evidence: In March 1990, Cutter Information Corporation (now known as Cutter Consortium) sent questionnaires to 1500 researchers who were on the attendance lists of climate change conferences, and received 331 responses from 41 countries. The survey revealed widespread agreement that global warming is already happening, that it will result in negative impacts such as sea level rise, and that reducing carbon dioxide emissions and halting deforestation is an appropriate response to it. Only 1.9% of respondents predicted that there would be an overall cooling across the next 100 years. There was more disagreement on the strength of future warming: i.e. around 30% believed that there was a less than 50% chance that the warming would reach or exceed 2 °C (3.6 °F) over the next 100 years, while a larger fraction (almost 40%) thought such temperatures were at least 75% likely.[46][21]
