West Antarctic Ice Melt Poses Unique Threat to U.S.

Fri, 2018-06-15 21:52 — Kathy Gilbeaux

Sea level rise contributions from ice melt in different areas, including Greenland (a), West Antarctica (b), East Antarctica (c) and median of global glaciers (d). Values are ratios of regional sea level change to global mean sea level change. Adapted from Kopp et al. 2015.

News of Antarctica's accelerating ice melt garnered worldwide headlines yesterday, as scientists revealed that 3 trillion tons of ice has been lost to the sea since 1992 — mostly from the thawing West Antarctic Ice Sheet and Antarctic Peninsula.

Why it matters: The location of the ice melt is important for determining the future of coastal communities, according to climate scientists. And, due to West Antarctica melting, it turns out that the U.S. coastline will be hit extra hard . . .

Antarctic ice loss has tripled in a decade. If that continues, we are in serious trouble.

Antarctica’s ice sheet is melting at a rapidly increasing rate, now pouring more than 200 billion tons of ice into the ocean annually and raising sea levels a half-millimeter every year, a team of 80 scientists reported Wednesday.

Hurricanes Are Lingering Longer. That Makes Them More Dangerous.

A new study shows that storms are staying in one place longer, much like Hurricane Harvey did last year.

. . . A study published Wednesday in the journal Nature focuses on what is known as translation speed, which measures how quickly a storm is moving over an area, say, from Miami to the Florida Panhandle. Between 1949 and 2016, tropical cyclone translation speeds declined 10 percent worldwide, the study says. The storms, in effect, are sticking around places for a longer period of time.

Hurricanes Are Strengthening Faster Than They Did 30 Years Ago

With the start of hurricane season just three weeks away — and memory of last year's disastrous storms still fresh — scientists reported that powerful hurricanes are strengthening faster than they did 30 years ago.

Four of the monster hurricanes last year (Harvey, Irma, Jose and Maria) all intensified rapidly — when the maximum wind speed increases at least 29 mph within 24 hours . . .

. . . According to a study out this week, the main cause appears to be a natural climate phenomenon that warms the seawater where hurricanes typically intensify in the Atlantic.

How Storms, Missteps and an Ailing Grid Left Puerto Rico in the Dark

Mon, 2018-05-07 10:25 — Kathy Gilbeaux

A transmission tower and downed lines in the mountainous terrain of eastern Puerto Rico. Workers from the island and throughout the United States have worked to restore power after Hurricanes Irma and Maria last September.

It took months to restore electricity in Puerto Rico after hurricanes dealt a one-two punch. Many homes are still without power, and the system’s future is far from certain.

. . . After Maria and the hurricane that preceded it, called Irma, Puerto Rico all but slipped from the modern era . . .

. . . an examination of the power grid’s reconstruction — based on a review of hundreds of documents and interviews with dozens of public officials, utility experts and citizens across the island — shows how a series of decisions by federal and Puerto Rican authorities together sent the effort reeling on a course that would take months to correct. The human and economic damage wrought by all that time without power may be irreparable.

Earth's Carbon Dioxide Levels Continue to Soar, at Highest Point in 800,000 Years

Carbon dioxide — the gas scientists say is most responsible for global warming — reached its highest level in recorded history last month, at 410 parts per million.

This amount is highest in at least the past 800,000 years, according to the Scripps Institute of Oceanography. Prior to the onset of the Industrial Revolution, carbon dioxide levels had fluctuated over the millennia but had never exceeded 300 parts per million.

Wind and Solar Costs Continue to Drop Below Fossil Fuels. What Barriers Remain for a Low-Carbon Grid?

Fri, 2018-04-20 08:31 — Kathy Gilbeaux

Energy Innovation's Michael O'Boyle and Silvio Marcacci outline the barriers to high-penetration wind and solar in the least-cost era

The following is a viewpoint from Michael O'Boyle, electricity policy manager for Energy Innovation, and Silvio Marcacci, communications director for Energy Innovation

utilitydive.com - by Michael O'Boyle, Silvio Marcacci - March 21, 2018

Wind and solar are now cheaper than virtually anyone predicted, and renewable technologies have reached an inflection point: Rapid cost declines made renewable energy the cheapest available sources of new electricity, even without subsidies, in 2017. In many locations across America, building new wind energy projects is cheaper than running existing coal-fired power plants.

BRACED - Building Resilience and Adaptation to Climate Extremes and Disasters

Wed, 2018-04-18 09:50 — Kathy Gilbeaux

braced.org

BRACED is helping people become more resilient to climate extremes in South and Southeast Asia and in the African Sahel and its neighbouring countries. To improve the integration of disaster risk reduction and climate adaptation methods into development approaches, BRACED seeks to influence policies and practices at the local, national and international level.

Climate Change Is Complex. We’ve Got Answers to Your Questions.

Thu, 2018-04-05 08:21 — Kathy Gilbeaux

nytimes.com - By JUSTIN GILLIS Illustrations by JON HAN.

We know. Global warming is daunting. So here’s a place to start: 17 often-asked questions with some straightforward answers.

1. Climate change? Global warming? What do we call it?

Both are accurate, but they mean different things.

You can think of global warming as one type of climate change. The broader term covers changes beyond warmer temperatures, such as shifting rainfall patterns.
