The warming temperatures of the ocean are problematic for many species, but especially worrisome is the impact hotter water has on cornerstone species upon which many other marine animals rely. Usually we hear about changes in ocean temperature impacting coral reefs, but now scientists are finding that across the globe, phytoplankton -- the food for zooplankton which is food for many other ocean species -- is in decline, and that will have massive impacts for not just the marine food chain but ocean systems on the whole.

is our current heat wave a symptom of global warming?
Here’s what most scientists say is certain:
The Earth is warming, by 1.4-degrees Fahrenheit since 1920
The ice caps are melting and sea levels are rising
10 of the last 12 years were the warmest since 1850
The first six months of 2006 were the hottest since they started keeping records in 1890.
"This heat wave and other extreme events we've seen in recent years are completely consistent with what we expect to become more common as a result of global warming, even though we can't be definitive on any single event,” says Jay Gulledge with Pew Climate Change.

In this five part video interview on CNN, Carl Sagan talks with Ted Turner about Global Warming, CO2 gas and the insane idea of nuclear war. He quickly illustrates how just a few hundred nuclear weapons would create a nuclear winter, which would not only destroy the nation on the receiving end of the bombs, but also the nation who launched them. All of this makes me think about how short term greed by the small number of people at the top, effects us all. Instead of using our minds and abilities to build a green future, we waste our time thinking of new ways to destroy the only planet we can call home.

For the first time, a causal link has been established between climate change and the timing of a natural event – the emergence of the common brown butterfly.

Although there have been strong correlations between global warming and changes in the timing of events such as animal migration and flowering, it has been hard to show a cause-and-effect link. This is what Michael Kearney and Natalie Briscoe of the University of Melbourne, Australia, have now done.

public opinion data on global warming also points in one direction: Americans support investments in clean energy, and want action to reduce global warming pollution. Poll after poll finds majorities support these measures, despite the worst economy in eighty years, and $100 million and growing of big oil and coal advocacy to defeat clean energy and global warming legislation.

Temperatures in Tibet rose last year to the highest level since records began for the remote Himalayan country, which scientists say is particularly vulnerable to global warming, state media reported on Friday.

Wintertime can often prove a headache for anyone in the business of trying to find solutions to human-caused climate change. It is, after all, when people step outside and notice that it's cold, and instinctively think "Man, global warming is a crock." Eventually, such sentiments get echoed in the mainstream media, and scientists and climate journalists must step in and explain that just because it's cold out right now doesn't mean climate change isn't happening. Think of it as an annual ritual. This year has been even worse, with Northern Europe and North America seeing record cold temperatures from a negative arctic oscillation. But don't take my word for it--watch this excellent video on why a cold snap doesn't disprove global warming after the jump.

"With the world losing the battle against global warming so far, experts are warning that humans need to follow nature's example: Adapt or die.

That means elevating buildings, making taller and stronger dams and seawalls, rerouting water systems, restricting certain developments, changing farming practices and ultimately moving people, plants and animals out of harm's way.

More than $200-billion worth of Canadian assets are at risk from global warming, says an international report released Monday.

The research was prepared for WWF-Germany and Allianz Group by the Tyndall Centre for Climate Change Research in the United Kingdom.

"The world's largest ice sheet has started to melt along its coastal fringes, raising fears that global sea levels will rise faster than scientists expected.

The East Antarctic ice sheet, which makes up three-quarters of the continent's 14,000 sq km, is losing around 57bn tonnes of ice a year into surrounding waters, according to a satellite survey of the region."

"A number of very large cities in Asia are "extremely exposed to threats such as storms and flooding", according to a new report by global conservation organization WWF.

"Climate change is already shattering cities across developing Asia and will be even more brutal in the future. These cities are vulnerable and need urgent help to adapt, in order to protect the lives of millions of citizens, a massive amount of assets, their large contributions to the national GDP," says Kim Carstensen, leader of the WWF Global Climate Initiative, at the organization’s homepage."

"The annual Climate Confidence Monitor found the number of people worrying about global warming worldwide has fallen by eight per cent to just over a third in the last year as the economic downturn kicked in.

Just fifteen per cent of people in Britain worry about climate change and how the world responds to the problem, the lowest figure for any of the 12 countries surveyed. The figure is down from 26 per cent last year."

South Africa appears to have softened its position on greenhouse gas emissions, saying on Wednesday it would support cuts to prevent global warming.

"On global warming, cabinet would like to correct the wrong impression that had been created that South Africa was opposed to targets being set on global warming," cabinet spokesman Themba Maseko told journalists, according to Reuters.

Countries which are contributing most to climate change, including Britain, will be shielded from its worst effects, according to a study which ranks nations according to their vulnerability to global warming.

The poorest countries, including most of Africa and much of south Asia, face “extreme risk” from climate change despite having very low greenhouse gas emissions.
