Revised tallies confirm that the rate of sea level rise is accelerating as Earth warms and ice sheets thaw

scientificamerican.com - by Jeff Tollefson - July 19, 2017

The numbers didn’t add up. Even as Earth grew warmer and glaciers and ice sheets thawed, decades of satellite data seemed to show that the rate of sea-level rise was holding steady—or even declining.

Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year.

To Solve Climate Change, Solve Income Inequality

A new report says that the wider the gap between rich and poor, the more the environment suffers.

We often talk about how climate change exacerbates social and economic inequality, but rarely do we consider the opposite: that inequality itself can be a driver of climate change.

“What’s missing from the conversation is what our inequality crisis is doing to our planet,” said Susan Holmberg, a fellow at the Roosevelt Institute and author of a new report that shows how unequal societies inflict more environmental damage than more economically even societies. “One key topic that is still overlooked is how environmental degradation and climate change are themselves the toxic byproducts of our inequality problem,” Holmberg said.

Why a Warming Arctic May Be Causing Colder U.S. Winters

A new study shows how a warming Arctic could negatively impact regions thousands of miles away.

When a U.S. Republican senator threw a snowball onto the Senate floor in late February of 2015, he used it to underscore his belief that human-made climate change was an alarmist conclusion. The snowball had been rolled from the Capitol grounds in Washington D.C., which, at the time, was experiencing an uncharacteristically cold winter.

If global warming was real, he posited, how could the nation's capital experience such severe cold?

Uncharacteristically cold winters, however, just might be one of the most hard felt effects of climate change, according to a study published in Nature Geoscience by a team of researchers.

Carbon in Atmosphere Is Rising, Even as Emissions Stabilize

nytimes.com - by Justin Gillis - June 26, 2017

CAPE GRIM, Tasmania . . . For more than two years, the monitoring station here, along with its counterparts across the world, has been flashing a warning: The excess carbon dioxide scorching the planet rose at the highest rate on record in 2015 and 2016. A slightly slower but still unusual rate of increase has continued into 2017.

Scientists are concerned about the cause of the rapid rises because, in one of the most hopeful signs since the global climate crisis became widely understood in the 1980s, the amount of carbon dioxide that people are pumping into the air seems to have stabilized in recent years, at least judging from the data that countries compile on their own emissions.

That raises a conundrum: If the amount of the gas that people are putting out has stopped rising, how can the amount that stays in the air be going up faster than ever? Does it mean the natural sponges that have been absorbing carbon dioxide are now changing?

Earth's Sixth Mass Extinction Event Under Way, Scientists Warn

Researchers talk of ‘biological annihilation’ as study reveals billions of populations of animals have been lost in recent decades

           

Earth already in midst of sixth mass extinction, scientists say

CLICK HERE - RESEARCH - PNAS - Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines

theguardian.com - by Damian Carrington - July 10, 2017

A “biological annihilation” of wildlife in recent decades means a sixth mass extinction in Earth’s history is under way and is more severe than previously feared, according to research.

Scientists analysed both common and rare species and found billions of regional or local populations have been lost . . . 

 . . . “All signs point to ever more powerful assaults on biodiversity in the next two decades, painting a dismal picture of the future of life, including human life” . . .

Just 100 Companies Responsible for 71% of Global Emissions, Study Says

A relatively small number of fossil fuel producers and their investors could hold the key to tackling climate change

Just 100 companies have been the source of more than 70% of the world’s greenhouse gas emissions since 1988, according to a new report.

The Carbon Majors Report (pdf) “pinpoints how a relatively small set of fossil fuel producers may hold the key to systemic change on carbon emissions,” says Pedro Faria, technical director at environmental non-profit CDP, which published the report in collaboration with the Climate Accountability Institute.

When Will Electric Cars Go Mainstream? It May Be Sooner Than You Think

As the world’s automakers place larger bets on electric vehicle technology, many industry analysts are debating a key question: How quickly can plug-in cars become mainstream?

The conventional view holds that electric cars will remain a niche product for many years, plagued by high sticker prices and heavily dependent on government subsidies.

But a growing number of analysts now argue that this pessimism is becoming outdated. A new report from Bloomberg New Energy Finance, a research group, suggests that the price of plug-in cars is falling much faster than expected, spurred by cheaper batteries and aggressive policies promoting zero-emission vehicles in China and Europe.

Deadly Heat Waves Could Threaten 3 in 4 People By 2100

Even with aggressive reductions in carbon emissions, extreme heat is going to get worse, a new study has found.

huffingtonpost.com - by Chris D'Angelo - June 22, 2017

If humans fail to drastically cut carbon emissions, 3 in 4 people on the planet could be exposed to deadly heat waves by the end of the century, a new study has found. 

And even if countries take action to reverse climate change with aggressive emissions reductions, up to 48 percent of the global population will be plagued by at least 20 days of lethal heat per year by 2100. 

Camilo Mora, the study’s lead author and an associate professor of geography at the University of Hawaii at Manoa, told HuffPost that our “assault on the planet has been so massive” that we’ve left ourselves without a good option.

An estimated 2 billion people will be displaced from their homes by 2100 due to climate-driven rising seas, a new study says.

Roughly one-fifth of the world's population may become climate change refugees, according to Cornell University. The majority of those will be people who live on coastlines around the world, including about 2 million in Florida alone.
