Earliest Blooms Recorded in U.S. Due to Global WarmingArticle: Plants still able to cope with rising temperatures, study finds. http://news.nationalgeographic.com/news/2013/01/130116-spring-earlier-global-warming-plants-trees-blooming-science?utm_campaign=Content&utm_content=link_tw20130118news-flowerblooms&utm_medium=Social&utm_source=Twitter In 2010 and 2012. I know I missed blackberry season. Just about the normal time for blackberries, I asked a few people if they'd seen any and I was told I'd missed them. In 2011, it was big news in Wisconsin and Minnesota that the cold tolerance zones had been adjusted for the warmer weather and they could plant some non native things they hadn't been able to before. But there wasn't much talk about how this isn't necessarily a good thing. It means new species invade. It means old species die out in that area. And some species might not get the cold period they need so they know when it's warming up and time to sprout or bloom.
