Sentences with phrase «coastal land ice»

Not exact matches

Previous research suggests that, during the last ice age (which ended around 11,700 years ago), humans moved into the Americas from Asia across what was then a land bridge to North America, eventually reaching what is now the west coast of British Columbia, Canada as well as coastal regions to the south.

Faced by the loss of so much precious coastal land, it seems quite plausible that our descendants will resort to some kind of mega-project to cool the planet and stop the ice sheets melting.

Warming oceans and melting land ice have caused oceans to rise about seven inches since 1900, which has also led to more frequent coastal flooding.

These wildfires release soot into the atmosphere, which accelerates the rate of melting of glaciers, snow and ice it lands upon, which can lead to less reflectivity, meaning more of the sun's heat is absorbed, leading to more global warming, which leads to even more wildfires, not to mention greater sea level rise, which is already threatening coastal areas around the world.

Whether the storm was over land, ocean or coastal areas, clouds with more ice produced more lightning, researchers studying satellite radar images report in the journal Geophysical Research Letters.

Should coastal planners have concern over where land ice is melting?

A note of caution: To avoid erroneous ice concentration along coasts (satellite signal mixed from land and ocean), near coastal - areas have to be excluded.

For example, as a result of ice melting on land, such as from glaciers and ice sheets, as well as thermal expansion of the ocean, we have seen sea level rise 3.4 millimeters per year from 1993 - 2015, which puts coastal communities at risk of flooding and infrastructure damage.

Scientists are also confident that heating of the deep oceans and melting of land ice will lead to continued sea level rise, which will heighten the risk of coastal flooding and the severity of coastal hazards during stormy episodes.

If the «boxes» are so large that every land area is considered equal — how are coastal regions and ice - covered areas modelled as they change over the year?

Record - breaking temperatures, melting ice on land and sea, more frequent coastal flooding, prolonged droughts, and damaging storms are just some of the intensifying risks we face as our globe continues to warm.

Mean sea level (MSL) evolution has a direct impact on coastal areas and is a crucial index of climate change since it reflects both the amount of heat added in the ocean and the mass loss due to land ice melt (e.g. IPCC, 2013; Dieng et al., 2017) Long - term and inter-annual variations of the sea level are observed at global and regional scales.

«In the seventeenth century the coastal land around Breidamerkurjà ¶ kull was ice - free and farmed quite intensively by local people.

The report singles out coastal areas, including low - lying island nations, as hot spots of elevated risk that may not be completely manageable due to the steady climb in global sea levels projected to take place during the rest of this century, as the planet warms and land - based ice sheets melt.

These OMITTED / POORLY Represented processes include the following: oceanic eddies, tides, fronts, buoyancy - driven coastal and boundary currents, cold halocline, dense water plumes and convection, double diffusion, surface / bottom mixed layer, sea ice — thickness distribution, concentration, deformation, drift and export, fast ice, snow cover, melt ponds and surface albedo, atmospheric loading, clouds and fronts, ice sheets / caps and mountain glaciers, permafrost, river runoff, and air — sea ice — land interactions and coupling.

The fate of the ice sheets has a direct impact on populations worldwide: as the land - based ice melts, it raises sea level, and that can threaten coastal communities and economies.

Indigenous peoples have a distinctive and profound spiritual and material relationship with their lands and with the air, waters, coastal sea, ice, flora, fauna and other resources.
