Causes of Global Worming

Most climate scientists agree the main cause of the current global warming trend is human expansion of the "greenhouse effect"1warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.

A real global warming solution‎

Archangel Ancient Tree Archive is providing a real global warming solution. By locating and propagating trees with ancient and “champion” genetics that have the best chance for survival, and by reintroducing these trees back into the environment, we may be able to overcome the onslaught of environmental challenges we are facing today and will increasingly face in the future. We are working to preserve the genetics of the last remaining representatives of our old-growth forests, and hope to give science a chance to study the yet unknown benefits of these trees before they blink off the face of the earth.
It is absolutely critical that these trees get replanted to strengthen our urban and rural forests. Planting champion trees introduces selected traits back into nature to strengthen the remaining forests. When they cross-pollinate with existing trees the resulting saplings will have some of the characteristics from the Champion Trees.
We will measure our success, in part, by the number of these trees planted in the environments that will have the greatest beneficial impact. We hope to partner with like-minded organizations to propagate and plant millions of trees from many different origins and species.
Working together to help our environment in a meaningful way gives us hope for the future.

Effects of Global worming

The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases. There is a scientific consensus that climate change is occurring, and that human activities are the primary driver.[1] Many impacts of climate change have already been observed, including glacier retreat,[2] changes in the timing of seasonal events[2] (e.g., earlier flowering of plants),[3] and changes in agricultural productivity.[2]
Future effects of climate change will vary depending on climate change policies[4] and social development.[5] The two main policies to address climate change are reducing human greenhouse gas emissions (climate change mitigation) and adapting to the impacts of climate change.[6] Geoengineering is another policy option.[6]

Near-term climate change policies could significantly affect long-term climate change impacts.[4][7] Stringent mitigation policies might be able to limit global warming (in 2100) to around 2 °C or below, relative to pre-industrial levels.[8] Without mitigation, increased energy demand and extensive use of fossil fuels[9] might lead to global warming of around 4 °C.[10][11] Higher magnitudes of global warming would be more difficult to adapt to,[12] and would increase the risk of negative impacts.[13]
