To get useful answers to your questions, it's crucial to be clear and specific about what you're asking. Provide context and relevant details to help others understand your inquiry fully. Research your question beforehand to ensure it hasn't been answered already, and ask in the appropriate forum or to the right person. Be respectful and courteous in your approach, encouraging others to engage with your query. Lastly, be open-minded and willing to consider different perspectives or solutions. By following these guidelines, you increase the likelihood of receiving insightful and helpful responses to your questions.
Getting useful answers to your questions often depends on how you frame your inquiries and how you engage with the person you're asking. Here are some tips:
1. Be Clear and Specific: Make sure your question is clear and specific to avoid ambiguity. Vague or overly broad questions can lead to unclear or irrelevant answers.
2. Provide Context: Offer context or background information to help the person understand the purpose of your question. This can lead to more relevant and insightful answers.
3. Ask One Question at a Time: Avoid asking multiple questions in one go, as this can overwhelm the person and make it difficult for them to provide a focused response. Ask one question at a time and wait for a complete answer before moving on to the next one.
4. Listen Actively: Pay attention to the person's response and listen actively. Avoid interrupting or jumping to conclusions. This shows respect and encourages the person to provide more detailed and thoughtful answers.
5. Encourage Elaboration: If the person's answer is brief or unclear, ask follow-up questions to encourage them to elaborate further. This can help uncover additional insights and perspectives.
Forests are feeling the heat. In places like the American West, rising temperatures and drought mean less water for trees, sometimes shriveling swaths of woodland. Now, scientists have found that thinning early in forest growth creates tougher trees that can endure climate change. What's more, these thinned forests can suck carbon out of the air just as fast as dense forests.
"When it comes to carbon sequestration and climate change adaptation, we can have our cake and eat it too," says Andrew Larson, forest ecologist at the University of Montana in Missoula and author of the new study. "It's a win-win."
As trees grow, they convert carbon dioxide to food and store it in their leaves, trunks, and roots. U.S. forests capture between 10% to 20% of U.S. emissions each year. But if trees get too crowded, they compete for light and water—and stressed trees are more susceptible to drought and insect attacks. Removing some trees can ease the competition, letting the remaining trees grow big and healthy. But scientists worry that removing trees can reduce forest carbon storage. These worries, however, are based mostly on models and short-term studies.
To see if the climate trade-off truly exists, scientists tapped into a long-term experiment in northwestern Montana. In 1961, U.S. Forest Service officials started the experiment in a young forest of western larch—a conifer common in the Inland Northwest. The forest was broken up into plots. In some plots, the 8-year-old trees were thinned from tens of thousands per hectare down to 494 per hectare (2.5 acres). These trees grew thick trunks and broad canopies. Other plots were left alone, and the teeming trees grew tall and skinny as they competed for sunlight. The original study was rooted in an interest in growing timber rapidly. But the scientists at the University of Montana sprouted a new question: How did tree density affect carbon storage?
The Amazon rainforest’s trees may soon die off en masse, researchers warn. According to a 20-year satellite study published yesterday (March 7) in Nature Climate Change, the famous forest is exhibiting signs of poor health that could mean large portions of it will become savannah in the near future. Such an ecological shift could happen quickly, Timothy M. Lenton, a coauthor on the study and a director of the Global Systems Institute at the University of Exeter, tells CNN. “My hunch, for what it’s worth, (is that) it could happen in the space of decades.”
“The Amazon is a custodian of biodiversity and possesses a vital ability to pull in carbon dioxide from the atmosphere, so it is clearly concerning that its health is deteriorating as human-caused deforestation and climate change metes out increasingly potent and harmful impacts on the ecosystem,” University of Reading climate scientist Richard Allan, who was not involved in the study, says in a statement to the Science Media Centre (SMC).
