Acidified ocean water found along US West Coast. San Francisco: A study of the California current system has found highly acidified water along the US West Coast.

The study led by Francis Chan, a marine ecologist at the Oregon State University (OSU), said conditions will continue to worsen due to the atmospheric carbon dioxide primarily to blame for the increase in acidification has been rising substantially, Xinhua news agency reported. Representational image. AP While findings of the study, which was published in the Nature Scientific Reports, identified "hotspots" of pH, or potential of hydrogen, measurements as low as any oceanic surface waters in the world, there were "refuges" of more moderate pH environments that could become havens for some marine organisms to escape more highly acidified waters.

"The threat of ocean acidification is global and though it sometimes seems far away, it is happening here right now on the West Coast of the US and those waters are already hitting our beaches," Chan said on Sunday. President Trump falsely claims the U.S. spends "billions and billions and billions" on the Paris climate accords.

President Trump falsely claims the U.S. spends "billions and billions and billions" on the Paris climate accords.

In his address, the president made the case that staying in costs American taxpayers exorbitant amounts of money. “We’re going to be paying billions and billions and billions of dollars,” Trump claimed in his Rose Garden announcement.

Problems continue to mount for the Commonwealth of Puerto Rico. The report says many municipal waters systems in Puerto Rico aren't tested regularly. Puerto Rico's Aqueduct and Sewer Authority is one of the many public agencies on the island struggling to provide services.

As humans put more heat-trapping gases into the atmosphere, like carbon dioxide, ice around the planet melts.

1.5 C vs 2 C global warming: New study shows why half a degree matters. European researchers have found substantially different climate change impacts for a global warming of 1.5°C and 2°C by 2100, the two temperature limits included in the Paris climate agreement.

The additional 0.5°C would mean a 10-cm-higher global sea-level rise by 2100, longer heat waves, and would result in virtually all tropical coral reefs being at risk. How climate change may drive extreme weather. —Whether a specific extreme weather event can be linked to climate change rarely gets a straightforward answer from climate scientists or meteorologists.

How climate change may drive extreme weather

It's complicated, they'll say, but that doesn't mean there isn't a relationship. "Climate scientists have been willing to link the general increase in certain types of weather extremes (heat waves, droughts, and floods) to climate change in a generic sense," says Michael Mann, an atmospheric scientist at Pennsylvania State University. Rising global temperatures and other climate forces can certainly change the conditions that underlie weather, which climate scientists have said can lead to a change in the frequency of a type of weather event.

Environmental Protection Agency (EPA), should have questioned Pruitt as the chief pediatrician for America's children. As head of the EPA Pruitt gets to decide what is safe for our kids—in the air they breathe, the water they drink, the food they eat and the communities they play. Senators didn't ask—but they are finding out. In his first big test of what kind of pediatrician he will be, Pruitt decided to reverse an earlier EPA decision to ban the pesticide chlorpyrifos, a potent nerve gas banned from household use years ago, but still used in farms, orchards, pastures and golf courses. GOP Vote to End Key Environmental Regulations. (WASHINGTON) — Moving to dismantle former President Barack Obama's legacy on the environment and other issues, House Republicans approved a measure Wednesday that scuttles a regulation aimed at preventing coal mining debris from being dumped into nearby streams.

Big Oil’s decades of deception: Report reveals that Exxon’s known the truth about climate science since 1981.

While evaluating the potential impact of developing a gas field it was interested in off Indonesia, ExxonMobil found one major reason for concern: the field in question was 70 percent carbon dioxide. If the field were developed, and that gas vented into the atmosphere, it could become the “largest point source of CO2 in the world,” accounting for a full one percent of climate change-causing emissions.

President Trump’s executive order will tell the EPA to begin rewriting the 2015 regulation that limits greenhouse-gas emissions from existing power plants. (Justin Lane/EPA) President Trump will take the most significant step yet in obliterating his predecessor’s environmental record Tuesday, instructing federal regulators to rewrite key rules curbing U.S. carbon emissions.

Trump Said to Issue Far-Reaching Reversal of Obama Climate Push - Bloomberg. President Donald Trump is set to sign a sweeping executive order on Tuesday aimed at promoting domestic oil, coal and natural gas by reversing much of his predecessor’s efforts to address climate change. The document lays out a broad blueprint for the Trump administration to dismantle the architecture that former President Barack Obama built to combat the phenomenon, according to details shared with Bloomberg News.

Oil company records from 1960s reveal patents to reduce CO2 emissions in cars.
