Climate Minute: Local, state, and national opinions on global warming
SAN ANTONIO โ The consensus among scientists around the world is that climate change, including global warming, is happening and that humans are contributing due to greenhouse gas emissions. But do you know how your personal opinions on climate change compare to those around your local county, the state of Texas, and the nation? An extensive national study conducted by Yale University is highlighting the differences of opinions on climate change around the nation. From the study, the university created an interactive map where you can see answers to various questions about climate change and global warming. Here are some interesting takeaways:BeliefsGlobal warming is happeningOn a national level 72% of people believe global warming is happeningHowever, in Bexar County, itโs estimated that 80% of people believe global warming is happening.
UN: World could hit 1.5-degree warming threshold in 5 years
GENEVA The world could see average global temperatures 1.5 degrees Celsius (2.7 Fahrenheit) above the pre-industrial average for the first time in the coming five years, the U.N. weather agency said Thursday. The 1.5-C mark is the level to which countries have agreed to try to limit global warming. Scientists say average temperatures around the world are already at least 1 C higher now than during the period from 1850-1900 because of man-made greenhouse emissions. The World Meteorological Organization said there is a 20% chance that the 1.5 C level will be reached in at least one year between 2020 and 2024. The period is expected to see annual average temperatures that are 0.91 C to 1.59 C higher than pre-industrial averages.
Fish more vulnerable to warming water than first thought
Global warming looks like it will be a far bigger problem for the worlds fish species than scientists first thought, since a study led by Dahlke released on Thursday, July 2, 2020 shows that when fish are spawning or are embryos they are far more vulnerable to hotter water. (Dr. F. Dahlke via AP)Global warming looks like it will be a bigger problem for the worlds fish species than scientists first thought: A new study shows that when fish are spawning or are embryos they are more vulnerable to hotter water. For adult fish, around 2% to 3% of the species would be in the too-hot zone in the year 2100 with similar projected warming. So using this new approach reveals a previously unknown problem for the future of fish, scientists said. With spawning fish and embryos most sensitive to warming waters, it means fish populations wont be able to replace themselves, said Rutgers University ecologist Malin Pinsky, who wasnt part of the study but praised it.
