Global warming conspiracy theory is a collection of allegations that, through worldwide acts of professional and criminal misconduct, the science behind anthropogenic global warming has been invented and is being perpetuated for financial or ideological reasons. With all of the hysteria, all of the fear, all of the phony science, could it be that man-made global warming is the greatest hoax ever perpetrated on the American people,Global warming activists are as misguided as they are alarmist

Squids on the rise as oceans change
UNIVERSITY OF ADELAIDE
Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world’s oceans over the past 60 years, a University of Adelaide study has found.
The international team, led by researchers from the University’s Environment Institute, compiled a global database of cephalopod catch rates to investigate long-term trends in abundance, published in Cell Press journal Current Biology.
“Our analyses showed that cephalopod abundance has increased since the 1950s, a result that was remarkably consistent across three distinct groups,” says lead author Dr Zoë Doubleday, Research Fellow in the Environment Institute and School of Biological Sciences.
“Cephalopods are often called ‘weeds of the sea’ as they have a unique set of biological traits, including rapid growth, short lifespans and flexible development. These allow them to adapt to changing environmental conditions (such as temperature) more quickly than many other marine species, which suggests that they may be benefiting from a changing ocean environment.”
Dr Doubleday says the research stemmed from an investigation of declining numbers of the iconic Giant Australian cuttlefish.
“There has been a lot of concern over declining numbers of the iconic Giant Australian cuttlefish at the world-renowned breeding ground in South Australia’s Spencer Gulf,” Dr Doubleday says. “To determine if similar patterns were occurring elsewhere, we compiled this global-scale database. Surprisingly, analyses revealed that cephalopods, as a whole, are in fact increasing; and since this study, cuttlefish numbers from this iconic population near Whyalla are luckily bouncing back.”
Project leader Professor Bronwyn Gillanders says large-scale changes to the marine environment, brought about by human activities, may be driving the global increase in cephalopods.
“Cephalopods are an ecologically and commercially important group of invertebrates that are highly sensitive to changes in the environment,” Professor Gillanders says. “We’re currently investigating what may be causing them to proliferate – global warming and overfishing of fish species are two theories. It is a difficult, but important question to answer, as it may tell us an even bigger story about how human activities are changing the ocean.”
Cephalopods are found in all marine habitats and, as well as being voracious predators, they are also an important source of food for many marine species, as well as humans.
“As such, the increase in abundance has significant and complex implications for both the marine food web and us,” says Dr Doubleday.
