Sentences with phrase «if ocean circulation changes»

The available data are insufficient to say if the changes in O2 are caused by natural variability or are trends that are likely to persist in the future, but they do indicate that large - scale changes in ocean physics influence natural biogeochemical cycles, and thus the cycles of O2 and CO2 are likely to undergo changes if ocean circulation changes persist in the future.

Not exact matches

And what we see is both how complex climate changes can be and how profound an effect changing patterns of ocean circulation can have on global climate states, if looked at on a geological time scale.»

«If you change the circulation, you change everything in the ocean,» said Menezes, a WHOI postdoctoral investigator and the study's lead author.

I would agree that unforeseen changes in ocean circulation could throw off model predictions, there are surely other wildcards too, but uncertainty like that is not your friend if you want to argue against avoiding climate change.

You've got the radiative physics, the measurements of ocean temperature and land temperature, the changes in ocean heat content (Hint — upwards, whereas if if was just a matter of circulation moving heat around you might expect something more simple) and of course observed predictions such as stratospheric cooling which you don't get when warming occurs from oceanic circulation.

If DO events are due to ocean circulation changes, what triggers these ocean circulation changes?

I would agree that unforeseen changes in ocean circulation could throw off model predictions, there are surely other wildcards too, but uncertainty like that is not your friend if you want to argue against avoiding climate change.

What if the mixing between the oceans were drastically reduced due to changes in ocean circulation?

The surface of the oceans are always warmer than the depths of the oceans > If you change the mixing efficiency, by shifting atmospheric circulations with solar precessional cycle for example, the mixing efficiency changes and the regions where precipitation falls changes.

Yes, afforestation of deserts (if it could be done) would increase the local temperatures and increase freshwater flow and thus reduce the salinity of the oceans and change circulation patterns.

«Greenland ice takes on a new role in the climate change story, not just indicating change and contributing to sea level rise, but possibly playing an important role in destabilizing regional if not global ocean circulation that naturally exchanges heat north - south,» said Jason Box of the Geological Survey of Denmark and Greenland, and a study co-author, in an email to Mashable.

How atmospheric and ocean circulation responds to various changes in forcing would need to be detailed if someone wanted to «prove» anthropogenic forcing is involved other than a minor increase in the average surface temperature.

Independent evidence from multiple sources suggest — if «real» — that recent warming was all cloud changes associated with decadal changes in ocean and atmospheric circulation.

Even if our emissions were the cause of increased atmospheric CO2 my Model still works because it reduces the effect of our CO2 to an infinitesinal circulation change compared to the much larger circulation changes induced by the variable sun and ocean cycles.

There are also other natural «modes of variability» which may be affected by a climate change, for instance if the heat transport in the oceans are to change (e.g. the Atlantic meridional overturning circulation AMOC).

They conclude with another warning: ``... if major shifts in sea ice cover and ocean circulation tip even large ice shelf cavities from cold to warm (35), there could be major changes in ice shelf and thus ice sheet mass balance.»

Here, we present an explanation for time - invariant land — sea warming ratio that applies if three conditions on radiative forcing are met: first, spatial variations in the climate forcing must be sufficiently small that the lower free troposphere warms evenly over land and ocean; second, the temperature response must not be large enough to change the global circulation to zeroth order; third, the temperature response must not be large enough to modify the boundary layer amplification mechanisms that contribute to making φ exceed unity.

an SR tweet: «And if the ocean circulation is sensitive to climate change, as is highly likely, will the currents respond abruptly and perhaps violently at some point, or will the transition be smooth?
