Sentences with phrase «near freezing point»

Under «well - mixed» conditions, this forces the near - surface temperature to be constrained to values near the freezing point of salt water, whether or not the associated land station is much warmer or colder.

The ocean surface temperature changes more slowly; the night - side ocean remains near the freezing point for the length of the simulation.

The temperature of the surface of the Arctic Ocean is fairly constant, near the freezing point of seawater.

Deep water (below 1000m)-- very cold water with temperatures near the freezing point.

(Within sufficiently fresh water near the freezing point, the sense of vertical heat flux is reversed between thermally direct and thermally indirect motion.)

Ozone depletion is therefore extremely sensitive to small changes in temperature when the stratosphere is near this freezing point.

Temps can plummet to the near freezing point for a few weeks during the depths of winter in late January and February.

This year the average temperature hovered near the freezing point — typical for the area — yet ice still disappeared at an accelerated pace.

Not exact matches

In other words, how can organisms resist pressures of a thousand atmospheres, temperatures near boiling or freezing point, or saturated salt brines?

An apparent lag in temperature seen in the Greenland ice cores might be an artifact of the proximity of the large Laurentide Ice Sheet, which would have limited the near surface air temperature to the freezing point, as happens over summer sea - ice now.

Meanwhile, a U.N. report predicted $ 1 trillion in annual damage from ocean acidification if carbon pollution is not curbed, and the Antarctic ice pack appears to have grown this year partly because fresh water from melting glaciers has raised the freezing point of the near - shore Southern Ocean.

RealClimate is wonderful, and an excellent source of reliable information.As I've said before, methane is an extremely dangerous component to global warming.Comment # 20 is correct.There is a sharp melting point to frozen methane.A huge increase in the release of methane could happen within the next 50 years.At what point in the Earth's temperature rise and the rise of co2 would a huge methane melt occur?No one has answered that definitive issue.If I ask you all at what point would huge amounts of extra methane start melting, i.e at what temperature rise of the ocean near the Artic methane ice deposits would the methane melt, or at what point in the rise of co2 concentrations in the atmosphere would the methane melt, I believe that no one could currently tell me the actual answer as to where the sharp melting point exists.Of course, once that tipping point has been reached, and billions of tons of methane outgass from what had been locked stores of methane, locked away for an eternity, it is exactly the same as the burning of stored fossil fuels which have been stored for an eternity as well.And even though methane does not have as long a life as co2, while it is around in the air it can cause other tipping points, i.e. permafrost melting, to arrive much sooner.I will reiterate what I've said before on this and other sites.Methane is a hugely underreported, underestimated risk.How about RealClimate attempts to model exactly what would happen to other tipping points, such as the melting permafrost, if indeed a huge increase in the melting of the methal hydrate ice WERE to occur within the next 50 years.My amateur guess is that the huge, albeit temporary, increase in methane over even three or four decades might push other relevent tipping points to arrive much, much, sooner than they normally would, thereby vastly incresing negative feedback mechanisms.We KNOW that quick, huge, changes occured in the Earth's climate in the past.See other relevent posts in the past from Realclimate.Climate often does not change slowly, but undergoes huge, quick, changes periodically, due to negative feedbacks accumulating, and tipping the climate to a quick change.Why should the danger from huge potential methane releases be vievwed with any less trepidation?

As we still slowly ascended... and the surface temperature of the soil fell to the freezing point the solar radiation became intenser... near the summit the temperature in a copper vessel, over which lay two sheets of plain window glass, rose above the boiling point of water, and it was certain that we could boil water by the solar rays in such a vessel among the snow fields.
