In summary, these results demonstrate the potential for synergies and sensitivities of ecological response to forest loss in disparate regions via ecoclimate teleconnections, which will need to be accounted for as global forest loss increases and climate dynamics are altered in response to land use and climate change.
When you claim that a nation such as the United States which emits high levels of ghgs need not adopt climate change policies because adverse human - induced climate change impacts have not yet been proven, are you claiming that climate change skeptics have proven that human - induced climate change will not create harsh adverse impacts to the human health and the ecological systems of others on which their lives often depend and if so what is that proof?
