The calcite corals first achieved algal symbiosis in the Cambrian era, 550 million years ago, when CO2 concentration was 20-25 times today’s. The more delicate aragonite corals first evolved in the Jurassic era, 175 million years ago, when CO2 concentration was 12-15 times today’s. Both species not only throve on the higher partial pressures of CO2 but also survived the only period – 55 million years ago – when the global ocean was acid (pH < 7.0). For comparison, rainwater is pronouncedly acid at pH 5.4, while the oceans are pronouncedly alkaline at pH 8.0 or thereby. Read the rest of this entry »

In the words of Chua et al. (2013), “until recently, research into the consequences of oceanic uptake of CO2 for corals focused on its effect on physiological processes, in particular, calcification.” However, they note that “events early in the life history of corals are also likely to be vulnerable to changes in ocean chemistry caused by increases in the atmospheric concentration of CO2.” Focusing on these early life history events, Chua et al. thus set out to test “the effect of reduced pH on embryonic development, larval survivorship and metamorphosis of 3 common scleractinian corals from the Great Barrier Reef,” employing “4 treatment levels of pH, corresponding to the current level of ocean pH and 3 values projected to occur later this century.” Read the rest of this entry »

According to Raitsos et al. (2014), “changes in phytoplankton dynamics influence marine biogeochemical cycles, climate processes and food webs, with substantial social and economic consequences,” and they add that large-scale assessments of phytoplankton biomass have been obtained from two different remote sensing satellites, the Coastal Zone Color Scanner (CZCS, 1979-1986) and the Sea-viewing Wide Field-of-view Sensor (SeaWiFS, 1998-2010). However, they note that “due to the large gap between the two satellite eras and differences in sensor characteristics, comparison of the absolute values retrieved from the two instruments remains challenging.” Rising to meet on that challenge, and employing a unique in situ ocean color dataset that spans more than half a century, in the present work Raitsos et al. merged the two satellite-derived chlorophyll-a (Chl-a) histories to produce a six-decade-long history of phytoplankton productivity over the Northeast Atlantic Ocean and the North Sea.

Oil Price Drops on Oversupply

 By STEVE AUSTIN

In June of 2014 the Brent Crude Oil Price hit $115 per barrel and many oil market insiders were predicting higher prices. Other analyst however, called a peak, and their predictions proved to be correct. By the beginning of October 2014, the Index dropped to $95 and predictions of further falls down to $90 or even $80 hold sway. What changed?

Panic

Back in June, the world suddenly became aware of the Muslim fundamentalist group called IS. This band of revolutionaries threatened to disrupt Iraq’s oil output, just as that country was beginning to open the taps and sell to the world. OPEC‘s estimates of world demand for oil showed that the loss of Iraq’s output would produce a large shortfall in supply. When supply cannot meet demand, prices rise. However, that simplistic view ignored many other factors that were coming into play in the oil market. Speculators talked the market up and encouraged panic buying. That panic pricing lasted long enough for those insiders heavily stocked with oil futures to offload them on the general public. Read the rest of this entry »

Coal likely to remain India’s energy focus as country battles for jobs

By Manipadma Jena

NEW DELHI (Thomson Reuters Foundation) – Investing in renewable energy could cost India jobs in the short run, warns a government report that could influence the direction of energy investment by India’s new jobs-focused administration.

The April report, from India’s Planning Commission, says that installing more wind and solar energy in the country, at a relatively higher cost than conventional energy, could in the short term slow the economy and cost jobs in traditional industries.

“Green energy will give jobs but will also displace those employed in the coal and transportation sectors,” Kirit Parikh, an economist who headed the expert group that produced the report on low-carbon strategies and “inclusive growth”, said at a media seminar in Delhi.

The Establishment Media Grows Skeptical Of Obama’s Climate Claims

September 29th, 2014

Is the establishment media finally getting tired of President Obama’s grandstanding on global warming? Some news outlets responded skeptically to Obama’s United Nations climate speech.

On Tuesday, Obama spoke before UN delegates in New York City, trying to rally countries to restrict fossil fuel use and cut carbon dioxide emissions. The speech was hailed by some in the media, but less warmly received by others.

An Associated Press “fact-check” of Obama’s speech found it to be a lot of “spin” on climate statistics, from his claims on U.S. emissions reductions to his supposedly “new” efforts to tackle global warming. Read the rest of this entry »

New Research Finds Earth Even Less Sensitive To CO2 Than Previously Thought

Research Used Data From This Year’s IPCC 5th Assessment Report

London, 25 September: A new paper published in the prestigious journal Climate Dynamics find that the effect of carbon dioxide emissions on global temperatures is likely to be even smaller than previously thought.

Earlier this year, in a widely discussed report for the Global Warming Policy Foundation, climate researcher Nic Lewis and science writer Marcel Crok put forward a new estimate of the Earth’s climate sensitivity based on observational data, finding that it was much less alarming than suggested by computer simulations of the Earth’s climate.

Now, Lewis and well known American climate science professor Judith Curry have updated the Lewis and Crok report estimates using the latest empirical data, a more sophisticated methodology and an approach to accounting for uncertainties that has been described by one independent reviewer as “state of the art”. Their findings fully support the modest estimates of climate sensitivity and future warming given in the Lewis and Crok report, and compared with that report make it look even less likely that the substantially higher estimates based on computer simulations are correct.

Sea Levels are not rising

NEW YORK (Thomson Reuters Foundation) – Protecting the infrastructure of American cities from the effects of climate change is rising on the agenda of the U.S. Department of Homeland Security, according to a top agency official.

“Increasingly, we’ve moved not only from a security focus to a resiliency focus,” said Caitlin Durkovich, assistant secretary for infrastructure protection at Homeland Security, an agency better known for its fight to curb terrorist threats.

Durkovich spoke Thursday on a panel at the Rising Seas Summit, a three-day conference organized by the U.S.-based Association of Climate Change Officers to discuss tools and ideas on building resiliency, particularly against rising sea levels. Read the rest of this entry »

New Study on the Cause of Global Warming Might ‘Take People by Surprise’

A new study suggests that the warming trend on the West Coast over the last century was not caused by human activity but more so by a change in the winds.

The research published in the journal Proceedings of the National Academy of Sciences acknowledged in the study significance that warming trends are “often ascribed to anthropogenic greenhouse forcing.” Using independent data from 1900 to 2012, researchers showed that the temperature change is “primarily attributed to changes in atmospheric circulation.”

This, they wrote, “presents a significant reinterpretation of the region’s recent climate change origins.” Read the rest of this entry »

Dying from Heat and Cold in Australia: With daily minimum temperatures rising so much faster than daily maximum temperatures all around the world, global warming – if it ever resumes after its nearly two-decade hiatus – should lead to less temperature-related mortality in most parts of the planet, as has historically been observed in Australia.

Modeling Daily Intense Rainfall Events over Africa: “State-of-the-art climate models still cannot realistically simulate daily intense rainfall events with high accuracy.”

Modeling Caribbean Precipitation: How Well Is It Being Done?: Both CMIP3 and CMIP5 models still have some perplexing problems that need to be resolved.

Dying From Heat in New York City: Petkova et al.’s discovery that the excess mortality originally experienced at high temperatures was substantially reduced over the course of the century they studied is indicative, in their words, of “population adaptation to heat in recent decades.” Read the rest of this entry »

Politically Left Scientist Dissents – Calls President Obama ‘delusional’ on global warming

Climate Statistics Professor Dr. Caleb Rossiter of American University: ‘Obama has long been delusional on this issue. Anyone who believes we are in a climate catastrophe I think is deluding themselves.’

Rossiter on his conversion to a climate skeptic: ‘You are very isolated on the Democratic Party on the left — one is, I am — for having this conclusion of analysis…I would say since 2004 I’ve been very lonely. I’ve been lonely working on the Hill for the Democratic Party.’

 Rossiter on Gore’s film: ‘I think it’s a wonderful teaching tool because it shows how we don’t do science. Gore’s irresponsible.’

On Gore winning the Nobel: ‘Worst Nobel Prize for peace since Henry Kissinger.’

Rossiter: ‘My blood simply boils too hot when I read the blather, daily, about climate catastrophe. It boggles the mind that I could be certain that I know what caused a half degree rise in the last hundred fifty years. It’s simply not large enough to find a physical cause.’

The Crumbling Climate-Change Consensus

September 23rd, 2014

by John Fund

The United Nations Climate Summit will begin in New York this Tuesday, but environmental activists didn’t wait. All day Sunday, they filled the streets of Manhattan for a march that featured Al Gore, New York City mayor Bill de Blasio, and various Hollywood actors.

But they certainly didn’t act like a movement that was winning. There was a tone of fatalism in the comments of many with whom I spoke; they despair that the kind of radical change they advocate probably won’t result from the normal democratic process. It’s no surprise then that the rhetoric of climate-change activists has become increasingly hysterical. Naomi Klein, author of a new book on the “crisis,” This Changes Everything: Capitalism vs. the Climate, said, “I have seen the future, and it looks like New Orleans after Hurricane Katrina.” In her new book she demands that North America and Europe pay reparations to poorer countries to compensate for the climate change they cause. She calls her plan a “Marshall Plan for the Earth” and acknowledges that it would cost “hundreds of billions if not trillions of dollars.” But she has an easy solution on how to pay for it: “Need more money? Print some!” What’s a little hyperinflation compared to “saving the planet”? Read the rest of this entry »

Kerry: Climate change as urgent as ISIS, Ebola

Secretary of State John Kerry said the threats posed by climate change should be addressed with as much “immediacy” as confronting the Islamic State in Iraq and Syria (ISIS), and the Ebola outbreak.

During a meeting with foreign ministers on Sunday, Kerry said global warming is creating “climate refugees.”

“We see people fighting over water in some places. There are huge challenges to food security and challenges to the ecosystem, our fisheries and … the acidification of the ocean is a challenge for all of us,” Kerry said.

“And when you accrue all of this, while we are confronting ISIL and we are confronting terrorism and we are confronting Ebola and other things, those are immediate,” he added, using an alternate acronym for the terrorist group.  Read the rest of this entry »
