            "description": "Many places call themselves the hottest on Earth, but most are not serious contenders. Ground-based weather stations typically sit near civilized areas and don't reveal the full story. Satellites, however, observe the entire planet, including extreme environments where no human wants to be. By detecting land skin temperatures—which often significantly exceed air temperatures and provide a measure of how the land absorbs and re-emits solar energy—satellites can dispel myth. Scientists analyzing NASA satellite data found the hottest spot on Earth changed three times within seven years, but the characteristics of each location were the same—dry, rocky, dark-colored and remote, like the land surrounding China's Flaming Mountain, pictured above. Temperatures in these places often top out above 150 degrees Fahrenheit (65 || ",

            "title": "Carbon Catch And Release",
            "description": "Through tiny, microscopic pores called stomata, plants absorb one hundred billion tons of carbon from the air each year and convert about half of that into organic matter—leaves, roots, tree branches, grass. As we continue to increase the level of carbon dioxide in the atmosphere, knowing exactly how much carbon Earth's plants absorb from the air—Gross Primary Productivity (GPP)—will become only more important. NASA has closely measured this since 2000, and that volume of absorption is seen in the first visualization below as waves of green. The northern hemisphere all the way up to the Arctic Circle swells with life each summer, before much of the vegetation wilts and exhales its carbon in fall and winter. Meanwhile, forests such as the Amazon, a robust green throughout, show off their amazing productivity despite seasonal changes. || ",

            "title": "How Much Carbon do Plants Take from the Atmosphere?",
            "description": "Plant life converts atmospheric carbon dioxide into biomass through photosynthesis, a process called 'fixing'. This is one of the main ways in which carbon dioxide is removed from the atmosphere and is a major part of the carbon cycle. The amount of carbon removed is called the gross primary productivity (GPP), and the change in GPP due to rising global temperatures is very important factor in the response of the Earth to climate change.Data from the MODIS instrument on NASA's Terra satellite has been recently used to calculate the GPP for the whole world for the last 10 years. This animation shows a time sequence of GPP on land as measured by MODIS during the years 2000 through 2009. Two things to note are the year-long productivity of the tropical regions and the large seasonal productivity in the northern hemisphere. A close look at the animation also reveals major urban areas for which the productivity is negligible.For a look at why the decade from 2000 through 2009 meant lower productivity, see the page 'How has the Atmospheric Carbon Uptake from Plants Changed in the Last Decade?' || ",

            "description": "Plant life converts atmospheric carbon dioxide into biomass through photosynthesis. This process, called fixing, is one of the main ways in which carbon dioxide is removed from the atmosphere and is a major part of the carbon cycle. Plants release a fraction of this fixed carbon by respiration in order to get energy to live and to move carbon to other organs. The amount of carbon removed minus the amount of carbon respired is called the net primary productivity (NPP) and is the amount of carbon turned into biomass.The change in NPP due to rising global temperatures is a very important factor in the response of the Earth to climate change. Measurements of radiation and leaf area from the MODIS instrument on NASA's Terra satellite have recently been used to calculate the change in NPP for the whole world for the last 10 years. This animation shows a time sequence of annual NPP deviation from normal (or 'anomaly') on land as measured by MODIS during the years 2000 through 2009. Annual NPP, especially its departures from a long-term mean condition, will demonstrate the effects of environmental drivers such as ENSO (El Niño) events, climate change, droughts, pollution episodes, land degradation, and agricultural expansion.Earlier studies of productivity between 1982 and 1999 showed that prouctivity went up as global temperatures rose, because longer, warmer growing seasons were better for plant growth. This new study indicates that this is still true in the northern hemisphere, but that increased temperatures have meant increased drought and dryness in the tropics and the southern hemisphere. As a result, the global net productivity has actually decreased in the period from 2000 through 2009.Regionally, negative annual NPP anomalies were mainly caused by large-scale droughts. In 2000, droughts reduced NPP in North America and China; in 2002, droughts reduced NPP in North America and Australia; in 2003, drought caused by a major heat wave reduced NPP in Europe; in 2005, severe droughts in the Amazon, Africa, and Australia greatly reduced both regional and global NPP; from 2007 through 2009 over large parts of Australia, continuous droughts reduced continental NPP.For an animation of daily productivity, see the page How Much Carbon do Plants Take from the Atmosphere?. || ",

            "title": "Plant Productivity in a Warming World",
            "description": "The past decade is the warmest on record since instrumental measurements began in the 1880s. Previous research suggested that in the '80s and '90s, warmer global temperatures and higher levels of precipitation — factors associated with climate change — were generally good for plant productivity. An updated analysis published this week in Science indicates that as temperatures have continued to rise, the benefits to plants are now overwhelmed by longer and more frequent droughts. High-resolution data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, indicate a net decrease in NPP from 2000-2009, as compared to the previous two decades. || ",
