Not only for heating: Climate change signs can be seen around

WASHINGTON – YOU don’t just feel the heat of the warming of the earth you see him in action in the round.

Some examples of where climate change effects have been measured:

—The glaciers in the world are melting and retreating, with 279 billion tons of ice lost since 2002, according to NASA’s GRACE satellite. Jakobshavn Glacier in Greenland flows faster than any other glacier on Earth. In 2012, it hit a record pace of about 75 centimeters per hour (1.9 meters). In 2017, slowed down to 40 centimeters per hour (1 meter). The Portage Glacier in Alaska has retreated and cannot be seen from the visitor centre, which opened in 1986.

—In the Rocky Mountains, the first robins of spring to come 10.5 days earlier than it was 30 years ago. The first larkspur wildflower is up to eight days sooner and the marmots come out of hibernation five days earlier, according to data collected by the Rocky Mountain Biological Lab.

—On average over the past 30 years, there are more major hurricanes (those with winds of more than 110 km / h), they have lasted longer and they produced more energy than the previous 30 years, according to an Associated Press analysis of the storm data. Other studies have shown that the first named storm in the Atlantic ocean forms almost a month earlier than 30 years ago and the storms move more slowly, allowing more rain to fall.

—All Over the world, seas have risen by about 3 inches since 1993. That doesn’t sound like much, but it is enough for the entire United States in the water about 9 feet deep. Places like Miami Beach, Florida, and Norfolk, Virginia, and flooding, often with high tides.

—The number of acres burned in the U.S. by wildfire has doubled in comparison with 30 years ago. Last year, more than 10 million acres burned. Over the last five years, with an average of 6.7 million acres burned a year. From 1984 to 1988, approximately 2.8 million years burned, on the average.

—Allergies have gotten worse with longer growing seasons and more potent pollen. High ragweed pollen days have increased by between 15 and 29 days since 1990 in a swathe of the country from Oklahoma City north to Winnipeg, Canada, according to a U.S. Department of Agriculture research.

—In the west of the United States, the cute rodent called the pika should be back around freezing for the most part of the year. But these habitats are becoming smaller, leading to higher located areas. University of Colorado’s Chris Ray, a pika expert, said they have not definitively linked climate change to a dramatic decline in pika populations, but they found that they are gone more from places that are warming and drying.

—Extreme one-day precipitation in the country has increased by 80 percent over the past 30 years. Ellicott City, Maryland, had the so-called thousand-year floods in 2016 and this year. Floods in Louisiana, West Virginia and Houston in 2016, South Carolina, Texas and Oklahoma in 2015, Michigan and parts of the Northeast in 2014, has already led to more than $ 1 billion in damage, according to the National Oceanic and Atmospheric Administration.

—The number of polar bears in parts of Alaska have fallen 40 percent since the late 1990s. When scientists have weighed the polar bears recently in some locations, they were the loss of 2.9 to 5.5 pounds per day in a time of the year in which they were supposed to be putting on weight.

Warmer water is repeatedly causing mass global bleaching events on Earth the fragile coral reefs. Before 1998, there was no global mass bleaching events — which, in turn, the living coral, white, and often lead to death. But there are three in the last two decades. The U.S. government coral reef specialist Mark Eakin said for multiple reasons, including the warming of the earth, “most of the reefs are in great shape in the 1980’s in Florida are just barely hanging on now.”
