Sentences with phrase «threatened by ocean acidification»

There is growing concern over the decline of fisheries and the overall health of the ocean: scientists estimate that 90 % of stocks are fished at or beyond sustainable limits, habitats like coral reefs are threatened by ocean acidification, and large areas of ocean and coastlines are polluted.

Corals, shellfish, and other marine creatures made of calcium carbonate are threatened by ocean acidification, a consequence of rising atmospheric carbon dioxide levels increasing dissolved CO2 in the ocean.

The landmark environmental law has spurred significant progress but the nation's waterways now are threatened by sea - level rise and ocean acidification — unknown in 1972

This balance is threatened by increasing atmospheric carbon dioxide, which causes ocean acidification (decreasing ocean pH).

Focusing on reef - building corals and other shelled creatures that are threatened by increasing temperatures and ocean acidification, she is testing them to determine how species may acclimatize to the new circumstances.

Vital marine ecosystems are threatened by ocean warming and acidification, yet get a tiny fraction of climate finance, E3G research shows

Alarmed at the pace of change to our Earth caused by human - induced climate change, including accelerating melting and loss of ice from Greenland, the Himalayas and Antarctica, acidification of the world's oceans due to rising CO2 concentrations, increasingly intense tropical cyclones, more damaging and intense drought and floods, including glacial lakes outburst loods, in many regions and higher levels of sea - level rise than estimated just a few years ago, risks changing the face of the planet and threatening coastal cities, low lying areas, mountainous regions and vulnerable countries the world over,

Furthermore, from a global perspective, the carbon emissions from burning coal threaten the reef by accelerating ocean acidification and rising water temperature, which can lead to coral die - offs.

Recent research published by Elisabetta Erba in Science says corals are not threatened by lower pH. The study contradicts the assumption that ocean acidification leads to species die - offs, surprising scientists.

Damage to coral reefs from higher ocean temperatures and ocean acidification caused by higher atmospheric carbon dioxide levels, as well as damage from pollution and sedimentation, are threatening these breeding grounds for fish in tropical and subtropical waters.

The vulnerable nations declared that they are, «Alarmed at the pace of change to our Earth caused by human - induced climate change, including accelerating melting and loss of ice from Greenland, the Himalayas and Antarctica, acidification of the world's oceans due to rising CO2 concentrations, increasingly intense tropical cyclones, more damaging and intense drought and floods, including Glacial Lakes Outburst Floods, in many regions and higher levels of sea - level rise than estimated just a few years ago, risks changing the face of the planet and threatening coastal cities, low lying areas, mountainous regions and vulnerable countries the world over...»

Although it may lower the planet's temperature by a couple of degrees, it would do little to stop the acidification of the world's oceans that threatens coral reefs and other marine life.

Coral reefs are threatened by rising water temperatures, ocean acidification, and sea - level rise.3, 5 Coral reefs typically live within a specific range of temperature, light, and concentration of carbonate in seawater.6 When increases in ocean temperature or ultraviolet light stress the corals, they lose their colorful algae, leaving only transparent coral tissue covering their white calcium - carbonate skeletons.6 This phenomenon is called coral bleaching.

• Combined impacts: The combined impacts of ocean warming and acidification will increase the threat levels on more than half of all reefs by 2030, pushing the percentage of threatened reefs to more than 90 percent by 2030.

Around the world, marine environments are threatened by overfishing, warming waters, ocean acidification, and coastal development.
