Climate Change Affects Marine Fishes Through the Oxygen Limitation of Thermal Tolerance
It is shown in the eelpout, Zoarces viviparus, a bioindicator fish species for environmental monitoring from North and Baltic Seas, that thermally limited oxygen delivery closely matches environmental temperatures beyond which growth performance and abundance decrease, which will be the first process to cause extinction or relocation to cooler waters.
Climate change and temperature-dependent biogeography: oxygen limitation of thermal tolerance in animals

The capacity of oxygen delivery matches full aerobic scope only within the thermal optimum and at temperatures outside this range, only time-limited survival is supported by residual aerobic scope, then anaerobic metabolism and finally molecular protection by heat shock proteins and antioxidative defence.
Climate Change and Land: an IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems
The following errata have been identified and approved in accordance with the IPCC protocol for addressing possible errors in IPCC assessment reports, synthesis reports and methodology reports as…
Physiology and Climate Change
Studies of physiological mechanisms are needed to predict climate effects on ecosystems at species and community levels and to help scientists understand the drivers of climate change.

The conceptual analysis suggests that the relationships between energy turnover, the capacities of activity and other functions and the width of thermal windows may lead to an integrative understanding of specialization on climate and, as a thermal matrix, of sensitivity to climate change and the factors involved.
Contrasting futures for ocean and society from different anthropogenic CO2 emissions scenarios
The physics, chemistry, and ecology of the oceans might be affected based on two CO2 emission trajectories: one business as usual and one with aggressive reductions, consistent with the Copenhagen Accord of keeping mean global temperature increase below 2°C in the 21st century.
Effects of long-term moderate hypercapnia on acid-base balance and growth rate in marine mussels (Mytilus galloprovincialis)
Analysis of frequency histograms of growth rate revealed that hypercapnia caused a slowing of growth, possibly related to the reduction in metabolic rate and the dissolution of shell CaCO3 as a result of extracellular acidosis, confirming that a reduction in sea-water pH below 7.5 is harmful for shelled molluscs.
Ecosystem effects of ocean acidification in times of ocean warming: a physiologist’s view

Ocean warming and acidification occur at global scales and, in the case of temperature, have already caused shifts in marine ecosystem composition and function. In the case of CO2-induced ocean…
Biological Impact of Elevated Ocean CO2 Concentrations: Lessons from Animal Physiology and Earth History
Evaluated critical processes and the thresholds beyond which these effects may become detrimental are evaluated, in line with recent considerations of a detrimental role of CO2 during mass extinctions in the earth's history.
