6. -Climate changes characterized as global warming are leading to large-scale irreversible effects at continental and global scales. The likelihood, magnitude, and timing is observed to be increasing and accelerating. -Large reductions in the Greenland and West Antarctic Ice Sheets , accelerated global warming due to carbon cycle feedbacks in the terrestrial biosphere , and releases of terrestrial carbon from permafrost regions and methane from hydrates in coastal sediments are accelerating. -Most of the consequences of global warming would result from physical changes: sea level rise, higher local temperatures, and changes in rainfall patterns, oceans forests and species dying off create many unforeseen impacts such as a decrease in the amount of oxygen in the earth's atmosphere. -Sea level is generally expected to rise 18 to 59 cm (7.1 to 23.2 inches) by the end of the 21st century.

15. Storm strength leading to extreme weather is increasing, such as the power dissipation index of hurricane intensity . Hurricane power dissipation is highly correlated with temperature, reflecting Increases in catastrophes resulting from extreme weather are mainly caused by increasing population densities, and anticipated future increases are similarly dominated by societal change rather than climate change As the climate grows warmer and the causes of global dimming are reduced, evaporation will increase due to warmer oceans. World is a closed system this will cause heavier rainfall , with more erosion . This erosion lead to vulnerable tropical areas (especially in Africa) to desertification . Other areas, increased rainfall lead to growth of forests in dry desert areas. Over the last 50 years. Canada , Alaska and Russia are experiencing initial melting of permafrost . This may disrupt ecosystems and by increasing bacterial activity in the soil lead to these areas becoming carbon sources instead of carbon sinks CLIMATE

25. SEA LEVEL RISE With increasing average global temperature, the water in the oceans expands in volume, and additional water enters them which had previously been locked up on land in glaciers, for example, the Greenland and the Antarctic ice sheets . For most glaciers worldwide, an average volume loss of 60% until 2050 is predicted. [ The sea level has risen more than 120 metres since the Last Glacial Maximum about 20,000 years ago. The bulk of that occurred before 7000 years ago. [ From 3000 years ago to the start of the 19th century, sea level was almost constant, with only minor fluctuations. However, the Medieval Warm Period may have caused some sea level rise; evidence has been found in the Pacific Ocean for a rise to perhaps 0.9 m

29. GLACIER MELTING Total surface area of glaciers worldwide has decreased by 50% since the end of the 19th century. [ Currently glacier retreat rates and mass balance losses have been increasing in the Andes , Alps , Pyrenees , Himalayas , Rocky Mountains and North Cascades . The loss of glaciers not only directly causes landslides, flash floods and glacial lake over flow, but also increases annual variation in water flows in rivers. Glacier runoff declines in the summer as glaciers decrease in size, this decline is already observable in several regions. [ Glaciers retain water on mountains in high precipitation years, since the snow cover accumulating on glaciers protects the ice from melting. In warmer and drier years, glaciers offset the lower precipitation amounts with a higher melt water input. [ Of particular importance are the Hindu Kush and Himalayan glacial melts that comprise the principal dry-season water source of many of the major rivers of the Central , South , East and Southeast Asian mainland. Increased melting would cause greater flow for several decades, after which "some areas of the most populated regions on Earth are likely to 'run out of water'" as source glaciers are depleted. [
