Yes. Earth is currently screening numerous symbols of worldwide climate change.
Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) all over the world since 1880, a good bit of this in recent decades, in accordance with NASA's Goddard Institute for Space Studies.
The interest rate of warming is rising. The 20th century's last twenty years seem to have been the hottest in 400 years and possibly the warmest for numerous millennia, according to various climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the previous 12 years may be among the many dozen warmest since 1850.
The Arctic is feeling the consequences the most. Average temperatures in Alaska, western Canada, in addition to eastern Russia have risen at double the global average, according to the multinational Arctic Climate Effect Assessment report compiled within 2000 and 2004.
Arctic ice is rapidly disappearing, and the district may have the first of all wholly ice-free summer by 2040 or even earlier. Polar bears and indigenous cultures are already tormented by the sea-ice damage.

People are pouring carbon dioxide to the atmosphere much quicker than plants and oceans might absorb it.
These gases persist in the surroundings for years, that means that even if the mentioned emissions have been eliminated now, it might not instantly finish global warming.
Many professionals indicate that organic cycles in Earth's orbit might change the planet's hype to sunlight, which might clarify the current model. Earth have certainly experienced warming and cooling cycles harshly every hundred thousand years because of those orbital shifts, but such alterations have occurred along the span of several centuries. Today's alterations have taken place over the past hundred years or fewer.
What's Going to Happen?
A follow-up describe warned that global warming could lead on to large-scale food and water shortages and still have catastrophic effects on nature.
Sea level could mount within 7 and 23 inches (18 to 59 centimeters) by means of century's end. Rises of just four inches (10 centimeters) might flood a number of South Seas islands and swamp big parts of Southeast Asia.
Glaciers around the world could melt, inflicting sea levels to rise while creating water shortages in areas depending on runoff for clean water.
Powerful hurricanes, droughts, heat waves, wildfires, as well as other natural disasters may turn out to be conventional in many parts of the world. The expansion of deserts may also cause food shortages in lots of areas.
More than 1 000 000 species face extinction from disappearing territory, changing ecosystems, and acidifying oceans
