Every corner of the world’s oceans — from pole to pole and sea surface to seafloor — will undergo chemical changes associated with global climate change by 2100, jeopardizing the livelihoods of billions of people who subsist on marine ecosystems, according to a new study.
Previous studies addressing the effects of climate change on future ocean health have tended to focus on the effects of increased temperature and acidity on marine ecosystems. However, other oceanic conditions — including dissolved oxygen and productivity, or the abundance of tiny plant-like organisms that form the base of the marine food web — also play an important role in overall ocean health. As is the case on land, marine animals need oxygen and plant-life to survive. [Video: Humans Hit the Oceans Hard]
A team of 29 international scientists based at the University of Hawaii, Honolulu, have now developed more comprehensive projections of future ocean health, which take into account temperature, acidity, dissolved oxygen and productivity.

Not everyone is either worried or skeptical regarding man-made global warming. Mother Jones on how Monsanto is eagerly banking on it:
Data to help farmers grow crops in a changing climate. Climate Corporation, which Monsanto is acquiring, sells detailed weather and soil information to “help…manage and adapt to climate change.” Monsanto thinks the ag data business will be a $20-billion market.
Insurance for when it’s too hot, cold, dry, wet, or otherwise extreme outside. Climate Corporation currently sells both federally subsidized crop insurance and supplemental plans.
Drought-resistant corn. Monsanto lists the effects of climate change-related precipitation changes and droughts as a potential “opportunity.” This year, Monsanto started rolling out a new line of patented, first-of-its-kind genetically engineered corn seeds that are resistant to drought.
Cotton that needs less water to grow. The company is piloting genetically modified cotton that that can grow while using less water and survive drought.
“Last Hours” is the first in a series of short films that explore the perils of climate change and the solutions to avert climate disaster. Each subsequent film will highlight fact-based challenges facing the human race, and offer solutions to ameliorate these crises. The initial short film series will culminate in a feature film to be presented prior to COP21, the 2015 UN Conference on Climate Change in Paris.

A UN panel has released part one of its six-yearly update on the state of the Earth’s climate. The much-anticipated report by the Intergovernmental Panel on Climate Change (IPCC) says that with 95% certainty, humans are the dominant cause of global warming since the 1950s. The BBC News website’s science editor Paul Rincon breaks down some of the document’s key findings.
Part one of the IPCC’s fifth assessment report (AR5) on the Earth’s climate opens with the message that we are seeing changes in the climate system unprecedented in records spanning hundreds of years.
With this scene-setting out of the way, the report says the period from 1983-2012 in the Northern Hemisphere was likely the warmest 30-year period of the last 1,400 years. Each of the last three decades has got successively warmer, and these decades have all been warmer than any of the preceding decades since 1850.

An international panel of scientists has found with near certainty that human activity is the cause of most of the temperature increases of recent decades, and warns that sea levels could conceivably rise by more than three feet by the end of the century if emissions continue at a runaway pace.
The scientists, whose findings are reported in a draft summary of the next big United Nations climate report, largely dismiss a recent slowdown in the pace of warming, which is often cited by climate change doubters, attributing it most likely to short-term factors.
The report emphasizes that the basic facts about future climate change are more established than ever, justifying the rise in global concern. It also reiterates that the consequences of escalating emissions are likely to be profound.

Nathaniel Rich’s Odds Against Tomorrow is the latest in what seems to be an emerging literary genre. Over the past decade, more and more writers have begun to set their novels and short stories in worlds, not unlike our own, where the Earth’s systems are noticeably off-kilter. The genre has come to be called climate fiction — “cli-fi,” for short.
“I think we need a new type of novel to address a new type of reality,” says Rich, “which is that we’re headed toward something terrifying and large and transformative. And it’s the novelist’s job to try to understand, what is that doing to us?” As far as Rich is concerned, climate change itself is a foregone conclusion. The story — the suspense, the romance — is in how we deal with it.
Of course, science fiction with an environmental bent has been around since the 1960s (think J.G.

A team of researchers, led by Dr. Chris Huntingford from the Centre for Ecology & Hydrology, has discovered more evidence of rainforest resilience to global warming. Their findings reveal that tropical forests are less likely to lose biomass due to global warming than climatologists previously thought. According to the BIOMASS Energy Centre, biomass is biological material derived from living, or recently living organisms.
Researchers undertook the most comprehensive study yet of the risk of tropical forest dieback due to global warming. They contend that their results have significant implications for the role of tropical rainforests in the global climate system and carbon cycle.
Researchers utilized computer simulations with 22 climate models to examine the response of the tropical forests in the Americas, Africa and Asia to greenhouse-gas-induced climate change.
