The US government has released its final report on climate change, warning that climate change is creating new and dangerous hazards and that the US will have to clean coal country.
The government’s report to Congress is expected to be released next month.
It is a scathing assessment of climate science and the risks of climate inaction.
It says the US needs to reduce emissions of greenhouse gases to avoid the worst impacts of climate disruption.
The US Environmental Protection Agency (EPA) has already warned that the country is on the brink of a “climate emergency” and that it will need to do more to limit global warming.
The report is likely to be critical of President Donald Trump’s decision to withdraw the US from the Paris Agreement on climate action in November.
“The science has become clearer and the urgency of the problem is greater than ever,” said EPA administrator Scott Pruitt.
The agency released a second report on the climate emergency earlier this year.
It said that the risk of climate extremes is rising, and that “climate change is a driver of extreme weather events”.
It said “human activity is now the dominant driver of climate” and said that global temperature rises will likely exceed 2C, or 2 degrees Celsius.
The new report says that the United States faces a “serious risk of significant climate change” and the country “is likely to experience more extreme weather conditions than any other nation”.
“We know the impact of climate-related risks,” said Pruitt.
“We are going to see impacts that are not easily measured or predicted.”
It said the US must cut emissions to avoid a “catastrophic and irreversible” climate change and to protect the country from the risks posed by climate change.
It warns that climate disruption could increase costs to the US economy.
“Climate disruption is already costing the US the ability to protect people, the economy, and national security,” Pruitt said.
“Our economy is already impacted.
The economic consequences of the climate change are likely to get worse and worse before they are fully realized.”
The EPA has already issued a series of orders to limit emissions of methane and other greenhouse gases.
The reports also highlighted that climate-disrupting emissions are a significant contributor to the growth of CO2 in the atmosphere.
The EPA’s report is a significant departure from previous assessments by the agency.
A 2011 report by the EPA estimated that the costs of climate disruptions would exceed $6 trillion over the next century.
