CO2, Climate Change Seen As Waste Disposal Challenge When it comes to carbon dioxide, what goes up doesn’t come down. It stays in the atmosphere for thousands of years after plumes of pollution have been released from tailpipes and power plants, trapping heat and warming the planet. That’s why some scientists are increasingly looking at global warming as a waste disposal problem. They say that thinking of emissions in terms of trash that needs to be taken out may draw more attention to something called negative carbon emissions — the process of physically removing carbon dioxide from the air to reduce its concentration in the atmosphere. Pollution from a coal-fired power plant in Germany.
Tiny sea creatures are saving us from hell on earth. So why are we endangering them? Deep in the ocean where the sun don’t shine, fissures in the earth’s crust spew super-heated geothermal water and gases of up to 400 degrees Celsius. Sounds like hell? Not quite — hydrothermal vents discovered just 40 years ago by scientists, teem with a surprising abundance of life. And these hotbeds of biodiversity are crucial for underwater ecosystems and the global climate, according to a recent report in Frontiers In Marine Science. The vents dot the sea floor at depths of 5,000 to 13,000 feet, gushing sulfides, methane, iron, and hydrogen into the ocean.
Educational Technology and Mobile Learning: The New Google Earth Has Exciting Features for Teachers April , 2017 Google has just released a brand new version of Google Earth for both Chrome and Android. This new version has come with a bunch of interesting features you can use for educational purposes with your students in class. Here is a quick overview of each of these features: 1- Voyager Voyager is a showcase of interactive guided tours to help you virtually explore beautiful places from all around the globe. *****Climate change could transform gardens (RHS 2017 report) Artificial lawns, plants from arid countries and flower beds designed to cope with floods are among future features of UK gardens outlined in a major new report. As the world warms and weather patterns shift, the study by the Royal Horticultural Society (RHS) concludes that British gardens will need to adapt. Traditional designs with "immaculate, well-watered lawns" and "Edwardian" borders may be too hard to maintain if the weather becomes more volatile. The report warns that climate change looks set to bring more extremes and more erratic weather with stronger storms, heavier downpours and more intense heatwaves potentially damaging plants and eroding soil.
So You Think You Can Scroll Jim Vallandingham @vlandham Abusing The Force So You Think You Can Scroll Scrolling 4 Reasons the Paris Agreement Won’t Solve Climate Change Many hail the Paris agreement—set to cross the threshold this week to come into effect—as a panacea for global climate change. Yet tragically, this perspective neglects to take into account the scientific reality of our climate system, which tells a much different story. Our latest research, Young People's Burden: Requirement of Negative CO2 Emissions, appeared Monday as a "Discussion" paper in Earth System Dynamics Discussion, and outlines how—if national governments neglect to take aggressive climate action today—today's young people will inherit a climate system so altered it will require prohibitively expensive—and possibly infeasible—extraction of CO2 from the atmosphere. Global temperatures are already at the level of the Eemian period (130,000 to 115,000 years ago), when sea level was 6-9 meters higher than today.
ncentrations of warming gases break record 6 November 2013Last updated at 05:07 ET By Matt McGrath Environment correspondent, BBC News The WMO says that fossil fuel activities such as oil refining are driving atmospheric levels of CO2 to record highs Child Mortality - Our World In Data Since the beginning of the age of the Enlightenment and over the course of modernization, the mortality of children below 5 years of age has declined rapidly. Child mortality in rich countries today is much lower than 1%. This is a very recent development and was only reached after a hundredfold decline in child mortality in these countries.
*****Arctic Sea Ice Volume/Thickness (animations) Under Construction Trends in sea ice thickness/volume are another important indicator of Arctic climate change. While sea ice thickness observations are sparse, here we utilize the ocean and sea ice model, PIOMAS (Zhang and Rothrock, 2003), to visualize March sea ice thickness and volume from 1979 to 2017. Top 15 Best Information Graphics and Data Viz from 2016 Are you ready for the biggest information explosion in history? If you don’t know by now, the Internet of Things (IoT) is going to take the world by storm in the coming years. A system of interconnected physical devices, IoT will enable humans, animals and man-made objects to transmit data over a network through biochip implants, built-in sensors or any other thing that can be assigned an IP address.
News - Game over? Will global warming be even worse than we think? - The Weather Network OUT OF THIS WORLD | What's Up In Climate Change - a glance at the most important news about our warming world Scott Sutherland Meteorologist/Science Writer Friday, November 18, 2016, 7:29 PM - The Arctic is running a severe fever, global sea ice is at record low levels, and could climate change get even worse than we thought as global temperatures rise? Cutting soot and methane emissions would not help the climate as much as hoped We’re not making great progress cutting carbon dioxide emissions on a global scale, so the U.S. has been working with other nations on the less controversial strategy of reducing methane and soot. These pollutants have more severe immediate impacts on the climate than does CO2, and they break down much more quickly in the atmosphere. But research published this week in Proceedings of the National Academy of Sciences suggests that this strategy would be less effective than previously believed. Scientists modeled the climatic effects of a dreamy scenario: Methane emissions are reduced to the greatest extent thought possible; the use of wood- and coal-burning stoves and heating systems is phased out worldwide by 2035; and strict controls are placed on vehicle exhaust.
The rise of humankind, in one mesmerizing map Today, human influence has transformed almost every part of the globe. But looking at the span of human history, this wasn't the case until quite recently. That's one of the many lessons from a series of fascinating maps and charts from WorldPopulationHistory.org, which shows the explosive growth of the world's human population from 1 CE (1 AD) to the present and into the future. Each of the dots in the map below indicates 1 million people, with some of the dots placed in the middle of a more spread-out population. The video demonstrates how the world population grew from only 170 million people in 1 CE to nearly 7.4 billion currently.
