Analysis

Bronwyn Hayward, Jim Salinger, James Renwick and other experts respond to a critical report from the International Panel on Climate Change 

The IPCC’s latest special report, Global Warming of 1.5C, has been released at a press conference in Incheon, South Korea. Its publication follows a week-long session in Incheon. It highlights a number of climate change impacts that could be avoided by limiting warming to 1.5C above pre-industrial levels, including offering some protection to coral reefs and preventing about 10 centimetres of sea-level rise.

The NZ Science Media Centre collected comment from a range of experts.

In my view, this hard-hitting 1.5 degrees Global Warming Report marks…

A new study from researchers in California has reached some astonishing new conclusions. An interdisciplinary team composed of members from physics, physiology, statistics, and atmospheric sciences began with results from a metastudy of sperm concentration in men. This study (chart on left) confirmed that sperm concentrations have been declining since the early 70s. At the same time, measurements from the Mauna Loa Observatory show that CO2 concentrations in the atmosphere have been rising during the same period (chart on right):

After validating a parameterless model based on surprisingly common consumer software packages, the team derived a transformation equation based on τ = 1 at 1973 for the Mauna Loa data:

y =  π +κx, where π = -238 and κ = -ln(11)

The math behind all this is too advanced for most laymen to understand, but it can be illustrated in chart form quite…

Last month, deep in a 500-page environmental impact statement, the Trump administration made a startling assumption: On its current course, the planet will warm a disastrous seven degrees by the end of this century.

A rise of seven degrees Fahrenheit, or about four degrees Celsius, compared with preindustrial levels would be catastrophic, according to scientists. Many coral reefs would dissolve in increasingly acidic oceans. Parts of Manhattan and Miami would be underwater without costly coastal defenses. Extreme heat waves would routinely smother large parts of the globe.

But the administration did not offer this…

THE UNITED States have taken tensions with China to a new high by “asserting their right” to sail warships past disputed islands in the South China Sea.

By CHARLIE MOLONEY

China warn US Navy for flying past South China Sea islands

A guided-missile destroyer, USS Decatur sailed within 12 nautical miles (13.8 miles on land) of reefs near the Spratly Islands in the South China Sea, two US officials claim.

China has asserted ownership of the Spratly islands, something which was hotly contested by the US officials as “excessive maritime claims”.

Speaking to CNN, one of the officials said: “US Forces operate in the Indo-Pacific region on a daily basis, including the South China Sea. All operations are designed in accordance with international law and demonstrate that the United States will fly, sail and operate wherever international law allows.

The official said these operations “challenge excessive maritime claims and…
