Sentences with phrase «reached melting point»

Ice mass balance buoys deployed in the Beaufort Sea as part of the Office of Naval Research (ONR) Marginal Ice Zone Program indicate that surface temperatures have reached the melting point, at least intermittently, in the region, with some surface melt beginning in the southern part of the Beaufort, but little or no melt farther north (Figure 10), http://www.apl.washington.edu/project/project.php?id=miz.

Whereas it would take about 20 years for the warm permafrost regions to thaw under present climate change conditions, the paper says it could take just five years for that permafrost underneath the disturbed land to reach the melting point.

Not exact matches

The temperature at HD 189733b's hot spot might reach as high as 1700 degrees Fahrenheit, about the melting point of silver and roughly the same temperature as the furnaces used to cremate human remains.

REALITY: Wood fires, especially those that reach flashover, frequently exceed the melting point of metals..

3 Melted metals, such as doorway thresholds, indicate that a liquid fire starter must have been used in order to reach temperatures that exceed their melting points.

«As we reach a tipping point and see our customary water storage system, the snowpack, melting more and earlier in the winter, systems that rely on snowmelt will need to be reevaluated and modified.»

TIPPING POINT A new record of the Antarctic ice sheet's formation suggests that carbon dioxide levels in the atmosphere could soon reach a tipping point that will make the ice sheet more vulnerable to melPOINT A new record of the Antarctic ice sheet's formation suggests that carbon dioxide levels in the atmosphere could soon reach a tipping point that will make the ice sheet more vulnerable to melpoint that will make the ice sheet more vulnerable to melting.

If Earth reaches dangerous tipping points like the Antarctic glaciers melting, we'll have to engineer our way out of the crisis.

The temperature at the focal point may reach 3,500 °C (6,330 °F), and this heat can be used to generate electricity, melt steel, make hydrogen fuel or nanomaterials.

Hi, Basal sliding happens when the ice reaches pressure melting point.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

ScienceDaily (Oct. 3, 2008)-- Arctic sea ice extent during the 2008 melt season dropped to the second - lowest level since satellite measurements began in 1979, reaching the lowest point in its annual cycle of melt and growth on Sept. 14, according to researchers at the University of Colorado at Boulder's National Snow and Ice Data Center.»

I would add that we have already reached or even passed the tipping point, because the melting of the Greenland glaciers is accelerating and they will not stop melting unless the atmosphere cools.

Will we reach the point where the melting of the Greenland ice sheet is irreversible?

According to scientists, the melting of Earth's glaciers has reached a point of no return.

Well, it nearly * tripled * from mid February to late March, yet never reached above about 65 % of average at any point this season (and recent record warmth has already triggered melting; the snowpack is already back down to 55 % of average for the date).

These tipping points could be ice sheets on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and warming oceans push the release of methane from the sea floor, which could lead to runaway climate change, etc..

The likelihood of the complete loss of Arctic summer sea ice by 2030, faster melting of the vast Greenland ice sheets, and the rapid and quickening thaw of permafrost regions indicate that the window for arresting climate change before tipping points are reached is rapidly closing.

Of course the slow changing Milankovitch forcing can also emerge from the short - term noise over several millennia (or faster when ocean circulation or glacial - melt tipping points are reached).

Can we reach the political tipping point that will enable us to cut carbon emissions before we reach the point where the melting of the Himalayan glaciers becomes irreversible?

As I have pointed out in the «essay», what has happened (in an accelerating manner since 1246 CE) is that the insolation reaching far northern latitudes has increased during the first half of each year, and this should be anticipated to cause earlier and more - extensive spring melting of snow and ice, and therefore a progressively - earlier albedo reduction, and therefore more sunlight subsequently being absorbed across spring and summer: the ice albedo feedback effect acting positively (causing warming).

Greenland's ice melt is a key concern: If we reach a tipping point there, with a certain degree of warming, that could cause sea levels to rise and have irreversible impacts for the next millennium.

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?

We have moved with glacial slowness to reach the point where the Paris Agreement was possible, although the metaphor does not really apply anymore given the fast - melting nature of modern glaciers.
