Scientists rule out best and worst predictions for global warming

Scientists have narrowed down the range of possible future outcomes related to climate change, ruling out both the direst projections and more optimistic ones that suggest a rapid decline in greenhouse gas emissions. In a new study published in the journal Nature Climate Change, researchers from the United Kingdom's Met Office Hadley Centre found that while global warming is still inevitable due to past emissions, the level of future warming will be significantly influenced by current and near-future policies aimed at reducing carbon dioxide (CO2) emissions. The research team used a statisti…
