Sentences with phrase «with effects of ocean acidification»

To date, studies of aragonitic, scleractinian CWC responses to ocean acidification have frequently examined short - term acclimation, with effects on coral bio-mineralization, growth, and skeletal strength only becoming evident in experiments run for periods of a year or more (e.g., Tittensor et al., 2010).

Here, we tested the effects ocean acidification in combination with elevated temperature on early life history stages of several spawning acroporids from the Great Barrier Reef.

Connell, Sean; Kroeker, Kristy; Fabricius, Katharina; Kline, David; Russell, Bayden We explore how ocean acidification combines with complex environmental changes across a number of scales, highlight the multiplicity of factors and complexities that cause variation, and raise awareness of CO2 as a resource whose change in availability could have wide ranging community consequences beyond its direct effects.

While we might HOPE FOR THE BEST — that there will be a cooling trend (less sun irradiance, etc) to exactly counteract our AGW trend (even so there is the negative effects of CO2, even without the warming — ocean acidification, crop loss to weed, etc)-- we should then be trying to AVERT THE WORST with even more drastic GHG cuts.

Re # 13 With acidification of the oceans, the biggest issue is it's effects on ecosystems.

SRM on the other hand would merely mask temperature increases, with limited effects on ocean acidification, and would create novel climate regimes across significant areas of the world, with new patterns and levels of precipitation.

Science: While it is true that plants photosynthesize, and therefore take up carbon dioxide as a way of forming energy with the help of the sun and water, this gas is both a direct pollutant (think acidification of oceans) and more importantly is linked to the greenhouse effect.

David's late father - in - law was the pioneering scientist Charles David Keeling, who began to record the concentrations of CO2 in the atmosphere in the 1950s, and who shared with David science's predictions on the effects of persistent greenhouse gasses, including rises in mean temperature, disrupted weather patterns, wildfires, floods, strengthening tropical storms, ocean acidification, sea level rise, melting of glaciers and other effects.

Given that, if one wants freedom of choice and an efficient market, shouldn't one accept a market solution (tax / credit or analogous system based on public costs, applied strategically to minimize paperwork (don't tax residential utility bills — apply upstream instead), applied approximately fairly to both be fair and encourage an efficient market response (don't ignore any significant category, put all sources of the same emission on equal footing; if cap / trade, allow some exchange between CO2 and CH4, etc, based CO2 (eq); include ocean acidification, etc.), allowing some approximation to that standard so as to not get very high costs in dealing with small details and also to address the biggest, most - well understood effects and sources first (put off dealing with the costs and benifits of sulphate aerosols, etc, until later if necessary — but get at high - latitude black carbon right away)?

In addition, ocean acidification is co-occurring with other drivers of environmental change (including warming, eutrophication, hypoxia, eutrophication, pollution [12]-RRB-, yet the interactive effects and relative importance of multiple stressors on species physiology, life history and ecology, as well as species — environment interactions and ecosystem function remain poorly understood [13 — 17].

Despite variation in habitat, latitude and methods across studies, trends are emerging with respect to the effects of ocean acidification on echinopluteal growth and where sensitivities lie.

Ocean acidification can decrease the ability of marine organisms to build their shells and skeletal structures and kill off coral reefs, with serious effects for people who rely on them as fishing grounds.

Byrne et al. [61] characterize the stunting effect of ocean acidification on the arm growth response of echinoplutei larvae of 15 species of sea urchin from different climatic regions (tropical, temperate, polar) and with different bathymetric distributions (intertidal and subtidal).

In addition to changing larval size and form, ocean acidification has a negative effect on survivorship of echinoplutei, with a 10 — 20 % increase in mortality at pCO2 1000 + µatm [42].

Ocean acidification is accompanied by reduced availability of carbonate minerals, with negative effects on skeletogenesis, and by increased pCO2 that causes hypercapnia (increased organism pCO2) and altered metabolism [10 — 12].

Ocean acidification is often considered in terms of its direct negative effects on the growth and calcification of organisms with calcareous shells or skeletons.

My impression from looking at the conference material is that it was indeed more or less what you would expect four years on from the 2001 IPCC report, with two very large exceptions: The potential collapse of the West Antarctic Ice Sheet (= 5 meter sea level rise) and ocean acidification (= partial ocean ecosystem collapse with a subsequent cascade of potential side effects that practically defy description).
