The Clayola self-watering system

Waters 6 plants for up to 1 month using nothing but gravity. A system of Clayolas connected to a water tank will let each plant draw the exact amount of water it needs. 80% more efficient than traditional watering and drip irrigation methods. A system of Clayolas installed in planting pots and connected to a water tank will let each plant draw the amount of water it needs until the tank is empty. You can recycle an old jar. An empty 20 liter water cooler container would be perfect. Via Clayola

Amazonia a world resource at risk

The Amazon basin houses a gigantic ecological machine of global importance being cannibalised for its parts. The human exploitation of Amazonia bears upon the food we eat, the medicine we take, the wood we use, and the temperature outside our doors. The basin sprawls over parts of seven countries and embraces a variety of terrains dominated by the world’s largest tropical rain forest. Solar radiation and water drive this ecosystem in an endless cycle: Ocean evaporation falls as rain, which returns to the sea or rises, by transpiration from vegetation, back to the atmosphere. On a larger scale, hot tropical air rises along the equatorial belt and spreads toward the Poles, as cold polar air sinks and moves toward the Equator. The earth’s rotation deflects this north-south movement, creating trade winds that meet in the intertropical convergence zone. The northeast trade winds transport dust from deserts in Africa, enriching thin rain forest soil an ocean away. Healthy, the forest is

Highlights of Global Climate 2016

The warmest year on record: +0.83 °C +/− 0.10 °C warmer than the average for the 1961–1990 reference period, +1.1 above the pre-industrial period. The 2015/2016 El Niño is one of the three strongest events since 1950. Sea Level On timescales longer than about a year, the vast majority (more than 90%) of the Earth’s energy imbalance goes into heating the oceans. As the oceans warm, they expand, resulting in both global and regional sea-level rise. Globally, sea level has risen by 20 cm since the start of the 20th century, due mostly to thermal expansion of the oceans and melting of glaciers and ice caps. Some regions are experiencing greater sea-level rise than others. The tropical western Pacific observed some of the highest rising sea-level rates over the period 1993–2015, which was a significant factor in the enormous devastation in parts of the Philippines when Typhoon Haiyan caused a massive storm surge in November 2013. EL Niño 2015/2017 The year began with a strong El Ni

Arctic sea ice maximum at record low for third straight year

On March 7, 2017, Arctic sea ice likely reached its maximum extent for the year, at 14.42 million square kilometers (5.57 million mi2), the lowest in the 38-year satellite record. This year’s maximum extent is 1.22 million square kilometers (471,000 mi2) below 1981 to 2010 average maximum of 15.64 million square kilometers (6.04 million mi2) and 97,000 square kilometers (37,000 mi2) below the previous lowest maximum that occurred on February 25, 2015. This year’s maximum is 100,000 square kilometers (39,000 mi2) below the 2016 maximum, which is now third lowest. Via nsidc.org In Antarctica, this year’s record low annual sea ice minimum of 815,000 square miles (2.11 million square kilometers) was 71,000 square miles (184,000 square kilometers) below the previous lowest minimum extent in the satellite record, which occurred in 1997.

Thermal Electricity by Country

A thermal power station is a power plant in which heat energy is converted to electric power. In most of the places in the world, the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different heat sources, fossil fuel dominates here, although nuclear heat energy and solar heat energy are also used.Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy.Certain thermal power plants also are designed to produce heat energy for industrial purposes of district heating, or desalination of water, in addition to generating electrical power. Almost all coal, nuclear, geothermal, solar thermal electric, and waste incineration plants,

Topographic map of Greenland without its ice sheet

The Greenland ice sheet is the second largest ice body globally, after the Antarctic ice sheet, embracing 1.71 million square kilometers (660 thousand sq mi), approximately 79 percent of the cover of Greenland for the last 18 million years.  The mean elevation of the ice is 2.1 kilometers or 1,3 miles (over 3 km or 1.9 mi at its thickest point). Nowadays, Greenland is losing approximately 260 billion tonnes of ice to the ocean each year. If the whole 2.85 million cubic kilometers (684 thousand cubic mi) of ice were to melt, it would increase the global sea level by 7.42 meters (24.34 feet). The map below shows a topographic map of Greenland without its ice sheet.

People Cause Most US Wildfires

University of Colorado scientist Jennifer Balch and several colleagues came to their conclusion after analyzing reports of 1.6 million wildfires from a comprehensive’s fire occurrence database maintained by the U.S. Forest Service. As shown by the map above, almost all (84 percent) of the fires in the Mediterranean ecosystems of central and southern California, the temperate forests of the eastern United States, and the temperate rainforests of the Pacific Northwest are caused by humans. The researchers also found that human-ignited fires tripled the length of the wildfire season. Though lightning-ignited fires were clustered in the summer, human-ignited fires occurred in the spring, fall, and winter as well, times when forests tend to be moist. During these seasons, people added more than 840,000 fires - a 35-fold increase over the number of lightning-started fires.

Daily spring index leaf anomaly (2017)

"Spring is arriving very early this year . . . at least 2-3 weeks early across almost the entire Southeast, from San Antonio to Atlanta to Washington, D.C." "When the researchers applied the plant models to the recent weather data, they were able to create national-scale daily maps of leaf emergence for these plant species. Then, by comparing the daily maps from this year to historical maps created the same way, they created maps that showed just how different this year is relative to the long-term average (1981-2010). It is these data that reveal just how unusually early spring is arriving across most of the USA this year." "The Spring Leaf Index is a measure of these early season events in plants, based on recent temperature conditions. This model allows us to track the progression of spring onset across the country. The map shows locations that have reached the requirements for the Spring Leaf Index model." Via usgs.gov

Asian pollution, heat waves worsen U.S. smog

Surface-level ozone, also known as smog, has increased over the past quarter century at western US rural sites during springtime, partly due to rising Asian pollution, whereas smog has decreased in the eastern US but can spike due to heat waves, according to a new study from Princeton University and the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory (GFDL). Shown are the 1988-2014trends in springtime ozone levels on days that were very smoggy (top panel) and of average smogginess (bottom panel), from observations (left) and from a model built by the Geophysical Fluid Dynamics Laboratory (right). Larger circles indicate sites where there is greater certainty about the ozone trend. On very smoggy days (top panel), ozone levels have declined in the east, as indicated by the blue circles. Ozone levels have increased in the west, as indicated by the red circles, despite a 50 percent reduction in the emission of smog-forming pollutants. Credit:
