Impact of pollution, climate change - lethal heat waves threaten third of world population, 75 percent by 2100

Deadly Heat Waves Threaten Third of the World
Currently, nearly a third of the world's population is exposed to lethal climate conditions for at least 20 days a year, according to findings published Monday in Nature Climate Change, a monthly peer-reviewed journal. As the planet's temperature rises, more of the world's population will be exposed to conditions that trigger deadly heat waves, the report said.
For a city like New York, which currently sees about two days per year that surpass the heat threshold, that could mean 50 deadly days per year by 2100.
The researchers analyzed more than 1,900 cases of fatalities associated with heat waves in 164 cities across 36 countries between 1980 and 2014 to define a global threshold for life-threatening conditions based on heat and humidity. Researchers found the overall risk for heat-related sickness or death has increased steadily since 1980.
The study notes well-documented heat waves, including a five-day stretch that claimed hundreds of lives in Chicago in 1995, the European heat wave in 2003 that saw tens of thousands of heat-related deaths and lethal temperatures in Moscow in 2010 that killed more than 10,000. Across Russia, the heat wave in 2010 claimed more than 50,000 lives. But the research team found that heatwaves are more common than most people think, and humidity levels combined with heat play a major role in heat-related heath risks. read more »
1958–2009. CO2 in atmosphere up 24% in 50 years from 310 to 384; upper limit is 350 ppm, realtime evident indicator

To see whether enough is being done at the moment to solve these global problems, there is no single indicator as complete and current as the monthly updates for atmospheric CO2 from the Mauna Loa Observatory. Carbon dioxide (CO2) is the chief greenhouse gas that results from human activities & CO2 levels rising in the Earth’s atmosphere causes global warming and climate change. Both atmospheric CO2 and climate change are accelerating. Climate scientists say we have YEARs, not decades, to stabilize CO2 and other greenhouse gases. To help the world succeed, CO2Now.org makes it easy to see the most current CO2 level and what it means. So, use Earth's CO2 Home Page & keep an eye on CO2.
Leader's vision & commitment. Oscar Arias and Costa Rica: planted 6.5 million trees by 2007 while spending $0 on military
(quote)
Costa Rican President Oscar Arias planted the 5 millionth tree of the year near his office in the capital San Jose, By the end of 2007, Costa Rica has planted nearly 6.5 million trees, which should absorb 111,000 tonnes of carbon dioxide a year. The goal for 2008 was to plant 7 million trees as part of the newly launched project in order to make the biodiversity nation carbon neutral. Costa Rica constitutionally abolished its army permanently in 1949.
Greenland ice melting 3 times faster, loss of vast ice sheet & weight which affects Earth gravitational pull

Greenland ice cap melting at triple the rate of just a decade ago
Greenland ice cap is disappearing at the rate of 300 Lake Windermeres a year. More than 273 gigatons of water is now pouring into the oceans annually, raising sea levels by nearly a millimeter every year, satellite imaging has shown. Such is the change in the vast ice sheet that the loss of weight is actually changing its affect on the earth's gravitational pull, the study in Science claims. One gigaton could provide enough water for 17 million people in Britain and is the volume of Lake Windermere, Britain's biggest water mass.
World Vegan Day & Vegan month: plant-based diet vs meat-eating diet, which way health-wise? Your choice.
November is US National Vegan Month, starting with World Vegan Day on Nov. 1st. So, turkeys may have less fear this year though Thanksgiving is around the corner. Why go vegan? Here are some alarming facts, or "tough reality", such as – fewer than 1 out of every 250,000 slaughtered animals is tested for toxic chemical residues; 55% of U.S. antibiotics is fed to livestock; 91% of staphylococci infections are resistant to penicillin in 1988; BAN is the response of European Economic Community to routine feeding of antibiotics to livestock while the response of U.S. meat & pharmaceutical industries is full & complete support. The world’s meat consumption was estimated to be 284 million tons in one year (2007), and it takes 5,000 gallons of water to produce a pound of California beef, compared to 25 gallons to produce a pound of wheat.
Heart disease is number one killer, but one can reduce heart-attack risk by 90% just by eliminating meat, dairy and eggs from diet. In other words, 5000 gallons of water can be spared and risk of heart attack can be lessened when one eats one less pound of meat.

Melting of ice sheets in Greenland and West Antarctica, a 3-foot rise in sea level by 2100?
(quote)
For years, scientists have talked about rising sea levels due to global warming - both from warm water expanding and the melt of ice sheets in Greenland and West Antarctica. Predictions for the average worldwide sea rise keep changing along with the rate of ice melt. Recently, more scientists are saying the situation has worsened so that a 3-foot rise in sea level by 2100 is becoming a common theme.
