Investors urge heavy carbon emitters to set science-based reduction targets

LONDON (Reuters) – Investors managing around $20 trillion in assets on Tuesday called on the heaviest corporate emitters of greenhouse gases to set science-based targets on the way to net zero carbon emissions by mid-century.

AXA Group and Nikko Asset Management Co are among 137 investors urging 1,800 companies responsible for a quarter of global emissions to act, coordinated by non-profit group CDP.

While more companies are pledging their support for the 2015 Paris agreement on climate change, aiming to be carbon neutral by 2050, not all have been clear about how they will get there.

To help limit global warming to no more than 1.5 degrees Celsius above pre-industrial norms by 2050, companies need to set out their pathway to net zero and ensure it is consistent with the science and independently verified, the investors said.

“Climate change presents material risks to investments, and companies that are failing to

Astronomers turn up the heavy metal to shed light on star formation

Astronomers from The University of Western Australia’s node of the International Center for Radio Astronomy Research (ICRAR) have developed a new way to study star formation in galaxies from the dawn of time to today.


“Stars can be thought of as enormous nuclear-powered processing plants,” said lead researcher Dr. Sabine Bellstedt, from ICRAR.

“They take lighter elements like hydrogen and helium, and, over billions of years, produce the heavier elements of the periodic table that we find scattered throughout the universe today. The carbon, calcium and iron in your body, the oxygen in the air you breathe, and the silicon in your computer all exist because a star created these heavier elements and left them behind,” Bellstedt said. “Stars are the ultimate element factories in the universe.”

Understanding how galaxies formed stars billions of years ago requires the

Watch ULA Launch a Spy Satellite on a Delta IV Heavy Rocket Tonight

A United Launch Alliance Delta IV Heavy rocket carrying a classified payload for the National Reconnaissance Office will take off from Cape Canaveral Space Launch Complex-37 in Florida shortly before midnight on Wednesday. Assuming, that is, there isn’t another one of the last-minute delays that have hounded the mission for months.

The rocket and its semi-mysterious payload, dubbed NROL-44, were originally slated to take off in June. But NROL-44 was delayed until Aug. 29 with no explanation ever offered to the public, according to Ars Technica. It then malfunctioned on that date, with a faulty part causing a hotfire abort after its three RS-68 engines had already begun firing. Repairs took weeks.

NROL-44 was then scheduled to take off on Sept.

Study delivers new knowledge on thunderstorms and heavy rain — ScienceDaily

Thunderstorms are weather disturbances characterized by concentrations of thunder, lightning and fierce winds.

When they accumulate in clusters, these storms are often accompanied by violent cloud bursts and flooding, which can devastate the areas affected.

Denmark is no stranger to this phenomenon. In 2011, large parts of Copenhagen were submerged by deluges that lead to roughly 6 billion kroner in damages reported to insurance companies.

In a new study, researchers from the University of Copenhagen shed light on one particular mechanism that has the potential to spawn powerful thunderstorms and cloud bursts:

“We conclude that the atmosphere’s ability to generate large thunderstorms is influenced, among other things, by the difference between the temperature of the earth’s surface during the night versus during the day. If the difference is great, we see more thunderstorms, and subsequently, more cloud bursts,” explains Jan Olaf Härter, an associate professor at the University of Copenhagen’s

You can watch a US spy satellite launch on a giant Delta IV Heavy rocket tonight. Here’s how.

CAPE CANAVERAL, Fla. — A new U.S. spy satellite will launch into space early Saturday (Sept. 27) on the mightiest rocket built by the United Launch Alliance (ULA): the massive Delta IV Heavy.

The booster is set to blast off overnight at 12:10 a.m. EDT (0410  GMT) from Pad 37 here at the Cape Canaveral Air Force Station to carry the classified NROL-44 satellite into orbit for the  the National Reconnaissance Office (NRO). You  can watch all the fiery action live online, courtesy of ULA. Launch coverage will begin about 20 minutes prior to liftoff, and you can watch the launch live here and on the Space.com homepage or directly via the ULA webcast. 

The mission has been delayed nearly a month after a rare, last-second abort on the launch pad on Aug. 29. According to ULA, the launch window lasts about 94 minutes.
