Why is climate change happening now. The Arctic is one of the ecosystems most vulnerable to the effects of climate change as it is warming at least twice the rate of the global average and melting land ice sheets and glaciers contribute dramatically offsite link to sea. No one is terribly sure about what will. The speed of the current climate change is faster than most of the past events making it more difficult for human societies and the natural world to adapt.
Glaciers have shrunk ice on rivers and lakes is breaking up earlier plant and animal ranges have shifted and trees are flowering sooner. This ancient or paleoclimate evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming. One to 2 degrees Celsius of warming can do a lot of damage.
I think that climate change activity is happening because the greenhouse gases that humans are producing are making sea levels go up natural changes in the suns activity cannot explain global warming and ocean temperatures are going up at an unbelievable rate due to global warming. Global climate change has already had observable effects on the environment. Climate change will continue to have a significant impact on ecosystems and organisms though they are not impacted equally.

Ad Climate Change Destroys Homes and Lives. High temperature extremes and heavy precipitation events are increasing glaciers and snow cover are shrinking and sea. Thousands of studies conducted by researchers around the world have documented increases in temperature at Earths surface as well as in the atmosphere and oceans.
Chunks of ice in the Antarctic have broken apart. The World Economic Forums Global Risks Report continues to rank these environmental threats at the top of the list. In just the past few decades.
Be Part Of The Solution Now. It is the rapid rate and the magnitude of climate change occurring now that is of great concern worldwide. Loss of sea ice accelerated sea level rise.
Help Us Protect Your Community. Communities around the world are already experiencing increased climate impacts from droughts to floods to rising seas. Past climate changes led to extinction of many species population migrations and pronounced changes in the land surface and ocean circulation.
Climate change poses an urgent threat demanding decisive action. But large-scale changes in climate have occurred before some gradual and some extremely rapid. Our actions will help determine the Earths future.
