""If the average temperature of a large body of water increases, that's an enormous amount of heat content," says Andrew Rosenberg, a convening lead author of the National Climate Assessment's Oceans chapter. Ocean waters are becoming warmer and more acidic, broadly affecting ocean circulation, chemistry, ecosystems, and marine life. Rising sea surface temperatures have been linked with increasing levels and ranges of diseases in people and marine life. In this video, Rosenberg discusses how human-caused climate change is transforming the oceans that make up 70 percent of the Earth's surface."

"Another young creative mind working towards bettering our world. 19-year-old Boyan Slat has revealed his plans to the world regarding his Ocean Cleanup Array that could remove 7,250,000 tons of plastic waste from the world's oceans."

A clear change in salinity has been detected in the world's oceans, signalling shifts and an acceleration in the global rainfall and evaporation cycle. In a paper published today in the journal Science, Australian scientists from the CSIRO and the Lawrence Livermore National Laboratory, California, reported changing patterns of salinity in the global ocean during the past 50 years, marking a clear fingerprint of climate change.

"The cooling of eastern Pacific Ocean waters has been counteracting the warming effect of greenhouse gases. Our research, released today in Nature, shows this natural variability in ocean cycles is responsible for the "hiatus" in global warming over the last ten years or so."

"We challenge the reader, on Oceans Day, to join us in a one-month "plastic de-tox" commitment. Start by counting how many disposable plastic items you use in one day, and decide how many of them you could do away without compromising your quality of life in any significant manner."

"Warming oceans are affecting the breeding patterns and habitat of marine life, according to a three-year international study published today in Nature Climate Change. This is effectively re-arranging the broader marine landscape as species adjust to a changing climate. Scientific and public attention to the impacts of climate change has generally focused on how biodiversity and people are being affected on land."

Last week the world's atmosphere took a giant leap backward. For the first time in more than 3 million years, the atmospheric concentration of carbon dioxide (CO2) reached 400 parts per million. This was recorded at the National Oceanic & Atmospheric Administration's Earth System Research Laboratory located on Mauna Loa in Hawaii right out in the middle of the Pacific Ocean, a long way from major sources of CO2 in Asia and North America. What this means for the environment is uncertain but it's likely that, if no measures are taken to reduce this level of greenhouse gas, we could be headed for 3-4 degrees C warming globally by the end of this century

"But sea debris comes from both land and sea sources and it's hard to point to its exact origin and hence to get a polluter to take responsibility for cleaning it up."

"Ocean warming has already affected global fisheries in the past four decades, a new international study has found, driving up the proportion of warm-water fish being caught and posing a threat to food security worldwide."

We've made a new Coke ad -- with a twist! It exposes how this corporate giant is willing to let plastic pollution trash our oceans and kill our marine life. Chip in today to help get it on TV: http://bit.ly/cokead-YT

"The World Meteorological Organization just released its Global Climate Report (pdf), which wastes no time in announcing a stark truth. The report's first sentence: "The first decade of the 21st century was the warmest decade recorded since modern measurements began around 1850." Nine out of ten years between 2001 and 2010 were among the ten warmest in recorded history, according to the report, and the warmest year to date was 2010. For those worried about glacier melting, the heat spike wasn't isolated to land. The decade was warmest for both land and ocean surface temperatures. In case anyone still doubts the existence of global warming, take a gander at this chart:"

Coastal seagrass can store more heat-trapping carbon per square kilometre than forests can, which means these coastal plants could be part of the solution to climate change. Even though seagrasses occupy less than 0.2 per cent of the world's oceans, they can hold up to 83,000 tonne of carbon per square kilometre, a global team of researchers reported in the journal Nature Geoscience.

Australia has world class renewable energy resources across a range of technologies, from solar and wind through to hot rocks and oceans. We have what it takes to lead the world into a 100% renewable energy future.

"From record hot and cold temperatures to floods and droughts, 2013 was a wacky year for weather. The National Oceanic and Atmospheric Administration (NOAA) weighed in Wednesday with its list of the year's most significant climate anomalies and events. The report puts specific weather events into historical context, with the general effect of suggesting that global temperature rise is driving heightened weather extremes."

"Food and packaging waste is not simply something that 'goes away' when we pop it in the rubbish bin for collection by our garbos. Waste has an insidious, long-term impact on our environment, our wildlife and ultimately our own health. But how do we avoid it? In an age of excess consumption and a mindset of convenience-at-all-cost, is it possible to truly be waste free? The free-to-watch documentary shows how food and plastic waste can be avoided, drawing attention to much of the unnecessary packaging that is choking our lives, oceans and animals. It also gives an insight into the environmental and social impacts of our wasteful ways."

"The planet is building up heat at the equivalent of four Hiroshima bombs worth of energy every second. And 90% of that heat is going into the oceans. Right, now I've got your attention."

"One of the most common misunderstandings amongst climate change "skeptics" is the difference between short-term noise and long-term signal.  This animation shows how the same temperature data (green) that is used to determine the long-term global surface air warming trend of 0.16°C per decade (red) can be used inappropriately to "cherrypick" short time periods that show a cooling trend simply because the endpoints are carefully chosen and the trend is dominated by short-term noise in the data (blue steps).  Isn't it strange how five periods of cooling can add up to a clear warming trend over the last 4 decades?  Several factors can have a large impact on short-term temperatures, such as oceanic cycles like the El Niño Southern Oscillation (ENSO) or the 11-year solar cycle.  These short-term cycles don't have long-term effects on the Earth's temperature, unlike the continuing upward trend caused by global warming from human greenhouse gas emissions."

"The global conveyer belt is part of the large-scale ocean circulation that is driven by differences in the density of the waters. It plays a key role in keeping the climate at balance and Europe warm. Global warming may change it forever with unforeseeable consequences. "

"Published on 6 May 2015 This 2-minute "explainer" shows how tiny plastic microbeads are designed to go down the drain and into our rivers, lakes, and oceans and we can do to stop this ridiculous assault on our public waters. TAKE ACTION: http://bit.ly/banthebead"

"The University of Arizona is now running the Biosphere 2 facility that mirrors the different biomes of the Earth under a 3-acre enclosure. The facility includes a tropical rainforest, grassland savanna, saltwater ocean, mangrove wetland, and a farm. "
