHOLM (AP) - A landmark report by an international scientific panel says it's "extremely likely" that human activity is the dominant cause of global warming.
That's the strongest statement to date on the issue by the Intergovernmental Panel on Climate Change.
In its previous assessment, in 2007, the U.N.-sponsored panel said it was "very likely" that global warming was man-made.
It now says the evidence has grown thanks to more observations, a better understanding of the climate system and improved models to analyze the impact of rising temperatures.
The IPCC says a human footprint can be found in the warming of the atmosphere and oceans, in rising sea levels, melting snow and ice and in changes in some climate extremes.
