As supporting evidence, he said , there was a two-day gap in the data, something backed up by Icelandic astronomer Steinn Sigurdsson, who provided this link to its schedule. The device refused one of the gyros. NASA's decision to retire its space shuttles in 2011 means that astronauts can not service the 28-year-old observatory as they once did. (more...)

Such spikes occur in extremely cold and dry conditions, when under the influence of sunlight the ice undergo sublimation - they move from solid to gas, bypassing the liquid stage, according to the study . The blades of sharp ice on Jupiter's moon Europa are called "penitentes". Conditions on Europa may be ideal for "penitentes" to form, which are spiky, bladed ice formations found on Earth at higher elevations such as the Andes Mountains. (more...)

But the take-home for Donner from this report is the consequences for other parts of the world if warming exceeds 1.5 C. If 1.5 degrees of warming does occur, Southeast Asian countries like Indonesia, the Philippines, and Vietnam, including countries like Japan, China, Egypt, and the US will experience increased flooding by 2040.

Australia refuses to abandon coal despite IPCC warning Australia refuses to abandon coal despite IPCC warning
- October 10, 2018

To contain warming at 1.5°C, man-made global net Carbon dioxide emissions needs to fall by about 45 percent by 2030 from 2010 levels and reach "net zero" by mid-century. The climate change is real and it is illustrated by the heat wave conditions spreading like a plague in India and Pakistan. In these climate change "hotspots" - prone to droughts and floods - local warming and drying will be greater than the global average. (more...)

On the exposed coast of Florida's Big Bend, most of the waterfront homes in Keaton Beach stood vacant amid fears of a life-threatening storm surge in an area that hadn't seen a potentially catastrophic major hurricane in decades. Five drilling rigs have been moved out of the storm's path, according to the US Bureau of Safety and Environmental Enforcement. Northwest Florida as a region attracted almost 17 million visitors in 2016, or 15 percent of total tourists in the state, according to ... (more...)

But now, Branson says, "We should be in space within weeks, not months. And then we will be in space with myself in months and not years", after which point his piggybacking little spaceships will open their hatches to the paying public; beating rival nouveau billionaires Musk and Bezos to the PR win of being first to offer orbital holidays to the super rich.

The report does describe how much more serious climatic impacts will be if the world lets warming reach 2 degrees Celsius above pre-industrial levels. "You know, which group drew it", Trump said on the White House's South Lawn. The planet is already experiencing the effects of global warming . Problematically, the effectiveness of the negative emissions techniques that would be relied upon in such a scenario is unproven on a large scale. (more...)

And even though it's up to the governments to reach the IPCC's emission goals, we can all be more conscious about our own waste. Climate change is a global challenge demanding global solutions. Global Warming of 1.5 °C is the first in a series of Special Reports to be produced in the IPCC's Sixth Assessment Cycle. Collapse of coral reefs would be essentially ensured. (more...)

The IPCC warns, however, there is a stark difference between 1.5 and even 2 degrees Celsius of warming. Emissions of other greenhouse gases, such as methane, also will have to drop. The IPCC report is undeniably grim, but its authors state that the 1.5°C target can still be met if unprecedented, wide-ranging action is taken straight away. (more...)
US Gulf Coast bracing for 'monstrous' Hurricane Michael US Gulf Coast bracing for 'monstrous' Hurricane Michael

Senate. Catastrophe risk modelling firm RMS has highlighted some key differences between hurricane Michael, which is heading for the Florida coast and expected to be a major category storm at landfall, with recent hurricane Florence. Interests along the northeastern and central Gulf Coast areas are advised to monitor the progress of Tropical Storm Michael. Hurricane Michael suddenly became news on Monday after eclipsing its former tropical-storm status while lashing Cuba . (more...)

When Voyager 1 saw a similar increase in cosmic rays, it was about three months later when the spacecraft entered interstellar space. This is the same thing that happened to Voyager 1 when it finally broke out of our system's heliosphere, which is the "vast bubble around the sun and planets dominated by solar material and magnetic fields", according to NASA .

EDT (7:21 p.m. local time; 0221 GMT on October 8), successfully delivering Argentina's SAOCOM-1A Earth-observation satellite to orbit. Despite repeated warnings during the week in the build-up to the launch, it appears many residents in California didn't get the memo. (more...)
Dire warnings and urgent calls in climate change report

While government representatives are frankly buried by more high-quality scientific information than they really need to make sound decisions about the urgency of slowing climate change , they ordered up a 1.5°C addendum. Similarly, when it comes to heat waves, in a world that's warmed by up 1.5C, about 14% of the population are exposed to a heat wave every five years. (more...)

A tropical storm off Mexico's Yucatan Peninsula has rapidly strengthened and could become a unsafe hurricane before an expected midweek strike on the Gulf Coast in the Florida Panhandle, forecasters said Monday. The storm was about 145 miles (230 km) northeast of Cozumel, Mexico, with maximum sustained winds of 75 mph (120 kph), forecasters said. Predictions from the National Weather Service say the area can expect 2 to 4 inches of rain and it has a good chance of seeing tropical ... (more...)

This degree of coverage, according to the researchers, would lead to a 0.24 degree Celsius increase in temperature. David Keith and Lee Miller from Harvard made a decision to help us improve our knowledge on the subject by simulating how the United States would look if all the energy would come from wind power.

Hubble in trouble: space telescope out of action as gyroscope fails
- October 08, 2018

The deputy mission head for the Hubble Space Telescope (HST), Dr Rachel Osten, confirmed a rumour on Twitter that it was now in safe mode - potentially for weeks - following a gyro failure. The gyroscopes have a habit of burning out, hence their replacement many years back, but this most recent failure means that the telescope only has two functioning gyroscopes remaining. (more...)

The loudness of the boom will depend on the weather and other conditions, officials added. The company said on social media it had been successful. The primary objective of the mission was to place the SAOCOM 1A satellite into orbit, but SpaceX also wanted to expand its recovery of first stages to its launch site at Vandenberg Air Force Base, about 130 miles northwest of Los Angeles.

You can start looking for the Draconids in the sky from 21:00, but the chances to see the attractive show increase after midnight. Still, it's worth looking up, as the shower sometimes puts on an incredible display. As Earth passes through the comet's tail, the debris from the meteor burns up - causing shooting stars. Because of their Jekyll and Hyde personality, the Draconid meteors can be some of the most surprising ones out there. (more...)

Professor Mona Sirbescu was asked to examine different types of ordinary rocks throughout her career. According to Professor Sirbescu, it has been 18 years of "no" and finally when she saw the MI man brought the rock to the university, she knew this was it! Experts said the almost 23-pound hunk of iron and nickel is the sixth largest meteorite found in MI. (more...)

Upon purchasing it, he noticed a large rock holding the door open, according to Central Michigan University. " It's the most valuable specimen I have ever held in my life, monetarily and scientifically ", she added. This is the rags-to-riches story of a rock from outer space. The then owner told the man it was part of the property, and he could keep it. The rock landed on Earth sometime in the 1930s, according its proprietor, who procured it in 1988 when he purchased a farm in Edmore, ... (more...)

Some cosmic rays get blocked by the heliosphere. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Beginning last August, Voyager 2's Cosmic Ray Subsystem (CRS), built to detect cosmic rays, noticed a five percent increase in these rays hitting the probe. (more...)
