Climate change impact
The global climate is a connected system climate change impacts are felt everywhere. the most important climate change impacts are:
Rising Sea Levels
Climate change impacts rising sea levels. Coastal cities seeing an increased number of flooding events
Melting Ice
Projections suggest climate change impacts within the next years, if not sooner, the world’s glaciers will have disappeared, as will the Polar ice cap, and the huge Antarctic ice shelf.
Greenland may be green again, and snow will have become a rare phenomenon at what is now the world’s most popular ski resorts.
Heatwaves and droughts
Despite downpours in some places, droughts and prolonged heatwaves will become common.
Rising temperatures are hardly surprising, although they do not mean that some parts of the world will not “enjoy” record cold temperatures and terrible winter storms.
Heating disturbs the entire global weather system and can shift cold upper air currents as well as hot dry ones. Single snowballs and snowstorms do not make climate change refutations.
Increasingly, however, hot, dry places will get hotter and drier, and places that were once temperate and had regular rainfall will become much hotter and much drier.
Changing Ecosystems
The world warms, entire ecosystems will move. rising temperatures at the equator have pushed such staple crops as rice north into once cooler areas, many fish species have migrated long distances to stay in waters that are the proper temperature for them.
Farmers in temperate zones are finding drier conditions difficult for crops such as corn and wheat, and once prime growing zones are now threatened
Reduced food security
One of the most striking impacts of rising temperatures is felt in global agriculture, although these impacts are felt very differently in the largely temperate developed world and in the more tropical developing world.
Different crops grow best at quite specific temperatures and when those temperatures change, their productivity changes significantly.
Pest and Disease
Rising temperatures favor agricultural pests, diseases and disease vectors. pest population are on rising and illnesses once found only in limited, tropical areas are now becoming endemic in much wider zones.
Likewise, dengue fever, once largely confined to tropical areas, has become endemic to the entire region. Increased temperatures also increase the reproduction rates of microbes and insects, speeding up the rate at which they develop resistance to control measures and drugs
How we can do to manage climate change
To date, the effort to manage climate change has been a matter of high-level diplomatic negotiations involving states and international organizations with a loud, but largely excluded fringe of NGOs, business groups, and minor political actors.
Climate change is a global challenge and requires a global solution. Greenhouse gas emissions have the same impact on the atmosphere. Consequently, action by one country to reduce emissions will do little to slow global warming unless other countries act as well.
Ultimately, an effective strategy will require commitments and action by all the major emitting countries.at a level that would prevent dangerous anthropogenic interference with the climate system
