Climate Change And Global Warming - think

Greenhouse gases from human activities are the most significant driver of observed climate change since the mid th century. As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes. These changes have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations. Some of the excess carbon dioxide is absorbed quickly for example, by the ocean surface , but some will remain in the atmosphere for thousands of years, due in part to the very slow process by which carbon is transferred to ocean sediments. Greenhouse Gas Emissions indicator come from the national inventory. This report tracks trends in total annual U. EPA uses national energy data, data on national agricultural activities, and other national statistics to provide a comprehensive accounting of total greenhouse gas emissions for all man-made sources in the United States.

Temperatures were warmer than average across most global land and ocean areas during most of the year. The final frame of animation shows where annual temperatures were warmer red or colder blue than average. NOAA Climate. Record high sea surface temperatures were observed across parts of all oceans, including the North and South Atlantic Ocean, the western Indian Ocean, and areas of northern, central and southwestern Pacific Ocean. No land or ocean areas were record cold for the year, and the only substantial pocket of cooler-than-average land temperatures was in central North America. Though warming has not been uniform across the planet, the upward trend in the globally averaged temperature shows that more areas are warming than cooling.

Changes in global average surface temperature from The Climate Change And Global Warming warmest years on record have all occurred sinceand 9 of the 10 have occurred since The year is the only year from the twentieth century still among the ten warmest years on record.

Bymodels project that global surface temperature will be more than click. This similarity in temperatures regardless Changs total emissions is a short-term phenomenon: it reflects the tremendous inertia of Earth's vast oceans. The high heat capacity of water means that ocean temperature doesn't react instantly to the increased heat being trapped by greenhouse gases.

The concept of an average temperature for the entire globe Climate Change And Global Warming seem odd. Temperatures vary from night to day and between seasonal extremes in the Northern and Southern Hemispheres. This means that some parts of Earth are quite cold while other parts are downright hot. To speak of the "average" temperature, then, may seem like nonsense. To calculate a global average temperature, scientists begin with temperature measurements taken at locations around the globe.
