"The UN claims climate change is 'almost definitely' caused by humans, and now Google Earth users can see the impact they are supposed to have made to temperature changes in their local area. Climate researchers at the University of East Anglia have added the world's temperature records as a layer on the mapping service. It lets users zoom into 6,000 global weather stations and see monthly, seasonal and annual temperature changes dating back to 1850."

"A brutal and potentially historic heat wave is in store for the West as parts of Nevada, Arizona and California may get dangerously hot temperatures starting Thursday and lasting through next week. In fact, by the end of the heat wave, we may see a record tied or broken for the hottest temperature ever recorded on Earth."

"An analysis of global temperatures by NASA scientists shows that 2013 was the seventh warmest year since 1880 (tied with 2006 and 2009). Nine of the 10 warmest years on record all have occurred since 2000, with 2010 and 2005 ranking as the warmest. Scientists at NASA's Goddard Institute for Space Studies (GISS) reported that 2013 continued the long-term trend of rising air temperatures over the land and sea surface. This animation shows monthly temperature anomalies from 1880 through 2013."

"One of the most common misunderstandings amongst climate change "skeptics" is the difference between short-term noise and long-term signal.  This animation shows how the same temperature data (green) that is used to determine the long-term global surface air warming trend of 0.16°C per decade (red) can be used inappropriately to "cherrypick" short time periods that show a cooling trend simply because the endpoints are carefully chosen and the trend is dominated by short-term noise in the data (blue steps).  Isn't it strange how five periods of cooling can add up to a clear warming trend over the last 4 decades?  Several factors can have a large impact on short-term temperatures, such as oceanic cycles like the El Niño Southern Oscillation (ENSO) or the 11-year solar cycle.  These short-term cycles don't have long-term effects on the Earth's temperature, unlike the continuing upward trend caused by global warming from human greenhouse gas emissions."

"For the first time, researchers have put together all the climate data they have (from ice cores, coral, sediment drilling) into one chart that shows the "global temperature reconstruction for the last 11,000 years":"

"You've likely seen the graph of the Earth's average global temperature over the past 2000 years...it's mostly a straight line until you get to the industrial revolution and then it shoots up. It looks like a hockey stick. In a study published today in Science, that graph has been extended back 11,300 years and you can really see the scope of the abrupt temperature change."

"The world experienced unprecedented high-impact climate extremes during the 2001-2010 decade, which was the warmest since the start of modern measurements in 1850 and continued an extended period of pronounced global warming. More national temperature records were reported broken than in any previous decade, according to a new report by the World Meteorological Organization (WMO). The report, The Global Climate 2001-2010, A Decade of Climate Extremes, analysed global and regional temperatures and precipitation, as well as extreme events such as the heat waves in Europe and Russia, Hurricane Katrina in the United States of America, Tropical Cyclone Nargis in Myanmar, droughts in the Amazon Basin, Australia and East Africa and floods in Pakistan."

When I testified before the US Senate in the hot summer of 1988, I warned of the kind of future that climate change would bring to us and our planet. I painted a grim picture of the consequences of steadily increasing temperatures, driven by mankind's use of fossil fuels. But I have a confession to make: I was too optimistic. My projections about increasing global temperature have been proved true. But I failed to fully explore how quickly that average rise would drive an increase in extreme weather.

"From record hot and cold temperatures to floods and droughts, 2013 was a wacky year for weather. The National Oceanic and Atmospheric Administration (NOAA) weighed in Wednesday with its list of the year's most significant climate anomalies and events. The report puts specific weather events into historical context, with the general effect of suggesting that global temperature rise is driving heightened weather extremes."

"The science behind what makes our planet's temperature rise is pretty straightforward. Pollutants like soot and greenhouse gases like methane and carbon dioxide trap heat within the earth's atmosphere, the global average surface temperature goes up, ice caps melt, sea levels rise and extreme weather events become even more extreme. However, American college students are coming with with some of the coolest ways to battle climate change and clean up domestic energy production."

"Climate change in Australia provides essential tools for government, industry and the community to understand the likely magnitude of climate change in Australia and the possible impacts." It studies Temperature, Rainfall, Humidity, Sea surface Temperature, Wind speed, Potential evapotranspiration, Downward solar radiation

""If the average temperature of a large body of water increases, that's an enormous amount of heat content," says Andrew Rosenberg, a convening lead author of the National Climate Assessment's Oceans chapter. Ocean waters are becoming warmer and more acidic, broadly affecting ocean circulation, chemistry, ecosystems, and marine life. Rising sea surface temperatures have been linked with increasing levels and ranges of diseases in people and marine life. In this video, Rosenberg discusses how human-caused climate change is transforming the oceans that make up 70 percent of the Earth's surface."

"Global drought has not increased significantly over the past 60 years, a report in Nature has found. Previous assessments of global drought have relied on the Palmer Drought Severity Index, which only accounts for temperature, and does not consider sunlight, humidity or wind. These assessments have falsely indicated that global drought will increase as the planet warms. The paper's authors show that when these additional factors are included, worldwide drought has actual changed very little since 1950."

"Global warming has propelled Earth's climate from one of its coldest decades since the last ice age to one of its hottest -- in just one century. A heat spike like this has never happened before, at least not in the last 11,300 years, said climatologist Shaun Marcott, who worked on a new study on global temperatures going back that far."

"When extreme weather events occur the Climate Commission is consistently asked questions about the link to climate change. This report unpacks our current knowledge about different types of extreme weather events: extreme temperatures, rainfall, drought, bushfires, storm surges, cyclones and storms."

"Some of the most extreme predictions of global warming are unlikely to materialise, new scientific research has suggested, but the world is still likely to be in for a temperature rise of double that regarded as safe."

"The World Meteorological Organization just released its Global Climate Report (pdf), which wastes no time in announcing a stark truth. The report's first sentence: "The first decade of the 21st century was the warmest decade recorded since modern measurements began around 1850." Nine out of ten years between 2001 and 2010 were among the ten warmest in recorded history, according to the report, and the warmest year to date was 2010. For those worried about glacier melting, the heat spike wasn't isolated to land. The decade was warmest for both land and ocean surface temperatures. In case anyone still doubts the existence of global warming, take a gander at this chart:"

"Australia is belatedly waking up to the implications of the carbon budget, although the concept has been around for years. It simply says that if the increase in global temperature resulting from human carbon emissions is to be contained to a level which will prevent dangerous climate change, the world, henceforth, can only afford to emit a limited amount of greenhouse gases. According to the latest science, that limit will be exceeded if we burn more than 20 per cent of the world's proven coal, oil and gas reserves. This is confirmed in recent reports from the International Energy Agency and Australia's Climate Commission."
