Curry stresses the unknowns in climate science


Georgia Institute of Technology professor Judith Curry – currently demonized by climate change activists and championed by climate skeptics – zeroes in on the unknowns and the uncertainties in the science, E&E reports.

Climate week -- will it be remembered?

The week started out with a bang for the environmental movement, with a massive street march in New York City Sunday as world leaders gathered at the United Nations Climate Change Summit.

But it ended with the same questions that have dogged the debate for years, and no indication -- yet -- how a meaningful global post-2020 agreement will be reached late next year at the U.N. climate conference in Paris.

Climate summit reveals rocky road ahead for U.N. talks

UNITED NATIONS (AP) — President Barack Obama was the headliner at a marathon session of world leaders at the United Nations who promised to spend billions of dollars to take better care of the planet.

But none of the pledges made at Tuesday's one-day meeting -- the largest-ever gathering of world leaders to discuss climate -- was binding. And by the conclusion, the summit revealed the sharp differences that divide countries on matters such as deforestation, carbon pollution and methane leaks from oil and gas production.

Researchers see future crop problems

Researchers at the main campus of the University of Illinois, who are studying the impact climate change may have on food crops in the future, are seeing some potential problems, The New York Times reports.

China, US, India push world carbon emissions up

WASHINGTON (AP) — Spurred chiefly by China, the United States and India, the world spewed far more carbon pollution into the air last year than ever before, scientists announced Sunday as world leaders gather to discuss how to reduce heat-trapping gases.

The world pumped an estimated 39.8 billion tons (36.1 billion metric tons) of carbon dioxide into the air last year by burning coal, oil and gas. That is 778 million tons (706 metric tons) or 2.3 percent more than the previous year.

Global marches draw attention to climate change

NEW YORK (AP) — Tens of thousands of activists walked through Manhattan, warning that climate change is destroying the Earth — in stride with demonstrators around the world who urged policymakers to take quick action.

Most came on foot for the Sunday march, others with bicycles and walkers, and some even in wheelchairs. Many wore costumes and marched to drumbeats. One woman played the accordion.

DC faces major flood risk: Climate Central

By 2050 the Lincoln and Jefferson Memorials could end up as islands in a flooded Potomac River, under a scenario envisioned in a report issued by the Climate Central research group, according to The New York Times.

With biggest jump in decades, CO2 pollution levels hit annual record: UN

GENEVA (AP) — Carbon dioxide levels in the atmosphere reached a record high in 2013 as increasing levels of man-made pollution transform the planet, the U.N. weather agency said Tuesday.

The heat-trapping gas blamed for the largest share of global warming rose to global concentrations of 396 parts per million last year, the biggest year-to-year change in three decades, the World Meteorological Organization said in an annual report.

That's an increase of 2.9 ppm from the previous year and is 42 percent higher than before the Industrial Age, when levels were about 280 parts per million.

Study links polar vortex chills to melting sea ice

WASHINGTON (AP) — Remember the polar vortex, the huge mass of Arctic air that can plunge much of the U.S. into the deep freeze? You might have to get used to it.

A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of that cold air. Researchers say that's because of shrinking ice in the seas off Russia.

Normally, the polar vortex is penned in the Arctic. But at times it escapes and wanders south, bringing with it a bit of Arctic super chill.

Climate study yields bad news for tiny desert fish

RENO, Nev. (AP) — For 10,000 years, a tiny iridescent blue fish has lived in the depths of a cavern in Nevada's desert. But a new study says climate change and warming waters — and its lack of mobility — are threatening its existence and decreasing its numbers.

Scientists studying climate change anticipate that as Earth continues to warm, fish and wildlife will migrate away from the equator or seek higher ground for a cooler habitat.

"The catch phrase is 'Migrate, Adapt or Die,'" said Mark Hausner, a hydrologist at the Desert Research Institute in Las Vegas.
