Last summer, James Hansen—the pioneer of modern climate science—pieced together a research-based revelation: a little-known feedback cycle between the oceans and massive ice sheets in Antarctica and Greenland might have already jump-started an exponential surge of sea levels. That would mean huge levels of sea level rise will happen sooner—much sooner than expected.

An undercover sting by Greenpeace has revealed that two prominent climate sceptics were available for hire by the hour to write reports casting doubt on the dangers posed by global warming.
Posing as consultants to fossil fuel companies, Greenpeace approached professors at leading US universities to commission reports touting the benefits of rising carbon dioxide levels and the benefits of coal. The views of both academics are well outside mainstream climate science.
Every part of the mosaic of Earth's surface—ocean and land, Arctic and tropics, forest and grassland—absorbs and releases carbon in a different way. Wild-card events such as massive wildfires and drought complicate the global picture even more. To better predict future climate, we need to understand how Earth's ecosystems will change as the climate warms and how extreme events will shape and interact with the future environment. Here are seven pressing concerns.
Chapala, now the unprecedented 23rd category 4 or category 5 tropical cyclone to form during 2015, is bearing down on the nation of Yemen. A nation that is likely to experience hurricane force winds and may receive as much as 8 years worth of rainfall from Chapala’s intense spiral bands over a 24-48 hour period.
Now this is scary. A tragic development you’d tend to see in a disaster movie screenplay and not in any typical meteorological record for any 36 hour period. But here we have it.
Patricia, as of 36 hours ago, was a rather mild tropical storm churning through the human hothouse and El Nino warmed Eastern Pacific. The storm was predicted to make landfall in Western Mexico as a hurricane, then turn north into Texas, Louisiana and Mississippi — dumping extreme rains over a drought stricken region. But there was little hint as to what would happen next.
From end 2014 through Fall of 2015 global sea levels surged. Building heat hitting +1 C above 1880s averages in the atmosphere-ocean system continued to set off a range of what appear to be ramping impacts. Thermal expansion grew more dramatic as oceans continued to heat up during what may be a record El Nino year. Rates of land ice melt continued to increase — providing a greater and greater fraction of overall global sea level rise.
Back in 1990, as the debate over climate change was heating up, a dissident shareholder petitioned the board of Exxon, one of the world’s largest oil companies, imploring it to develop a plan to reduce carbon dioxide emissions from its production plants and facilities.
The board’s response: Exxon had studied the science of global warming and concluded it was too murky to warrant action. The company’s “examination of the issue supports the conclusions that the facts today and the projection of future effects are very unclear.”
