Stunning NASA chart shows how fast the ground beneath our feet is heating up

SOURCE: Think Progress DATE: Aug 22, 2017 SNIP: Global temperatures are rising faster on the land, where we live, than the oceans, where we don’t, NASA charts reveal. Since scientists have long predicted this trend and say it will continue, it’s worth a closer look. Let’s start with the long-term global warming trend. According to NOAA, “Since 1880, surface temperature has risen at an average pace of 0.13°F (0.07°C) every 10 years, for a net warming of 1.71°F (0.95°C).” But the warming is not evenly distributed: “Over this 136-year period, average temperature over land areas has warmed faster than ocean temperatures: 0.18°F (0.10°C) per decade compared to 0.11°F (0.06°C) per decade.” So over the entire record, the land is warming nearly 70 percent faster than the...
NASA shocker: Last month was hottest July, and hottest month, on record

NASA shocker: Last month was hottest July, and hottest month, on record

SOURCE: Think Progress DATE: Aug 15, 2017 SNIP: July 2017 has narrowly topped July 2016 as the hottest July on record, according to a shocking analysis by scientists at NASA’s Goddard Institute for Space Studies (GISS) released Tuesday. As a result, July 2017 is statistically tied with August 2016 (and July 2016) as the hottest month on record. What’s so surprising here is that records for warmest month or year almost invariably occur when the underlying human-caused global warming trend gets a temporary boost from an El Niño’s enhanced warming in the tropical Pacific. But whereas 2016 set its temperature records boosted by one of the strongest El Niño’s on record, 2017 is setting records in the absence of any El Niño at...
Scientists: Earth on Track to Heat Up to Devastating Levels by 2100

Scientists: Earth on Track to Heat Up to Devastating Levels by 2100

SOURCE: AM 980 Radio Canada DATE: November 18, 2016 SNIP: If humans continue on living as they do now, Earth’s temperature will warm by a devastating 5 C by 2100, new research has found, resulting in a world of drought, flooding, ravaged food supply, and disappearing species. Scientists examined the Earth’s history, going back 800,000 years, to project what’s in its future. “So it is very likely that Earth’s larger sensitivity to this interference will lead to a stronger warming than previously thought.” That means climate change could accelerate at a faster pace than expected and would be at risk of pushing past the “temperature envelope” (the comfortable, livable environment suitable for Earth’s inhabitants) that has prevailed for 800,000 years. “For our warming projection, we used a business-as-usual scenario for future greenhouse gas concentrations,” said Friedrich. “Our study projects a warming of about 5.9 C above pre-industrial levels, or in other words another 5 C above present-day temperatures.” A 5 C warmer global average would result in Canada warming up between 8 – 10 C, predicts Edward A. Parson, faculty co-director at UCLA’s Emmett Center on Climate Change and the Environment. While that might sound like a welcome reprieve from Canada’s often-frosty temperatures, Parson predicts the rise has potential to lead to...
