Pollution of the ocean by runoff from the land and the fouling of the air with carbon dioxide (which is warming the ocean and acidifying it) are accelerating and expanding the threats to the world's coastal waters.

Local pressures, in particular overfishing, destructive fishing, and pollution from nearby land - based human activity, are paramount, but global warming has caused increased bleaching and ocean acidification, which makes it harder for corals to grow, compounding the problems, the World Resources Institute (WRI) and 24 other organizations concluded in «Reefs at Risk Revisited,» an update of a 1998 report.

This is one way that warming oceans could be helping to shift Greenland's ice off the land and out to sea.

Sea levels have been rising worldwide over the past century by between 10 and 20 centimetres, as a result of melting land - ice and the thermal expansion of the oceans due to a planetary warming of around 0.5 degreeC.

The list is long and familiar: too much carbon dioxide warming the atmosphere and acidifying the ocean; too much land being cleared, leading to deforestation and desertification; overfishing causing crashes in one stock after another; and habitat destruction reducing biodiversity so drastically that some consider a sixth mass extinction to be under way.

«There is evidence for global warming on a number of levels, and the planet has been warming, the oceans have been taking up heat, sea levels have been rising, land snow has been melting, glaciers are melting, and all these other things, so the reality of global warming is uncontroversial.»

Understanding how carbon flows between land, air and water is key to predicting how much greenhouse gas emissions the earth, atmosphere and ocean can tolerate over a given time period to keep global warming and climate change at thresholds considered tolerable.

This study also offers a slice of pterosaur life history that is out of reach of fossil evidence, suggesting that the reptiles lived within easy access of warm thermal wind currents near open spaces of land or near the ocean.

Because the vast plateau at such altitudes absorbs a huge amount of solar radiation, the atmospheric layer above it in summer is much warmer than air at similar elevations over lower land or the oceans.

Launching on four legs, the pterosaur would have flapped its wings till it caught these small pockets of warm air rising from ocean or hot land, and then coasted easily on these for several hours.

Low - lying coastal regions like Chile's are subject to advection fog, where warm ocean air crosses a band of cold water before reaching land.

What scientists discovered in 2014 is that since the turn of the century, oceans have been absorbing more of global warming's heat and energy than would normally be expected, helping to slow rates of warming on land.

Studies of past climate changes suggest the land and oceans start releasing more CO2 than they absorb as the planet warms.

June — August 2014, at 0.71 °C (1.28 °F) higher than the 20th century average, was the warmest such period across global land and ocean surfaces since record keeping began in 1880, edging out the previous record set in 1998.

June 2013 tied with 2006 as the fifth warmest June across global land and ocean surfaces, at 0.64 °C (1.15 °F) above the 20th century average of 15.5 °C (59.9 °F).

According to the Land & Ocean Temperature Percentile map above, a region of coastal west Africa, part of Greece, northwestern Iran, much of the southern Philippines, and central and south central Australia were record warm for the period.

I expect the rate of warming to proceed at a steady pace, about one and a half degrees over land in the next 50 years, less if the oceans are included.

With ENSO - neutral conditions present during the first half of 2013, the January — June global temperature across land and ocean surfaces tied with 2003 as the seventh warmest such period, at 0.59 °C (1.06 °F) above the 20th century average.

This is the seventh consecutive season in which the globe (land and ocean) was record warm, starting with summer (Jun - Aug) 2014.

However, for the globe as a whole, surface air temperatures over land have risen at about double the ocean rate after 1979 (more than 0.27 °C per decade vs. 0.13 °C per decade), with the greatest warming during winter (December to February) and spring (March to May) in the Northern Hemisphere.

They are seen in warming of the oceans, the land surface, and the lower atmosphere.

The observed fact that temperatures increases slower over the oceans than over land demonstrates that the large heat capacity of the ocean tries to hold back the warming of the air over the ocean and produces a delay at the surface but nevertheless the atmosphere responds quit rapidly to increasing greenhouse gases.

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.

When all the heat accumulating in the oceans, warming the land and atmosphere and melting ice is tallied up, we see that global warming is still happening.

The observed patterns of warming, including greater warming over land than over the ocean, and their changes over time, are only simulated by models that include anthropogenic forcing.

Is it possible for climate effects to outpace ocean & land warming rates?

The former is likely to overestimate the true global SAT trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the SAT over the ocean is predicted to rise at a slightly higher rate than the SST.

«The reason for the layering is that global warming in parts of Antarctica is causing land - based ice to melt, adding massive amounts of freshwater to the ocean surface,» said ARC Centre of Excellence for Climate System Science researcher Prof Matthew England an author of the paper.
