Indeed, the sea star's novel cooling strategy will be insufficient to deal with
the challenge of a warming ocean.
Not exact matches
They must also deal with a host
of challenges tied directly to the environment and potentially amplified by climate change, including
warming waters, increasing
ocean acidity and the spread
of diseases that can decimate shellfish stocks.
«
Ocean warming may well turn out to be the greatest hidden
challenge of our generation,» said Dan Laffoley, marine vice chairman
of the World Commission on Protected Areas at IUCN.
Original post The three Dalhousie University researchers whose 2010 analysis
of plankton trends and
ocean warming has been
challenged by other marine scientists have sent this reaction to last week's post:
Never before has it been possible for people from all over the world to access the latest information and collectively seek solutions to the
challenges which face our planet, and not a moment too soon: the year 2015 was the hottest in human history, and the Great Barrier Reef is suffering the consequences
of warming oceans right now.
They then looked at the
challenges that
warmer oceans delivered for crustaceans, molluscs, sponges, deep sea invertebrates, the
warm and cold water corals that provide habitat for one - fourth
of the
ocean's variety, the pelagic or surface - swimming fish, and the demersal or deep - sea denizens that live longer, reproduce more slowly and are thus less likely to evolve and adapt to changing conditions.
I've never
challenged the notion that, if it exists, greenhouse
warming of the atmosphere could lead to more heat being RETAINED by the
oceans, which is not nearly the same thing as a DIRECT transfer
of heat energy FROM the atmosphere, TO the
oceans.
The International Union for the Conservation
of Nature (IUCN) has published a study concluding that the continued
warming of the
oceans is the greatest hidden
challenge of our generation.
I think the appeal in engaging with SebastianH is that he actually believes that CO2 functions like a «blanket» in the atmosphere and thus
warms the
oceans, melts glaciers at their base, raises sea levels to catastrophic heights, acidifies the
oceans, kills off 30,000 species per year, browns the Earth (desertification), etc., and that he is so convinced
of the «rightness»
of his beliefs that he thinks anyone who disagrees must be insane, stupid, mathematically
challenged, a conspiracy theorist, etc..
Soaring
ocean temperature is «greatest hidden
challenge of our generation» The soaring temperature
of the
oceans is the «greatest hidden
challenge of our generation» that is altering the make - up
of marine species, shrinking fishing areas and starting to spread disease to humans, according to the most comprehensive analysis yet
of ocean warming.
«This means that the glaciers are reassuringly not exposed to the
warmest waters, but it makes projections more
challenging because the pathways
of the
ocean heat are narrow and more sensitive to fluctuations.»
For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence
of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition,
warming may cause reductions in the abundance
of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health
of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If
ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency
of early Chinook salmon migrations, making management
of the fishery by multiple user groups more
challenging.134
The comprehensive paper, entitled «Explaining
ocean warming: causes, scale, effects and consequences,» described the swift
warming of the seas as «the greatest hidden
challenge of our generation.»
These actions, alongside the support
of science in tackling the major
challenges in projecting the impacts
of ocean warming and climate change more generally, will help the insurance industry to avoid market failures and increase societal resilience.
The soaring temperature

Their predictions — based on an analysis
of natural cycles in water temperatures in the Pacific and Atlantic
oceans —
challenge some
of the global
warming orthodoxy's most deeply cherished beliefs, such as the claim that the North Pole will be free
of ice in summer by 2013.
