Cambridge University professor says we need to stop obsessing about net-zero

Young people are terrified that climate change will destroy Earth by the time they grow up, but the world is not actually ending, argues Cambridge professor Mike Hulme.

Humanity is not teetering on a cliff's edge, he says, at risk of imminent catastrophe if we don't reach net-zero carbon emissions by a certain date. And he has made it his mission to call out the people who claim we are.

In his most recent book, Climate Change Isn't Everything, Hulme argued that belief in the urgent fight against climate change has shot far past the territory of science and become an ideology.

Hulme, a professor of human geography at the University of Cambridge, dubs this ideology 'climatism,' and he argues that it can distort the way society approaches the world's ills, placing too much focus on slowing Earth from warming.

Scientists claim they've had a 20 minute conversation with a WHALE - and say it could pave the way for conversations with aliens someday

It might sound like something from Avatar 2 (pictured), but scientists say that this research could pave the way for future communications with aliens
It might sound like a scene out of Avatar 2.

But scientists claim it's now possible to have a conversation with a whale, following a 20-minute chat with a humpback whale in Southeast Alaska.

A 38-year-old whale named Twain 'spoke' with the researchers from the SETI Institute and UC Davis by responding to a pre-recorded 'contact call'.

This marks the first communication between humans and whales in their own language, according to the team.

Looking ahead, the researchers say the conversation could pave the way for interactions with aliens in the future.

Comment: Probably the most interesting thing about this story (aside from just how intelligent whales are) is that there are some scientists (like those at SETI) who still continue this kind of work on the pretense that humans have not yet been communicating with 'aliens,' however secretly, for a good many decades already. But a paycheck is a paycheck, and studying whale behavior sounds like a lot of fun!

Orangutan observed treating its own wound with medicinal plant for the first time

Researchers saw a male orangutan named Rakus with a face wound on June 22, 2022. Two days later, he chewed up leaves and spread the paste onto the wound
Scientists have observed a wild orangutan applying medicine to his own wound in a world's first.

A Sumatran orangutan, named Rakus, was seen chewing up leaves of a medicinal plant, create a pulp and administering the substance on an injury near his eye.

Not only were scientists amazed that the orangutan knew the plant had medicinal powers, but the sight of an ape treating its wounds have never before seen.

After two months, the wound had healed and orangutan's face showed little sign that he had ever been injured.

The surprising observation was made in Gunung Leuser National Park in South Aceh, Indonesia the summer before last.

Comment: Whilst discoveries like this are wonderful, perhaps part of our surprise stems from the fact that some of the foundations of mainstream science are still rather restrictive, despite the myriad of other awesome discoveries in recent years: And check out SOTT radio's:

New findings point to an Earth-like environment on ancient Mars

© NASA/JPL-Caltech/MSSSNASA's Curiosity rover continues to search for signs that Mars' Gale Crater conditions could support microbial life.
A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake. The results were published today in Journal of Geophysical Research: Planets.

"It is difficult for manganese oxide to form on the surface of Mars, so we didn't expect to find it in such high concentrations in a shoreline deposit," said Patrick Gasda, of Los Alamos National Laboratory's Space Science and Applications group and lead author on the study.

"On Earth, these types of deposits happen all the time because of the high oxygen in our atmosphere produced by photosynthetic life, and from microbes that help catalyze those manganese oxidation reactions.

"On Mars, we don't have evidence for life, and the mechanism to produce oxygen in Mars's ancient atmosphere is unclear, so how the manganese oxide was formed and concentrated here is really puzzling. These findings point to larger processes occurring in the Martian atmosphere or surface water and shows that more work needs to be done to understand oxidation on Mars," Gasda added.

Earth receives NASA space laser transmission from 140 million miles away

Psyche spacecraft laser transmission record distance

This redefined a long-distance call.

Earth just received a laser transmission from a world- (and perhaps universe) record-breaking 140 million miles away — which could have major implications for the future of space travel.

However, this correspondence wasn't extraterrestrial in origin: It was actually sent by NASA's Psyche spacecraft, which is currently located approximately 1.5 times the distance between Earth and the Sun.

"This represents a significant milestone for the project by showing how optical communications can interface with a spacecraft's radio frequency comms system," Meera Srinivasan, the project's operations lead at NASA's Jet Propulsion Laboratory in Southern California, said in a statement.

New evidence found for Planet 9

Both panels depict the perihelion distance against the semi-major axis of orbital footprints of simulated TNOs with i < 40 deg. The overlaying contour lines represent density distributions, with brighter colors indicating higher concentrations of objects. While the panels themselves show raw simulation data, the histograms along the axes show a biased frequency distribution for the perihelion distances (vertical) and semi-major axes (horizontal), assuming a limiting magnitude of Vlim = 24.
A small team of planetary scientists from the California Institute of Technology, Université Côte d'Azur and Southwest Research Institute reports possible new evidence of Planet 9. They have published their paper on the arXiv preprint server, and it has been accepted for publication in The Astrophysical Journal Letters.

In 2015, a pair of astronomers at Caltech found several objects bunched together beyond Neptune's orbit, near the edge of the solar system. The bunching, they theorized, was due to the pull of gravity from an unknown planet — one that later came to be called Planet 9.

Since that time, researchers have found more evidence of the planet, all of it circumstantial. In this new paper, the research team reports what they describe as additional evidence supporting the existence of the planet.

The work involved tracking the movements of long-period objects that cross Neptune's orbit and exhibit irregular movements during their journey. They used these observations to create multiple computer simulations, each depicting different scenarios.

Rare quadruple 'super-sympathetic' solar flare event captured by NASA

Earlier this week, NASA's Solar Dynamics Observatory (SDO) recorded a rarely seen event — four nearly-simultaneous flare eruptions involving three separate sunspots, as well as the magnetic filament between them. But as impressive as it is, the event could soon pose problems for some satellites and spacecraft orbiting Earth, as well as electronic systems here on the ground.


Comment: More so considering how, with Earth's weakening magnetic field, even relatively moderate solar flares have been shown to disrupt groundbased instruments: (2023) Powerful Solar storm has unusually strong impact on Earth, delays SpaceX rocket launch, stalls oil rigs in Canada


It may seem like a massive ball of fiery, thermonuclear chaos, but there's actually a fairly predictable rhythm to the sun.
Similar to Earth's seasonal changes, the yellow dwarf star's powerful electromagnetic fluctuations follow a roughly 11-year cycle of ebbs and flows.


Although astronomers still aren't quite sure why this happens, it's certainly observable — and recent activity definitely indicates the sun is heading towards its next "solar maximum" later this year.

New scientific evidence that CO2 emissions can't warm atmosphere because it is "saturated" published in peer-reviewed journal

Further scientific evidence has emerged to suggest that the Earth's atmosphere is 'saturated' with carbon dioxide, meaning that at higher levels the 'greenhouse' gas will not cause temperatures to rise. A group of Polish scientists led by Dr. Jan Kubicki have published three papers recently, and according to the science site No Tricks Zone they summarise their evidence by noting: "
As a result of saturation, emitted CO2 does not directly cause an increase in global temperature". Current levels of CO2 in the atmosphere are around 418 parts per million (ppm) but the scientists state that past 400 ppm, "the CO2 concentration can no longer cause any increase in temperature."
As regular readers of the Daily Sceptic will be aware, the saturation of CO2 in the atmosphere is the hypothesis that dares not speak its name in mainstream media, politics and across much of climate science. The Net Zero collectivisation project is dead in the water without the constant fearmongering that humans control the ever-warming climate by burning hydrocarbons and releasing CO2 into the atmosphere.

The saturation hypothesis is complex, but in simple terms it can be described by the example of loft insulation in a house. After a certain point, doubling the lagging will have little effect since most of the heat trying to escape through the roof has already been trapped. Carbon dioxide traps heat only within narrow bands of the infrared spectrum, and levels of the gas have been up to 20 times higher in the past without any sign of runaway global warming. At current levels, the Polish scientists suggest that there is "currently a multiple exceedance of the saturation mass for carbon dioxide in the Earth's atmosphere". The latest work is featured on Elsevier's Science Direct peer-reviewed online platform.

Many animals can glow in the dark. Fireflies famously blink on summer evenings. But most animals that light up are found in the depths of the ocean.

In a new study, scientists report that deep-sea corals that lived 540 million years ago may have been the first animals to glow, far earlier than previously thought.

"Light signaling is one of the earliest forms of communication that we know of — it's very important in deep waters," said Andrea Quattrini, a co-author of the study published Tuesday in the journal Proceedings of the Royal Society B.

Comment: Despite appearances, corals are animals, and fascinating ones at that.

The pioneering Voyager 1 deep-space probe is once again sending usable engineering updates back to Earth after five months of repairs, NASA officials announced Monday.

Voyager 1, which along with its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space, has not been able to send readable data about its health or scientific mission since Nov. 14.

But following lengthy and sophisticated attempts to establish a technological work-around, NASA revealed Monday its engineers had succeeded in once again receiving Voyager's engineering status updates that can be deciphered.
