As humans burn fossil fuels and release greenhouse gases, those gases enter the atmosphere where they cause increases in global temperatures and climate consequences. But for many years scientists have known that not all of the carbon dioxide we emit ends up in the atmosphere. About 40% actually gets absorbed in the ocean waters.

The UN Oceans Conference planned for June 2017 aims to create a more coordinated global approach to protecting the world’s oceans from rising threats such as acidification, plastic litter, rising sea levels and declining fish stocks.

Australians are no strangers to hot weather. But for the past week large parts of the continent have suffered a heatwave of unusual length and intensity. Temperature records were beaten around the country.

Between 2030 and 2050, climate change is projected to cause about 250,000 additional deaths per year from heat stress, malnutrition and the spread of infectious diseases like malaria, according to the World Health Organization.

Last winter’s El Niño was in fact one of the most powerful climate events of the past 145 years. If such severe El Niño events become more common in the future as some studies suggest they might, the California coast — home to more than 25 million people — may become increasingly vulnerable to coastal hazards. And that’s independent of projected sea level rise.

In a study released today, U.S. Geological Survey scientists and their colleagues document how the 2015-16 winter featured one of the most powerful El Niño climate events of the last 145 years. Investigating 29 beaches along the U.S West Coast from Washington to southern California, researchers found that winter beach erosion was 76 percent above normal, by far the highest ever recorded, and most beaches in California eroded beyond historical extremes.

For the first time, researchers have developed a mathematical equation to describe the impact of human activity on the earth, finding people are causing the climate to change 170 times faster than natural forces.

Crazy warm winters haven’t pushed Arctic ice beyond a “tipping point.” Every ton of CO2 we don’t emit saves 32 square feet of it.

A year after tens of thousands of common murres, an abundant North Pacific seabird, starved and washed ashore on beaches from California to Alaska, researchers have pinned the cause to unusually warm ocean temperatures that affected the tiny fish they eat.
