Elsewhere in the oceans, the environmental changes during the PETM led to shifts in the distribution of plankton groups, with tropical species invading the high latitudes and high - latitude species dwindling in abundance.

There are fast feedback changes in some things (e.g. sea ice), and longer - continuing changes in other things (e.g. the Antarctic cap ice; ocean circulation; plankton species frequency and distribution; ocean pH; terrestrial rainfall and erosion).

Karl Schroeder: If there is any life on Earth in 100 years, I foresee either an ecological catastrophe, with the majority of species extinct, the oceans stagnant, the arctic and Antarctic desolate and lifeless, and billions of people living in complete ignorance of how things could be, in massive urban centres; or, a world in which climate change was solved early and completely through innovations in power generation and carbon sequestration, where agriculture has gone to vertical farming and North America has largely been rewilded back to forest and open prairie, and where extinct species are regularly recreated by genetic engineering and reintroduced.

We analysed responses of the calcifying larvae of sea urchins, an ecologically important group, to ocean change stressors in a synthesis of data from species from tropical to polar environments and from intertidal to subtidal habitats.

Just another thread (besides overfishing) which very likely changes life in oceans (species variety et al)!!!

I wonder, given the recent news about the various ways plankton actively affect the oceans, including churning the upper 100 meters, if any of the cycles could reflect big changes in which species predominate over time.

We don't have good information on the base of the food chain for most of the past — that's just «noise» but now that we start having ways to track trends in primary productivity — what's being made out of sunlight, water and CO2, by which organisms, and how fast do their populations change (remembering that some plankton populations turn over a new generation in a couple of weeks so relative numbers of different species can change that fast across the oceans).

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

The findings of a new hybrid species of shark goes to show just how versatile life can be in dealing with the ecosystem altering forces of climate change — proving yet again that within the depths of the world's oceans and its most keenly adapted inhabitants, there may be no shortage of natural marvels and awesome phenomena left to be discovered.

In the face of manifest climate change, the imminence of peak oil and peak natural gas, the increasing extinction of species, the pollution of the oceans and their consequent dead zones, and the population of the world continuing to grow, to see our pattern of consumption beyond our basic needs continuing... well it's quite disheartening.

In a 2002 report for the Navy on climate change and the Arctic Ocean, the Arctic Research Commission, a panel appointed by the president, concluded that species were moving north through the Bering Strait.

I think this paper, and a few others like it that have been published in recent years, indicate that the response of differernt coccolithophore species to changing CO2 is species dependent and more studies will be required to determine how these responses from different species might cause a shift in species abundances in the oceans and the ecosystem as a whole.

The news service reports, «Scientists believe climate change — the warming of oceans — has allowed some of the almost 2,000 jellyfish species to expand their ranges, appear earlier in the year and increase overall numbers, much as warming has helped ticks, bark beetles, and other pests to spread to new latitudes.»

By 2010 impacts long predicted were turning up, sooner than many had expected — acidification of the oceans, unprecedented deadly heat waves, record - breaking floods and droughts, heat - related changes in the survival of sensitive species.

Other aspects of global warming's broad footprint on the world's ecosystems include changes in the abundance of more than 80 percent of the thousands of species included in population studies; major poleward shifts in living ranges as warm regions become hot, and cold regions become warmer; major increases (in the south) and decreases (in the north) of the abundance of plankton, which forms the critical base of the ocean's food chain; the transformation of previously innocuous insect species like the Aspen leaf miner into pests that have damaged millions of acres of forest; and an increase in the range and abundance of human pathogens like the cholera - causing bacteria Vibrio, the mosquito - borne dengue virus, and the ticks that carry Lyme disease - causing bacteria.

Does it line up with our ocean data sets, our satellite data sets, boreholes and our 100s of records of changes in species behaviour and phenology.

Changes in species range and abundance were all attributed to Co2 climate change, but a thorough examination of each data set revealed false attribution due to limited historical context, cyclical changes due to ocean oscillations and landscape Changes in species range and abundance were all attributed to Co2 climate change, but a thorough examination of each data set revealed false attribution due to limited historical context, cyclical changes due to ocean oscillations and landscape changes due to ocean oscillations and landscape change.

«Those who work on the ocean day - to - day live with effects of small changes in climate, while observing the subsequent changes in habitat and species behaviors.

Whether it's CO2 emissions, temperature change, ocean dead zones, freshwater resources, vertebrate species or total forest cover, the grim charts virtually all point in the same dismal direction, indicating continued momentum toward doomsday.

The cumulative effect of environmental threats like climate change, ocean acidification and overfishing, brings the world's interconnected ocean close to a phase of extinction of marine species that is «globally significant» and unprecedented in human history, an international panel of marine scientists states.

But other elements could potentially also contribute to a collapse: an accelerating extinction of animal and plant populations and species, which could lead to a loss of ecosystem services essential for human survival; land degradation and land - use change; a pole - to - pole spread of toxic compounds; ocean acidification and eutrophication (dead zones); worsening of some aspects of the epidemiological environment (factors that make human populations susceptible to infectious diseases); depletion of increasingly scarce resources [6,7], including especially groundwater, which is being overexploited in many key agricultural areas [8]; and resource wars [9].

Previous research has shown that global warming will cause changes in ocean temperatures, sea ice extent, salinity, and oxygen levels, among other impacts, that are likely to lead to significant shifts in the distribution range and productivity of marine species, the study notes.
