Continuing to burn fossil fuels at the current rate could bring atmospheric carbon dioxide to its highest concentration in 50 million years, jumping from about 400 parts per million now to more than 900 parts per million by the end of this century, a new study warns.
And if greenhouse gas emissions continue unabated beyond that point, the climate could reach a warming state that hasn’t been seen in the past 420 million years.
Some research suggests that, if humans burned through all fossil fuels on Earth, atmospheric carbon dioxide concentrations could hit 5,000 parts per million by the year 2400.
The new study speaks to the power of human influence over the climate. It suggests that after millions of years of relative stability in the absence of human activity, just a few hundred years of anthropogenic greenhouse gas emissions are on track to cause unprecedented warming.
If anyone has any questions left about what Donald Trump's energy plans will do to the climate, just read his brand new website GreatAgain.gov for clarity.
"The Trump Administration will make America energy independent. Our energy policies will make full use of our domestic energy sources, including traditional and renewable energy sources. America will unleash an energy revolution that will transform us into a net energy exporter, leading to the creation of millions of new jobs, while protecting the country's most valuable resources—our clean air, clean water, and natural habitats. America is sitting on a treasure trove of untapped energy. In fact, America possesses more combined coal, oil, and natural gas resources than any other nation on Earth. These resources represent trillions of dollars in economic output and countless American jobs, particularly for the poorest Americans."

The direct link between climate change threats and the duties of the secretary of state is strong. As droughts, floods, heat waves, and other symptoms of a warming world increase both in number and intensity—throughout the Middle East, Africa, Asia, the Arctic, Europe, and the United States—the next U.S. secretary of state will face urgent pressure to curb climate change and manage the effects of a warming planet that can no longer be avoided. Failure to do so will damage the global economy and destabilize an already wobbly security landscape, with potentially dire consequences for U.S. national security interests.
The next U.S. secretary of state must, as Secretary John Kerry has, protect U.S. foreign policy and security interests and demonstrate a track record of personal and diplomatic credibility. President-elect Donald Trump’s nominee for the job, former* ExxonMobil CEO Rex Tillerson, does not meet those qualifications.
Back-to-back severe bleaching events have affected two-thirds of Australia’s Great Barrier Reef, new aerial surveys have found.
The findings have caused alarm among scientists, who say the proximity of the 2016 and 2017 bleaching events is unprecedented for the reef, and will give damaged coral little chance to recover.
Scientists with the Australian Research Council’s Centre of Excellence for CoralReef Studies last week completed aerial surveys of the world’s largest living structure, scoring bleaching at 800 individual coral reefs across 8,000km.
It’s simply deplorable: For the first time in more than 100 years, the federal government could steal fragile, sacred land from Native American tribes and hand it over to the fossil fuel industry.
Utah Republican Reps. Rob Bishop and Jason Chaffetz along with Sen. Mike Lee recently introduced a bill that would strip away protections for 100,000 acres of Ute tribal lands to allow for oil drilling and uranium mining. The bill would also prevent President Obama from designating 18 million acres of unprotected land at Bears Ears a national monument.
This legislation is a massive giveaway to the oil and mining industry and an attack on the indigenous people who have lived on this land for more than 11,000 years. We must act now to stop this bill in its tracks.
