2013 Ties with 2003 as the fourth warmest year on record: NCDC

2013 was the 37th consecutive year (since 1976) with the annual global temperature remaining above average.

Highlights from NCDC Report

  • The combined land and ocean surface temperature was 0.62°C (1.12°F) above the 20th century average of 13.9°C (57.0°F).
  • Currently, the warmest year on record is 2010 with the temperature 0.66°C (1.19°F) above average.
  • 9 of the 10 warmest years since records began in 1880 have occurred in the 21st century.
  • 1990, the third warmest year on record, is the only one of the top 10 records set in 20th century.

Global Land Temperature

The average global land temperature in 2013 was 0.99°C (1.78°F) above the 20th century average and ranked as the fourth highest annually-averaged value on record.

Global Ocean Temperature

Globally-averaged ocean surface temperature in 2013 saw an anomaly of 0.48°C (0.86°F) above the 20th century average, tying with 2006 as the eighth warmest year on record, reported NCDC.

The departure was just 0.04°C (0.07°F) below the record high of 0.58°C (1.04°F), which was set in both 1998 and 2003.

NOTE: The 1901-2000 average combined land and ocean annual temperature is 13.9°C (56.9°F), the annually averaged land temperature for the same period is 8.5°C (47.3°F), and the long-term annually averaged sea surface temperature is 16.1°C (60.9°F).

Billion-Dollar Weather/Climate Disasters

Some 151 weather/climate disasters have occurred between 1980 and 2013, with the overall damages/costs reaching or exceeding $1 billion (including CPI adjustment to 2013). The total cost of these 151 disasters exceeds $1 trillion, according to NCDC.

The 2013 toll of billion-dollar weather and climate disasters across the United States stands at 7 events, which included five severe weather and tornado episodes, a major flood episode, and the western drought/heat wave.

SST Hit Highest Level in 150 Years on Northeast Continental Shelf

Posted by feww on April 29, 2013

SST for the NE Shelf Ecosystem jumped to record 14°C in 2012

Sea surface temperatures (SSTs) in the Northeast Shelf Large Marine Ecosystem during the second half of 2012 hit the highest level in 150 years, according to Northeast Fisheries Science Center (NEFSC).

“These high sea surface temperatures (SSTs) are the latest in a trend of above average temperature seen during the spring and summer seasons, and part of a pattern of elevated temperatures occurring in the Northwest Atlantic, but not seen elsewhere in the ocean basin over the past century,” said the latest NEFSC advisory.

  • The temperature rise in 2012 was the highest temperature jump—more than 1°C—ever  observed in the time series.
  • Average SST was lower than 12.4°C (54.3°F) over the past three decades.
  • The Northeast U.S. Continental Shelf Large Marine Ecosystem (LME) extends from the Gulf of Maine to Cape Hatteras, N.C.

The warm water thermal habitat reached a record high during 2012, while cold water habitat dropped to a record low. “Early winter mixing of the water column went to extreme depths, which will impact the spring 2013 plankton bloom. Mixing redistributes nutrients and affects stratification of the water column as the bloom develops,” said the report.

Distributions of fish and shellfish on the Shelf is also affected by temperature. “The four southern species – black sea bass, summer flounder, longfin squid and butterfish – all showed a northeastward or upshelf shift. American lobster has shifted upshelf over time but at a slower rate than the southern species. Atlantic cod and haddock have shifted downshelf.”

“Changes in ocean temperatures and the timing and strength of spring and fall plankton blooms could affect the biological clocks of many marine species, which spawn at specific times of the year based on environmental cues like water temperature,” said a researcher in the NEFSC Ecosystem Assessment Program.

Past Decade Warmest on Record

Posted by feww on July 29, 2010

Earth has been growing warmer since the 1950s

Past Decade Warmest on Record According to Scientists in 48 Countries: NOAA

The 2009 State of the Climate report highlights 10 key climate indicators based on scientific evidence that the world is warming.  “More than 300 scientists from 160 research groups in 48 countries contributed to the report, which confirms that the past decade was the warmest on record and that the Earth has been growing warmer over the last 50 years.” A Report said.

This is one of a very few worthwhile studies carried out by the scientific community. Alas, they only tell you the result when it’s practically too late to do much about it.

Ten Indicators of a Heating World

“The temperature increase of one degree Fahrenheit over the past 50 years may seem small, but it has already altered our planet,” said Deke Arndt, co-editor of the report and chief of the Climate Monitoring Branch of NOAA’s National Climatic Data Center. “Glaciers and sea ice are melting, heavy rainfall is intensifying and heat waves are more common. And, as the new report tells us, there is now evidence that over 90 percent of warming over the past 50 years has gone into our ocean.”

Verifiable Impacts of Climate Change (Part II)

Climate Change Indicators

Impact of Climate Change Despite the Massive Efforts by Fossil Fuel Industries to Spread Disinformation

Key Findings: Climate Change Indicators in the United States Report

Sea Surface Temperature


The surface temperature of the world’s oceans increased over the 20th century. Even with some year-to-year variation, the overall increase is statistically significant, and sea surface temperatures have been higher during the past three decades than at any other time since large-scale measurement began in the late 1800s.

Sea Level


Average sea level worldwide has increased at a rate of roughly six-tenths of an inch per decade since 1870. The rate of increase has accelerated to more than an inch per decade in recent years. Changes in sea level relative to the height of the land vary widely because the land itself moves. Along the U.S. coastline, sea level has risen the most relative to the land along the Mid-Atlantic coast and parts of the Gulf Coast, while sea level has decreased relative to the land in parts of Alaska and the Northwest.

Ocean Acidity


The ocean has become more acidic over the past 20 years, and studies suggest that the ocean is substantially more acidic now than it was a few centuries ago. Rising acidity is associated with increased levels of carbon dioxide dissolved in the water, can affect sensitive organisms such as corals.

Arctic Sea Ice


Part of the Arctic Ocean stays frozen year-round. The area covered by ice is typically smallest in September, after the summer melting season. September 2007 had the least ice of any year on record, followed by 2008 and 2009. The extent of Arctic sea ice in 2009 was 24 percent below the 1979 to 2000 historical average.

Glaciers


Glaciers in the United States and around the world have generally shrunk since the 1960s, and the rate at which glaciers are melting appears to have accelerated over the last decade. Overall, glaciers worldwide have lost more than 2,000 cubic miles of water since 1960, which has contributed to the observed rise in sea level.

Lake Ice


Lakes in the northern United States generally appear to be freezing later and thawing earlier than they did in the 1800s and early 1900s. The length of time that lakes stay frozen has decreased at an average rate of one to two days per decade.

Snow Cover


The portion of North America covered by snow has generally decreased since 1972, although there has been much year-to-year variability.

Snowpack


Between 1950 and 2000, the depth of snow on the ground in early spring decreased at most measurement sites in the western United States and Canada. Spring snowpack declined by more than 75 percent in some areas, but increased in a few others.

Heat-Related Deaths


Over the past three decades, more than 6,000 deaths across the United States were caused by heat-related illness such as heat stroke. However, considerable year-to-year variability makes it difficult to determine long-term trends.

Length of Growing Season


The average length of the growing season in the lower 48 states has increased by about two weeks since the beginning of the 20th century. A particularly large and steady increase has occurred over the last 30 years. The observed changes reflect earlier spring warming as well as later arrival of fall frosts.

Plant Hardiness Zones


Winter low temperatures are a major factor in determining which plants can survive in a particular area. Plant hardiness zones have shifted noticeably northward since 1990, reflecting higher winter temperatures in most parts of the country.

Leaf and Bloom Dates


Leaf growth and flower blooms are examples of natural events whose timing can be influenced by climate change. Observations of lilacs and honeysuckles in the lower 48 states suggest that leaf growth is now occurring a few days earlier than it did in the early 1900s. Lilacs and honeysuckles are also blooming slightly earlier than in the past, but it is difficult to determine whether this change is statistically meaningful.

Bird Wintering Ranges


Some birds shift their range or alter their migration habits to adapt to changes in temperature or other environmental conditions. Long-term studies have found that bird species in North America have shifted their wintering grounds northward by an average of 35 miles since 1966, with a few species shifting by several hundred miles.

What do these changes translate into in layman terms?
