Reporting on the State of the Climate in 2016

International report confirms 2016 was third consecutive year of record global warmth

A new State of the Climate report confirmed that 2016 surpassed 2015 as the warmest year in 137 years of recordkeeping.

Major indicators of climate change continued to reflect trends consistent with a warming planet. Last year’s record heat resulted from the combined influence of long-term global warming and a strong El Niño early in the year. The report found that the major indicators of climate change continued to reflect trends consistent with a warming planet. Several markers such as land and ocean temperatures, sea level, and greenhouse gas concentrations in the atmosphere broke records set just one year prior.

These key findings and others are available from the State of the Climate in 2016 report released online today by the American Meteorological Society (AMS).

The 27th annual issuance of the report, led by NOAA National Centers for Environmental Information, is based on contributions from nearly 500 scientists from more than 60 countries around the world and reflects tens of thousands of measurements from multiple independent datasets. It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments located on land, water, ice, and in space.

The report’s climate indicators show patterns, changes, and trends of the global climate system. Examples of the indicators include various types of greenhouse gases; temperatures throughout the atmosphere, ocean, and land; cloud cover; sea level; ocean salinity; sea ice extent; and snow cover.

Editorial of the Week...

Street Fountains

Summers are getting hotter and street fountains can provide only so much relief. Credit Eric Gaillard/Reuters

“It’s Not Your Imagination: Summers Are Getting Hotter.” So read a recent headline in The Times, highlighting a decade-by-decade statistical analysis by climate expert James Hansen. “Most summers,” the analysis concluded, “are now either hot or extremely hot compared with the mid-20th century.”

So what else is new? At this point the evidence for human-caused global warming just keeps getting more overwhelming, and the plausible scenariosfor the future — extreme weather events, rising sea levels, drought, and more — just keep getting scarier.

In a rational world urgent action to limit climate change would be the overwhelming policy priority for governments everywhere.

But the U.S. government is, of course, now controlled by a party within which climate denial — rejecting not just scientific evidence but also obvious lived experience, and fiercely opposing any effort to slow the trend — has become a defining marker of tribal identity.

Quote of the Week...

According to the Army Corps of Engineers, 31 Alaskan communities face “imminent” existential threats from coastline erosion, flooding and other consequences of temperatures that are rising twice as quickly in the state as the global average. A handful – Kivalina, Newtok, Shishmaref and Shaktoolik – are considered in particularly perilous positions and will need to be moved.

“It was clear from the start of the Trump administration that there was no interest in helping Alaskan communities, particularly coastal communities, adapt to climate change,” said Victoria Hermann, president of the Arctic Institute.

“There’s now no liaison from Washington on the issue. The biggest loss has been momentum. It feels like the Obama administration was kickstarting something useful but now it has dropped dead.”

SkS Spotlights...

Established in 2011, The Arctic Institute is an independent, nonprofit 501(c)3 tax-exempt organization headquartered in Washington, D.C with a network of researchers across the world. We envision a world in which the diverse and complex issues facing Arctic security are identified, understood, and innovatively resolved. Rigorous, qualitative, and comprehensive research is the Institute’s core for developing solutions to challenges and injustices in the circumpolar north. 

The Arctic Institute’s mission is to help shape policy for a secure, just, and sustainable Arctic through objective, multidisciplinary research of the highest caliber. Our research agenda is constantly evolving to reflect a rapidly changing Arctic. Institute projects, publications, and events span the most pertinent security issues of the circumpolar region, developed by direct engagement and collaboration with young scholars, emerging regional actors, and northern communities. We provide data, analysis, and recommendations to policymakers, researchers, the media, and the interested public about circumpolar security challenges. Beyond our work, the Institute is building the future of Arctic research through partnerships with organizations across the globe.

We are a think tank for the 21st Century. Our network of multidisciplinary scholars work in North America, Scandinavia, and continental Europe and represent expertise in many different disciplines. Together, we are dedicated to research of and engagement in the many dimensions of Arctic security.

Climate Feedback Reviews...

Climate Feedback asked its network of scientists to review the article, Global Ocean Circulation Appears To Be Collapsing Due To A Warming Planet by Trevor Nace, Forbes, Aug 3, 2017

Three scientists analyzed the article and estimated its overall scientific credibility to be ‘high’.

A majority of reviewers tagged the article as: 

Review Summary

This article at Forbes describes a study on the possible influence of Arctic sea ice loss on recent changes to a key portion of ocean circulation in the Atlantic Ocean. This Atlantic Meridional Overturning Circulation (AMOC) transports heat around the North Atlantic, but could be slowing down as a result of climate change, with consequences for regional temperatures in Europe and eastern North America.

Scientists who reviewed the article found that it accurately summarized research on the topic of the AMOC. However, the headline used stronger wording than the article, stating that “global ocean circulation appears to be collapsing due to a warming planet”. That is misleading, as this research is analyzing a weakening of the circulation pattern, but not something as extreme as a “collapse”.

97 Hours: Michael Raupach 

 

Michael Raupach's bio page

Quote shortened from:

"There is overwhelming evidence that human-induced climate change is already real and will increase. Climate science shows what is needed to limit warming to about 2C, and restrict impacts on rainfall, extreme events, ecosystems and more: global greenhouse gas emissions have to be cut by around 60% by 2050 (80% for Australia) with continued decreases after that."

  1. SYD temp 20|C warmer than average, so absurd temps are coming not only to arctic but also elsewhere, in this case even to my backyard.

    Deniers will of course say that it's fine to have a warm suthern winter, no matter what the arguments. The arguments being: such anomaly can bring ecological disaster, e.g. vectors of tropical diseases.

  2. I've never seen Earth being prtrayed as sexy warrior woman as in today's poster and don't know what to think of it.

    I think it feels accurate because the planet is remarkably resilient (far more resilient than the civilisation that wants to destroy its ecosystems) and its long term negative feedbacks (rock weathering) will prevent runaway climate change.

    But I don't know what effect that image will have on an average selfish person, especially a silly denier.

    [JH] The woman in the Poster of the Week is Wonder Woman, a famous US comic book hero who has also been portrayed on TV and in movies. It's a good thing to have super heroes defending the Earth.

  3. As if by confirmation of my earlier post about super-warm southern winter:
