On a more serious note now, I don't believe any professional scientist is suggesting that every year the Earth is going to warm another five degrees or so. As the above graph showing the instrumental record of global average temperatures displays, compiled by the Climatic Research Unit of the University of East Anglia and the Hadley Centre of the UK Meteorological Office, the global average air temperature near Earth's surface has risen 1.62 degrees Fahrenheit during the last century. So, of course, that doesn't mean snow anywhere in the United States during April except in the Rocky Mountains, Duluth, Minnesota or the Northeast is unheard of now.
1.62 degrees obviously won't generate any dramatic immediate effect on weather patterns here or elsewhere, in that manner. But 1.62 degrees can make a dramatic effect outside the box. As this above graph archived at the World Glacier Monitoring Service at the National Snow and Ice Data Center reveals, what's called the glaciological mass balance, found by measuring the annual snow growth and subtracting surface ablation driven by melting, sublimation and wind erosion, has dramatically thinned in recent years, and in result great glaciers such as Montana's cherished Grinnell Glacier have been retreating, where one photograph of the glacier taken by T.J Hileman in 1938 reveals ubiquitous snowpack and blankets of frost, contrats sharply from a 2005 photograph of the same glacier taken by Blase Reardon, where the former sight of dense snowpack located in Hileman's picture is now like a lake, with many of its environmental surroundings those which could be mistaken for the Grand Canyon.
When we look at glaciers, often they may seem phlegmatic, inactive, solid as a statue, so we can easily get the feeling the mere melting of a glacier won't affect us in any way. But other than, obviously, the rising of sea levels in result of the melting of glaciers and ice shelf disruptions, which can disrupt any community at or near sea level, agricultural communities that depend on these glaciers and dense icepacks for water and the hydration of their crops will suffer, as the climate indeed has a direct influence on global food supplies. Traditionally colder areas of the world like much of Russia and the Northwest Territories of Canada may actually be an exception that benefits from an average rise in global temperatures in terms of agriculture, but world communities that depend on these glaciers as an essential resource will be devastated, where land becomes increasingly arable, soil degradation is more likely to occur, fungal diseases are more rampant and, in result, famine and desertification occur. The Yangtze River valley of China is one central example.
So, to conclude, it's certainly no surprise to me that snow continues to fall in April across much of America (back when I lived in Colorado, in 1993 I remember seeing snow on the first week of June). Weather patterns aren't going to dramatically alter every single year from the greenhouse effect. But in the larger sense, I do believe there's an overwhelming mountain of evidence that points to a greater problem worldwide, and if we don't begin to try mitigating these effects, we too will likely feel the sting of global warming especially in terms of agriculture and our economy, where in these last five years we've in fact been suffering setbacks in certainly not all, but many harvests of certain crops because of intense heatwaves and drought.
