Why Cold Snaps Don't Disprove Climate Change

Federal climate report warns of more weather 'weirding'

White House Says Dire Climate Report Based on 'Extreme Scenario'

President Donald Trump released his administration's report on climate change on Friday, which contradicted much of what he says about global warming and weather caused disasters.

Donald Trump has regularly expressed doubt about climate change - repeatedly claiming that it's a "hoax" - but the 1,700-page report, produced by scientists from 13 federal agencies, contradicts all of his environmental policies and almost every theory and proclamation he has made about climate science.

Thirteen federal agencies including the National Academy of Sciences, the Committee on Environmental and Natural Resources, and the National Science and Technology Council, along with university and commercial scientists were required by Congress to release the report, called the Fourth National Climate Assessment.

This week's United State report, although issued when most people were with their families and not paying attention, drew people to the reality of climate change.

She said the next climate assessment, which will be prepared over the next four years, will "provide for a more transparent and data-driven process that includes fuller information on the range of potential scenarios and outcomes". It details how global warming from the burning of coal, oil and gas is hurting each region of the United States and how it impacts different sectors of the economy, including energy and agriculture. In Alaska, the study envisions that a loss of sea ice will cause coastal flooding and force communities to relocate.

Earlier this week Trump tweeted about the cold weather hitting the East coast, asking the question, 'Whatever happened to Global Warming?'

Rush Holt, chief executive officer of the American Association for the Advancement of Science, said the economic warning shows that "policymakers can no longer afford to dismiss or ignore the overwhelming scientific evidence of climate change".

NASA to attempt hard Mars landing
The spacecraft will then send out two signals-one to say it has landed then another to confirm it was a successful touchdown. Here's a minute-by-minute look at the biggest moments of InSight's landing sequence - any of which could doom the robot.

The Defense Department is trying to understand what risk climate change poses to security.

The federal government report was released without fanfare Friday, when many Americans headed to the stores for the Black Friday sales. "That affects our jet stream pattern and counterintuitively might lead to more extremes on both sides - whether it be drought and flood, or cold and warm - because we get these higher amplitude wave patterns in the jet stream". The federal report reinforces these findings, although its focus is primarily on the US.

The 2018 National Climate Assessment addresses the change in temperatures globally, 'Over climate timescales of multiple decades. global temperature continues to steadily increase'.

The report, which is 1,600 pages long, isn't good news for the future of our planet-or the US economy.

The climate report was highlighted prominently on the home page of both the New York Times and the Washington Post from its release Friday until at least Saturday morning. The first part, released a year ago, says the only convincing explanation for climate change is human activity.

The report also reiterated the officials" concerns regarding the "greenhouse effect", the gradual warming of the Earth's atmosphere associated with the anthropogenic generation of carbon dioxide, methane, nitrous oxide and other so-called "greenhouse gasses'. The report is "contrary to his agenda, it's contrary to the interests that support this president", Levine said Friday on MSNBC.
