Half a degree more global warming could flood out 5 million more people. A new study finds that by 2150, the seemingly small difference between a global temperature increase of 1.5 and 2.0 degrees Celsius would mean the permanent inundation of lands currently home to about 5 million people, including 60,000 who live on small island nations.

That reminds me of the movie "Water World" and how difficult it was to survive. If we are going warmer we are also going wetter except its not the kind of "Wet" we want.

First direct observations of methane's increasing greenhouse effect at the Earth's surface. Scientists have directly measured the increasing greenhouse effect of methane at the Earth's surface for the first time. A research team has tracked a rise in the warming effect of methane - one of the most important greenhouse gases for the Earth's atmosphere - over a 10-year period. Source 5s.
Study reveals new Antarctic process contributing to sea level rise and climate change. A new study has revealed a previously undocumented process where melting glacial ice sheets change the ocean in a way that further accelerates the rate of ice melt and sea level rise. The research found that glacial meltwater makes the ocean's surface layer less salty and more buoyant, preventing deep mixing in winter and allowing warm water at depth to retain its heat and further melt glaciers from below.

Global warming of 1.5°C or 2°C: The lower limit would reduce flood hazards. A research group has simulated the scenarios of limiting global warming to 2°C versus 1.5°C with global hydrological models. An important result: High flows and flood hazards will increase significantly over an average of 21 percent of global land area if the temperature rises by 2°C. But if the rise in global warming is limited to 1.5°C only 11 percent of global land area would be affected. Source 4x.
Earth just had its 400th straight warmer-than-average month thanks to global warming. Last month marked the planet's 400th consecutive month with above-average temperatures, federal scientists from the National Oceanic and Atmospheric Administration announced Thursday. The last time Earth had a cooler-than-average month was back in December 1984, when President Reagan had just been elected to his second term, “Dynasty” was the top show on TV and Madonna's “Like a Virgin” topped the musical charts.

When the storms start to roll in they may get bigger and more destructive that Harvey and the like. Its scary to think about since Puerto Rico hasn't fully recovered from that yet. This is where people need to see what global warming is doing… its not just getting hotter but it will cause lots of climate changes that bring destruction.
