Arctic sea ice extent both affects and is affected by global climate change. An interactive exploration of how global warming is affecting sea ice, glaciers and continental ice sheets worldwide. Below are some of the impacts that are currently visible throughout the U.
Global Change Research Program :. Heat waves, heavy downpours and sea level rise pose growing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries and ecosystems will be increasingly compromised. Many states and cities are beginning to incorporate climate change into their planning. Changes in the timing of streamflow reduce water supplies for competing demands.
Sea level rise, erosion, inundation, risks to infrastructure and increasing ocean acidity pose major threats. Increasing wildfire, insect outbreaks and tree diseases are causing widespread tree die-off. Extreme heat will affect health, energy, agriculture and more. Decreased water availability will have economic and environmental impacts.
Extreme heat, heavy downpours and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also exacerbate a range of risks to the Great Lakes. Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires.
Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns. Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time. An indicator of current global sea level as measured by satellites; updated monthly. GISS climate models. Climate Time Machine.

Precipitation quiz. Such tipping points are expected for the melting of the polar caps and for the stability of important ocean currents. You can find further exciting information on the subject of climate change and climate protection in our climate booklet. Offset now. What are the effects of climate change and global warming? Related articles What are climate offset projects? Is the climate change caused by humans? What does climate change mean?
Climate change will almost certainly cause more droughts, particularly in Northland and the East Cape. It will mean increased rainfall in other areas, particularly the West Coast, and an increased risk of flooding. Coastal areas will face greater erosion, and possible inundation. People around the world are already feeling the impacts of climate change.
Water supplies are shrinking, crop yields are dropping, forests are burning, and our oceans are becoming more acidic. This has huge implications for our livelihoods and human security. Fragile ecosystems, like coral reefs, are also already succumbing to climate change impacts. Melting glaciers, rising sea levels, and new and more frequent weather extremes will leave no continent untouched.
If we let the warming continue unchecked, we run a real risk of hitting catastrophic tipping points. That's where the warming triggers positive feedback loops that lead to even more warming.
To avoid the worst impacts of climate change, scientists warn that average global temperatures should not be allowed to rise more than 1. When the world's governments committed to the Paris Agreement in - a new, global deal on climate change - they answered a call from our Pasifika neighbours, and agreed to try to keep warming below 1.
A rise in temperature above 1. Thing is, this won't just stop climate change. Switching from dirty fossil fuels to clean renewable energy will be better for people, communities and businesses all over the world. And the change is already underway. Renewable energy technologies like wind and solar are getting cheaper and cheaper, and rolling out worldwide faster and faster. We can do this. Causes of climate change Climate change is happening because of us. This climate change is because of human activity The main causes of climate change are:.
