Current Global Warming Basics

Here is a summary of the basic impacts of global warming on our biosphere.  I present here the quick view.  More discussion at that site.

Atmospheric Temperatures

Here’s the global average temperature each month from January 1880 through January 2016, according to data from NASA:

The red dot marks the most recent value, January 2016. It’s the hottest yet.
Here is the secular trend:

I have discussed measuring the trend from 1998 to present here and here.  There can be no question atmospheric temperatures and rising.

NASA isn’t the only organization that tracks global temperature. There’s also the National Climate Data Center, the Hadley Centre/Climate Research Unit in the U.K., a modified form from the Univ. of York in the U.K., independent data from a team organized by researchers from Berkeley Univ. in California, and the Japan Meteorological Agency, just to name the best-known. It would be redundant to show you data from all these organizations, because they all tell the same story: l…

Best Places To Be With Global Warming Happening

I've posted before about the Pacific Northwest as being where you want to be while the planet is threatened by global warming.  I'm getting support from the Chief Strategist, TFIE Strategy Inc., an editor of The Future is Electric:
The Future is Electric is the house journal of TFIE Strategy Inc, a firm which assists global clients to future proof themselves in our rapidly changing world of business and technical innovation, and geopolitical and climate disruption. The article linked to provides a good summary of what we might expect much of which has been described in my posts to this blog.  Then he turns to assert where the best places to be are.  He names three locations on the planet, Chile, Poland, and, and...the Pacific Northwest

as I've believed all along.

Pacific Northwest — Northern coastal California, Oregon, Washington State and British Columbia. These places will typically see better weather than they see now: warmer in the summer and winter, more periodic rain…

Polar Vortex: More Winter Storms ahead for the Northeast

I've written about the polar vortex before.  It's balmy here in the Pacific Northwest, the warmest winter I can recall, but this year is another year for cold winter storms in the Northeast.  They've been hit hard this year so far, but it's not going to stop.

Brace for the Polar Vortex: It May Be Visiting More Often Find your long johns, break out the thick socks and raid the supermarket. After a month of relatively mild winter weather, the Midwest and the East Coast are bracing for what is becoming a seasonal rite of passage: the polar vortex.

It looks interestingly like the Arctic Circle weather just dumped itself over the East Coast of the U.S.

It’s this escaping polar air that is dropping temperatures in the Midwest and the East — there’s a lag time between the atmospheric event and when we experience the effects. The broken vortex is also sending icy temperatures to much of Europe in what some call the “Beast From the East.” [....]

The World My Grandchildren Will Inherit

I went to a presentation at the University of Washington by Professor Raftery of the Statistics and Sociology Departments of a recent paper of his and colleagues (Alec Zimmer, Dargan M.W. Frierson, Richard Startz, and Peiran Liu) in the Journal Nature, entitled Less than 2 °C warming by 2100 unlikely(link behind a paywall).

Their paper is a response to a need to provide a statistical forecast for global temperatures.  What the IPCC has previously provided are "scenarios" based on "expert" thinking.  Raftery has previously developed statistical methods for estimating world-wide migration patterns that has been adopted by the United Nations.  At the presentation he presented a statistical model for forecasting global temperatures.

Their result is a 90% interval forecast of 2 to 4.9 degrees Centigrade with a median of 3.2 degrees.
Their backtesting strongly supported the median.  He also said "that the data suggested that future improvements in carbon efficiency …

2018 Hottest Ocean Temperatures

Ocean temperatures actually matter more than atmospheric temperatures.
Last year was very likely the hottest year on record, according to the authors of a new study in the journal Science.  The study examined “multiple lines of evidence from four independent groups” measuring ocean heat and concluded “ocean warming is accelerating.” Researchers found the rate of warming for the upper 2,000 meters of ocean has increased by more than 50 percent since 1991.

As a result, “2018 is shaping up to be the hottest for the oceans as a whole, and therefore for the Earth,” a press release accompanying the study explains.  [....]
“While there still is time to do something to slow this process down, it is too late to stop serious global warming,” study co-author John Abraham, a professor of thermal sciences at the University of St. Thomas in Minnesota, told ThinkProgress,

Abraham warned that global warming “is happening faster than we previously thought.”

“For over a decade, more than 3,000 floats h…

global warming will soon destroy the internet

I've posted about sea levels many times.  The increasing sea levels is the first noticeable consequence of global warming.  But coastal real estate, cities like Miami and New Orleans, aren't the only things we'll notice.  We will also notice internet coverage

The findings estimate that within 15 years, thousands of miles of what should be land-bound cables in the United States will be submerged underwater. These cables bring us the internet, streaming movies, streaming television, streaming music.  It all could be gone with a few years.
The immediacy of the threat stems from an unfortunate coinciding of location — much of the infrastructure that supports the internet just so happens to be situated in places most prone to rising waters. Internet traffic from our devices pings through fiber optic cables bound up in tubes that lie in shallow trenches underground. Although these cables are designed to be weather-resistant, they were never meant to be waterproof, Barford say…

Nighttime Temps Rising Faster Than Daytime Temps

Nights Are Warming Faster Than Days. Here’s Why That’s Dangerous.

Nationwide, summer nights have warmed at nearly twice the rate of days, with overnight low temperatures increasing 1.4 degrees Fahrenheit per century since 1895, when national temperature records began, compared to a daytime high increase of 0.7 degrees per century. (Nights have warmed faster than days during other seasons, too.) As you can see from the plot, what appears to be small increases in global temperatures, 1.4 degrees Fahrenheit since 1895, has large consequences to weather.
In a typical year, heat waves kill more Americans than any other natural disaster including floods, tornadoes and hurricanes.

While warm summer nights may seem less concerning than scorching afternoons, “the combination of high daytime and high nighttime temperatures can be really lethal because the body doesn’t have a chance to cool down during the nighttime hours,” said Lara Cushing, professor of environmental epidemiology at San Franci…

Miami's Climate Gentrification

I've discussed Miami'sreal estate on a number of occasions.  What is happening there is reaching a new level, climate gentrification.
Miami residents welcome historic climate gentrification resolution.  Neighborhoods on higher ground are becoming more desirable. In what is being called the first of its kind, Mayor Francis Suarez quietly signed a resolution last month to address climate gentrification in Miami.

Climate gentrification is where lower rent neighborhoods are being invaded by people from the higher rent neighborhoods threatened by rising sea levels. 
Climate gentrification has been used to describe the phenomenon of wealthy residents relocating from once desirable locations along the coast, which are now vulnerable to climate impacts like sea-level rise, and moving to more secure locations. This in turn pushes out pre-existing communities, often lower-income people of color, many of whom are immigrants. Miami is trying to do something about climate gentrification.
