(Reuters) - Highly radioactive water seeping into the ocean from Japan's crippled Fukushima nuclear plant is creating an "emergency" that the operator is struggling to contain, an official from the country's nuclear watchdog said on Monday.

This contaminated groundwater has breached an underground barrier, is rising toward the surface and is exceeding legal limits of radioactive discharge, Shinji Kinjo, head of a Nuclear Regulatory Authority (NRA) task force, told Reuters.

Countermeasures planned by Tokyo Electric Power Co are only a temporary solution, he said.

Tepco's "sense of crisis is weak," Kinjo said. "This is why you can't just leave it up to Tepco alone" to grapple with the ongoing disaster.

"Right now, we have an emergency," he said.

LONDON - The first scientific analysis of probable human-to-human transmission of a deadly new strain of bird flu that emerged in China this year gives the strongest evidence yet that the H7N9 virus can pass between people, scientists said on Wednesday.

Research published in the British Medical Journal (BMJ) analyzing a family cluster of cases of H7N9 infection in eastern China found it was very likely the virus "transmitted directly from the index patient (a 60-year-old man) to his daughter."

Experts commenting on the research said while it did not necessarily mean H7N9 is any closer to becoming the next flu pandemic, "it does provide a timely reminder of the need to remain extremely vigilant."

Climate change is occurring 10 to 100 times faster than in the past and ecosystems will find it hard to adjust

The climate is changing at a pace that's far faster than anything seen in 65 million years, a report out of Stanford University says.

The amount of global temperature increase and the short time over which it's occurred create a change in velocity that outstrips previous periods of warming or cooling, the scientists said in research published in today's Science.

If global temperatures rise 1.5 degrees Celsius over the next century, the rate will be about 10 times faster than what's been seen before, said Christopher Field, one of the scientists on the study. Keeping the temperature increase that small will require aggressive mitigation, he said.

When would global warming destroy life on Earth? Study hazards a guess.

A runaway greenhouse effect – where a planet's atmosphere traps so much heat that temperatures rise to life-snuffing levels – may be easier to achieve than previously believed. And there may be more than one way to drive the increase.

Those are the implications of two recent studies looking at what planetary scientists describe as one of the fundamental processes that can render a planet uninhabitable.

Rising Sea Levels Could Submerge Substantial Parts of 1,700 U.S. Cities

Sea levels, as we know, are incredibly sensitive to rises in global temperatures. A study released earlier this month revealed that the increase of a mere degree celsius could lead global sea levels to rise by as much as two meters. But according to a new study published in the Proceedings of the National Academy of Sciences, the implications are especially grim for the US. At the current rate of carbon emissions, over 1,700 cities, including New York, Boston and Miami, will be “locked in” by greenhouse gas emissions by this century’s end.

Environmental Reporting Guidelines: Including Mandatory Greenhouse Gas Emissions Reporting Guidance

Wed, 2013-07-31 22:09 — Kathy Gilbeaux

submitted by Albert Gomez

gov.uk - June 12, 2013

This document is designed to help companies in complying with the greenhouse gas (GHG) reporting regulation, a requirement from the Climate Change Act 2008; and all organisations with voluntary reporting on a range of environmental matters, including voluntary GHG reporting and through the use of key performance indicators (KPIs).

World Solar Power Topped 100,000 Megawatts in 2012

Wed, 2013-07-31 18:44 — Kathy Gilbeaux

                            

earth-policy.org - by J. Matthew Roney - July 31, 2013

The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity needs of nearly 70 million people at the European level of use. While PV production has become increasingly concentrated in one country—China—the number of countries installing PV is growing rapidly.

Arctic Methane Time Bomb Could Have Huge Economic Costs

Increasing temperatures in the Arctic region are reducing sea ice cover and increasing the possibility of methane leaching from the sea bed

bbc.co.uk - by Matt McGrath - July 24, 2013

Scientists say that the release of large amounts of methane from thawing permafrost in the Arctic could have huge economic impacts for the world.

The researchers estimate that the climate effects of the release of this gas could cost $60 trillion (£39 trillion), roughly the size of the global economy in 2012.

The impacts are most likely to be felt in developing countries they say.

The research has been published in the journal Nature.

New research by Kerry Emanuel suggests that hurricanes will become more frequent and more intense

Very recently, a publication appeared by perhaps the world's best-known hurricane scientist, Dr. Kerry Emanuel of MIT. Dr. Emanuel combined global computer simulations with more regional simulations to look into the future at the evolution of storms. What he found was surprising.

Dangerous Global Warming Could Be Reversed, Say Scientists

Global warming could be reversed using a combination of burning trees and crops for energy, and capturing and storing carbon dioxide underground (CCS), according to an analysis by scientists. But experts cautioned that trying such an approach after temperatures had passed dangerous levels could be problematic, as climate change reduced the number of trees available for “bioenergy.”

The bioenergy and CCS method was the most cost-effective way of tackling carbon emissions, said the team at Chalmers University of Technology in Sweden, publishing their research in the journal Environmental Research Letters on Thursday.
