Climate Change: Heatwaves and Poverty in Pakistan

by Jalees Rehman in The Next Regeneration

In the summer of 2010, over 20 million people were affected by the summer floods in Pakistan. Millions lost access to shelter and clean water, and became dependent on aid in the form of food, drinking water, tents, clothes and medical supplies in order to survive this humanitarian disaster. It is estimated that at least $1.5 billion to $2 billion were provided as aid by governments, NGOs, charity organizations and private individuals from all around the world, and helped contain the devastating ........

Estimates of Anthropogenic Nitrogen in the Ocean May Be High

by Wiley Asia Blog in Wiley Asia Blog - Life Sciences

Inundation of nitrogen into the atmosphere and terrestrial environments, through fossil fuel combustion and extensive fertilization, has risen tenfold since preindustrial times according to research published in Global Biogeochemical Cycles. Excess nitrogen can infiltrate water tables and can trigger extensive algal blooms that deplete aquatic environments of oxygen, among other damaging effects.

Although scientists have extensively studied the effects of excess nitrogen in terrestrial habita........ Read more »

Finding the real cost of climate change

by Gabriel in Lunatic Laboratories

How much does global warming really cost the world? Determining the Social Cost of Carbon helps put a actual dollar value on the climate damages per ton of CO2 released, and is used by -- among others -- policymakers to help determine the costs and benefits of climate policies. Remember, even on a global scale, the bottom line will always be profit. But now a group of economists and lawyers urge several improvements to the government's Social Cost of Carbon figure that would impose a regular, tr........ Read more »

Our Increased carbon dioxide output causes global warming and now we have proof

by Gabriel in Lunatic Laboratories

Global warming, it’s a bigger deal than some people seem to realize. For years science has pointed to the increased carbon dioxide output as the main reason for man-made global warming. However, there has been no evidence to directly link CO2 output to global warming, well until now. Research has identified, for the first time, how global warming is related to the amount of carbon emitted.... Read more »

Even more bad global warming news

by Gabriel in Lunatic Laboratories

While everyone (but seemingly the media) is on basically the same page with the fact that global warming is a human caused problem — and one we need to fix the effects of this change are still coming to light. Human-induced changes to Earth’s carbon cycle – for example, rising atmospheric carbon dioxide and ocean acidification – have been observed for decades. However, a new study showed human activities, in particular industrial and agricultural processes, have also had significant impa........ Read more »

Global Warming Denial: What Does it Take? A Case Study of Climate Change Denialists

by Nick in How to Paint Your Panda

Despite the established scientific consensus on global climate change, a substantial number of people, specifically Americans, deny its effects or its taking place. Why does this form of denialism persist so feverishly? What can mitigate this gap between the scientific community and the public?... Read more »

A Four Billion Mile Road Trip to Grandma’s

by Mark Lasbury in The 'Scope

Mankind is about to take a huge step in understanding himself and his universe. The Rosetta orbiter has traveled 3.8 billion miles to catch comet 67P/C-G. Traveling at more than 24,000 miles per hour, the Philae Lander is now going to land on the comet. A visitor from deep space and from deep time, 67P/C-G contains clues about the solar system, water, and perhaps life itself.... Read more »

A new way to look at Global Warming

by Gabriel in Lunatic Laboratories

Global warming, nothing new with that and it’s here to stay for now. But while computer models churn out bleak forecasts for the planet’s future, we also have a more conceptual understanding of what is happening as humans pump carbon dioxide into the air. Unfortunately the traditional conceptual understanding of carbon dioxide wrapping the planet in a sort of blanket that traps more heat is not quite right.... Read more »

Subduction is not the end

Subduction is just the beginning. Stuck on the surface of the earth as we are, it’s easy to think that when oceanic lithosphere is destroyed when it vanishes into the mantle. But this is wrong. The more we manage to peer … Continue reading →... Read more »

Settling velocity and grain shape of maerl

by Siddhi Joshi in Seabed Habitats

Our recent study on maerl sediment dynamics has found that the settling velocity of maerl is primarily governed by the grain shape properties of maerl. A grain shape parameter known as the convexity has been linked to the settling velocity via the Ferguson and Church model (Ferguson and Church, 2004). Due to the grain shape of maerl and roughness, it experiences a greater drag than the natural quartz grain. Detailed measurements of maërl grain shape using microscopic image analysis confirm ........ Read more »

The Oceans Link to Climate Change

by Gabriel in Lunatic Laboratories

Hold on to your hats folks, we can all agree that most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new study a group of researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate. Keep in mind this doesn’t mean global warming isn’t a man-made problem, please.... Read more »

A Venusian Mystery Explored Once More

by Gabriel in Lunatic Laboratories

Venus, the place where women are from... supposedly. To say Venus has a harsh climate would be an understatement, this is one of many reasons why we will never (or maybe not soon) see a "long lasting" Venus rover counterpart to our Mars rover missions. Still, the planet (much like all the other plants) can teach us a lot about not just our own origins, but the origins of the universe. Also like all our neighbor planets Venus is hiding something beneath its brilliant shroud of clouds, a mystery t........ Read more »

Solar Panel Hybrid is Cheap and Super Efficient

by Gabriel in Lunatic Laboratories

Solar cells are inefficient, it’s a sad fact. With todays technology they boast about a 10-15% efficiency, compare that to todays gas engine at roughly 20-25% and you can see it’s not quite up to par. Well that could all change very soon thanks to a new method for transferring energy from organic to inorganic semiconductors. This could boost the efficiency of widely used inorganic solar cells to as close as 100% efficiency as they can get.... Read more »

Orange Corn Aims to Fight Vitamin A Deficiency

by Gabriel in Lunatic Laboratories

GMO food is still a hot button topic, honestly for no other reason than fear. Sure Monsanto is a big evil corporation, but the science is only as bad as what you do with it. In the modern fortified world we don’t think about vitamin deficiency or the horrible things that come with it, however vitamin A deficiency is a huge problem in developing countries. To combat this researchers have identified a set of genes that can be used to naturally boost the provitamin A content of corn kernels, a fi........ Read more »

Chase The Good, Evade The Bad

by Mark Lasbury in As Many Exceptions As Rules

New research has found a bacterium that is spherical, yet has flagella all over its surface (peritrichous). This bacterium is also the only magnetotactic organism discovered that has both magnetite and Greigite crystals. Other research is showing that changing fields can turn magnetotactic bacteria on command. With some bacteria able to generate electrical circuits and others being able to open and close circuits on command, can bacterial computers be far away?... Read more »

Live Fast, Die Young: Evolutionary Outcomes of an Asteroid Impact

by Melissa Chernick in Science Storiented

A new semester has started and with it an influx of new students into the lab has begun. Busy has become my middle name. So when I was looking around for a paper to write about I wanted something different and cool. Not exactly hard to find in science. The asteroid known as 2012 DA14 will narrowly miss Earth this Friday, the closest known asteroid flyby on record. And by close we’re talking within the orbits of many communications satellites. This got me thinking about and looking for recent p........ Read more »

A new paradigm for Barrovian metamorphism?
