叙利亚的伊斯兰组织发布了一段网络视频,该组织声称,里面有5名专门被派往叙利亚协助与叛军作战的也门工作人员。视频展示了这5个人的身份证,其中一名看上去是陆军中校。也门的一个权利组织辨认他们是在阿勒颇一个军事学院学习的军方官员,他们的家人已于上月报告他们失踪。
Research into the effects of global warming suggests that the size of fish around the world could shrink dramatically over the next few decades. Warmer ocean temperatures could lead to hundreds of types of fish losing up to 1/4 of their body weight. Here's Matt McGrath.Although projections of global temperature rises show relatively small changes at the bottom of the oceans, the resulting impacts on fish body size are unexpectedly large, according to this research. As ocean temperature increases, so do the body temperatures and metabolic rates of the fish. This means they use more oxygen to stay alive. And according to the researchers, they have less available for growth.
对全球变暖后果的研究结果表明,全世界鱼的数量在未来50年可以会急剧下降。上升的海洋温度可能会导致上百种鱼的重量减轻1/4。Matt McGrath报道。 根据这一研究,尽管全球气温升高对海洋底部的影响相对来说较小,对鱼的重量的影响却出乎意料的巨大。随着海洋温度的增加,鱼的身体温度升高,新陈代谢的速度也加快了。这就意味着,为了保持活着的状态,这些鱼得使用更多氧气,这些研究者们认为,这样他们用来生长的氧气便减少了。
