Yes, there will probably be some short-term and long-term positive benefits from global warming, but  if a "business as usual" approach to emitting heat-trapping gases is maintained at the present rate, or faster, then the negative costs and impacts of global warming are very likely to far outweigh the positive benefits over the course of this century

Potential effects of global warming include sea level rise, more frequent and more extreme heat waves, intensification of wet and dry regional climate patterns.

No. By a large majority, climate scientists agree that average global temperature today is warmer than in pre-industrial times, and that human activity is the primary contributing factor.

Yes, there are, but the only new process on Earth that has been identified that can account for the significant tipping of Earth's carbon balance is human activity, including deforestation, biomass burning, cement production, and—especially—fossil-fuel emissions.

Yes, human activities exert a cooling influence on Earth in several ways. Overall, this cooling influence is smaller than the warming influence of the heat-trapping gases humans put into the air.

There is overwhelming scientific evidence that Earth is warming and a preponderance of scientific evidence that human activities are the main cause.

Yes, human activities have increased the abundance of heat-trapping gases in the atmosphere, which a large majority of climate scientists agree is the main reason for the 1.5°F (0.85°C) rise in average global temperature since 1880.

Looking for a sustainable alternative to harvesting wild seaweed, a small California company partnered with a commercial oyster grower to test-farm native seaweeds. The crop reduced pollution and buffered local ocean acidification.
