Due to Global Warming, End Is Virtually Certain for NYC, Boston, Miami, Holland

A new article in the prestigious Proceedings of the National Academy of Sciences (PNAS), is headlined "The Multimillennial Sea-Level Commitment of Global Warming," and it reports that because of carbon emissions that are virtually certain, on the basis of the lack of policy-response to global warming thus far, sea levels are now set to rise anywhere from around 8 inches to 7 feet within 100 years, and around 5 yards to 10 yards within 2,000 years. The projections are clearer (within a narrower range) for the longer time-frame than for the shorter one. That's because even if the short-term consequences of heat-rise turn out to be relatively slight, the longer-term consequences are clearer, and will be considerably larger, as delayed impacts kick in.

Wind at parity with new coal in India, solar to join by 2018: HSBC

Thu, 2013-07-18 10:13 — Gina Angiola

By on 11 July 2013

Wind energy is now cost competitive with new-build coal capacity in India, and solar is likely to follow suit sometime between 2016-18, according to a report by HSBC.

The report on India Renewables, Good bye winter, hello spring, published on April 30, says the growing cost-competitiveness of renewable energy with new-build coal – and the arrival of wind parity, despite the upper wind FiT range being around 15 per cent lower than the upper tariff range for new coal capacity (see chart 3 below) – is helping to drive strong renewables growth on the sub-continent.

India’s share of renewable generation in the total electricity mix increased to around 6 per cent in the 2012/13 financial year – an amount the government is hoping to grow to 20 per cent by the end of 2020, to help meet the nation’s a peak power deficit of 12GW, or around 9 per cent of its demand....

Scientists Predicted A Decade Ago Arctic Ice Loss Would Worsen Western Droughts. Is That Happening Already?

Scientists predicted a decade ago that Arctic ice loss would bring on worse western droughts. Arctic ice loss has been much faster than the researchers — and indeed all climate modelers — expected (see “CryoSat-2 Confirms Sea Ice Volume Has Collapsed“).

It just so happens that the western U.S. is in the grip of a brutal, record-breaking drought. Is this just an amazing coincidence — or were the scientists right and what would that mean for the future? I ask the authors.

Climate Analog and Map Resources

To examine climate commonalities across the globe is called climate analog.  This is an extremely helpful tool in design work that I have used several times now that I have explored many of the world’s climates. For example, being able to grow Avocados next to Apples is possible and I have seen it at several places including coastal influenced places in New Zealand and Portugal.

Climate Change And The Nile: Floods From Major Rivers Around The World May Increase

Fri, 2013-06-21 18:45 — Maeryn Obley

huffingtonpost.com - June 9th, 2013

Climate change is likely to worsen floods on rivers such as the Ganges, the Nile and the Amazon this century while a few, including the now-inundated Danube, may become less prone, a Japanese-led scientific study said on Sunday.

The findings will go some way to help countries prepare for deluges that have killed thousands of people worldwide and caused tens of billions of dollars in damage every year in the past decade, experts wrote in the journal Nature Climate Change.

Given enough warning, governments can bring in flood barriers, building bans on flood plains, more flood-resistant crops and other measures to limit damage.

Introducing Global Sustainability

Sun, 2013-06-09 21:38 — Kathy Gilbeaux

I have long been deeply concerned about the effect our modern, highly industrialised approach is having on nature's capacity to sustain life on Earth. There is a growing set of alarming problems which, if not addressed with real urgency, will severely affect nature's capacity to keep her life support systems running and thus guarantee the well-being of billions of people around the world.

Climate research nearly unanimous on human causes, survey finds

A survey of thousands of peer-reviewed papers in scientific journals has found 97.1% agreed that climate change is caused by human activity.

Authors of the survey, published on Thursday in the journal Environmental Research Letters, said the finding of near unanimity provided a powerful rebuttal to climate contrarians who insist the science of climate change remains unsettled.

The survey considered the work of some 29,000 scientists published in 11,994 academic papers.

Climate Change: Human Disaster Looms, Claims New Research

Some of the most extreme predictions of global warming are unlikely to materialise, new scientific research has suggested, but the world is still likely to be in for a temperature rise of double that regarded as safe.

The researchers said warming was most likely to reach about 4C above pre-industrial levels if the past decade's readings were taken into account.

That would still lead to catastrophe across large swaths of the Earth, causing droughts, storms, floods and heatwaves, and drastic effects on agricultural productivity leading to secondary effects such as mass migration.
