Imagine a nice day, 70 degrees, scattered clouds, maybe the wind is gently blowing, maybe there are some flowers nearby. That is winter on an Earth suffering from global warming. Now, go to summer: Imagine a desert, a sweltering 130 degrees, dry dust and sand everywhere. Hot, dry winds choking a parched landscape. It rarely rain, but when it does, imagine taking a drink of water, swallowing a little bit, and then being forced to spit the rest of it out. It is only enough to just barely keep the plants around here alive. For many animals, including humans, this environment is almost entirely uninhabitable. The Earth is at a crucial moment, and unless something is done about global warming right now, this will not only be the harsh reality, but it will also be humanity"s fault.
Researchers have been drafting a summary for the Intergovernmental Panel on Climate Change (IPCC), and are now 95% certain that more than half of global warming is being caused by human emissions of greenhouse gases. Scientists were already 90% certain in 2007, but in 2013, that certainty increased to 95%. Although some might point out that that the Earth has barely gotten warmer since 1998, that is not a valid argument, because although it is true, there have been other forces contributing to the slowing of global warming. One is El Nino and La Nina, which are complex weather patterns caused by varying temperatures in the Equatorial Pacific. El Nino, the warm phase, was very strong in 1998, while in the past few years, El Nina, the cold phase, has been stronger. Another reason the warming has slowed is because of the longer solar cycles, where the sun gets warmer and cooler. In the past few years, the Sun has been going through a longer cool period than predicted. While some of these signs are subtle, others are not so subtle, such as glacial melting.
The glaciers have been melting since the Little Ice Age ended in about 1850, which is natural, as the Earth goes through cycles of warm and cold. But what isn"t natural is the rate at which the glaciers have been melting. From 1851 to 2010, 25% of glacier mass being lost was due to human activity, but between 1991 and 2010, 69% of glacier mass being lost was due to human activity. Some might say "but what about the polar vortex? That was cold!" and although that is true, new research suggests that the polar vortex may have come south because of glaciers melting. "Normally, sea ice keeps heat energy from escaping the ocean and entering the atmosphere. When there's less ice, more energy gets into the atmosphere and weakens the jet stream, the high-altitude river of air that usually keeps Arctic air from wandering south, said study co-author Jin-Ho Yoon of the Pacific Northwest National Laboratory in Richland, Wash. So the cold air escapes instead"(SIRS). In the 90"s, this was not a very frequent occurrence, but since 2000, it has happened almost every year. Some might say that the Earth is trying to warn humanity before something terrible happens
When the Earth warms at an unprecedented rate, it can trigger extreme weather events. Case and point, the polar vortex that walloped much of the United States. Other extreme weather events have been experienced as well. Droughts are getting longer, the risk of wildfires has increased, heat waves are popping up out of nowhere, and there has been extreme precipitation in some places. Int the year 2012, the hottest on record for the United States,these extremes were experienced firsthand, with widespread drought and extensive wildfires.
Human activity is causing global warming. Glaciers are melting, the weather has gone haywire, and the Earth is trying to warn everyone before it"s too late, and if mankind continues turning up the heat, someone is going to get burned.
To begin, I would like to point out contradicting evidence in your argument. You write in your opening that, " Imagine a desert, a sweltering 130 degrees, dry dust and sand everywhere. Hot, dry winds choking a parched landscape. It rarely rain". How does this imagery seem accurate, when you later provide evidence that there have been higher precipitation rates around the world, "there has been extreme precipitation in some places".
You also state that the IPCC has evidence that global warming is being caused by greenhouse gases. 31,000+ scientists and researchers from the Oregon Institute of Science and Medicine, as well as hundreds of thousands more elsewhere, say otherwise. As they put it, "limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind. There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth."  Think also to the process of photosynthesis in plants to clarify this. Plants absorb carbon dioxide and water, and using the energy from the sun produce sugar and oxygen. Any carbon dioxide produced can be used by the trillions of plants currently calling Earth home.
We must also examine the composition of the atmosphere to clear up any modern misconceptions. The three main compounds in the atmosphere are diatomic molecules of Nitrogen, making up 78.08% of our atmosphere, followed by Diatomic molecules of Oxygen with 20.95%, then Argon comprising 0.93%. That already accounts for 99.93% of our atmosphere. The other .7% is made up of Water Vapor, Methane, Ozone and Aerosols, along with carbon dioxide. Good Old CO2 only comprises 0.036% of our atmosphere. 
You also say that there are global heating and cooling trends, which is fact. Another fact can be explained by writer Peter Ferrara, "natural climate cycles have already turned from warming to cooling, global temperatures have already been declining for more than 10 years, and global temperatures will continue to decline for another two decades or more."  There has also been significant evidence that shows that ice has been forming near the south pole, not melting. Mark Serreze and his team at the National Snow and Ice Data Center say, "[any] warming of the planet is in fact behind a paradoxical growth in South Pole sea ice...The primary reason for this is the nature of the circulation of the Southern Ocean " water heated in high southern latitudes is carried equatorward, to be replaced by colder waters upwelling from below, which inhibits ice loss," 
Your argument that droughts are being caused by "global warming" is also false. Several scientists and authors compiled their evidence and write, "Confounding the analysis...[there] is multiyear and even multidecadal variability likely caused by both large-scale atmospheric circulation changes and basin-scale "memory" in the form of soil moisture. Droughts also have long-term trends as well as multiyear and decadal variability." 
In arguing that humanity is the cause of heating trends in the atmosphere, you have provided no evidence affirming this. You merely provide evidence that proves that the Earth experienced a phase, and show no evidence that any stated change is caused by man. In the end, the only person being burned by the entire issue of global warming is you.
Back to you.
