«In the face of other challenges
like rising ocean temperatures, this can turn into a feel good story.»
Not exact matches
One possible scenario is that
rising temperatures may alter
ocean currents, depriving Europe of the Gulf Stream and making it more
like Labrador or Siberia.
Based on modeling results by the National Oceanic and Atmospheric Administration (NOAA), which predicted that Pacific
Ocean temperatures would
rise by 1 degree Celsius (2 degrees Fahrenheit) over the next 50 years, a Canadian and U.S. team of scientists examined the distributional changes of 28 species of fish including salmon, herring, certain species of sharks, anchovies, sardines and more northern fish
like pollock.
As
ocean temperatures rise and oceanic diseases proliferate, species
like sea stars struggle to survive, and scientists are looking for underlying causes.
Sightings
like Halpin's — that is, dolphins and other creatures
like swordfish and loggerhead turtles finding themselves out of their usual waters — may become more common as
ocean temperatures continue to
rise.
At that point in geological history, global surface
temperatures were
rising naturally with spurts of rapid regional warming in areas
like the North Atlantic
Ocean.
Right now, 93 % of the reef is affected by coral bleaching due to environmental changes
like the
rising temperature of the
ocean water.
And guaranties that the cited above G8 deal is dead on arrival... Not that the deal will change anything, except for UK government which has been fantastic on Carbon reductions, The Senator and acolytes would have trouble explaining the disappearing Arctic
Ocean ice, not that someone is capable of «Hoaxing» vanishing multi year ice, and even further, failing to match their statements with Polar ice disappearing in tandem with world wide
temperatures being flat, not
rising for ten years now, as they
like to claim, how to explain the disappearing ice then??? Those trying to explain a long term cycle, beware!
Paul S (# 1)-- Since the Planck Response dominates over positive feedback responses to
temperature, wouldn't a La Nina -
like failure of surface
temperature to
rise lead to an increase rather than a reduction in energy accumulation compared with accumulation during a surface warming — presumably a small increase, so that the observed
rise in
ocean heat content would still be substantial?
Taking into account a number of variables that could accompany
temperature rise,
like changes to the atmosphere and
oceans, they found that August and September would be ice - free in the Arctic with a doubling of CO2, which they wrote could happen by the middle of the 21st century.
Like dozens of previous assessments their report concluded that human activities were, «causing surface air
temperature and subsurface
ocean temperatures to
rise.»
It means hotter global
temperatures, more extreme weather events
like heatwaves and floods, melting ice,
rising sea levels and increased acidity of the
oceans.
On the face of it, for the layman,
temperature rises causing CO2 to come out of the
ocean, with no feedback effect, seems
like a perfectly reasonable explanation.
Case in point: you point out how a CENTURY of global warming is borne out in the atmosphere, the cryosphere, the
ocean temperature, and in sea level
rise ALL YOUR OPPONENT needs to say is that the last 18 years doesn't look
like «warming» for the atmosphere above 15,000 feet (which, btw, WHAT atmosphere?)
Driessen's blog piece is in stark contrast to the views of climatologists including Michael E Mann, who said that climate change has indeed increased the severity of hurricanes
like Harvey due to factors
like sea level
rise attributable to climate change and increased
ocean temperatures.
Keep up the good work, I for one am sleeping better knowing you're debunking those climate change nutters, who, as far as I'm concerned, are probably just basing their conclusions on irrelevant things
like record summer
temperatures, melting ice - caps,
rising sea levels, weather chaos, increasing crop failures, species extinction,
ocean acidification... blah, blah, blah.
Christmas Island could also provide a glimpse at what the reefs of the future might look
like, should
ocean temperatures continue to
rise.
The reality is, CO2 within the
oceans evaporates out of it in warmer climates and the levels
rise,
like popping the top on a cold can of soda and then watching it go flat as the liquid heats to room
temperature.
As far as
rising ocean temperatures are concerned, I know studies (
like Barnett et al 2005) demonstrated there is an anthropogenic signal (if I am using the term correctly, meaning a discernable increase in
ocean temperature that is due to human activities) globally.
However,
ocean temperatures have warmed almost everywhere on the planet, with 0.5 ºC being the global mean
rise of sea surface
temperature, hence Trenberth's reasonable estimate that this much is the contribution from global forcings
like CO2.
