According to the 2009 National Climate Assessment, heavy downpours have increased in frequency and intensity during the last 50 years. Models predict that downpours will become still more more frequent and intense as greenhouse gas emissions and the planet’s temperature continue to rise.
How do we know we can trust the historical surface temperature record? Did global warming stop in 1998? What actions can businesses or individuals take to reduce climate chagne from greenhouse gas emissions? Get asnwers to these and other frequently asked questions.
The most likely explanation for the lack of significant warming at the Earth’s surface in the past decade or so is that natural climate cycles caused shifts in ocean circulation patterns that moved some excess heat into the deep ocean.
Each of the last three decades was warmer than all earlier decades in the instrumental record, and each set a new and statistically significant record, culminating in the 2000s, which was the warmest decade of all.
WMO Releases Annual Status of the Global Climate Report

The dramatic impact of climate variability and climate change continued to be felt all over the world throughout 2013.The World Meteorological Organization statement on the status of the global climate in 2013 provides a snapshot of global and regional trends in weather and climate over the past year and highlights some of the year’s most significant extreme events.
A team of climate scientists from The National Academy of Sciences and The Royal Society have produced a new report for decision makers, policy makers, educators, and other individuals seeking authoritative information on climate science.
