Climatologists found that the carbon dioxide levels have risen so high that they could have catastrophic consequences to our life on the planet earth. Prior to the 18th century the levels were averaging about 280 ppm (parts per million). The Industrial Revolution began burning fossil fuels which sent more carbon dioxide into the atmosphere. They are predicting that our carbon […]

Until recently, Pakistan has not used the bulk of its coal reserves – some of the largest in the world – for power generation. Within the past year the government in Islamabad has signed a number of financial and technological agreements with China aimed at exploiting massive coal reserves at the Tharparkar mine in Sindh province, in the south of the […]

Researchers from Australia, Denmark, Germany, Norway, United Kingdom, and the United States conducted lead concentration measurements of sixteen ice core samples, and found that industrial air pollution has persisted Antarctica since its arrival there in 1889 and remains significant in the current century. Their study was published in Scientific Reports on July 28, and covered in Nevada‘s Review journal. Lead […]

One of the most common arguments of those skeptical of global warming is that the Medieval Warm Period (800-1400 AD) was as warm as or warmer than today. Using this as proof to say that we cannot be the cause of current global warming is a faulty notion based upon rhetoric rather than science. So what are the holes in […]

People always wonder how the moon was made. The birth of the planets 4.5 billion years ago was extremely violent. They grew to full size by absorbing rival planet embryos in a series of titanic collisions—one of which probably gave Earth its moon (below). The moon’s large size, low density, and other features suggest that it emerged from an explosion […]

Vast reserves of freshwater have been discovered beneath the seabed of continental shelves off Australia, China, North America, and South Africa—a potentially valuable resource for coastal cities needing to alleviate water shortages or combat drought. The finding comes from a new analysis of seafloor water studies conducted for oil and gas exploration purposes. The total volume of these untapped reserves […]

Earth got off relatively easy last week after being hit by the biggest blast of solar radiation since 2005—but we may not be so lucky next time. Last week’s coronal mass ejection, in which a solar flare whipped an arc of magnetic particles toward Earth at 4 million mph, led some airlines to reroute flights away from the poles, where […]

More than 850 million people around the world—one in nearly seven—don’t have enough to eat. Although current global food production is sufficient to feed everyone, the number eating less than the minimum the human body needs—an average 2,100 calories a day for adults—now grows by more than ten million a year, mostly in the poorest nations. Countries with unstable food […]

“It has happened,” said Philip Bump. For the first time in human history, atmospheric carbon dioxide levels hit a daily average of 400 parts per million (ppm) last week. “There is now more carbon dioxide in the atmosphere than at any point since 3 million years ago.” Back then, global temperatures were about 7 degrees higher, the Arctic was ice-free, […]

It’s been five years since the Deepwater Horizon oil rig exploded in the Gulf of Mexico, killing 11 and releasing a torrent of petroleum into the sea. But despite a massive, multibillion-dollar cleanup effort, the effects of the largest marine oil spill in U.S. history may linger for decades. BP (British Petroleum), which operated the rig, has already paid […]
